class memoryscope.core.worker.backend.ContraRepeatWorker(embedding_model: str = '', generation_model: str = '', rank_model: str = '', **kwargs)

基类：MemoryBaseWorker

The ContraRepeatWorker class specializes in processing memory nodes to identify and handle contradictory and repetitive information. It extends the base functionality of MemoryBaseWorker.

Responsibilities: - Collects observation nodes from various memory categories. - Constructs a prompt with these observations for language model analysis. - Parses the model's response to detect contradictions or redundancies. - Adjusts the status of memory nodes based on the analysis. - Persists the updated node statuses back into memory.

class memoryscope.core.worker.backend.InfoFilterWorker(embedding_model: str = '', generation_model: str = '', rank_model: str = '', **kwargs)

基类：MemoryBaseWorker

This worker filters and modifies the chat message history (self.chat_messages) by retaining only the messages that include significant information. It then constructs a prompt from these filtered messages, utilizes an AI model to process this prompt, parses the AI's generated response to allocate scores, and ultimately retains messages in self.chat_messages based on these assigned scores.
