Third assignment: the challenge
The third project is organized in the form of a challenge, where you will compete against each other. This year, the challenge is about speech recognition. More precisely, you will have to develop a model which can recognize digits from 0 to 9 as well as nondigits. All the relevant information can be found on the Kaggle plateform which will hold the challenge.
The project is divided into four parts. All the deadlines can be found in the schedule section above.

Setup for the project
 Create an account on the Kaggle plateform. Use your real name so that we can identify you.
 Form groups of two (or three)
 Test the toy example
 Propose the best model you can
 Submit an archive on the submission platform in
tar.gz
format, containing a report that describes the different steps of your approach and your main results along with your source code. Use the same ids as for the Kaggle plateform. The report must contain the following information: A detailed description of all the approaches that you have used to win the challenge, including the feature engineering you performed. The kaggle winning model guideline should be followed for each approach (you can disregard the background info, just specify your section).
 A detailed description of your hyperparameters optimization approach and your model validation technique.
 A table summarizing the performance of your differents approaches containing for each approach at least the name of the approach, the validation score, the score on the public and the private leaderboard.
 Any complementary information or figures that you want to mention.
 Present succinctly your approach to the rest of the class. (More information coming soon)
Have fun!

Supplementary material
Here is a very scarce list of supplementary material related to the field of machine learning. I tend to update this section when I come across interesting stuff but if you feel like you need more material on some topic, do not hesitate to ask!
Machine learning in general
There are tons of online and accessible material in the domain of machine learning: Andrew Ng's online course (Standford): The most popular online course on ML. Archived from coursera.
 Pedro Domingos' online course (Washington).
 Reza Shadmehr (Baltimore) and his slides.
 Jeffrey Ullman's course on mining massive datasets (Standford) based on his reference book. Not everything is related to the course though.
Linear regression
The geometry of Least Squares (1 variable)
Note that the ANOVA is a special case of linear models where the input variables are dummy onehot class variables. Consequently, the basis vector of the column space are orthogonal and the problem reduces to many 1 variable least squares.Artifical neural networks
There have been three hypes about ANN. The first one was about the perceptrons in the 60s until it was discovered it could not solve a XOR problem. The second hype started with the discovery of backpropagation but it soon became clear that the large and/or deep neural nets were very hard to train. We are in the midts of the third one right now with "deep learning": neural nets with several (many) invisible layers. As a consequence, internet is bursting with resource on the topic, from the simplest models (multilayer perceptron) to the most advanced architectures (such as GANs), going through more classical ones (such as Convnets and LSTM).

Prerequisites
Machine learning requires a solid background in maths, especially in linear algebra, (advanced) probability theory and (multivariable) calculus. There are even more resources on those than on deep learning. Here is a short selection, which emphasizes intuition.
Linear algebra

Calculus
