An Easy & Thorough Guide On What Is Data Engineering?

Before a model is created, before the existing data is cleaned and made ready for exploration, even before the responsibilities of a data scientist start – this is where data engineers come into the frame. In this article, we are going to have a look at what is data engineering. 

Every data-driven business requires a framework in place for the flow of data science, otherwise, it is a setup for failure. Most people enter the data science niche with the focus of becoming a data scientist, without ever knowing what is data engineering and analytics are and what the role of a data engineer is. They are crucial parts of any data science venture and their demand in the sector is evolving exponentially in the present data-rich scenario. 

There is presently no coherent or official path available for data engineers. Most people in this role reach there by learning on the job, rather than abiding by a detailed avenue.

What Is Data Engineering?

A data engineer is responsible for constructing and maintaining the data frame of a data science project. These engineers have to make sure that there is an uninterrupted flow of data between applications and servers. Some of the responsibilities of a data engineer involve enhancing data foundational procedures, including the latest data management technologies and also software into the prevailing mechanism, and constructing data collection pipelines among various other things.

One of the most crucial skills in data engineering is the potential to design and construct data warehouses. This is where all the raw data is collected, kept, and retrieved. Without data warehouses, all the activities that a data scientist does will become either too pricey or too big to scale. 

Extract, Transform, and Load (ETL) are the steps that are followed by a data engineer to construct the data pipelines. ETL is crucially a blueprint for how the assembled data is processed and changed into data ready for the purpose of analysis. 

Data engineers usually have an engineering background. Unlike data scientists, there is not much scientific or academic evaluation needed for this role. Engineers or developers who are interested in constructing large-scale frameworks and architecture are ideal for this role.

Difference Between Data Scientist & Data Engineer

 It is crucial to know the difference between these 2 roles. Broadly speaking, a data scientist formulates models using a combination of statistics, machine learning, mathematics, and domain-based knowledge. He or she has to code and construct these structures using similar tools or languages and also structures that the team supports. 

A data engineer on the contrary has to maintain and build data frameworks and architectures for the purpose of data ingestion, processing, and deploying of large-scale data-heavy applications. Construct a pipeline for data storage and collection, funnel the data to the data scientist, to put the structure into production – these are just some of the activities a data engineer has to do.

Role Of A Data Engineer

  • What are your strengths and weaknesses?

These are just examples. You can do your research or ask professionals in your network to find the most common questions. This will surely make you more confident about your data science interview preparation.

 

6. Improve Your Body Language

Albert Mehrabian, a professor of Psychology, found that communication is 55% body language, 38% tone of voice, and 7% words only. 

So, while your technical skills and experience are important, your body language can make or break your chances of success in the interview. 

Here are simple ways to improve your body language:

  • Make eye contact with the interviewer when listening or speaking to them.
  • Sit straight with your shoulders back and your feet flat on the floor.
  • Use natural hand gestures to emphasize points or express enthusiasm.
  • Smile and nod to show that you are listening and you have a positive attitude.
  • Speak clearly and at a moderate pace. Avoid words like “um” or “uh.”

Your body language shows your confidence and attitude, so try to make it perfect.

 

7. Practice Mock Interviews

Mock interviews can boost your data science interview preparation. It helps you improve your answers and body language, increase confidence, and get used to the scary interview environment. 

You can simply practice it with your friends or do it alone by recording yourself while you speak. But the best way to do it is to join a course where they let you practice mock interviews. 

For instance, Ivy Pro’s Data Science Course with IIT Guwahati helps you practice mock interviews and learn soft skills. This way, you get feedback to understand your strengths and areas of improvement.

Easy Evaluation Of The Basics Of Stock Market Data Analytics

Everywhere we read, we see the power of data science. Data science is changing the world we are living in. Everyone is concerned about data. Businesses are keen on evaluating how data can help them to cut off expenses and enhance their bottom line. Businesses from every niche are now interested in data science and the stock market is no different. In this article, we will have a look at stock market data analytics and how it boosts the graphs of the stock market. 

Data science is typically portrayed in numbers. But these numbers should imply anything that ranges from the number of users who buy a product to the amount of inventory that is sold. Of course, these numbers should also portray cash. 

