Abe & Nakayama (2018) Deep Learning for Forecasting Stock Returns in the Cross-Section

November 30, 2021 paper

A paper to study cross-section return, i.e., return of multiple securities at the same point in time. The models are trivial but good to learn about its approach to the problem. [more]

Glorot & Bengio (2010) Understanding the difficulty of training deep feedforward neural networks

October 15, 2021 paper

This is the paper that explains what caused the gradient vanishing or exploding problem in training neural networks. The approach was to experiment with some fabricated image datasets as well as ImageNet datasets for multi-class classifications. Then some theoretical derivation is provided to support the argument.
