Article Reviews

Theses posts simply summarize what I’ve learned and found in some key research articles that I’ve come across in my research. Full credits are given to the anthors which are listed in each review. I do not provide new information on each topic: I might just give some simplified summaries in my own words.

Shared Experience Actor-Critic for Multi-Agent Reinforcement Learning

Review of a MARL algorithm that enables learning a set of different policies while sharing gradients from a policy to all others. Thus enabling the agents to learn from it’s own on-policy data and also from off-policy data coming from other agents in that environment.

Particle Filtering Tractography

Particle filtering tractography is used to optimize tractography parameters in terms of connectivity and to understand the benefits of a relaxed stopping criterion using partial volume estimation maps.
