For feature selection: is having no individual prediction power (in your example, eyes) enough to tell whether those features have no value at all? Could they not have some non-linear joint predictive power with some other features?

*quick summary of the video:* - let's say that your goal is develop a program that can distinguish between two breeds of dogs - what features do you want your example data to have? - you want the features to be the "distinguishing" features between the breeds, i.e. features that are very different between the two dog breeds - for example, if the two dog breeds tend to have very different heights, you want to use height as a feature in your training data - if on the other hand, the two dogs have about the same distribution of eye colors, you don't want to use eye color as a feature - you also don't want to use features that are highly correlated (i.e. that don't bring in new information) - you want to use simple features, as simple features will require less examples to get a decent classifier - you wanna be careful about adding too many features, especially if the features are not "distinguishing" features, they may just by chance be distinguishing in your example data, thus your classifier will start basing its predictions based on these faulty features *key thing to take away from the video:* Selecting features is extremely important. Select the simple, distinguishing features, that bring in new information (i.e. that aren't highly correlated). Thanks so much for these videos!

How do you use categorycal features, for example, we are trying to train a classifier and one of the features is "State"(or maybe "city"), do you create a mapping table where every state(or city) gets a numerical representation? Or would you solve this at programming level: looping through the states(or cities) and finding a classifier for every state(or city) ?

simplified classifiers OK. what if feature ratio's are significant or their are sorting stations for the letters with varied release times for the letters... eh just confusing things. will the ML program figure out relationships between features if it is supervised or is it our job to figure out the relationships. Actually isn't the problem that if we have a system with 2500 features and do not know how they are significant then ml will figure it out?
