Open Source Design Notes on MXNet and Deep Learning Systems
This is a series of notes on system design of deep learning systems. They can help general audiences understand the motivations, benefits and drawbacks of design choices in state-of-art deep learning. This will help deep learning practitioners as well as builders of other deep learning systems. In collaboration with DMLC/MXNet team members.

Introduction to Boosted Trees [Slides]
This is a lecture on gradient boosting and boosted trees I made on Oct. 22, when I am TAing Machine learning in UW.
I am taking the statistical view following the idea of LogitBoost, to present boosted trees algorithm as optimization for training loss and regularization in functional space. This is the model used in the XGBoost package

Introduction to Expression Template
This is an tutorial about expression template. This is the trick that enables efficient and simple machine learning codes in C++
