Sir, at time 17:35 in the video how do we arrive at the relation between "\theta" (model parameters) and function h?
Yes, thats right! :)
So, in other words, we are explicitly designing our hypothesis function so that it satisfies the stated condition.
Is Theta0 the first entry in the vector Theta. As in Theta=( Theta0, Theta1,...)?
That depends on how theta and the input vector are defined. If theta_0 is included in theta vector, then the input vector needs to be augmented with a unit element (value=1). Its just a matter of convention, but one has to be careful while implementing the code from scratch.
Sir, are there any advantages of expressing probability as log odds or log odds of hypothesis being a linear function?
Certainly yes! Firstly, linear functions are easier to interpret. Secondly, linear functions and their gradients are easier to compute.
