Web26 jun. 2024 · For recurrent nets you'll have a time dimension and a feature dimension. 128 is your feature dimension, as in how many dimensions each embedding vector should have. The time dimension in your example is what is stored in maxlen , which is used to generate the training sequences. Web10 mei 2024 · The usual practice to use a Vision Transformer model on an image having a different resolution than the training one is as follows. Say inferring on 480x480 images as opposed to 224x224 (training resolution). The learned positional (or sin/cosine or relative positional bias) embeddings are interpolated to match the target resolution. While it’s …
