Do you want to pursue a career in data science but been intimidated by the requirement of math? Data science must require maths skills like coding and analyzing. But maybe you overthink about math prerequisites. The amount of math in your work depends on your role or job requirements.
Let’s unfold what kind of math is necessary for data science industry.
Any data scientist must have a good command of mathematics skills. As an integral part of data science, mathematics makes a strong base for understanding data science concepts and ideas.
Why math skills are necessary:
Understanding machine learning algorithms, discovering insights from data and performing mathematical analysis skills provide a strong foundation. Understanding and identifying business challenges and converting them into mathematical order is essential for data science’s workflow.
Mathematical skills leverage many data science job positions such as business intelligence developer, machine learning engineer, data architect, and industry specialist.
Let’s check what kind of math skill requires for data science.
Linear Algebra is necessary to build linear equations while developing machine learning algorithms. These are necessary to examine data sets. Linear Algebra is a critical component of machine learning because it is used in regularization, covariance metrics, loss function and support vector machine classification.
Linear Algebra is required to perform many calculation functions efficiently. When performing principal component Analysis to less the dimension of data, linear Algebra helps a lot. When working with neural networks, the processing and representation of networks can be simplified with linear Algebra.
Hence linear Algebra plays an essential calculation process for many models. At the same time, it is unusual that you handwrite code to apply transformations to matrices while use existing models to specific data set. Thus, understanding the principle is essential, but you don’t need to be a pro in linear Algebra to model problems.
Many data science elements depend on calculus but don’t worry. You don’t need to learn more than you expect. If you had a traumatic past with calculus from high school, you might need to re-learn basic calculus to get into data science industry.
While practicing algorithms, you need to use Multivariate calculus for gradient descent. You must have the knowledge or good command of quadratic and curvature, derivatives, divergence and approximations.
For some data scientist roles, it’s necessary to understand calculus principles and how they affect models.
Statistics is necessary for machine learning. It is used for testing the efficiency of a marketing campaign, such as hypothesis testing. Statistic requires when working with classifications such as discrimination analysis, logistic regression and hypothesis testing and distributions.
Statistics help understand customer behavior, for example, why users continuously follow a specific brand or buy a particular product. It is also required to design a survey or casual effect analysis, or personalized recommendations.
Probability is for hypothesis testing and distribution. Unfortunately, you have to some good knowledge about probability and statistics. And if you already have a strong background in these domains, you don’t need to worry. For a novice or beginner student learning probability and statistics take a big chunk of time.
Popular applications of mathematics in data science:
Organizations and companies need data scientists to power business value. Understanding how mathematics is used in data science can help you understand why companies need professional data scientists and how math is necessary for different functions and processes.
For image processing and image representation, use of Linear algebra is essential. When we talked about computer vision, companies like Tesla producing self-driving cars. Computer vision is also used in healthcare to diagnose illness and improve diagnosis.
Natural Language Processing (NLP)
Linear algebra is also used in NLP for embedding words, learning techniques and predictive analysis. Good examples of NLP are chatbots, speech recognition, language translation and sentiments analysis.
In a nutshell:
Having mathematical skills, predominantly linear algebra, statistics, and calculus provides data scientists a solid foundation for carrying along with the job. Fortunately, if you have a background in mathematics, it’s easy for you to understand various data science processes. Moreover, implementing different math skills is a crucial part of a data scientist’s job.
