There are 3 parts
First part, it's a PCA implementation
Second part, its a word2vec implementation
Third part, it's a dimension fuess game(?)
About the thrid problems, there's description below:
In this assignment, you have to predict the intrinsic dimension of the given sets of data points. Each set contains 10k ~ 100k data points. The data points were sampled from a Standard Normal Distribution in the intrinsic dimension (that corresponds to the particular set) and then are embedded into a higher dimension via a 3-layer neural network, with ELU activation in the first two layers and linear activation in the last layer. There are 200 sets in total.
