Prerequisites for Machine LearningNowadays, machine learning has become one of the most sought-after technologies of the era, and undoubtedly it is the wave of the future. If you are interested in learning machine learning, then you must be aware of the prerequisites for machine learning. The machine learning prerequisites will help you to make a better career path. ![]() Machine Learning is an interdisciplinary field of mathematics and computer science that aims to teach machines to perform cognitive activity similar to humans. In machine learning, the term learning specifies a way by which machines take input data, examine or analyze data, and gain insights from it. Machine learning systems use different algorithms to automatically learn patterns from datasets that may include structured data, numeric data, textual data, visual data, etc. In order to succeed in machine learning technology, it is very important to understand each concept in a proper way. In this topic, we will discuss the perquisites for machine learning so that you can make your base better for learning its advanced concepts. What are the prerequisites for machine learning?To get started with machine learning, you must be aware of the below points.
Educational Prerequisites for machine learningDoes Master's/Ph.D. require to become a Machine learning engineer? This is one of the most common questions regarding educational qualification for ML among the aspirants who want to learn Machine learning and make a career in this. The answer for this is NO, it means, it is not necessary that you must have a master's or Ph.D. degree to learn and make a career in machine learning. There are lots of people who have made a career in this field without having a degree. However, having a Ph.D. or Master's degree will definitely give you additional benefits and will make the path smoother. The master's/Ph.D. certificate works as a way to showcase your skills, but in the end, your practical knowledge & skills will help you to either build a project or make a career in Machine learning. So, if you have enough time and funds to have a Master's or Ph.D. degree, you can do this, and it will surely give you benefit. But if you are not having a degree and have good ML skills, then also you can make the transition into Machine learning. Skill-based Prerequisites for Machine learning Career 1. StatisticsMachine learning and statistics are the two tightly coupled fields, as most of the concepts of machine learning are either taken from statistics or are dependent on it. Machine learning techniques and algorithms are widely dependent on statistical concepts and theories; hence it is a crucial prerequisite for ML. Statistics is a field of mathematics that allows to draw the logical conclusion from the data. Every machine learning enthusiast must understand the statistical concepts in order to learn the working of algorithms such as logistic Regression, distribution, hypothesis testing, etc. It helps in performing the following task:
Some fundamental concepts of Statistics needed for ML are given below:
2. Linear AlgebraLinear algebra deals with the study of vectors & some rules of manipulating these vectors, matrices, and linear transform. It is one of the integral parts of machine learning and helps the ML algorithms to run on a huge number of datasets with multi-dimensionality. The concepts of linear algebra are widely used in developing algorithms in machine learning. It can perform the following task:
Although linear algebra is one of the crucial prerequisites for machine learning, it is not required to go in-depth in this, at least not for the beginner; only understanding of the basic concept is enough to start. 3. ProbabilityIn the real world, there are various scenarios where the behavior or output can vary for the same input. Probability has always been an essential part of Mathematics, which measures the uncertainty of the event. The higher the probability of an event, the more chances that event will occur. In Machine learning, probability helps to make predictions with incomplete information. It helps in predicting the likelihood of future events. With the help of probability, we can model elements of uncertainty such as risk in a business process or transaction, i.e., we can work with non-deterministic problems. Whereas in traditional programming, we deal with deterministic problems; output is not affected by uncertainty. It also helps in hypothesis testing and distributions such as Gaussian distribution and Probability density function. Probability theory and statistics are related fields; probability deals with future events, whereas statistics deal with the analysis of past events. Below are some commonly used Probability concepts:
4. CalculusCalculus is also an integral part of Machine learning, but it is not required to go in-depth of it at the beginner level; rather, only knowledge of basic concepts is enough. In machine learning, the process of getting the best parameters is known as optimization, and multivariate calculus helps in solving optimization problems in the ML model. It helps in optimization and getting good results from the model. In calculus, we don't need to solve complex derivatives manually; rather, we must understand how differentiation work and how it is applied for vector calculus. Multivariate calculus is not only used for algorithm training but also for gradient descent. Some crucial concepts of multivariate calculus are Derivatives, divergence, curvature, and quadratic approximations, Laplacian and Lagrangian Distribution, Directional Gradient, etc. 5. Programming LanguagesApart from the mathematical concepts, it is very important to have a good knowledge of a programming language and coding capabilities for machine learning. Some of the most popular programming languages for machine learning are as follows: PythonPython is the most powerful and easy language that anyone can learn. Python was initially developed in early 1991. Most of the developers and programmers choose Python as their favorite programming language for developing Machine learning & AI solutions. The best part about Python is it is very easy to learn compare to other programming languages and also offers great carrier opportunities for programmers and data scientists. Python provides excellent community support and an extensive set of libraries, along with the flexibility of programming languages. Python is a platform-independent language as well as it provides an extensive framework for Deep Learning and Machine Learning. Python is also a very portable language as it can be used on different platforms including Linux, Windows, Mac OS, and UNIX. RR is one of the great languages for statistical processing in programming. It may not be the perfect language for machine learning, but it provides great performance while dealing with large numbers. Some inbuilt features such as built-in functional programming, object-oriented nature, and vectorial computation make it a worthwhile programming language for machine learning. R contains several packages that are specially designed for ML, which are:
Java:Java is the most widely used programming language by all developers and programmers in the world. Java can be easily implemented on the various platform due to JVM(Java Virtual Machine). The best things about Java is once it is written and compiled on one platform, then you should not need to compile it again and again. This is known as WORA (Once Written Read/Run Anywhere) principle. Java has so many features which make Java best for use in Machine learning. These are as follows:
Selecting the correct Programming LanguageApart from the above-mentioned programming languages, there are many other programming languages that are being used in Machine learning, such as C, C++, MATLAB, JavaScript, etc. However, choosing the best languages may become a challenging task for beginners. In machine learning, Python and R are the two most preferred languages because of their great benefits and vast libraries. However, other general-purpose languages can also be used, such as Java, C, C++, but make sure you are skilled with these languages. Apart from the above programming and mathematics skills, awareness of some basic concepts of machine learning is required to learn advanced concepts. These concepts include machine learning types (Supervised, unsupervised, Reinforcement learning), techniques, model building, etc.
