+## stella model
+
+stella是一个通用的中文文本编码模型，目前有两个版本：base 和 large，**2个版本的模型均支持1024的输入长度**。
+
+完整的训练思路和训练过程已记录在[博客](https://zhuanlan.zhihu.com/p/655322183)，欢迎阅读讨论。
+
+**训练数据：**
+
+1. 开源数据(wudao_base_200GB[1]、m3e[2]和simclue[3])，着重挑选了长度大于512的文本
+2. 在通用语料库上使用LLM构造一批(question, paragraph)和(sentence, paragraph)数据
+
+**训练方法：**
+
+1. 对比学习损失函数
+2. 带有难负例的对比学习损失函数(分别基于bm25和vector构造了难负例)
+3. EWC(Elastic Weights Consolidation)[4]
+4. cosent loss[5]
+5. 每一种类型的数据一个迭代器，分别计算loss进行更新
+
+**初始权重：**\
+stella-base-zh和stella-large-zh分别以piccolo-base-zh[6]和piccolo-large-zh作为基础模型，512-1024的position embedding使用层次分解位置编码[7]进行初始化。\
+感谢商汤科技研究院开源的[piccolo系列模型](https://huggingface.co/sensenova)。
+
+stella is a general-purpose Chinese text encoding model, currently with two versions: base and large, **both of them
+support input lengths of 1024.**
+
+The training data mainly includes:
+
+1. Open-source training data (wudao_base_200GB, m3e, and simclue), with a focus on selecting texts with lengths greater
+   than 512.
+2. A batch of (question, paragraph) and (sentence, paragraph) data constructed on a general corpus using LLM.
+
+The loss functions mainly include:
+
+1. Contrastive learning loss function
+2. Contrastive learning loss function with hard negative examples (based on bm25 and vector hard negatives)
+3. EWC (Elastic Weights Consolidation)
+4. cosent loss
+
+Model weight initialization:\
+stella-base-zh and stella-large-zh use piccolo-base-zh and piccolo-large-zh as the base models, respectively, and the
+512-1024 position embedding uses the initialization strategy of hierarchical decomposed position encoding.
+
+Training strategy:\
+One iterator for each type of data, separately calculating the loss.

+#### Evaluation for long text
+
+经过实际观察发现，C-MTEB的评测数据长度基本都是小于512的，
+更致命的是那些长度大于512的文本，其重点都在前半部分
+这里以CMRC2018的数据为例说明这个问题：
+
+```
+question: 《无双大蛇z》是谁旗下ω-force开发的动作游戏？
+
+passage：《无双大蛇z》是光荣旗下ω-force开发的动作游戏，于2009年3月12日登陆索尼playstation3，并于2009年11月27日推......
+```
+
+passage长度为800多，大于512，但是对于这个question而言只需要前面40个字就足以检索，多的内容对于模型而言是一种噪声，反而降低了效果。\
+简言之，现有数据集的2个问题：\
+1）长度大于512的过少\
+2）即便大于512，对于检索而言也只需要前512的文本内容\
+导致**无法准确评估模型的长文本编码能力。**
+
+为了解决这个问题，搜集了相关开源数据并使用规则进行过滤，最终整理了6份长文本测试集,他们分别是：
+
+- CMRC2018，通用百科
+- CAIL，法律阅读理解
+- DRCD，繁体百科，已转简体
+- Military，军工问答
+- Squad，英文阅读理解，已转中文
+- Multifieldqa_zh，清华的大模型长文本理解能力评测数据[9]
+
+处理规则是选取答案在512长度之后的文本，短的测试数据会欠采样一下，长短文本占比约为1:2，所以模型既得理解短文本也得理解长文本。
+除了Military数据集，我们提供了其他5个测试数据的下载地址：https://drive.google.com/file/d/1WC6EWaCbVgz-vPMDFH4TwAMkLyh5WNcN/view?usp=sharing
+
+评测指标为Recall@5, 结果如下：

+|   **Average**   |      74.98      |      74.83       |    74.76    |    76.15     |   **78.96**    |    **78.24**    | 
+
+
+**注意：** 因为长文本评测数据数量稀少，所以构造时也使用了train部分，如果自行评测，请注意模型的训练数据以免数据泄露。
+
+## Usage
+
+本模型是在piccolo基础上训练的，因此**用法和piccolo完全一致**。\
+**注意**：在stella中instruction里的冒号是英文冒号, 即`查询: `和`结果: `。
+
+在sentence-transformer库中的使用方法：
+
+```python
+# 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('infgrad/stella-base-zh')
+print(model.max_seq_length)
+embeddings_1 = model.encode(sentences, normalize_embeddings=True)
+embeddings_2 = model.encode(sentences, normalize_embeddings=True)
+similarity = embeddings_1 @ embeddings_2.T
+print(similarity)
+# 如果是短对长数据集，推荐添加instruction，来帮助模型更好地进行检索。
+# 注意instruction里的是英文的冒号
+```
+
+直接使用transformers库：
+
+```python
+from transformers import AutoModel, AutoTokenizer
+from sklearn.preprocessing import normalize
+
+model = AutoModel.from_pretrained('infgrad/stella-base-zh')
+tokenizer = AutoTokenizer.from_pretrained('infgrad/stella-base-zh')
+sentences = ["数据1", "数据ABCDEFGH"]
+batch_data = tokenizer(
+    batch_text_or_text_pairs=sentences,
+    padding="longest",
+    return_tensors="pt",
+    max_length=1024,
+    truncation=True,
+)
+attention_mask = batch_data["attention_mask"]
+model_output = model(**batch_data)
+last_hidden = model_output.last_hidden_state.masked_fill(~attention_mask[..., None].bool(), 0.0)
+vectors = last_hidden.sum(dim=1) / attention_mask.sum(dim=1)[..., None]
+vectors = normalize(vectors, norm="l2", axis=1, )
+print(vectors.shape)  # 2,768
+```
+
+## Training Detail
+
+**硬件：** 单卡A100-80GB
+
+**环境：** torch1.13.*; transformers-trainer + deepspeed + gradient-checkpointing
+
+**学习率：** 1e-6
+
+**batch_size：** base模型为1024，额外增加20%的难负例；large模型为768，额外增加20%的难负例
+
+**数据量：** 约100万，其中用LLM构造的数据约有200K. LLM模型大小为13b
+
+## ToDoList
+
+**评测的稳定性：**
+评测过程中发现Clustering任务会和官方的结果不一致，大约有±0.0x的小差距，基本上可以忽略不计，不影响评测结论。\
+但是不完全一样还是比较难理解的，本人试了bge和piccolo系列的模型都存在这个问题，个人猜测可能和使用的库、batch_size等环境有关。
+
+**更高质量的长文本训练和测试数据：** 训练数据多是用13b模型构造的，肯定会存在噪声。
+测试数据基本都是从mrc数据整理来的，所以问题都是factoid类型，不符合真实分布。
+
+**OOD的性能：** 虽然近期出现了很多向量编码模型，但是对于不是那么通用的domain，这一众模型包括stella、openai和cohere,
+它们的效果均比不上BM25。
