Shallow Neural Network Training Coursework
Evaluating a neural network using the MatLab cancer_dataset. Development contained in the nncw.ipynb notebook.
- Evaluate the network's tendency to overfit by varying the number of epochs and hidden layers being used
- Multiple classifier performance using majority vote
- Repeat 2 with two different optimisers (
trainlm,trainrp) - Extension: Distinguish between two equi-probable classes of overlapping 2D Gaussians
Timing
exp 1
CPU: 2min 36s ± 1.66 s per loop (mean ± std. dev. of 2 runs, 2 loops each)
GPU: 3min 5s ± 2.95 s per loop (mean ± std. dev. of 2 runs, 2 loops each)
exp 2
CPU: 26 s ± 62.9 ms per loop (mean ± std. dev. of 2 runs, 2 loops each)
GPU: 57.6 s ± 46.7 ms per loop (mean ± std. dev. of 2 runs, 2 loops each)