Now coming to stock market data analytics. Here we can either sell, buy, or hold. The aim is to make the biggest profit possible. The question that many are aiming to answer is about the role that data science plays in helping us conduct trades in the stock market. Trading platforms have become very famous in the last two decades, but each platform provides varied options, fees, tools, and many more. Despite the evolving trend, there are many nations that have still not been able to access zero trading commission platforms. This article is based on stock market data analytics India.

Understanding The Basics When Dealing With Stock Market Data Analytics

There are numerous phrases that are used in data science that a person would be required to be a scientist to understand. At its most primary level, data science is mathematics that is carved with an understanding of statistics and programming. 

There are various concepts in data science that are applied when analysing the market. In this respect, we are employing the term “analyze” to evaluate whether it is worth it to make investment in it. There are some primary data science ideas that are ideal to be familiar with.

Basics of Stock Market Data Analytics

Algorithms

Algorithms are utilized extensively in data science. Basically an algorithm is a group of regulation required to perform a task. You have mostly heard about algorithms being used when purchased and selling stocks. Algorithmic trading is where algorithms fix rules for things such as when to purchase a stock or when to sell a stock. 

For instance, an algorithm could be created to buy a stock once it drops by 8% in the entire day or to sell the stocks if it loses 10% of its value in comparison to when it was bought initially. Algorithms are formed to operate without human intervention. You might have heard about them referred to as bots. Like robots, they make calculated decisions that are devoid of emotions.

Training

We are not discussing preparing to operate a 50 metre race. In ML (Machine learning) and also data science, training is where data is utilized in training a machine on how to revert back. We can formulate a learning structure. This machine learning framework makes it possible for a computer to offer accurate predictions that are based on the data it learned from the past. If you wish to teach a machine to anticipate the future of the values of stocks, it would require a structure of the stock prices of the last year to utilise as a base to anticipate what will occur.

Testing

Let us start with a stock market data analysis project. We have the real data for stock values from the previous year. The training set would be the real data from January to October. Then the data from November to December can be used for any testing set. Our machines should have understood by assessing how the stocks operated from January through October. Now, we will ask our machines to anticipate what should have occurred in November and December of that year. The predictions that will be made by the machine will be then compared to real values. The amount of variation seen in the prediction of the model and the real data are what we are aiming to discard as we adjust our training framework.

Stock Market Data Analytics: The Role Of Modeling To Anticipate Stock Prices

Data science depends heavily on structuring. This is a strategy that uses mathematics to examine previous behaviours with the aim of forecasting upcoming results. In the stock market, a time series model is employed. 

A time series is basically data which in this scenario refers to the value of a stock that is indexed over a span of time. This span of time could be divided on an hourly, daily, monthly, or even minute basis. A time series module is formulated by using machine learning or deep learning models to fit the time data. The data requires to be analyzed and then fitted to match the structure. This is why it is effective to anticipate future values of stocks over a fixed timetable.  

A second form of modeling that is employed in data science and machine learning  is termed as a classification structure. These structures are offered data points and they aim to anticipate or classify what is portrayed by those data points. 

When talking about the stock market or even stocks in general, a ML framework can be given financial data such as the P/E ratio, volume, total debt, and many more and then evaluate if you are making a sound investment. Depending on the basic financials we offer, a model can evaluate if now is the time to hold, sell, or purchase a stock. 

A model could anticipate something with so many complications that it overlooks the relationship between the feature and the target variable. This is termed as overfitting. Underfitting is where a framework does not sufficiently cater to the data, so the outcomes are anticipations that are very simple.  

Overfitting is an issue in stock market data analytics if the model finds it hard to identify stock market trends, so it cannot adapt to future incidents. It is where a structure anticipates the simple average price that is based on the complete history of the stocks. Both overfitting & underfitting lead to poor anticipations and forecasts.

Wrapping Up

We have barely scratched the surface when talking about the connection between machine learning ideas and stock market investments. However, it is crucial to evaluate the primary concepts  we have discussed previously as they cater as a basis for comprehending how ML is employed to anticipate what the stock market can do. There are more ideas that can be learned by those who wish to receive the nitty-gritty stock market data analytics.

What Is Keras & Why Is It So Popular Presently?

Keras is an easy-to-use, strong, free open-source Python library for evaluating and developing deep learning frameworks. This is a part of the TensorFlow library and enables you to illustrate and train neural network structures in just some lines of code. In this article, we will be talking about what is Keras and TensorFlow.

