Decoupling Meta-Reinforcement Learning with Gaussian Task Contexts and Skills

1 code implementation11 Dec 2023 Hongcai He, Anjie Zhu, Shuang Liang, Feiyu Chen, Jie Shao

We propose a framework called decoupled meta-reinforcement learning (DCMRL), which (1) contrastively restricts the learning of task contexts through pulling in similar task contexts within the same task and pushing away different task contexts of different tasks, and (2) utilizes a Gaussian quantization variational autoencoder (GQ-VAE) for clustering the Gaussian distributions of the task contexts and skills respectively, and decoupling the exploration and learning processes of their spaces.

Big-Data Clustering: K-Means or K-Indicators?

1 code implementation3 Jun 2019 Feiyu Chen, Yuchen Yang, Liwei Xu, Taiping Zhang, Yin Zhang

The K-means algorithm is arguably the most popular data clustering method, commonly applied to processed datasets in some "feature spaces", as is in spectral clustering.
