[DMP 2024]: Clustering large amount of audio

[dennyabrain]

Ticket Contents

Description

Feluda allows researchers, factcheckers and journalists to explore and analyze large quantity of multimeda content. One important modality on Indian social media is audio. The scope of this task is to explore various automated techniques suited for this grouping similar audio together and visualizing them. After consultation with the team, implement an end to end workflow that can be used to surface visual or temporal trends in a large collection of audio.

Goals

• [ ] Review Literature with our team and do research and prototyping to review state of the art ML and classical DSP techniques
• [ ] Optimize the solution for consistent RAM and CPU usage (limit the spikes caused by variables like file size, video length etc) since it will need to scale up for million videos.
• [ ] Integrate the solution into Feluda by creating a operator that adheres to Feluda operator's interface

Expected Outcome

Feluda's goal is to provide a simple CLI or scriptable interface for Analysing multimodal social media data. In that vein, all the work that you do should be executable and configurable via scripts and config files. The solution should look at feluda's architecture and its various components to identify best ways to enable this. The solution should have a way to configure data source (database with file IDs or a S3 bucket with files), specify and implement the data processing pipeline and where the result will be stored. Our current implementation uses S3 and SQL database for data source and Elasticsearch for storing result but additional sources or stores can be added if apt for this project.

Acceptance Criteria

• [ ] Regular Interactive Demos with the team using a public jupyter notebook pushed to our experiments repository
• [ ] Working feluda operator with tests that can be run as an independent worker in the cloud to schedule processing jobs over a large dataset
• [ ] Output Structured data that can be passed onto a UI service (web or mobile) for downstream use cases

Implementation Details

One way we have approached this is by using Vector Embeddings. We have done this to great success to surface visual trends in Images. We used ResNet model to generate vector embeddings and store them in elasticsearch. We also used t-sne to reduce the dimensions of the vector embeddings to then display them in a 2D visualization. It can be viewed here A detailed report over feluda's usage in a project to analyze images can be read here The relevant feluda operator can be studied here The code for tsne is here A prior study of various ways to get insights out of images has been documented here

Mockups/Wireframes

This is an interactive visualization of Image clustering done using Feluda.

Doing UI development or integrating with any UI software is not part of this project but it might help to see what sort of downstream applications we use Feluda for.

[dennyabrain]

Hi everyone,

Thank you for expressing interest in this issue. Depending on your interests and skills, you can take ANY ONE of the following approaches :

1. Look at the problem statement and propose your approach Remember the main problem statement - Given a large number of audio files, find a way to group identical and similar audio files. This approach would be ideal for anyone who is interested in or studies ML and/or DSP. By thinking about the problem statement, reviewing existing literature on it and proposing your approach here, we would all learn something from it and the mentors should be able to nudge you in the right direction.

2. Try getting feluda working on your machine Feluda is a moderately complex software and has many moving parts. Getting it working on your machine itself can be a challenge. We have a guide on it here. If you are is a software developer/tinkerer, this might be a good place to start because once you have Feluda working locally and you can see the various existing functionalities, that might give you an idea of how to proceed.

3. Recreate our code on a jupyter notebook or google collab notebook We already have some code that takes audio files and converts them into vectors. We also have code that takes these vectors and clusters them. I would take this approach if you are a software engineer with some ML engineering skills and you know your way around using ML models. Once you get this working on your notebook we can try out different pretrained models to evaluate performance.

You'll have me or members from our team to guide if you get stuck on any of these approaches. Taking some conrete steps on any of these 3 steps would help us know what your interests and skills are and give you concrete feedback when you get stuck.

All the best!

[Chaithanya512]

hi @dennyabrain,

I am Chaithanya Kalyan. I am interested in contributing to this project.

I have experience working with time series signals. As part of the PhysioNet 2023 challenge, time domain and frequency domain features were extracted to classify the EEG signals (more details here).

I have a doubt regarding the details of this project and would greatly appreciate the clarification:

1. Does this clustering algorithm have to be scalable to different datasets (like a general framework that can be extended ) or is it only for a specific dataset?

I think the following approach will be worth trying: without extracting the traditional audio features, we can train an autoencoder network on a large audio collection to automatically learn a low-level representation of the audio signals and cluster based on these latent representations.

I have tried a similar approach on EEG signals before, you can find that notebook here.

I would be happy to hear your feedback.

contact: chay5522kalyan@gmail.com

[dennyabrain]

Hi @Chaithanya512,

Given that the project focus is on addressing usecases around online misinformation, the dataset we deal with is usually audio/video found on social media. So it can contain a variety of audio - memes, news clipping, amateur recording from phones etc.

Is there a quick way to validate if the autoencoder network approach would be suitable for this use case? What is your rationale to preferring that over extracting traditional audio features?

[Chaithanya512]

Thank you for the feedback, I am currently working on the code to validate the use of autoencoders.

Compared to traditional, hand-crafted features, autoencoders have the potential to capture a wider range of features. While traditional audio features are valuable, they might miss some subtle patterns in the data that autoencoders can discover.

I have a follow-up question (might be stupid) for your response, please correct me if I am wrong.

I'm curious, do you think traditional audio features are effective in clustering misinformation and not-misinformation? do those features vary for misinformation and not-misinformation?

[dennyabrain]

So we wont be using the clusters to classify something as "misinformation" and "not misinformation". We're hoping to use clustering as a way to find first level of grouping amongst a large dataset. So most likely the clusters could be something high level like "memes", "amateur-smartphone" etc. If we are lucky we could aspire for thematic labels like "politics", "health" etc.

An example of clustering we did on images is here - https://tattle.co.in/articles/covid-whatsapp-public-groups/t-sne/ The clusters we got then were - Screenshots(Social Media), Screenshots(Other), Medical Supplies, Paper Documents, Religious Imagery etc

[Chaithanya512]

thank you for the clarification. That makes sense now. So, we are using clustering only to find the high-level labels/pseudo labels. I have found this paper that uses labeled data (only text) to categorize misinformation posters or active citizens on social media. It got me thinking - if we could obtain the transcriptions of the audio content (if that is possible), that information could significantly enhance our clustering efforts.

[dennyabrain]

@Chaithanya512 yes that would certainly help. Infact when we do clustering for images, we often try to extract any text out of it as a way to get a richer dataset. You can certainly try transcriptions for audio content. One challenge might be that we are dealing with non English languages and also low quality audio.
