How to create batches of a list of varying dimension tensors?

Web7 Jan 2024 · In TensorFlow, the first dimension of data often represents a batch. What comes after the batch axis, depends on the problem field. In general, global features (like batch size) precedes element-specific features (like image size). Examples: time-series data are in (batch_size, timesteps, feature) format.

Web7 Apr 2024 · There are three general ways to handle variable-length sequences: Padding and masking (which can be used for (3)), Batch size = 1, and Batch size > 1, with equi-length samples in each batch. Padding and masking In this approach, we pad the shorter sequences with a special value to be masked (skipped) later. Web10. @kbrose seems to have a better solution. I suppose the obvious thing to do would be to find the max length of any sequence in the training set and zero pad it. This is usually a good solution. Maybe try max length of sequence + 100. … Web14 Aug 2024 · We can create this sequence in Python as follows: 1 2 3 length = 10 sequence = [i/float(length) for i in range(length)] print(sequence) Running the example prints our sequence: 1 [0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9] We must convert the sequence to a supervised learning problem. fantasy implications of postponed game