Principles Of Keras

Let us start this Keras tutorial. Keras was formulated to be quite user-friendly, easy to extend, modular, and to work with Python. The API was “designed  for human beings, not machines” and “follows best practices for reducing cognitive load.”

Neural layers, optimizers, cost operations, activation operations, initialization schemes, and regularization schemes are all standalone structures that one can combine to formulate a new module. New modules are easy to add, as new functions and classes. Models are illustrated in Python code, not different structure configuration models. 

In this article on what is Keras in Python, let us have a look at the key features of Keras:

  • Modularity: Modules required for creating a neural network are involved in an interface so that it is more convenient to use for the end user. 
  • Minimalistic: Implementation is short and concise. 
  • Extensibility: It is very ideal for advanced research and also it is very convenient to write a new module for Keras.

Advantages Of Keras

Being a high-level library and is a convenient interface, Kears certainly boosts as one of the deep learning libraries that is available. There are several features of itself, which makes it more convenient to use and also offers more features. 

– If Keras is compared with   and Theano, it tries to offer a better “user Experience” and this zones Keras above the other two libraries. 

– As this is a Python library, it is more available to the general public because of the inherent simplicity of the Python programming language. 

– Lasagne is a library that is very similar to Kears. But using both the libraries I can say Keras is much more convenient.

Disadvantages Of Keras

Now that you know the advantages of using the Keras library, you should also be aware of the disadvantages of Kears.

– Since this Python library has its dependency on low-level languages such as TensorFlow and Theano, so this performs as a double-edged sword for Keras. This is the primary reason why Keras cannot move beyond the realms of these libraries. For instance, both TensorFlow and Theano presently do not support GPUs except Nvidia. That is the reason Keras also does not have the corresponding support. 

– Similar to Lasagne, eras also wholly abstract the low, level languages. So this is less flexible when it comes to creating custom functions. 

– The final point is that this is new in this niche. Its very first version was launched in late 2015, and it has gone through various alterations since then. Then even though Keras is already used in the process of production, one should always think twice before they deploy Keras models for production.

What Is Keras: Keras Model Overview

keras-model-overview
Keras Model Overview

Models are the primary entity one will be working with when using Keras. The structures are used in defining TensorFlow neural networks by mentioning the attributes, operations, and layers you wish. 

Keras provides a range of APIs you can employ to illustrate your neural network, involving:

– Sequential API allows one to formulate a model structure by structure for most issues. It is straightforward but restricted to single-input, single-output stacks of layers. 

– Functional API is mainly a full-feature API that supports arbitrary framework architecture. It is more complicated and flexible in comparison to the sequential API. 

– Model Subclassing allows one to enact everything from scratch. Ideal for research and highly complicated use scenarios, but it is hardly used in practice.

What Is Keras? Solving General Problems With Neural Networks

ML (Machine Learning) algorithms use a special form of an algorithm that is known as a Neural Network. Same as every machine learning algorithm, it also abides by the general ML workflow of data preprocessing and model evaluation. For ease of use, here are some of the to-dos on how to approach a Neural Network problem. 

– See if there are issues where a neural network offers you an uplift over traditional algorithms. 

– Conduct a survey for which neural network architecture is the most ideal required issue. 

– Illustrate neural network architecture via language or library as per your choice.

– Change data into the ideal format and divide it into varied batches.

– As per your requirements, pre-process the data.

– Augmented data is utilized to magnify size and make better-trained frameworks. 

– Batches are nourished by the neural network.

– Track alterations in training and validation data sets, and also train them.

– Test your frameworks.

Wrapping Up

After this article on what is Keras model, you come to know about how this is useful in the area of deep learning along with its benefits and also limitations. We have also seen how this Python library depends on low-level languages such as Theanos and TensorFlow. Also if you were wondering what is Keras vs TensorFlow, then you must have got your answer. 

Career prospects in data science and data analytics have increased over time and this has become a much-acclaimed niche presently. If you wish to start your career in data science then there can be no better place than Ivy Professional School. It offers a complete course on data science conducted by industry experts.

What is Scikit-learn: An introduction for beginners

Updated in May, 2024

Do you know Netflix and Spotify use the Scikit-learn library for content recommendations? 

Scikit-learn is a powerful machine learning library in Python that’s primarily used for predictive analytics tasks such as classification and regression.

