🚨How do LLMs acquire human values?🤔 We often point... to preference optimization. However, in our new work, we trace how and when model values shift during post-training and uncover surprising dynamics. We ask: How do data, algorithms, and their interaction shape model values?🧵show more

Diffusions are excellent in creating fantastic images and videos... 🔎 We cooked a *diffusion* model to synthesize structured data #ICLR2025 🔥 Introducing TabDiff, a mixed-type diffusion model for generating synthetic tabular data, imputing missing values, and beyond! 🧵 1/nshow more

Ever wondered how training dynamics differ between LLMs 🖋️... and Vision 👁️ models? We explore this and close the gap between VMs and LLMs in our #NeurIPS2024 paper "TrAct: Making First-layer Pre-Activations Trainable". Paper📜 Video🎥show more

Grasps are one of the primary ways in which... we interact with and shape our environments. How can we faithfully capture human grasps with details such as hand/object shape and contact points? At #CVPR2026, we present MANUS, a method to accurately reconstruct grasps and contacts. 🧵show more

Living in harmony and respecting each other are good... behaviors and values💞👍👍👍🙏Are you agree with me🤔 How we can call this behavior from this 👇👇 movie 🎥🤔show more

Republicans are attacking our democracy. This is how we... chose to respond. California will not sit idle as they shred our democracy. We hope other states join us in defending our democratic values and the voices of voters all across this country.show more

How robust can model predictive control be if we... can solve each trajectory optimization to global optimality? On the contact-rich push-T problem, we show that model-based global optimization is so robust that it never fails, even if the model is not even correct! We achieve global optimality via sparse Moment and SOS relaxations. -- Yes, we managed to solve SDPs online on a robot. Amazing work by Shucheng Kang and Guorui Liu.show more

Coarse2Real (C2R) transfers simple 3D renderings into realistic style... video. Check our paper and project page to learn how to hedge small amount of synthetic paired data with real non-pair data for training the C2R model. We will release the model soon!show more

We built an AI model to simulate how a... fruit fly walks, flies and behaves – in partnership with HHMI | Janelia. 🪰 Our computerized insect replicates realistic motion, and can even use its eyes to control its actions. Here’s how we developed it – and what it means for science. 🧵show more

In 2017, during Tesla’s 'production hell' while scaling up... Model 3 production, Elon Musk camped on the roof of the Nevada Gigafactory, singing Johnny Cash’s 'Ring of Fire' and roasting marshmallows, showing how he is truly dedicated to Tesla and values Tesla investors.show more

His Highness محمد بن زايد “I call on everyone... to abide by values of peace and stability and cooperation” This is our leader… this is how we operate… these values have been instilled into our very fabric as a nation. Now it’s time for the rest of the world to take the UAE as THE blueprint to a successful nation locally and globally.show more

When I look at Jimmy Carter, I see a... man not only for our times, but for all times. A man who embodied the most fundamental human values we can never let slip away. And while we may never see his likes again, we would all do well to try to be a little more like Jimmy Carter.show more

New work: The Value Axis 🎯 How do LLMs... choose which path to take mid-task? We find they internally track the chance of reaching their goal along a linear axis, akin to a value function in RL. We show it modulates confidence in math & coding and can be reshaped with DPO and SFT.show more

President Trump on Iran: “We killed all their leadership.... And then they met to choose new leaders, and we killed all of them. And now we have a new group and we can easily do that. But let’s see how they turn out.” Most based POTUS in history.show more

Disinformation isn't new; it's part of human history. Our... tendency to believe what we want to believe is now amplified by technology. How do we combat this growing threat to democracy and society? Learn more: #wef25show more

We trained our Large Sensor Model (LSM) on over... 40 million hours of de-identified multimodal sensor data from 165K users to demonstrate how it could improve performance in wearable tasks like exercise and activity recognition. Here’s what we found →show more

"How do we define "good and evil", or rather,... what are their measures? Do their definitions change over time? What is the root cause of these phenomena and how did they form in our world?" - Zafar Mirzo Zafar Mirzoshow more

Most of you know the work we do in... GBV, we also do work in women empowerment. The two work in tandem. You know if you invite me to a conference, I stay behind and collect unused pens and notebooks for further use. I mean reduce, reuse and recycle. Lol. But most importantly I pick what we can use for our EMPAWA Mama program on Saturdays. I ask women who can share their skills to come to Soweto and speak to usm This Saturday we celebrated IWD and we did what we do best. Our Chama women met and were trained by one of the best Chama trainers CHAMA Champions who visited and gave great insights on how we can continue to grow VW Babes came to Soweto to participate and support our work and heh we have never seen these many VWs. The ladies stayed and also built our capacity We had a partnership with chiraz International at Jacaranda Hotel as usual we went with our Soweto mamas and there were topics like burnout, toxic relationships led by our own psychologist Njoki Maina. We also learnt first aid and self defense. And Separ will be coming to Soweto to train our ladies in first aid as well as self defense. That is how we Accelerate Action #Usikimyeshow more

When you train it allows you to realise how... much you don’t know. You need to be open to new ideas and willing to learn, which by default means you’ll do things wrong, so this then requires discipline and motivation to over come criticism or any self doubt. All these values are characteristics that will help you in your life outside training. And enjoy it 👊show more

There’s one thing which has stood out in these... 500 days of aggression: the resilience of the brave Ukrainians protecting their homeland & fighting for our shared values. We stood with you from day one and we will continue to do so. For peace with justice, dignity & freedom 🇪🇺🇺🇦show more
