<riksucks> "alastairp: I have been hearing a..." <- i think the issue with the current acousticbrainz model is that to sidestep the fact that we cant store copyrighted music the algorithm tries to get necessary data from the music, so we have to have suitable data that can be trained on
2022-02-14 04514, 2022
tandy1000
but ofc the algo wasnt useful sadly
2022-02-14 04538, 2022

yes the algo did feature extraction and then used SVM iirc

what if we used the dataset that the dude on the forums created?

tandy1000: yeah, you are correct - the current SVM algorithms that we have in the current version of AB work well in some cases, but research has moved on to CNNs and other types of neural networks, and results have shown that the more audio data that you have available, the better they work
2022-02-14 04523, 2022
alastairp
however storing enough data to do that is problematic - you're rght. the current data that we have cannot be reconstructed back into audio, however the much more detailed data used in CNNs can be (even though the quality isn't perfect)
riksucks: you might be interested in looking at some of the results for this challenge - https://multimediaeval.github.io/2021-Emotion-and…, I'm just checking to get the URLs to the rest of the entries, we have source code available
2022-02-14 04547, 2022
alastairp
the other big issue is getting enough training data to build the model, what we're planning to do in listenbrainz now could be a great tool for this, asking users to contribute values for mood
2022-02-14 04505, 2022
alastairp
having the data itself is great, but having a bunch of data validated by people is also good for training the models
2022-02-14 04547, 2022
alastairp
as usual, with this kind of thing, building the model is easy - it's gathering the data and working out if it's useful which is the hard part
2022-02-14 04507, 2022
alastairp
riksucks: I have a few deep learning models for mood from MTG, I have a notebook that runs all combinations, let me upload it for you
2022-02-14 04550, 2022
alastairp
I'm not as familar with the process of training models, but I'll have a look for the code that my coworkers use (we're training on 4 GPUs, this is another problem with deep learning, the hardware resources are much higher than other ML Models)

Also, I'm finally done helping CatQuest document instrument adding, and I think it looks quite good now:
It would be great if someone else who wasn't used to instrument work could check and see if they see something missing, because both of us know how it works and we might have overlooked something that is not obvious for others :)

Last week I had a meeting with zas who explained the MB infrastructure and its history as well as the challenges that need to be resolved in the short to medium term. I created a syswiki page based on this information for future reference. I also spent some time reading various documentation on the syswiki to try and familiarise myself more with the infrastructure and how things work etc.
2022-02-14 04538, 2022
Freso
zas and I then had another meeting to discuss Ansible and how it could be used to simplify deployment, configuration and maintenance of MB infrastructure going forward. I created a simple playbook to run against a test VM to demonstrate some of the concepts and functionality. zas’ feedback was positive and we plan to use Ansible to deploy a replacement server in the near future as a real world test.

tandy1000: you can take a look at these examples: https://andrebola.github.io/EUSIPCO2020/ - (the "examples" link in the first paragraph) and play back some of the examples
2022-02-14 04556, 2022
alastairp
they show how as we remove more and more data, it gets more difficult to reconstruct the audio. however, more data is always useful for training, so it's a tradeoff between what can be reconstructed and the results from your model
2022-02-14 04546, 2022
alastairp
making things more difficult, techniques for _reconstruction_ are always improving too, someone I know did some studies where he took some work that was thought to be not reconstructable and applied some new deep learning techniques to it, and got pretty "good" results
2022-02-14 04552, 2022
alastairp
in specific response to your question - "is reconstructable data able to be stored?", that's a great question, with no absolute clear answer. however in most cases it's probably going to be "no"
2022-02-14 04505, 2022
alastairp
5-10 years ago, the data that we have in AB was used for much of the state-of-the-art research, and while it didn't give as good answers as the more recent deep learning models, it worked well in many cases. This data is impossible to reconstruct, so this wasn't as much of a problem
