AutoTAMP: Autoregressive Task and Motion Planning with LLMs as Translators and Checkers

3 code implementations10 Jun 2023 Yongchao Chen, Jacob Arkin, Charles Dawson, Yang Zhang, Nicholas Roy, Chuchu Fan

Rather than using LLMs to directly plan task sub-goals, we instead perform few-shot translation from natural language task descriptions to an intermediate task representation that can then be consumed by a TAMP algorithm to jointly solve the task and motion plan.

NL2TL: Transforming Natural Languages to Temporal Logics using Large Language Models

3 code implementations12 May 2023 Yongchao Chen, Rujul Gandhi, Yang Zhang, Chuchu Fan

Then, we finetune T5 models on the lifted versions (i. e., the specific Atomic Propositions (AP) are hidden) of the NL and TL.

FedSSC: Shared Supervised-Contrastive Federated Learning

no code implementations14 Jan 2023 Sirui Hu, Ling Feng, Xiaohan Yang, Yongchao Chen

We propose Supervised Contrastive Federated Learning in which devices can share the learned class-wise feature spaces with each other and add the supervised-contrastive learning loss as a regularization term to foster the feature space learning.
