我正在尝试运行LSTM,当我使用下面的代码时: model.compile(optimizer='rmsprop', loss='binary_crossentropy', metrics=['accuracy','f1score','precision','recall']) Run Code Online (Sandbox Code Playgroud) 它返回: ValueError: ('Unknown metric function',':f1score'). Run Code Online (Sandbox Code ...
The metrics parameter cannot be a list if one wants to give a name to a custom metric, it has to be a dictionnary (doc defines metrics=['accuracy', mean_pred] ) --> model.compile(optimizer='rmsprop', loss='binary_crossentropy', metrics={'accuracy': mean_pred}) 👍 1 Sign...
Output model.add( Dense( units = 2, activation="softmax") ) model.compile( optimizer = adam, loss = "binary_crossentropy", metrics = ["accuracy"]) Code to save the network: sess = K.get_session() K.set_learning_phase(0) net_model = load_model(weight_file_path) pred = [None]...

A modified binary cross entropy loss function with a weight map was applied to address the reliability issue in different pixels during the network training. Our experimental results showed that the proposed method outperformed the conventional methods. While having a similar performance as the state-...
Additionally, the sparse categorical cross-entropy loss function allows for a simpler optimization process, and the adopted coding approach mitigates issues of linear dependence between labels. Moreover, the approach of the calculating module uses geometrical metrics aids in identifying data that deviate ...
