TensorBoard as a Zipline dashboard

May 15, 2016

Zipline is a Pythonic algorithmic trading library for backtesting and trading quantitative strategies. TensorBoard is a visualization tool provided with the deep learning library TensorFlow. These two can be used together to create a dashboard that monitors and compares Zipline backtests. You don’t even need to know a thing about deep learning.

Buffered Python generators for data augmentation

September 13, 2015

When using deep convolutional neural networks (CNNs) for image classification tasks, it’s common to apply several transformations to the images in order to augment the data and reduce overfitting. For example, images are often randomly cropped, mirrored, rotated, and blurred to artificially increase the number of training examples. It’s much more efficient to do this in real-time rather than store extra transformed images on disk.
