Spatial Temporal Graph Convolutional Networks for Skeleton-Based Action Recognition
Today we released the paper, together with code and modes, of our AAAI 2018 publication “Spatial Temporal Graph Convolutional Networks for Skeleton-Based Action Recognition“. This work is one of my most liked papers in recent years. It provides an elegant way to deal with temporal dynamic graphs such as skeleton sequences. Without any feature or…

Kinetics Pretrained TSN Models Released
Kinetics Human Action Video Dataset is a large-scale video action recognition dataset released by Google DeepMind. It contains around 300,000 trimmed human action videos from 400 action classes. This year (2017), it served in the ActivityNet challenge as the trimmed video classification track. During our participation in the challenge, we have confirmed that our TSN framework published in ECCV 2016 works smoothly on…

Squeezing Memory out of Caffe
No, I am not talking about thinking of the good old days with a cup of drink. Today we are talking about our recent release of a new feature in our modified version of deep learning toolbox, Caffe. https://github.com/yjxiong/caffe In this release, we have implemented the functionality usually referred to as “memory multiloading”. A Wiki…

ECCV Paper: Temporal Segment Networks: Towards Good Practices in Deep Action Recognition
We just released the code for Temporal Segment Networks (TSN) accepted to ECCV 2016. Github: Temporal Segment Networks In this release, we not only want to showcase the research work, but also mean to provide an accessible framework that will lower the barrier of entrance for research in action recognition or more general video understanding.…

MPI Broadcast
One interesting answer I saw on Stack Overflow. Someone asked how he can receive the msg send by `MPI_Bcast`. The answer is This is a common source of confusion for people new to MPI. You don’t use MPI_Recv() to receive data sent by a broadcast; you use MPI_Bcast(). For MPI collective communications, everyone has to particpate; everyone has to call…

Face Recognition新进展
Facebook刚刚公布了他们在CVPR2014的Oral文章 DeepFace: Closing the Gap to Human-Level Performance in Face Verification 文章题目就取得很霸气。Facebook的人用四百万人脸图片训练了一个九层的卷积神经网络(CNN)，在著名的公共测试数据集LFW（labeled face in the wild）上达到了97.25%的正确率。这个数字已经基本接近人眼的辨识水平。
