how to multiply two tensor on an axis

let say I got two tensor where tensor A has shape (100,7), tensor B has shape (100,7,64). I want to pick the first item from A and B and multiply them by tf.mat

How can I use tensorflow to create a recommendation system that returns a ratings matrix?

I am trying to use Tensorflow to create a recommendation system. What I want to do is to read data from two csv files, one containing 'item_id' and the other co

Target Data Missing from tensorflow fit()

So I have a problem when train deep learning with BERT with tensorflow which contain text dataset. So i want to fit() the model but got an error when training.

Audio resampling layer for tensorflow

It is required to resample audio signals within a custom model structure. This resampling task is not a kind of pre/post-processing operation that can be develo

how to plot input and output shapes on top of each other using polt_model in keras

I want to plot my model using Keras.utils.plot_model function. my problem is that when I plot the model, the input and output shapes do not place on top of each

How to speed up Tensorflow 2 keras model for inference?

So there's a big update nowadays, moving from TensorFlow 1.X to 2.X. In TF 1.X I got use to a pipeline which helped me to push my keras model to production. Th

How to reset the state of an LSTM RNN after each epoch within Keras?

I have defined a stateful LSTM RNN, and I want to reset the state of the RNN after each epoch. I have found that one way to do this would be: n_epochs = 50 for

How does one invert an encoded prediction in Keras for model serving?

I have a Keras model in which i have successfully added a StringLookUp pre-processing step as part of the model definition. This is generally a good practice be
