I try many times to repeat the result, but my binary_accuracy always 50%, it's horrible. then i find that an issue mention that the positive_sample is the half of batch_size....

Benchmark on encoder representation as comparison

8

It would be nice to run a MLP on the encoder representation to compare the representation learned by the unsupervised encoder in comparison to the full CPC model representation.

Hi David, Its a great repo. I have doubt regarding the final 90% accuracy that you received on the MNSIT dataset in 10 epochs. Isn't that necessarily because of the...

As discussed in the original paper, the training relies on a large number of negative pairs to tighten the lower bound of the Mutual Information, which corresponds to log(N). However,...

Hi @davidtellez, In the readme you report the accuracy of CPC is 99%. But I got ~50%. Here my log: ``` poch 1/10 390/390 [==============================] - 189s 484ms/step - loss:...
