Inspired from E5 and GTE, piccolo is trained using a two stage pipeline. On the first stage, we collect and crawl 400 million weakly supervised Chinese text pairs from the Internet, and train the model with the pair(text and text pos) softmax contrastive loss. On the second stage, we collect 20 million human labeled chinese text pairs dataset, and finetune the model with tiplet (text, text_pos, text_neg) contrastive loss. Currently here we offer two different sizes of models, including piccolo-base-zh, piccolo-large-zh. ## Metric 我们将piccolo与其他的开源embedding模型在CMTEB榜单上进行了比较，请参考CMTEB榜单。我们在eval文件夹中提供了复现结果的脚本。 We compared the performance of the piccolo with other embedding models on the C-MTEB benchmark. please refer to the C-MTEB leaderboard. we provide scripts in "eval" folder for results reproducing. | Model Name | Model Size (GB) | Dimension | Sequence Length | Average (35) | Classification (9) | Clustering (4) | Pair Classification (2) | Reranking (4) | Retrieval (8) | STS (8) | |:----:|:---:|:---:|:---:|:---:|:---:|:---:|:---:|:---:|:---:|:---:| | [**piccolo-large-zh**] | 0.65 | 1024 | 512 | **64.11** | 67.03 | 47.04 | 78.38 | 65.98 | 70.93 | 58.02 | | [bge-large-zh]| 1.3 | 1024| 512 | 63.96 | 68.32 | 48.39 | 78.94 | 65.11 | 71.52 | 54.98 | | [**piccolo-base-zh**]| 0.2 | 768 | 512 | **63.66** | 66.98 | 47.12 | 76.61 | 66.68 | 71.2 | 55.9 | | [bge-large-zh-no-instruct]| 1.3 | 1024 | 512 | 63.4 | 68.58 | 50.01 | 76.77 | 64.9 | 70.54 | 53 | | [bge-base-zh]| 0.41 | 768 | 512 | 62.8 | 67.07 | 47.64 | 77.5 | 64.91 | 69.53 | 54.12 | ## Usage 在sentence-transformer package中可以很容易地调用piccolo模型 ```python # for s2s dataset, you can use piccolo as below # 对于短对短数据集，下面是通用的使用方式 from sentence_transformers import SentenceTransformer sentences = ["数据1", "数据2"] model = SentenceTransformer('sensenova/piccolo-base-zh') embeddings_1 = model.encode(sentences, normalize_embeddings=True) embeddings_2 = model.encode(sentences, normalize_embeddings=True) similarity = embeddings_1 @ embeddings_2.T print(similarity) # for s2p dataset, we recommend to add instruction for passage retrieval # 对于短对长数据集，我们推荐添加instruction，来帮助模型更好地进行检索。 from sentence_transformers import SentenceTransformer queries = ['query_1', 'query_2'] passages = ["doc_1", "doc_2"] model = SentenceTransformer('sensenova/piccolo-base-zh') q_embeddings = model.encode(["查询：" + q for q in queries], normalize_embeddings=True) p_embeddings = model.encode(["结果：" + p for p in passages], normalize_embeddings=True) scores = q_embeddings @ p_embeddings.T ``` ## Training Detail TODO ## acknowledgement piccolo is powered by Genral Model group from SenseTime Research. [Jinkin](https://huggingface.co/Jinkin) complete code implementation and model training. [Jinkin](https://huggingface.co/Jinkin), [CCCCxxx](https://huggingface.co/CCCCxxx) completed the data collection、processing and model evaluation together.
