Rushiv has been doing this neat work trying to understand how to bring language into multi-task learning.
I’m very excited to share my new paper introducing LEXical POLicy Networks (LEXPOL) for Multi-Task Reinforcement Learning!



In LEXPOL, language acts as a gate that routes among reusable sub-policies (skills) to solve diverse tasks.

Multi-Task Reinforcement Learning with Language-Encoded Gated Policy Networks
Multi-task reinforcement learning often relies on task metadata -- such as brief natural-language descriptions -- to guide behavior across diverse objectives. We present Lexical Policy Networks (LEXPO...

Excited to share that an abstract of this paper was accepted at RLDM!

I’m genuinely excited to go for the conference—it is one of my favorite venues for interdisciplinary discussions!

I am thrilled to announce that I am running the 2025 New York City Marathon for the National Ovarian Cancel Coalition.

I would be grateful if you would consider donating or sharing the message to help me fundraise for this very important cause! Every share counts!

First post on here and it’s an exciting one! I am happy to share my new paper “Hierarchical Universal Value Function Approximators” (H-UVFAs): arxiv.org/abs/2410.08997
Hierarchical Universal Value Function Approximators
There have been key advancements to building universal approximators for multi-goal collections of reinforcement learning value functions -- key elements in estimating long-term returns of states in a...
