Did Pennylane delete the demo of quantum metric learning?

I am reading the paper Quantum embeddings for machine learning. I remember that the previous demo of Pennylane contained the code of this article, but recently opened it and found that it is gone. Is it officially deleted?

Hey @Cc1! Yep, this demo was deleted.

Thank you very much for your reply, so where else can I find the demo code of quantum metric learning? Thanks.

The demo isn’t available anywhere to my knowledge.

Let me see if I can figure out why @Cc1!

Thank you very much for your help!

Hey @Cc1!

This is entirely my fault, I realised that the demo contained a bug (I accidentally used training data for testing, uuuh!). Once fixed, the model we showcased, adding a small quantum feature map to a big classical model, hopelessly overfitted. I simply did not have the time to look into this, and it seemed to be a deeper problem that needs some more research.

Since there are still requests for that demo I will have another look at the problem in the next 1-2 months and let you know in this thread if we can upload it again.

Hope that helps!
