Pred batch_y .sum
WebMar 18, 2024 · This function takes y_pred and y_test as input arguments. We then apply log_softmax to y_pred and extract the class which has a higher probability. After that, we compare the the predicted classes and the actual classes to calculate the accuracy. Web引言 这段时间来，看了西瓜书、蓝皮书，各种机器学习算法都有所了解，但在实践方面却缺乏相应的锻炼。于是我决定通过Kaggle这个平台来提升一下自己的应用能力，培养自己的数据分析能力。 我个人的计划是先从简单的数据集入手如手写数字识别、泰坦尼克号、房价预测，这些目前已经有丰富且 ...

However, The individual losses are averaged over the batch as you can see in the losses.py file. For example this is the code related to binary cross-entropy loss: def binary_crossentropy(y_true, y_pred): return K.mean(K.binary_crossentropy(y_true, y_pred), axis=-1)
