Hello everybody,

we hope you are all doing fine. What comes here is our weekly summary with plans for this week's lectures and lab.

The lab session is pretty obvious, we keep working on project 1.

Last week we discussed logistic regression and gradient methods, and started to look at stochastic gradient descent and its family of methods.

Although it does not sound like a very exciting topic (and far away from all the interesting data we can analyze with ML methods), finding the minima of the cost/risk function is the true bottleneck of all machine learning methods. For our 'simpler' methods linear regression and logistic regression, we end up with clear convex functions and the search for an optimal minimum is facilitated by that.&nbsp...