If you are a Python programmer or aspiring data scientist, you must master this library in depth. It will help you with projects like building content-based recommendation systems, predicting stock prices, analyzing customer behavior, etc.

In this blog post, we will explain what is Scikit-learn and what it is used for. So, let’s get started…

 

What is Scikit-Learn?

Scikit-learn is an open-source library in Python that helps us implement machine learning models. This library provides a collection of handy tools like regression and classification to simplify complex machine learning problems.

For programmers, AI professionals, and data scientists, Scikit-learn is a lifesaver. The library has a range of algorithms for different tasks, so you can easily find the right tool for your problem.

Now, there is often a slight confusion between “Sklearn” and “Scikit-learn.” Remember, both terms refer to the same thing: an efficient Python library.

Although Scikit-learn is specifically designed to build machine learning models, it’s not the best choice for tasks like data manipulation, reading, or summary generation.

Scikit-learn is built on the following Python libraries:

  • NumPy: Provides the foundation for arrays and mathematical functions.
  • SciPy: Offers advanced scientific and technical computing tools.
  • Matplotlib: A versatile library for creating visualizations.

Scikit-learn was developed with real-world problems in mind. It’s user-friendly with a simple and intuitive interface. It improves your code quality, making it more robust and optimizing the speed.

Besides, the Scikit-learn community is supportive. With a massive user base and great documentation, you can learn from others and get help when you need it. You can discuss code, ask questions, and collaborate with developers.

 

The History of Scikit-Learn 

Scikit-learn was created by David Cournapeau as a “Google Summer Of Code” project in 2007. It quickly caught the attention of the Python scientific computing community, with others joining to build the framework.

Since it was one of many extensions built on top of the core SciPy library, it was called “scikits.learn.” 

Matthieu Brucher joined the project later, and he began to use it as a part of his own thesis work. 

Then, in 2010, INRIA stepped in for a major turning point. They took the lead and released the first public version of Scikit-learn. 

Since then, its popularity has exploded. A dedicated international community drives its development, with frequent new releases that improve functionality and add cutting-edge algorithms.

Scikit-learn development and maintenance is currently supported by major organizations like Microsoft, Nvidia, INRIA foundation, Chanel, etc.

 

What is Scikit-Learn Used for?

The Scikit-learn library has become the de facto standard for ML (Machine Learning) implementations thanks to its comparatively easy-to-use API and supportive community. Here are some of the primary uses of Scikit-learn:

  • Classification: It helps sort data into categories and identify the right place a data point belongs. Common examples are programs that detect email spam, recognize images, etc.
  • Regression: It’s used to find the relationship between output and input data. For example, you could use Scikit-learn to predict housing prices based on features like the number of bedrooms. It can also be used to predict stock prices and sales trends.
  • Clustering: It automatically groups data with similar features into sets without knowing the categories beforehand. This could help identify customer segments in a marketing dataset or discover hidden patterns in scientific data.
  • Dimensionality Reduction: It simplifies complex datasets by reducing the number of random variables. This makes data easier to visualize, speeds up model training, and can improve performance.
  • Model Selection: It helps you compare different machine learning algorithms and automatically tune their settings to find the best fit for your data. This optimizes the accuracy of your predictions.
  • Preprocessing: It helps us prepare data for machine learning algorithms. These tools are useful in feature extraction and normalization at the time of data analysis. Tasks like transforming text into numerical features, scaling data, or handling missing values can be done by the library.

How to Use Scikit-Learn in Python?

Here’s a small example of how Scikit-learn is used in Python for Logistic Regression:

from sklearn.linear_model import LogisticRegression; model = LogisticRegression().fit(X_train, y_train)

Explanation:

  • from sklearn.linear_model import LogisticRegression: It imports the Logistic Regression model from scikit-learn’s linear_model module. 
  • model = LogisticRegression().fit(X_train, y_train): It creates a Logistic Regression classifier object (model).
  • .fit(X_train, y_train): It trains the model using the features in X_train and the corresponding target labels in y_train. This essentially lets the model learn the relationship between the features and the classes they belong to (e.g., spam vs not spam emails).

Now, you must have understood what is Scikit-learn in Python and what it is used for. Scikit-learn is a versatile Python library that is widely used for various machine learning tasks. Its simplicity and efficiency make it a valuable tool for beginners and professionals.

