Moving from macbook (without GPU) to linux system with Titan V, only getting a 4x speedup, what am I doing wrong?
This Medium article goes into some surprising performance benchmarking between an M1 and a Titan. M1 systems are very powerful. https://medium.com/macoclock/apple-neural-engine-in-m1-soc-shows-...

How to find the size of a tensor in bytes?
To do this in a line of code, use:
size_in_bytes = encoding.nelement() * encoding.element_size()
This multiplies the number of elements in your tensor by the size ...

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, ...

Features and LSTM
Did you normalize your data with a min-max scaler?
LSTM is a complex neuron, and its size should be adapted enough to your data: very simple models could under-perform because LSTMs are not suited for ...

Odd error when training neural network with Keras - Error occurred when finalizing GeneratorDataset iterator
If it stops always after 36 epochs, it could be due to the data in input.
You should check if the generated data has always the same dimension and same format, without any outlier (like an empty ...

Loss decreases, but Validation Loss just fluctuates
You have 250 images as training set, and you are using a model with millions of parameters... I'm pretty sure that your model is just memorizing the training set, aka you are overfitting.
At this ...

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 ...

Loss decreases, but Validation Loss just fluctuates
It looks like your model is overfitting: it's learning from the training dataset, but this learning doesn't apply to the test dataset. You can try to reduce the complexity of the model by simplifying ...

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 ...

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 ...

Would writing a decision tree algorithm in Pytorch or Tensorflow be faster than with Numpy?
Not directly, mostly because the structure of a decision tree doesn't lend itself to GPU parallelisation, and is better suited to CPUs. Even the most established decision tree algorithms use CPUs.

LSTM RNN regression: validation loss erratic during training
Try using a 'relu' activation function, it might help. Other than that, increase the batch size to check if the loss descent is smoother or not. Even though the graph is erratic, the overall trend of ...

Why do I get an OOM error although my model is not that large?
Coming here as this is a top google result for this issue, and reducing the batch size problem didn't help in my case. Here's my advice:
If you are having this problem during training, my suggestion ...
