Data science cannot exist without the application of mathematics. A solid foundation in a variety of mathematical subfields is required of all data scientists, whether they are actively engaged in the field or simply considering pursuing it as a potential career path.
Mathematical training is necessary for a job in data science because the development of machine learning algorithms, the execution of analyses, and the extraction of insights from data all require math. Even if mathematics will not be the sole prerequisite for your educational and professional route in data science, it will likely be one of the most crucial requirements. It is generally agreed that one of the most significant steps in the process that a data scientist goes through is figuring out the business problems that need to be solved and then converting those problems into mathematical ones.
In today’s article we will discuss subsets of mathematics that are constantly being leveraged in data science and applications of mathematics in Data science, then we decide if Math is required for Data Science or not. Let’s get started.
Various mathematical specializations that are put to use in the field of data science
The following is a list of some of the most prevalent forms of mathematics that you will encounter throughout your work as a data scientist.
- Linear Algebra
Understanding how to construct linear equations is a fundamental skill necessary for the creation of machine learning algorithms. These are the tools that you will use to investigate and analyze data sets. In the field of machine learning, linear algebra is utilized in a variety of areas, including loss functions, regularization, covariance matrices, and support vector machine classification.
Calculus of multivariable is applied in gradient descent and the process of algorithm training. Derivatives, curvature, divergence, and quadratic approximations are some of the topics that you will learn. It is absolutely necessary to have a solid understanding of elementary calculus in order to work with intermediate data science techniques. Differentiation, integration, and multivariate calculus are some of the topics covered in this domain. When you start working with more complex algorithms, having some familiarity with stochastic calculus will come in very handy.
When working with classifications in machine learning, such as logistic regression and discrimination analysis—as well as hypothesis testing and distributions, this is a necessary step. Every company is making efforts to transform themselves into a data-driven organisation. Because of this, there has been a significant uptick in the demand for data scientists and analysts in recent years. Now that we have the data, we need to make sense of it so that we can solve problems, answer questions, and devise a strategy. The good news is that statistics provides a collection of tools that can be used to obtain those insights.
This is an extremely important factor to consider when testing hypotheses and calculating distributions like the Gaussian distribution and the probability density function.
After going over the different categories in mathematics and data science, the next step is to investigate the applications.
Mathematics' Most Commonly Employed Applications in Data Science
On a day-to-day basis, companies operating in any sector require the assistance of data scientists to function properly and achieve their goals. If you have an understanding of how mathematics may be applied in real-world situations, you will have a better understanding of why organizations want data scientists and how mathematics comes into play.
Let's have a look at some of the real-world applications of mathematics in some of the most popular applications and technologies in the fields of data science and machine learning that are being used by the most successful companies today:
- The processing of natural languages (NLP)
Word embeddings and unsupervised learning approaches like topic modeling and predictive analytics both make use of linear algebra in natural language processing (NLP). Chatbots, language translation, speech recognition, and the study of sentiment are all examples of applications for natural language processing.
- Computer Vision
The field of computer vision, which includes image representation and image processing, is another application of linear algebra. People often think of firms like Tesla when they consider computer vision because of the self-driving automobiles that they produce. Computer vision is also utilized often in a variety of other areas, such as agriculture and healthcare, with the goals of increasing crop yields and improving diagnostic accuracy respectively.
- Marketing and Sales
Testing the viability of marketing efforts, also known as hypothesis testing, is made easier with the help of statistics. It is also used to study customer behavior, such as why people are purchasing from a specific brand, through the use of techniques such as causal impact analysis or survey design, as well as personalized recommendations through the use of predictive modeling or clustering.
We have reached the end of the article, but are yet to answer the questions: Is Math Required for Data Science? A big fat “YES”. The essence of Math can never be summarized in an article or covered in a video. It is important not only in the world of data science but also in real life. Without mathematics, calculations and inventions would be near impossible to happen. To summarize what we have discussed, we understood about the various subsets of mathematics and its application in the data science domain. We witnessed that it is not possible to understand data science without including math in it.
