Use it after large > 256 (fully connected layers or convolutional layers). Always use dropout to minimize the chance of overfitting.This tip is from Karpathy, before training on the whole dataset try to overfit on a very small subset of it, that way you know your network can converge.If you are going through voice data shift it and distort it I solved this by creating a layer that applies random transformations so no sample is ever the same.

There is a catch though if the expansion is too big you will be training mostly with the same data. If it is a vision task, add noise, whitening, drop pixels, rotate and color shift, blur and everything in between. I strongly suggest expanding your original dataset. DNN's need a lot of data and the models can easily overfit a small dataset. If your framework allows it shuffle at every epoch. Never allow your network to go through exactly the same minibatch.

However it is such a new concept (even though the foundations were laid in the 70's) that a lot of anecdotal tricks and tips started coming out on how to make the most of it (Alex Krizhevsky covered a lot of them and in some ways pre-discovered batch normalization).Īnyway to sum, these are my tricks (that I learned the hard way) to make DNN tick. Suprisingly, it was no hype, Deep Learning works and it works well. I then went and put to work everything I learned. I needed what Deep Learning promised but I was skeptical, so I read the papers, the books and the notes. Nothing worked good enough and if it did it wouldn't generalize, required fiddling all the time and when introduced to similar datasets it wouldn't perform as well. Then in January 2015 I was involved in a green field project and I was in charge of deciding the core Machine Learning algorithms to be used in a computer vision platform. I followed their evolution but thought it was mostly hype. I first heard of Deep Learning in 2012 when they gained traction against traditional methods.

These pictures are mostly from Linda McCartney: Life in Photographs, a rich, evocative low-key look at the human side of the celebrities we are set up revere – to watch but not always to see. Sadly, Linda passed away at age 56 from breast cancer. Linda famously said “if slaughterhouses had glass walls the whole world would be vegetarian”. As a vegetarian and animal rights activist, Linda wrote several cookbooks, and also created the Linda McCartney Foods company, selling ready made veggie food. During her days as a professional photographer, she published Linda McCartney’s Sixties: Portrait of an Era. Linda was house photographer at the Fillmore East concern hall and shot numerous musicians including the Stones, Doors, Frank Zappa, Kinks, the Who, the Beach Boys, the Byrds, the Beatles etc. Linda was a member of Paul’s band, Wings, and she also wrote/recorded music independently (Seaside woman – Suzy and The Red Stripes). Linda married Paul McCartney in 1969, and the two had three children: Mary Anna, Stella, and James.
