What's New ~~

2023.3.27

  1. Update simple demo about inference process of Large Language model. Will Update more in the future.

2022.8.31

  1. Update for Diffusion Model. We adopt the code from tutorial And made some necessary changes to the code to make it work locally. The practical training model and inference results can be found in the Diffusion/Result2 folder.

2022.3.25

  1. Thanks to @rattlesnakey's Issue(more discussion detail here). I add Feature in Pretrain Project. Set the Attention Weight of MASK-Token to Zero to prevent MASK-Tokens Self-Attention Each other. You can enable this feature in Transformer.py by setting "self.pretrain=True". PS:The New Feature has not been verified for the time being, and the effect on the pre-training has not been verified. I'll fill in the tests later

2022.1.28

  1. Rebuild the code structure in Transformer. Make Code Easier to Use and deploy
  2. Add Examples: Denoise-Pretrain in Transformer (Easy to use)

2022.1.16

  1. Update use Seq2Seq Transformer to Modeling Medical QA task (Tuing on 55w pairs of Chinese Medical QA data) More detail to be seen in README.md of Transformer/MedQAdemo/
  2. Update new Trainer and useful tools
  3. remove previous implement of Transformer (with some unfixable bugs)

Update History

  2. 增加了Text Classification对应的使用说明

2021.7.2

  1. 增加了MLM预训练技术实践
  2. 修复了句子分类模型里，过分大且不必要的Word Embed（因为太懒，所以只修改了Transformer的）
  3. 在句子分类里增加了加载预训练的可选项
  4. 修复了一些BUG

2021.7.11

  1. 增加了GNN在NLP中的应用
  2. 实现了GNN在文本分类上的使用
  3. 效果不好，暂时怀疑是数据处理的问题

2021.7.29

  1. 增加了CHI+TFIDF传统机器学习算法在文本分类上的应用
  2. 实现和测试了算法性能
  3. 更新了README

2021.8.2

  1. 重构了对话机器人模型于Seq2Seq文件夹
  2. 实现了BeamSearch解码方式
  3. 修复了PGN里的BeamSearch Bug

2021.9.11

  1. 添加了GPT在文本续写和数学题问题的解决（偷了karpathy/minGPT: A minimal PyTorch re-implementation of the OpenAI GPT (Generative Pretrained Transformer) training (github.com)代码实现的很好，对理解GPT很有帮助，偷过来看看能不能用在好玩的东西
  2. 重构了Pointer Generator NetWork，之前的表现一直不好，打算干脆重构，一行一行的重新捋一遍，感觉会安心很多。施工ing。

2021.9.16

  1. 修复了Pretrain里Mask Token未对齐，位置不一致问题

2021.9.29

  1. 在Transformer里增加了一个随机数字串恢复的Demo，对新手理解Transformer超友好，不需要外部数据，利用随机构造的数字串训练
  2. 新增实验TransfomerVAE，暂时有BUG，施工中

2021.11.20

  1. update BM25 and TF-IDF algorithm for quick match of Text.

2021.12.10

  1. Update Practical use of Pytorch_Lighting, Use Text_classification as Example. Convert the Pytorch to LightningLite. More details in LightingMain.py。
  2. Remove the redundant code

2021.12.9

  1. update Practical use of Amp(Automatic Mixed Precision). Implement in VAEGenerator, Test on local MX150, Significant improve the training time and Memory-Usage, More details in Comments at the end of the code
  2. Based the command of Amp, Modified the definition of 1e-9 to inf in model.py

2021.12.17
