Here I go over Preprocessing, which is super important when you're working with data and want to do some transformations to it beforehand in order to use it to do machine learning.
I first start of with a brief explanation of simple preprocessing such as making an array of categories categorical, etc. The other type of super basic preprocessing that I go over is the normalization of data (which is something you always want to do).
We then go over sequence preprocessing and where I explain multiple preprocessing concepts and tools such as: “padding” of a sequence of actions; using skipgrams (incredibly useful if you’re doing any "one-hot vector" type stuff); natural language text preprocessing (including an overview of using the classic tokenizer).
Then, we move onto image preprocessing. Here I show you some cool ways to augment your image/data with random shifts and permutations like: image rotation, shifting width and length, sheering images, zooming, horizontal/vertical shift, rescaling, etc) after which I show you all of these image preprocessing techniques in action!
