Data Science Roadmap: An Overview

How to Become a Data Scientist?

In the world of data space, the era of big data began when companies began handling petabytes and exabytes of data.By 2010, it had become very difficult for the industry to store data.Now, once the storage problem is solved by popular frameworks like Hadoop, the focus shifts to processing the data.Data science plays a big role here.Data science is growing in many ways today, and you should prepare for the future by learning what data science is and how it can add value.

However, if you are more curious about How to become a data scientist or How to begin your career as a data scientist consider learning this article: How to become a data scientist?

What is a data science?

So the first question that arises is, “What is data science?” Data science means different things to different people, but at its core, data science is about using data to answer questions.This definition is reasonably broad because it must be said that data science is a reasonably broad field.

Data science is the science of using statistics and machine learning techniques to analyze raw data and draw conclusions from that information.So we can say that data science includes: Statistics, Computer Science, and Mathematics Data Cleaning and Formatting Data Visualization By now, we all know how popular data science is.

This raises the following questions:

  • Why do data science (set your goals in the first place)
  • how do you get started? Where do you start?
  • What topics should I cover?

How to Learn Data Science?

Data scientists typically have a variety of educational and professional experiences, and most are or should ideally be skilled in four main areas:

  • Domain Knowledge
  • Mathematical Skills
  • Computer Science
  • Communication Skills

Domain Knowledge :

Most people think that domain knowledge is not important in data science, but it is very important.Let me give you an example, If you want to become a data scientist in the banking sector and have more information about the banking sector such as stock trading and finance, it will be very beneficial for you. The banks themselves will have more preference.This type of applicant has an advantage over regular applicants.

Mathematics Skills:

Linear algebra, multivariable calculus, and optimization techniques are three very important as they help you understand the various machine learning algorithms that play an important role in data science.Similarly, understanding statistics is very important as it is part of data analysis.Probability is also important in statistics and is considered a prerequisite for mastering machine learning.

Computer Science:

There's still a lot to learn in computer science.But one big question arises when it comes to programming languages.Python or R for Data Science?There are many reasons to choose a language for data science.Both languages ​​have a rich set of libraries for implementing complex algorithms for machine learning, visualization, and data cleaning.For more information, see R and Python in Data Science.However, my recommendation is that you need to know both programming languages ​​to be successful as a data scientist.

What is a Data Science Roadmap?

The easiest way to answer this question is to first define the term "roadmap." A roadmap is a strategic plan that establishes a goal or desired outcome and includes the important steps or milestones needed to achieve that goal.Meanwhile, according to this article, data science is: Data science is a combination of statistics, mathematics, programming, and problem-solving.Capture data in a sophisticated way.The ability to see things differently.

Therefore, a data science roadmap is a visual representation of a strategic plan designed to help aspiring IT professionals learn about and succeed in the field of data science.Now, Let’s take a close look at this roadmap for data science

A Roadmap to Learn:

1. Mathematics:

In Data Science Math skills are very crucial as they help us in understanding various machine learning algorithms. You have to learn some basic concepts of math for it.

Section 1:

  • Linear Algebra
  • Analytic Geometry
  • Matrix
  • Vector Calculus
  • Optimization

Section 2:

  • Regression
  • Dimensionality Reduction
  • Density Estimation
  • Classification

2. Probability:

It is also significant to statistics, and it is considered a prerequisite for mastering machine learning.

  • Introduction to Probability
  • 1D Random Variable
  • The function of One Random Variable
  • Joint Probability Distribution
  • Discrete Distribution
  • Continuous Distribution
  • Normal Distribution (Python | R)

3. Statistics

Understanding Statistics is very important as this is a part of Data analysis:

  • Introduction to Statistics
  • Data Description
