5. Modify the EM implementation (see the notebook file EM algorithm.ipynb shared with you on the google drive) to allow for three classes (each following a Gaussian distribution with different mean and standard deviation) in the data. You should modify the code to generate three classes of the data and use the EM algorithm to learn the parameters for the three Gaussian distribution. You should submit your modified implementation in a notebook file through canvas, which should include the implementation as well as a short description of your simulation result
