Machine Learning, Deep Learning, Neuroinformatics; Python, MATLAB, LaTeX http://scottclowe.com/ My doctorate studies are finally completed! The work was done, the thesis submitted, viva voce (oral examination) passed, and minor corrections completed, and today is the day of my graduation at Edinburgh. My PhD thesis is titled Decoding information from neural populations in the visual cortex. If you are interested...

Setting the scene Let’s say you’re training a model on a dataset and you need to split it into train and test partitions. You’re doing this so your training...

I’ll be doing the Gaussianisation using the Box-Cox transformation. But first, some background. The need to normalise features Normalising continuous scaled features is widely...

But now, I think I’ve come up with a good solution, which is the rank-hot encoder. Background Continuous data If you’re working with continuous valued fields with a ratio...

Since I wanted a dark-background theme, I had long-ago customised the...
