How to Start Learning Machine Learning?

In 1959, Arthur Samuel invented the phrase “Machine Learning,” which he characterized as a “field of study that allows computers to learn without having to be explicitly programmed.”

However, there is still a lot of confusion about what Learning Machine is and how to get started learning it. So, in this article, we’ll go over the fundamentals of machine learning as well as the steps you may take to become a full-fledged Machine Learning Engineer. Let’s get this party started!.

What is Machine Learning?

Machine Learning is the application of Artificial Intelligence to allow computers to learn a task via experience rather than being programmed expressly for that activity. (In other words, machines learn without human intervention!!!) This procedure begins with providing them with high-quality data, which is then used to train the machines by creating multiple learning machine models based on the data and various methods. The algorithms we use are determined by the type of data we have and the task we are attempting to automate.

How to start learning Machine Learning?

This is a rough outline of what you’ll need to do to become a world-class Engineer Learning Machine. Of course, you can adjust the stages to meet your own needs in order to achieve your desired end result!

Step 1: Recognize the Prerequisites

If you’re a genius, you can get right into ML, but you’ll need to grasp the basics first, such as linear algebra, multivariate calculus, statistics, and Python. And don’t worry if you don’t recognize them! To get started, you don’t need a Ph.D. in these subjects, but you do need a fundamental understanding.

a) Understand linear algebra and multivariable calculus.

Machine Learning requires both Linear Algebra and Multivariate Calculus. The amount to which you require them, though, is determined by your function as a data scientist. If you’re more interested in application-driven machine learning, you won’t be as concerned with math’s because there are numerous common libraries available. However, if you want to specialize on Machine Learning research and development, you’ll need to know Linear Algebra and Multivariate Calculus because you’ll have to create several ML algorithms from scratch.

  1. b) Acquire statistical knowledge

In Machine Learning, data plays a vital role. In reality, collecting and cleaning data will take up roughly 80% of your time as an ML specialist. Statistics, on the other hand, is a discipline that deals with data gathering, analysis, and presentation. As a result, it should come as no surprise that you should learn it!!!

Statistical Significance, Probability Distributions, Hypothesis Testing, and Regression are some of the basic ideas in statistics that are crucial. Bayesian Thinking, which deals with topics such as Conditional Probability, Priors and Posteriors, Maximum Likelihood, and so on, is also an important aspect of machine learning.

  1. c) Study Python

Some students decide to forgo Linear Algebra, Multivariate Calculus, and Statistics in favor of learning them on their own through trial and error. But there is one thing you must not overlook: Python! While other languages such as R, Scala, and others can be used for Machine Learning, Python is the most popular. Python is now the most used ML language. Many Python libraries, such as Kera’s, TensorFlow, Scikit-learn, and others, are specifically useful for Artificial Intelligence and Machine Learning.

Step 2 – Learn Various Machine Learning Concepts

You can now continue on to really learning ML (which is the fun part!!!) once you’ve completed the prerequisites. It’s preferable to start with the fundamentals and work your way up from there. The following are some of the fundamental ideas in machine learning:

(a) Model Terminologies –

  1. A model is a specific representation learned from data through the use of a machine learning algorithm. A hypothesis is another name for a model.
  2. A feature is a measurable property of the data that is unique to it. A feature vector is an useful way to define a set of numeric features. The model is fed with feature vectors as input. Color, smell, and taste, for example, may be used to forecast the appearance of a fruit.
  3. A target variable, often known as a label, is the value that our model is supposed to predict. The label with each set of input in the fruit example stated in the feature section would be the name of the fruit, such as apple, orange, or banana.
  4. Training – The idea is to provide a collection of inputs (features) and predicted outputs (labels), such that after training, we will have a model (hypothesis) that will map incoming data to one of the trained categories.
  5. Prediction — Once our model is complete, we can feed it a set of inputs and get a predicted result (label).

(b) Types of Machine Learning

  1. Supervised Learning –

entails utilizing classification and regression models to learn from a training dataset with labelled data. This process of learning will continue until the requisite level of performance is met.

  1. Unsupervised Learning –

This entails taking unlabeled data and applying factor and cluster analysis models to uncover the underlying structure in order to learn more and more about the data.

  1. Semi-supervised –

Learning combines unlabeled data with a little quantity of labelled data, similar to Unsupervised Learning. Labeled data greatly improves learning accuracy while also being less expensive than Supervised Learning.

  1. Reinforcement Learning–

entails trial and error in order to learn the best actions. So learning behaviors that are based on the current state and that will maximize the reward in the future determines the next action.

(c) How to Practice ML?

  • Data collection, integration, cleaning, and preprocessing are the most time-consuming aspects of learning machine. So, make sure to practice because you’ll need high-quality data, and vast amounts of data are frequently unclean. So, this is where you’ll spend the majority of your time!!!
  • Learn diverse models and put them to the test on real-world data. This will aid you in developing intuition about the types of models that are acceptable in certain scenarios.
  • Along with these processes, it’s also crucial to know how to analyze the findings generated through the use of various models. This is made easier if you are familiar with the various tuning parameters and regularization methods used on various models.

Step 3 – Take part in Competitions

After you’ve mastered the fundamentals of learning machine , it’s time to move on to the fun part: competitions! These will essentially improve your ML skills by mixing your primarily theoretical knowledge with practical application.


Machine Learning from Disaster: With several tutorials available, the Titanic: Learning  Machine from Disaster challenge is a popular beginner project for ML. As a result, it’s an excellent primer on machine learning principles like data exploration, feature engineering, and model tuning.
