NEARL: Non-Explicit Action Reinforcement Learning for Robotic Control

Nan Lin, Yuxuan Li, Yujun Zhu +6

Traditionally, reinforcement learning methods predict the next action based on the current state. However, in many situations, directly applying actions to control systems or robot…

Attentive One-Dimensional Heatmap Regression for Facial Landmark Detection and Tracking

Shi Yin, Shangfei Wang, Xiaoping Chen +1

Although heatmap regression is considered a state-of-the-art method to locate facial landmarks, it suffers from huge spatial complexity and is prone to quantization error. To addre…
