Double Descent Curve

This is the code to reproduce Figure 5 and 6 of "The double descent risk curve" blog post on Medium.

This script recovers the double descent curve using random projections plus the RidgeClassifier from scikit-learn. It is possible to choose between a synthetic optical processing unit (OPU) and the real OPU.

Access to Optical Processing Units

To request access to LightOn Cloud and try our photonic co-processor, please visit: https://cloud.lighton.ai/

For researchers, we also have a LightOn Cloud for Research program, please visit https://cloud.lighton.ai/lighton-research/ for more information.

Run the experiments

python ddc_ridgeclassifier.py  # to use synthetic opu on mnist
python ddc_ridgeclassifier.py  -dataset 'cifar10' # to use synthetic opu on cifar10 
python ddc_ridgeclassifier.py -is_real_opu True  # to use opu on mnist with  threshold encoder 
python ddc_ridgeclassifier.py -is_real_opu True  -encoding_method 'autoencoder' # to use opu on mnist with autoencoder 
python ddc_ridgeclassifier.py -is_real_opu True -dataset 'cifar10' # to use opu on cifar10 with  threshold encoder 
python ddc_ridgeclassifier.py -is_real_opu True  -encoding_method 'autoencoder'  -dataset 'cifaro10'# to use opu on cifar10 with autoencoder 

Running ddc_ridgeclassifier.py outputs a .pkl file. To plot the results using this file look at the plot.ipynb example.
