近来在学习TrAdaBoost,非常高兴看到你的GitHub project，请问能否将数据发送给我学习，谢谢。我的邮箱975380678@qq.com。再次感谢

你好，很抱歉，又来打扰。
看到你把源域和辅域权重的更新又修改为戴文渊paper中提到的更新方式，我想冒昧的问一下，你是在哪些数据集上做的验证证明戴的方法是可以收敛的？
我怎么是在你之前提到的权重更新方式下才能收敛，戴的方法不能收敛呢？

请问各位,
为什么鄙人运行出来总是第一次就break,(error_rate=0); 用拟合的模型在测试集上predict,发现AUC在0.7左右(并不是无效分类器).
难道是因为数据的问题?(也就是说不需要boosting,直接用弱学习器就能把training data学习得很好)?
请各位指点迷津,感激不尽.

Thanks for this awsome libaray! I met this problem as I said in the title.
Here is the model information:
```
adam = keras.optimizers.legacy.Adam(learning_rate=0.001, beta_1=0.9, beta_2=0.999, epsi…

想问下有什么代码可以处理中文数据得到输入的矩阵，tradaboost又是否可改成多分类问题？
