In the past two years, I have been exposed to the basics of statistics and mathematical concepts that go on to lay the foundation of the complex AI machinery we see in the form of Alexa, Jarvis, Siri, etc. I feel some of these concepts are so much easier to visualize in real life. These things are pretty clear intuitively if we think about them practically based on what we experience in the world. The concept of Markov Chains -- "The future is conditionally independent of the past given the present". At any point in our life, we can only control our present and our present is reflective of the entire past i.e. the knowledge and experiences from our past define our present condition and our future progress is solely dependent on what we are today and how much effort we put into transition to a more desirable state in the future.
