背景
最近发现有一道题，还挺有意思的。题目大意是，每条训练样本是一个文章对，labelA标签标识这两篇文章相似，labelB标签标识这两篇文章属于同一事件(即紧相似)，但这个文章对不会同时拥有两个标签，即要么有A标签，要么有B标签，且A、B标签的文章对不重合。
面对这道题，一般的思路是建立两个模型。但因为标签A、B其实是有相似程度上的联系的，单独训练两个模型就失去了标签的相关性，感觉比较亏。
但如果要训练多任务的单模型，也比较麻烦。因为一个样本不能同时拥有这两个标签，而且比如不属于同一事件，没办法推出是否相似，即无法构造出缺失的标签。
所以想到，利用一个类似mask的特殊标签取值，来控制启用哪个子网络去训练。具体实现措施准备把另一个子网络的loss置0，以此不让其训练。
自定义loss函数
由于标签值是0、1，所以将 -1 设置为mask值，将y_true中的 -1 值，替换为y_pred中的对应值，以此使其对应样本的loss为0。
最后，由于标签是0、1，所以采用 binary_crossentropy 作为损失函数：
def mycrossentropy(y_true, y_pred):
assert len(y_true.shape) == 2
y_true_np = y_true.numpy()
y_pred_np = y_pred.numpy()
tmp = y_pred_np.copy()
for i in range(y_true.shape[0]):
for j in range(y_true.shape[1]):
if y_true_np[i][j] != -1:
tmp[i][j] = y_true_np[i][j]
tmp_tensor = tf.Variable(tmp)
loss = binary_crossentropy(tmp_tensor, y_pred)
return loss
模型定义
在编译模型时指定自定义loss函数，keras会自动对两个输出目标分别使用该自定义loss函数，最后模型算的是这两个loss之和：
def get_model():
K.clear_session()
bert_model = TFBertForPreTraining.from_pretrained(bert_path, from_pt=True)
input_ids = Input(shape=(None,), dtype='int32')
input_token_type_ids = Input(shape=(None,), dtype='int32')
input_attention_mask = Input(shape=(None,), dtype='int32')
bert_output = bert_model({'input_ids':input_ids, 'token_type_ids':input_token_type_ids, 'attention_mask':input_attention_mask}, return_dict=False, training=True)
projection_logits = bert_output[0]
bert_cls = Lambda(lambda x: x[:, 0])(projection_logits) # 取出[CLS]对应的向量用来做分类
dropout_A = Dropout(0.5)(bert_cls)
output_A = Dense(2, activation='sigmoid')(dropout_A)
dropout_B = Dropout(0.5)(bert_cls)
output_B = Dense(2, activation='sigmoid')(dropout_B)
model = Model([input_ids, input_token_type_ids, input_attention_mask], [output_A, output_B])
model.compile(loss=mycrossentropy,
optimizer=Adam(1e-5), #用足够小的学习率
metrics=['accuracy'])
print(model.summary())
return model

Some weights of the PyTorch model were not used when initializing the TF 2.0 model TFBertForPreTraining: ['bert.embeddings.position_ids', 'cls.predictions.decoder.bias']
- This IS expected if you are initializing TFBertForPreTraining from a PyTorch model trained on another task or with another architecture (e.g. initializing a TFBertForSequenceClassification model from a BertForPreTraining model).
- This IS NOT expected if you are initializing TFBertForPreTraining from a PyTorch model that you expect to be exactly identical (e.g. initializing a TFBertForSequenceClassification model from a BertForSequenceClassification model).
All the weights of TFBertForPreTraining were initialized from the PyTorch model.
If your task is similar to the task the model of the checkpoint was trained on, you can already use TFBertForPreTraining for predictions without further training.
The parameter `return_dict` cannot be set in graph mode and will always be set to `True`.
The parameters `output_attentions`, `output_hidden_states` and `use_cache` cannot be updated when calling a model.They have to be set to True/False in the config object (i.e.: `config=XConfig.from_pretrained('name', output_attentions=True)`).
The parameter `return_dict` cannot be set in graph mode and will always be set to `True`.
