Why do AI-generated images of food look slightly off? Chris Russell @cruss.bsky.social explains to @theverge.com why image models can produce some strange results.

"The concern is that while an AI is trained to give neutral-sounding answers, there are many places in this process to insert bias and shape the answers" @cruss.bsky.social @oii.ox.ac.uk told @carlottad.bsky.social for @opendemocracy.net. Read the piece: www.opendemocracy.net/ai-chatbots-...

News! Latest @oii.ox.ac.uk research finds that AI writing tools can subtly shift the direction of social media posts on contested topics, even when instructed to preserve the original meaning, and that these changes can accumulate and influence public opinion over time. 1/3

The 4th Monocular Depth Estimation Challenge (MDEC) is coming to #CVPR2025, and I’m excited to join the org team! After 2024’s breakthroughs in monodepth driven by generative model advances in transformers and diffusion, this year's focus is on OOD generalization and evaluation.

The trick is model surgery on a validation set. We train a multi-head model, the first head solves the original task and the other heads predict groups using a squared loss. A weighted sum of all these heads can enforce any fairness definition, and has the same architecture as the original net

New fairness toolkit at #NeurIPS today. This fixes most of the problems I've run into in the field. It is robust to overfitting, works for #NLP and computer vision, and can enforce any definition of fairness that can be written as a function of a confusion matrix. t.ly/ZpRJ- How do we do that....

This is a common problem with LLMs if the temperature is set to zero. It might just be that these small models need a higher temperature.
