Real-world examples

[loretoparisi]

Hello, thanks for this project! Despite the MNIST provided example is ok for learning the basis, more real-world indexing and querying examples for contrastive learning use cases would be helpful. By example, audio files search, video files search, text documents similarity search, et.
Specifically more details on which Keras layers to use to embed those kind of documents (audio, text, video) would be helpful though.

Thanks a lot.

Another example I would love to see is tensorboard used for exploring the embeddings.

Update: something very similar is already done in https://github.com/tensorflow/similarity/blob/master/examples/supervised_visualization.ipynb
