Computer Exercise (Mandatory for Lab 3): Design a neural network to recognize an omnibot

You find an aptly-named notebook (Exercise_10.ipynb) on the jupyterhub servers (how to connect) under the latest version of frtn75-vision-sensor-and-ilc. Lab instructions are found here.

Optional Exercises:

Neural Network Playground

Spend some time with the NN playground.
Challenge: Find architecture and parameters so you get below 2% test loss on the spiral set in less than 1000 training epochs. Also try to minimize the number of used neurons. Hint: Note that you can vary the learning rate while the training is running.

Time series prediction for the Lorentz ODE in matlab

Download, study and run the code NNpred.m and make sure you understand it. Try changing the NN architecture (add or decrease number of layers, change activation functions, vary size of hidden parameters). Can you decrease the network size or training time, while maintaining similar prediction accuracy?

Time series prediction with LSTM in matlab

Download, study and run the code LSTMchickenpox.m. How does the size of hidden state (numHiddentUnits) impact the accuracy and training times?
