Popular job roles in AI, ML and Data Science

  • Business Analyst
  • Product Analyst
  • Data Analyst
  • ML Engineer
  • Data Scientist
  • AI Scientist

Without a basic introduction to its fundamentals, machine learning can seem overwhelming. 

To master machine learning, you don’t have to be an expert programmer or mathematician, but you do need to possess fundamental knowledge in those fields.

Python for AI, ML and Data Science

You should prefer Python programming language for machine learning.

Data science, as you can see, focuses on problem-solving, exploration, and the extraction of useful information from data. 

You will need to manage datasets, train machine learning models, display the outcomes, and do a lot more in order to do this successfully.

  • Start by learning core programming concepts.
  • Next, gain a working knowledge of essential data science libraries.
  • Finally, you’ll practice and refine your skills through actual projects.

This approach will allow you to build mastery over time while having more fun.

Python Skill Kit:

  • Python Programming
  • Python Data structure: Lists, Tuples, Sets, Dictionary, Strings
  • Python ML libraries: scikit-learn
  • Python Data libraries: Pandas, Numpy, Scipy
  • Python Visualization: Matplotlib, Seaborn
  • Python Deep Learning: Tensorflow, Keras
  • Python NLP: NLTK, gensim, Textblob, etc.

Why “Python”?

  • The language of choice for most machine learning engineers and data scientists.
  • Most tools for data have been built in Python or have built API access for easy Python access.
  • Python’s syntax is relatively easy to pick up.

For example:

“hello, world!” in JAVA:

“hello, world!” in python:

  • Python is easy to learn and use. It can perform complex tasks using a few lines of code.
  • It is an interpreted language; it means the Python program is executed one line at a time. The advantage of being interpreted language, it makes debugging easy and portable.
  • Python can run equally on different platforms such as Windows, Linux, UNIX, and Macintosh, etc.
  • Python is freely available to everyone.
  • Python supports object-oriented language and concepts of classes and objects come into existence.
  • Also, other languages such as C/C++ can be used to compile the code and thus it can be used further in our Python code. It converts the program into byte code, and any platform can use that byte code.

It provides a vast range of libraries for various fields such as machine learning, web development, and also for scripting.

It can be easily integrated with languages like C, C++, JAVA, etc. Python runs code line by line like C, C++ Java. It makes it easy to debug the code.

The code of the other programming language can use in the Python source code. We can use Python source code in another programming language as well. It can embed other languages into our code.

Dynamic Memory Allocation: In Python, we don’t need to specify the data type of the variable. When we assign some value to the variable, it automatically allocates the memory to the variable at run time. Suppose we are assigned an integer value 15 to x, then we don’t need to write int x = 15. Just write x = 15.

Statistics for AI, ML and Data Science

Understanding statistics, especially Bayesian probability, is essential for many machine learning algorithms. Wikipedia defines it as the study of the collection, analysis, interpretation, presentation, and organization of data. Therefore, it shouldn’t be a surprise that data scientists need to know statistics.

Key concepts include probability distributions, statistical significance, hypothesis testing, regression, conditional probability, priors and posteriors, and maximum likelihood. If those terms sound like mumbo jumbo to you, don’t worry. This will all make sense once you roll up your sleeves and start learning. Furthermore, machine learning requires understanding Bayesian thinking. 

Bayesian thinking is the process of updating beliefs as additional data is collected, and it’s the engine behind many machine learning models.

Math for AI, ML and Data Science

Original algorithm research requires a foundation in linear algebra and multivariable calculus.

Do you need to have a math Ph.D to become a data scientist? 

Absolutely not! 

How much math you’ll do on a daily basis as a data scientist varies a lot depending on your role. 

First, every data scientist needs to know some statistics and probability theory.

How much maths?

You won’t have to conduct complex mathematical calculations, especially in entry-level positions, because there are powerful math libraries already included. 

There is no need to start from scratch. But, your knowledge of multivariable calculus and basic linear algebra may still be tested in interviews.

R&D-Heavy Machine Learning Positions need much more original ML research and development. 

You may need to translate algorithms from academic papers into working code. Or, you might research enhancements based on your business’s unique challenges.

In other words, you’ll be implementing algorithms from scratch much more often. For these positions, mastery of both linear algebra and multivariable calculus is a must. You’ll use linear algebra to represent the network and calculus to optimize it.

Mathematics for AI:

  • Statistics
  • Probability
  • Linear Algebra
  • Calculus

Other necessary tools:

  • SQL / Spark / Hive: for extracting data
  • AWS / GCP/Azure: for deploying data solutions
  • Learn to use collaborative tools such as Github.

Also, get into the habit of writing your code using jupyter notebook.

  • Jupyter Notebook is a very popular and flexible tool that lets us put our code, the output of the code, and any kind of visualization or plot, etc. in the same document.
  • We use the Jupyter Notebook since it comes pre-installed with most of the important data science libraries you’ll use. 
  • It comes with an easy, clean interactive interface that allows you to edit your code on the fly.
