We’re excited for the release of II member @lucab.phd ’s upcoming book, "Hidden Influences: How Algorithmic Recommenders Shape Our Lives." It's a must-read for anyone interested in understanding how recommender systems work and how they can be improved. bit.ly/3NgQZnG

Hidden Influences - Luca Belli
You don’t choose what you see on the internet. Algorithms choose for you. We spend 12 billion hours a day browsing the internet. And in the background, sophisticated recommender systems silently deci...

you probably know your social feeds aren't random. but why you're suddenly getting cat memes isn’t always obvious. often, it's due to it's recommender systems. in our new MEAP, hidden influences, @lucab.phd shares his take from working with 'em at Twitter. get it half off: hubs.la/Q03XnNbz0

* I am very grateful to have attended and had a lot of interesting chats and connections * evals are top of mind for everyone, and so is mental health * the location was great: not only the weather was nice but being able to walk in a real city with real things makes such a huge difference

* it’s always surprising to spot famous names randomly in the halls, or, in my case the same elevator!! * the real value is on the side events and connecting with the people

Heading back from NeurIPS after a very intense week. Some personal thoughts: * the conference is huge, with 29k attendees total (including virtual). It’s very overwhelming especially if you have fomo * at the same time it’s also very humbling to be surrounded by so many great minds

LLMs are powerful tools that are being used to automate more and more tasks. When nuances are important—such as in content moderation—we should ask a lot of questions about their impacts on human rights. @ecnl.bsky.social wrote a great report, where I offered some comments. Read it below:

Drawing on my own experience in auditing Twitter's systems (from the inside), I explore the crucial role business leaders can play in navigating these emerging challenges.

Luca @lucab.phd · 27/03/2025
Audits are going to be a more critical business practice, especially given the increasing regulatory requirements. However they are not a straightforward and linear process, rather a web of different decisions. By their nature, they don't only bring technical challenges, but organizational ones.

General-Purpose AI Code of Practice

☞ Energy consumption (known on estimate) is also something that regulators can demand. This really helps put into perspective the performance of models. There has been a race towards bigger models, but not every task requires the latest and biggest, (e.g. locally run tasks)

Considering the various lawsuits that are happening in the US on this exact topic, it's going to be interesting to see what features and models are NOT going to be released in EU.

☞ Furthermore, regulators can ask more information about how the data was filtered to remove illegal and undesirable content, and how providers have acquired the legal rights to the data.

Luca @lucab.phd · 16/01/2025
☞ Providers will have to disclose to regulators and downstream providers “information on data used for training, testing and validation”. This is particularly important as training data (and their provenance) is considered part of the “secret sauce” of their models

Luca @lucab.phd · 16/01/2025
☞ Providers will have to disclose to the regulators a list of the name of the organization that label data for them. No more hiding behind 3rd party firms

While everyone is focused on the GPAI Code of Practice, this is an important milestone to achieve meaningful transparency for large online platform and search engines operating in the EU. In fact this is unprecedented access from external researchers!

In late October the @ec.europa.eu released a draft of the Delegated Act of Article 40 of the DSA, which mandates data sharing with external researchers. My thoughts on why it matters for @techpolicypress.bsky.social . Special thanks to Justin Hendrix. www.techpolicy.press/data-sharing...
