Few-Shot Specific Emitter Identification Based on Dual Dynamic Universum Contrastive Learning

Specific emitter identification (SEI) is a critical technique for physical-layer security and is widely applied in non-cooperative communications and spectrum management. Current deep neural network approaches for SEI exhibit a strong dependence on labeled data. Moreover, due to subtle radio-frequency fingerprints, the...

In-Context Robot Learning with VLM Agents

GPT-Policy is introduced, a general-agent framework for in-context robot learning that integrates a context compiler that preserves task-relevant visual transitions, a VLM that proposes robot-tool actions, and a constrained controller that verifies and executes each action and reports its outcome.