An Easy & Detailed Guide On What Is TensorFlow

Machine learning is a complicated drill, but enacting machine learning structures is far less scary than it previously was because of the machine learning framework like Google’s TensorFlow. This framework eases the process of obtaining the data, training models, serving anticipations, and refining future outcomes. In this article, we will have a detailed look at what is TensorFlow and how it operates. 

Formulated by the Google Brain team and primarily released to the audience in 2015, TensorFlow is an open-source library for numerical computation and large-scale ML. TensorFlow bundles together a range of deep learning and machine learning structures and also algorithms and makes them useful by way of relevant programmatic metaphors. It employs JavaScript or Python to offer an easy front-end API for constructing applications while implementing those apps in high-performance C++. Let us now start with tensor flow basics.

History Of TensorFlow

Let us begin this article on what is TensorFlow by knowing about his history. Many years ago, deep learning began to exceed all other ML algorithms when offering extensive data. Google has found it could utilize these deep neural networks to upgrade its services:

  1. Google Search Engine
  2. Gmail
  3. Photos

They constructed a framework known as TensorFlow to allow researchers and also developers to operate together in an AI structure. Once it is approved and is scaled, it enables a lot of people to employ it. 

OIT was initially launched in 2015 while the first stable version came in 20170. It is an open-source platform under Apache Open Source Licence. The users can use it, modify it, and reorganise the revised variant for free without paying anything to Google.

Components Of TensorFlow

To understand what is TensorFlow, you should first know about the various components of TensorFlow. So without any further delay, let us begin with this guide.

Tensor

The name TensorFlow is obtained from its basic framework, “Tensor.” A tensor is basically a vector or matrix of n-dimensional that portrays all forms of data. Every value in a tensor holds a similar type of data with a relevant shape. The shape of the data is the dimension of the matrix or even an array. 

A tensor can be developed from the outcome or the input data of a computation. In this data analytics framework, all tensor flow uses are conducted within a graph. The group is a set of calculations that occurs successively. Every transaction known as an op node is linked. 

Graphs

TensorFlow makes use of a graph structure. The chart assembles and also illustrates all the computations done at the time of the training.

Benefits

  • It was fixed to operate on various GPUs and CPUs and mobile OS. 
  • The portability of the graph enables it to conserve the computations for present or later use. The graph can further be saved as it can be implemented in the future. 
  • All the computations in that graph are made by connecting tensors together. 

You can consider the following expressions a= (b+c)*(c+2)

You can break the functions into components as given below:

d=b+c

e=c+2

a=d*e

Session

A session can implement the operation from the graph. To stuff the graph with values of a tensor, we are required to open a session. Within a session, we must run an operator to form a result. 

Why Is TensorFlow Famous?

This data analytics framework is the better library for all as it is easily accessible to all. TensorFlow library accommodates varied API to formulate a scale deep learning frameworks such as Convolutional Neural Network (CNN) or Recurrent Neural Network (RNN). 

This framework is based on graph computation as it can enable the developer to formulate the creation of the neural network along with Tensorboard. His tools enable debugging the program. It operates on GPU or CPU.

Applications Or Use Cases Of TensorFlow

TensorFlow offers great operations and services when compared to other famous deep learning frameworks. TensorFlow is used to formulate a large-scale neural network with many layers.

It is primarily used for machine learning or deep learning issues such as Perception, Classification, Understanding, Discovering Predictions, and Creation.

Voice Or Sound Recognition

Sound and voice recognition applications are the most popular use cases of deep learning. If the neural networks have proper input data feed, neural networks are capable of evaluating audio signals. 

For Instance:

  • Voice Recognition is employed in the IoT (Internet of Things), security, automotive, and UI/UX. 
  • Sentiment Analysis is primarily used in customer relationship management (CRM). 
  • Flaw Detection (engine noise) is primarily used in Aviation and automotive. 
  • Voice Search is primarily used in customer relationship management (CRM).

Image Recognition

Image recognition is the first application that made machine learning and deep learning popular. Social Media, Telecom, and handset manufacturers, motion detection, image search, photo clustering, and machine vision. 

For instance, image recognition is used to identify and recognize objects and people in the form of images. This is used to evaluate the context and content of any image. 

In the case of object recognition, TensorFlow allows to classification and identify arbitrary objects within larger images. This is also availed in engineering applications to recognize shapes for the purpose of modeling and by Facebook for photo tagging.
