Those are the notes I made during the whole course, it is not a summary! As long as you understand this document you do not need to watch any lecture. With those notes I have passed the course with a 7.5.

Lecture 1
Introduction
Foundations of Deep Learning

Probabilistic Learning

e.g. Toss a coin




Bernoulli distribution




Deep Learning 1

, likelihood function in this case: product, because independent and identical from same coin, one probability




Objective function: .. all identically distributed so all follow Bernoulli




finding best x:




formulating it as general approach, probabilistic learning (likelihood-based) —> always done like this
p(y|x) is probability distribution



Deep Learning 2

, probabilistic values bernoulli can be used, real or continues values can be done with gaussian or
others

identically and independently —> iid, else if sequential you are dependent of past so a method with
sequential (generative regressive models, rnn)

Logistic Regression

= model that allows us to classify objects
linear dependency: when the result of coin depends on the hand velocity while coining, or the mail calling
spam depends on the words. Its probabilistic so we need sigmoid




Deep Learning 3

, gradient = vector of derivatives




note for image: derivative with respect to theta applying the chain rule

we get the difference between our prediction (sigmoid, y?) and the label x which comes into the gradient. If
our model is correct, the weights θ will not change, else we will follow the direction of x (-1)
