"Approximating CNNs with Bag-of-local-Features models works surprisingly well on ImageNet"

A "bag of words" of nets on tiny 17x17 patches suffice to reach AlexNet-level performance on ImageNet. A lot of the information is very local.

​​How 20th Century Fox uses ML to predict a movie audience

All modern blockbusters seem the same. They have common patterns of more exciting periods following less exciting, rotating emotional moments with action period. It is more about following well-known structure and template to make a well-boxing movie, than about director’s skill. No suprise, that #ML can be used to predict success of the movie by its trailer.

Time series basics

Time series — data, with points having timestamps. Some might think that #timeseries are mostly used in algorithmic trading, but they often used in malware detection, network data analysis or any other field, dealing with some flow of time-labeled data. These two resources provide deep and easy #introduction into #TS analysis.
