The most amazing...

...thing I've coded is a variational auto-encoder that uses encoding gradients to generate synthetic data and computationally approximate the Wasserstein distance.

  • A Tour Through TensorFlow with Financial Data (Development)

    A tutorial that runs through implementations of Deep Learning algorithms as applied to the problem of stock market prediction using TensorFlow. It takes the philosophy of using TensorFlow's lowest level tools in order to build a solid understanding of auto-gradient software and the ML algorithms themselves.

    This project has been very popular since it was released, especially since at the time of release (early 2016), TensorFlow was a new technology and tutorials had stayed comfortably in the sphere of toy implementations like MNIST digit recognition. I regularly responded to monthly emails from researchers attempting to replicate the code, many of whom were Ph.D. candidates themselves.
