Human Activity Knowledge Engine (HAKE) aims at promoting human activity understanding. As a large-scale knowledge base, HAKE is built upon existing activity datasets and provides human body part level atomic action labels (Part States). Given a human box, Activity2Vec will convert it into a fixed-size vector combining visual and linguistic features for diverse downstream tasks, i.e. image/video action recognition/detection, captioning, VQA, visual reasoning, image retrieval, etc. Conventional instance-based methods enhanced with HAKE outperform SOTA approaches on several large-scale activity benchmarks (HICO, HICO-DET, V-COCO, AVA, etc).
Now we are enriching HAKE to make it become a general research platform of knowledge extraction and causal inference. Come and join us!
