Why can't I reproduce my results in keras using random seed?
Are you using a CPU or a GPU?
If you are using a GPU, there is an additional source of randomness.
To confirm this point, you can try to use TensorFlow with CPU only, or disable Cuda DNN but the model ...

Weather impact on plant growth
It's difficult to guess which option is going to give the best results, since it depends on many factors in the data. This is feature engineering, and while there are some general principles it's not ...

How to stop deep learning speech model to not recognize stranger voice?
98% is too high: Your model might overfit actually. Did you apply a drop out of 0.1 or 0.2?
On the other hand, is your model trained on stranger voices?
Otherwise, if there is no existing training for ...

When should one use L1, L2 regularization instead of dropout layer, given that both serve same purpose of reducing overfitting?
It seems deciding between L2 and Dropout is a "guess and check" type of thing, unfortunately. Both are used to make the network more "robust" and reduce overfitting by preventing ...

Reproduce Keras training results in Jupyter Notebook
Did you set the same random seed at each step?
The seed works well for the first function, but then it is lost in the next ones because NumPy applies a global seed reset automatically.
For example, ...

How to further improve on overfitting?
This was an issue I was struggling with for over a week but the eventual problem seemed to be perhaps something in the way the function was done; Initially I used ...

Loss function to prevent estimator bias
Thank you @Nikos M. for your suggestions. I was about to use your post-applied factor but then gave it another try. And found what caused this. It was that the final layer was using a ...

Having weird accuracy graph on deep learning binary classification model
Assuming that the dataset is balanced, my intuition is the following:
From epoch 1 to 55: the loss function being superhigh indicates your model is doing random predictions but with probabilities near ...

Interpreting a curve val_loss and loss in keras after training a model ; help
The training loss decreases while the validation loss increases, which is a clear sign of overfitting. This means that your model is too specific to the training dataset and do not generalize to the ...
