CellAgent: LLM-Driven Multi-Agent Framework for Natural Language-Based Single-Cell Analysis

ICLR 2026poster

Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) data analysis are pivotal for advancing biological research, enabling precise characterization of cellular heterogeneity. However, existing analysis approaches require extensive manual programming and complex tool integration, p…

SWAMamba: A Sliding Window Attention Mamba Framework for Predicting Translation Elongation Rates

AAAI 2025technical

Translation elongation is essential for cellular proteostasis and is implicated in cancer and neurodegeneration. Accurately predicting the rate of ribosome elongation in each codon (also called ribosomal A site) on mRNA is important for understanding and modulating protein synthesis. However, predic…

Designing Biological Sequences without Prior Knowledge Using Evolutionary Reinforcement Learning

AAAI 2024technical

Designing novel biological sequences with desired properties is a significant challenge in biological science because of the extra large search space. The traditional design process usually involves multiple rounds of costly wet lab evaluations. To reduce the need for expensive wet lab experiments,…

A Two Stage Adaptation Framework for Frame Detection via Prompt Learning

COLING 2022main

Framing is a communication strategy to bias discussion by selecting and emphasizing. Frame detection aims to automatically analyze framing strategy. Previous works on frame detection mainly focus on a single scenario or issue, ignoring the special characteristics of frame detection that new events e…

Efficient Deep Reinforcement Learning via Adaptive Policy Transfer

IJCAI 2020poster

Transfer learning has shown great potential to accelerate Reinforcement Learning (RL) by leveraging prior knowledge from past learned policies of relevant tasks. Existing approaches either transfer previous knowledge by explicitly computing similarities between tasks or select appropriate source pol…
