About | Sijun He

Looks like somebody has stumbled upon my blog!

My name is Sijun He. I am currently a machine learning engineer at Twitter Cortex focusing on Deep Learning and NLP for content understanding. Before that, I was a data scientist at Autodesk, where I did analytics & data mining on products(i.e. AutoCAD, Revit, Maya, etc.) that help engineers design towering skyscrapers and filemakers craft Oscar-winning visual effects.

The blog documents my journey of learning data science from scratch. It will mostly be reading notes and personal projects I have done for work, school or fun. The blog is a journal for myself. Whenever I am upset about not making enough progress (happens ALL THE TIME), I read my blog and remind myself of how far I have gone. If you like the blog, I encourage you to have one for yourself.
