A Layered Architecture for Active Perception: Image Classification using Deep Reinforcement Learning

no code implementations20 Sep 2019 Hossein K. Mousavi, Guangyi Liu, Weihang Yuan, Martin Takáč, Héctor Muñoz-Avila, Nader Motee

We propose a planning and perception mechanism for a robot (agent), that can only observe the underlying environment partially, in order to solve an image classification problem.

Hierarchical Reinforcement Learning for Deep Goal Reasoning: An Expressiveness Analysis

no code implementations21 Jun 2020 Weihang Yuan, Héctor Muñoz-Avila

Hierarchical DQN (h-DQN) is a two-level architecture of feedforward neural networks where the meta level selects goals and the lower level takes actions to achieve the goals.

Task Modifiers for HTN Planning and Acting

no code implementations9 Feb 2022 Weihang Yuan, Hector Munoz-Avila, Venkatsampath Raja Gogineni, Sravya Kondrakunta, Michael Cox, Lifang He

The ability of an agent to change its objectives in response to unexpected events is desirable in dynamic environments.

VideoGen: A Reference-Guided Latent Diffusion Approach for High Definition Text-to-Video Generation

no code implementations1 Sep 2023 Xin Li, Wenqing Chu, Ye Wu, Weihang Yuan, Fanglong Liu, Qi Zhang, Fu Li, Haocheng Feng, Errui Ding, Jingdong Wang

In this paper, we present VideoGen, a text-to-video generation approach, which can generate a high-definition video with high frame fidelity and strong temporal consistency using reference-guided latent diffusion.
