Why shouldn't you mix variable size inputs in the same minibatch?
I am trying to build a CNN-LSTM architecure in tf.keras that classifies sequences of varying sizes. My training data is highly variable and I would have to crop/pad sequences in order to create ...

Predicting the Winner of a sequence of numbers
I have various series of numbers of different lengths (ranging from 4 to 10) such as the example below:
[1.5, 5.0, 6.0, 6.0, 8.0]
[1.4, 6.0, 7.5, 9.0, 50.0, 100.0, 200.0]
For each one of them I ...

Sequence prediction based on non-sequential inputs
I have a dataset with timestamps and event values (true or false -- these are based on sensor data which detect room occupancy). I'd like to build a model that would take a timestamp as an input and ...

Method to predict action based on previous sequence of actions
Given $n-1$ sequences of actions [$k_{i1}$...$k_{in}$] as training/example I want to be able to predict $k_{nn}$ in the sequence [$k_{n1}$...$k_{n(n-1)}$] where $k_{nn}$ would be the most likely ...

How to build a model that maps strings to lists of strings?
I have a mapping from strings to rows in a data table. Each strings maps to exactly one row in a table but the opposite is not generally true (one row can be "bound" to different strings. For example ...

what is "target delay" in the context of RNN/LSTM?
I'm currently reading a paper on sequence-to-sequence classification (speech-to-text) and it is stated that
"there are ways to introduce future context, such as adding a delay
between the ...
