HAKE: Human Activity Knowledge Engine

Introduction

Human Activity Knowledge Engine (HAKE) is a knowledge-driven system that aims at enabling intelligent agents to perceive human activities, reason human behavior logics, learn skills from human activities, and interact with objects and environments. In detail, HAKE contains 26 M+ human body part-level atomic action labels (Part States, PaSta) and PaSta-Activity logic rules, holistic object knowledge labels (category, attribute, affordance) together with their causal relations. It boosts the performances of several widely-used human activity- and object- related benchmarks (HICO, HICO-DET, V-COCO, AVA, Ambiguous-HOI, MIT-States, UT-Zappos, aPY, SUN, etc), and can convert human boxes into multi-modal representations for diverse downstream tasks, e.g., image/video action recognition/detection, captioning, VQA, visual reasoning, etc. Now, the HAKE project contains the works from 8 papers (CVPR'18/19/20/22, NeurIPS'20, TPAMI'21, AAAI'22). In the near future, we will release more works on object concept learning, visual reasoning, and human-robot interaction.

We will keep enriching HAKE to make it a general research platform of knowledge mining, visual reasoning, and causal inference. Come and join us!
