Machine Learning - Skills

Machine Learning has a very large width and requires skills across several domains. The skills that you need to acquire for becoming an expert in Machine Learning are listed below −


  • Statistics

  • Probability Theories

  • Calculus

  • Optimization techniques

  • Visualization


Necessity of Various Skills of Machine Learning


To give you a brief idea of what skills you need to acquire, let us discuss some examples −


Mathematical Notation


Most of the machine learning algorithms are heavily based on mathematics. The level of mathematics that you need to know is probably just a beginner level. What is important is that you should be able to read the notation that mathematicians use in their equations. For example - if you are able to read the notation and comprehend what it means, you are ready for learning machine learning. If not, you may need to brush up your mathematics knowledge.

Probability Theory


Here is an example to test your current knowledge of probability theory: Classifying with conditional probabilities.


skills


With these definitions, we can define the Bayesian classification rule −


  • If P(c1|x, y) > P(c2|x, y) , the class is c1 .
  • If P(c1|x, y) < P(c2|x, y) , the class is c2 .

Optimization Problem


Here is an optimization function


skills


Subject to the following constraints −


skills


If you can read and understand the above, you are all set.


Visualization


In many cases, you will need to understand the various types of visualization plots to understand your data distribution and interpret the results of the algorithm’s output.


skills


Besides the above theoretical aspects of machine learning, you need good programming skills to code those algorithms.


So what does it take to implement ML? Let us look into this in the next chapter.
