# EfficientRAG Filter (mdeberta-v3-base)

**Filter** component of [EfficientRAG](https://arxiv.org/abs/2408.04259) — constructs next-hop queries via token selection.

## What it does

Given the original question + extracted useful tokens, the Filter selects which tokens to keep in the next retrieval query. This is extractive (no generation) — it picks words from the input.

## Architecture

- Base: `microsoft/mdeberta-v3-base` (86M params, multilingual)
- Standard `DebertaV2ForTokenClassification` with 2 labels (keep/discard)
