ML Review 2

This Review gives an overview of intersting stuff I stumbled over which are related to machine learning. Most of it was posted in KITs machine learning group (on Facebook).

A lot of stuff can be found in my article about NIPS 2016.

Quickdraw

Quickdraw is a program which tries to guess what you drew. However, it is difficult to check if they really apply machine learning, because it tells you what to draw and then tries to recognize it.

I had to draw a piano, a floor lamp, a chandelier, a suitcase, a candle and a lipstick each in under 20 seconds.

It looks very much like an attempt to get lots of training data. However, this plan might not work that well: Interesting Quickdraw Fails

You might find more stuff like Quickdraw on aiexperiments.withgoogle.com.

Loss Functions

lossfunctions.tumblr.com is a blog created by Andrej Karpathy where he collects - well, let's call them "interesting" - loss functions.

Eyescream

Have you heard about GANs?

Eyescream is a demo for the generator.

Deep Neural Networks are Easily Fooled

The input of CNNs for image classification can be manipulated in two ways:

  1. An image, on which a human does not recognize anything (e.g. white noise) gets a high score for some object class.
  2. An image on which a human is certain to recognize one class (e.g. "cat") is manipulated in a way that the CNN classifies with high certainty something different (e.g. "factory").

Andrej Karpathy has once again written a nice article. The article describes the problem that linear classifiers can be broken easily.

Hinton commented something simmilar on Reddit.

Software

Seaborn

Example plot generated by Seaborn

Seaborn is a Python package for the visualization of data and statistics.

See stanford.edu/~mwaskom/software/seaborn.

RecNet

Jörg made recnet publicly available. It is a framework based on Theano to simplify the creation of recurrent networks.

Image Segmentation Using DIGITS 5

I didn't try it by now, but the images in the article Image Segmentation Using DIGITS 5 look awesome. I would be happy to hear what you think about it.

Keras.js

Run Keras models (trained using Tensorflow backend) in your browser, with GPU support. Models are created directly from the Keras JSON-format configuration file, using weights serialized directly from the corresponding HDF5 file.

See github.com/transcranial/keras-js for more.
