Data Science for beginners
Data Science is a trending technology and the Data Scientist job is considered the sexiest job of this modern era. As more attention is drawn towards, many aspirants want to learn Data Science and make a career in this field. But how to learn Data Science?. This article will give you an idea of how to start Information Science, it is a roadmap for beginners.
There are a plethora of resources available on the internet, but beginners might get perplexed with the abundant material available on the net and don’t have any idea how to start. This article will showcase the steps to learn Data Science Training in Pune.
What is Data Science?
It is the technology used to extract valuable insights from enormous amounts of data that is used to make data-driven decisions by businesses.
Prerequisites:
Learning Information Science is not a difficult task. If you have prior knowledge of Maths and Statistics, then it would be easy for you to start Data Science. All you need is time, extra effort, and practice. Here is a list of few topics that you have to learn to become proficient in Data Scientist.
Topics
Python
Python is a prominent and popular programming language across the world. It is considered a powerful tool for Data Scientist Course. Another language R is also very important. Python is easy to understand and it has varied applications. If you can learn the fundamentals of Python programming language, it would be quite beneficial to you.
Maths
Mathematics plays a very critical role in Data Science. However, you don’t need to be an expert in Maths, but basic knowledge is essential. When the data is analyzed using Python, the data is converted into matrix forms. So, if you have knowledge of these matrixes then it will be easy for you. You need to have basic knowledge of Calculus, Linear Algebra, Probability, and Statistics. These concepts you can learn from various online sites for free.
Python Libraries
There are various Python Libraries that are used to make complicated tasks of Data Science simple. If you are good at Python, then let’s know about Python Libraries.
Numpy
The first Python library that you have to learn is Numpy. It is a numerical library and does numerical operations. Numpy library is used to work with Linear Algebra. Linear Algebra is part of Maths that deals with Matrices.
Pandas
After you are equipped with Numpy, then start exploring Pandas. Pandas is a Python library that is used for quick data analysis, data pre-processing, and data cleaning. Pandas library helps to load and clean data sets and make data frames.
Matplotlib and Seaborn
The data is represented in graphical format with several charts and plots. This is known as Data Visualization. For this, Python provides two brilliant libraries called Matplotlib and Seaborn. Matplotlib is a comprehensive library used for creating static, animated, and interactive visualizations. It offers many inbuilt graphs and plots that make the process easy.
Seaborn works like Matplotlib and has various numerous capabilities.
Machine Learning algorithms
Machine Learning algorithms are helpful in analyzing and extracting valuable information. Machine learning is the scientific method that provides computer programs the ability to learn from previous experience and exhibit tasks.
There are numerous Machine Learning algorithms. No need to learn all of them, only a few which are important, you need to focus. They are Linear Regression, Logistic regression, Support Vector Machine (SVM), Random forests, Neural networks. K-nearest neighbors, etc. These algorithms can be easily executed by the Scikit-learn library. This library has many inbuilt programs that help Machine Learning algorithms to be implemented easily.

Python does have other libraries like Keras, TensorFlow for Deep Learning purposes.
It is a vast topic and has many subfields. If you want to learn in-depth about Data Science, then it is better for you to get trained at any reputed training institute that offers a Data Science Courses in Bangalore. If you can get Certifications, it will add value to your portfolio and helps you in grabbing high paid jobs in top-notch companies.
