# 2 使用方法 |
|
|
|
## 2.1 通用编码模型使用方法 |
|
|
|
直接SentenceTransformer加载即可： |
|
|
|
```python |
|
from sentence_transformers import SentenceTransformer |
|
|
|
model = SentenceTransformer("infgrad/stella-base-zh-v3-1792d") |
|
# model = SentenceTransformer("infgrad/stella-large-zh-v3-1792d") |
|
vectors = model.encode(["text1", "text2"]) |
|
``` |
|
|
|
## 2.2 dialogue编码模型使用方法 |
|
|
|
**使用场景：** |
|
**在一段对话中，需要根据用户语句去检索相关文本，但是对话中的用户语句存在大量的指代和省略，导致直接使用通用编码模型效果不好， |
|
可以使用本项目的专门的dialogue编码模型进行编码** |
|
|
|
**使用要点：** |
|
|
|
1. 对dialogue进行编码时，dialogue中的每个utterance需要是如下格式：`"{ROLE}: {TEXT}"`，然后使用`[SEP]` join一下 |
|
2. 整个对话都要送入模型进行编码，如果长度不够就删掉早期的对话，**编码后的向量本质是对话中最后一句话的重写版本的向量！！** |
|
3. 对话用stella-dialogue-large-zh-v3-1792d编码，被检索文本使用stella-large-zh-v3-1792d进行编码，所以本场景是需要2个编码模型的 |
|
|
|
如果对使用方法还有疑惑，请到下面章节阅读该模型是如何训练的。 |
|
|
|
使用示例： |
|
|
|
```python |
|
from sentence_transformers import SentenceTransformer |
|
|
|
dial_model = SentenceTransformer("infgrad/stella-dialogue-large-zh-v3-1792d") |
|
general_model = SentenceTransformer("infgrad/stella-large-zh-v3-1792d") |
|
# dialogue = ["张三: 吃饭吗", "李四: 等会去"] |
|
dialogue = ["A: 最近去打篮球了吗", "B: 没有"] |
|
corpus = ["B没打篮球是因为受伤了。", "B没有打乒乓球"] |
|
last_utterance_vector = dial_model.encode(["[SEP]".join(dialogue)], normalize_embeddings=True) |
|
corpus_vectors = general_model.encode(corpus, normalize_embeddings=True) |
|
# 计算相似度 |
|
sims = (last_utterance_vector * corpus_vectors).sum(axis=1) |
|
print(sims) |
|
``` |

# 3 通用编码模型训练技巧分享 |
|
|
|
## hard negative |
|
|
|
难负例挖掘也是个经典的trick了，几乎总能提升效果 |
|
|
|
## dropout-1d |
|
|
|
dropout已经是深度学习的标配，我们可以稍微改造下使其更适合句向量的训练。 |
|
我们在训练时会尝试让每一个token-embedding都可以表征整个句子，而在推理时使用mean_pooling从而达到类似模型融合的效果。 |
|
具体操作是在mean_pooling时加入dropout_1d，torch代码如下： |
|
|
|
```python |
|
vector_dropout = nn.Dropout1d(0.3) # 算力有限，试了0.3和0.5 两个参数，其中0.3更优 |
|
last_hidden_state = bert_model(...)[0] |
|
last_hidden = last_hidden_state.masked_fill(~attention_mask[..., None].bool(), 0.0) |
|
last_hidden = vector_dropout(last_hidden) |
|
vectors = last_hidden.sum(dim=1) / attention_mask.sum(dim=1)[..., None] |
|
``` |
|

# 4 dialogue编码模型细节 |
|
|
|
## 4.1 为什么需要一个dialogue编码模型？ |
|
|
|
参见本人历史文章：https://www.zhihu.com/pin/1674913544847077376 |
|
|
|
## 4.2 训练数据 |
|
|
|
单条数据示例： |
|
|
|
```json |
|
{ |
|
"dialogue": [ |
|
"A: 最近去打篮球了吗", |
|
"B: 没有" |
|
], |
|
"last_utterance_rewrite": "B: 我最近没有去打篮球" |
|
} |
|
``` |
|
|
|
## 4.3 训练Loss |
|
|
|
``` |
|
loss = cosine_loss( dial_model.encode(dialogue), existing_model.encode(last_utterance_rewrite) ) |
|
``` |
|
|
|
dial_model就是要被训练的模型，本人是以stella-large-zh-v3-1792d作为base-model进行继续训练的 |
|
|
|
existing_model就是现有训练好的**通用编码模型**，本人使用的是stella-large-zh-v3-1792d |
|
|
|
已开源dialogue-embedding的全量训练数据，理论上可以复现本模型效果。 |
|

|
|
|
## 4.4 效果 |
|
|
|
目前还没有专门测试集，本人简单测试了下是有效果的，部分测试结果见文件`dial_retrieval_test.xlsx`。 |
|
|
|
# 5 后续TODO |
|
|
|
1. 更多的dial-rewrite数据 |
|
2. 不同EmbeddingDimensions的编码模型 |
|
|
|
# 6 FAQ |
|
|
|
Q: 为什么向量维度是1792？\ |
|
A: 最初考虑发布768、1024，768+768，1024+1024，1024+768维度，但是时间有限，先做了1792就只发布1792维度的模型。理论上维度越高效果越好。 |
|
|
|
Q: 如何复现CMTEB效果？\ |
|
A: SentenceTransformer加载后直接用官方评测脚本就行，注意对于Classification任务向量需要先normalize一下 |
|
|
|
Q: 复现的CMTEB效果和本文不一致？\ |
|
A: 聚类不一致正常，官方评测代码没有设定seed，其他不一致建议检查代码或联系本人。 |
|
|
|
Q: 如何选择向量模型？\ |
|
A: 没有免费的午餐，在自己测试集上试试，本人推荐bge、e5和stella. |
|
|
|
Q: 长度为什么只有512，能否更长？\ |
|
A: 可以但没必要，长了效果普遍不好，这是当前训练方法和数据导致的，几乎无解，建议长文本还是走分块。 |
|
|
|
Q: 训练资源和算力？\ |
|
A: 亿级别的数据，单卡A100要一个月起步 |
