The 21st century is all about the internet. It is the digital age. The technology of Computer Science has created an astounding revolution and has created an irreversible impact on human lives. We are witnessing the technological revolution every single day of our lives. The Internet is ruling the world. From Agriculture to Aeronautics, every industry has been turned upside down by Computer Science and Engineering. There is a lot of demand for M.Tech in Computer Science and Engineering.
However, technology is ever updating and people who work in the industry of Computer Science and Engineering must also update themselves with the latest tools and technologies. Hence, pursuing an M.Tech in Computer Science and Technology in the most in-demand domains like Data Science and Engineering would be a great career choice to make.
Why Data Science and Machine Learning
Data Science these days is recognized as one of the most heard terms. Data Science indeed is a buzz word and it has gained huge demand in recent times. Many are aspiring to learn this exciting technology and the demand for the Masters in Data Science domain is rising high.
What is Data Science
Before we understand what Data Science is, let's understand it's the origin. In the past businesses and other institutions which dealt with data we're able to store most of the data in excel sheets. Simple business intelligence tools were capable of analyzing and processing this data. The major reason behind this was the availability of a lesser amount of data. As time passed by, the amount of data available to be analyzed kept increasing rapidly. We live in the era of the internet, everything we do on the internet is generating data. However, most of the data being available will be either semi-structured or unstructured. In order to process data of this magnitude, we do need extremely sophisticated and advanced tools and technologies. This is why Data Science has come into the picture. The technology of Data Science deep dives at a granular level of data to mine and understand the complex behaviors and trends of Data.
The technology of Data Science can bring out hidden insights that can help entitles to make smarter business decisions. Netflix employs data science to mine data related to viewing patterns of its consumers and understand what drives user interest, based on the findings, it produces original series. P&G utilizes time series models to more clearly understand the future demand which helps to plan for production levels more optimally.
Machine Learning is an important subset of the broader term Artificial Intelligence which is an in demand technology.
The idea behind Machine Learning is that you teach machines by feeding them data and letting them learn on their own without any human interventions. The process of learning begins with observations or data such as examples, direct experience, or instruction in order to look for patterns in data and make better decisions in the future considering the examples that we provide. The primary goal here is to allow computers to learn automatically from the data without human intervention or assistance and adjust actions accordingly.
Data science conveys a wide spectrum of domains and machine learning is one among them. Apart from Machine Learning, technologies of Artificial Intelligence and Deep Learning also fall under the domain of Data Science. Deep learning is a subset of Machine Learning. Hence, Artificial Intelligence, Machine Learning and Deep Learning are all used in Data Science for the analysis of data and extraction of meaningful insights out of it.
Let us understand how Machine Learning is used in Data Science.
Before we understand how Machine Learning is used in Data Science, it is essential to understand the Data Lifecycle and understand the stage at which Machine Learning is employed. Are Data Science and Machine Learning the same? What is the difference between Data Science and Machine Learning?
Let's say you are aspiring to design a recommendation system for your e commerce website, this system recommends products to the customers on the basis of their shopping patterns. In order to build such a recommendation system, you may use the data related to the customer's browsing history, previous purchases, their reviews, ratings, profile details, card details and more. During the development process, you will have to go through the different stages of Data Science.
Below are the various steps involved in the lifecycle of Data Science
1. Business Requirements
The first phase of Data Science is understanding the problem you are trying to solve. Hence, you will have to list the business requirements accordingly. Gathering the required data from different resources is a crucial part of the whole Data Science process.
2. Data Acquisition
In the Data Acquisition stage, you will identify the various resources from which the data will be acquired to solve the given business problem. If you are trying to build a recommendation system, gathering user ratings, comments, chat history, and more would be a few resources of data gathering.
3. Data Processing
Once you gather all the data that is required for solving the given problem, you enter the Data processing and cleaning phase of the data science process. In this phase, the raw data that is collected will be transformed into the desired format so that it facilitates you to perform the desired operations on it.
4. Data Exploration
Once you are one with the Data Processing phase, you will enter the Data Exploration stage where a data analyst employs visual exploration to understand what is in a data set and the characteristics of the data. These characteristics can include size or amount of data, completeness, the correctness of the data, possible relationships amongst data elements, and more.
5. Data Modelling
The fifth stage of Data Science is Data Modelling where you incorporate Machine Learning in Data Science. This is where you need Machine Learning. Let us understand how Machine Learning is implemented in the Data Modelling stage. The data gathered in the earlier stages is imported in the process. This data should be in a proper structure. A table or CSV formats are a few of the preferred formats. After this, the data is further cleaned in order to get rid of any inconsistencies. Then the data model is built where the data is split into two sets, one for training and the other for testing. This model is built by the training dataset. This is where the data analyst employs several Machine Learning algorithms. A training dataset is used to train the model. Once the model is trained it is then evaluated by using the data set. In this phase, the model is fed with new data points and it must predict the outcome by running on the new data points on the Machine Learning model that was built earlier. After the model is evaluated using the resting data, its accuracy is calculated. The accuracy is then improved by various different methods. Hence, this is how Machine learning is employed in the lifecycle of Data Science.
6. Data Optimization
After the completion of the Machine Learning stage, the final model is deployed onto a production environment for final user acceptance.
This is how Data Science and Machine Learning go hand in hand.
