R1-D1-06 Millions way to avoid overfitting when building a portfolio - Chia-Yi Yen (PyCon APAC 2015)


Speaker: Chia-Yi Yen

You never know how to build a successful portfolio that always gives you significant return, but you definitely should know what would make you build a model that is doomed to be a failure.

Overfitting is the most common one. In the brief talk, I would like to share some experience how to avoid overfitting. At least in some ways.

The examples would be shown in Python toolkit like ipython, pandas, numpy, matplotlib, and seaborn.
