ConvMemory Chinese Dual-Space GTE Student

What This Checkpoint Is

This is the representative checkpoint for the Chinese ConvMemory dual-space reranker.

The online inference structure is:

query/memory text -> base GTE embedding + triplet-GTE embedding -> normalized dual-space vector -> ConvMemory window encoder -> CE-lite reranker

It is not an online cross-encoder. The Jina reranker was used only as an offline teacher during training.

Intended Use

Use this checkpoint as a plug-and-play Chinese retrieval/reranking module through the convmemory package:

python

from convmemory import ChineseConvMemory

model = ChineseConvMemory.from_pretrained("Purdy0228/ConvMemory-ZH-DualSpace-GTE")
ranked = model.rerank("用户最近喜欢什么音乐？", memories, top_k=10)

This is a Chinese retrieval/reranking checkpoint, not the validity-context module.

Assets

Lightweight student weights: student.pt
Config and provenance: config.json, MANIFEST.json
Base encoder dependency: Alibaba-NLP/gte-multilingual-base
Bundled tuned encoder: triplet_encoder/

The Hub repository bundles the tuned SentenceTransformer under triplet_encoder/, so users only need the repo id plus the base encoder dependency. student.pt stores the lightweight ConvMemory student; the tuned encoder is packaged beside it for plug-and-play loading.
