Language Models Use Trigonometry to Do Addition "We first discover that numbers are represented in these LLMs as a generalized helix, which is strongly causally implicated for the tasks of addition and subtraction, and is also causally relevant for integer division,…
PreciseCam: Precise Camera Control for Text-to-Image Generation Edurne Bernal-Berdun, Ana Serrano, Belen Masia, Matheus Gadelha, Yannick Hold-Geoffroy, Xin Sun, Diego Gutierrez tl;dr: perspective-field ControlNet arxiv.org/abs/2501.12910
Evaluating Neural Networks at the Speed of Light (with Light!). See live optical inference in the video below. Excited to share recent academic work on optical neural networks as a collection of computing elements embedded in the camera lens! These elements perform computation…
I did another experiment with Runway's outpainting. I wanted to test how much it could reconstruct my face from a video with very little information. The result is impressive once again! Just with the little that can be seen on the sides it managed to reconstruct my face 😮
Excited to share our NeurIPS 2024 Oral, Convolutional Differentiable Logic Gate Networks, leading to a range of inference efficiency records, including inference in only 4 nanoseconds 🏎️. We reduce model sizes by factors of 29x-61x over the SOTA. Paper: arxiv.org/abs/2411.04732
Advanced Camera Control is now available for Gen-3 Alpha Turbo. Choose both the direction and intensity of how you move through your scenes for even more intention in every shot. (1/8)
I'm excited to share our new work, VistaDream, which generates a 3D Gaussian field from a single-view image. The codes have already been released. Project page: vistadream-project-page.github.io (with interactive demos) Code: github.com/WHU-USI3DV/Vis… Paper: arxiv.org/abs/2410.16892
CSS: Overcoming Pose and Scene Challenges in Crowd-Sourced 3D Gaussian Splatting Another paper that builds on top of MASt3R! Paper: arxiv.org/abs/2409.08562
New hobby: pushing 90s video game recordings through Gen-3's Video2Video model. Here's Super Mario 3 as felt.
The Definitive Guide to Testing LLM Applications by LangChain Reviewing LLM app responses can be a time-consuming and daunting process, from defining criteria for style and accuracy, to spotting new regressions. After partnering with hundreds of companies to enhance their GenAI…
We’re launching a new @supabase service: postgres.new It’s like if ChatGPT and Postgres had a love-child: launch as many databases as you want, build them with AI, create charts, create embeddings. 100% open source.
LumiGauss: High-Fidelity Outdoor Relighting with 2D Gaussian Splatting Joanna Kaleta, @kacperkan1, @tomasztrzcinsk1, Marek Kowalski tl;dr: use 2DGS to perform inverse graphics on images taken in the wild arxiv.org/pdf/2408.04474
Gorgeous! 🤩@GMapsPlatform Photorealistic 3D Tiles + @CesiumJS for Unreal = jaw dropping #OlympicGames fly-overs from the @NBCOlympics Graphics team!
I see almost 0 explorations on one of the AI use cases I'm most excited about: using AI to help humans coordinate. The coordination costs of human groups notoriously scales quadratically: the number of potential pair-wise interactions is roughly the square of number of people…
MiniCPM-V A GPT-4V Level MLLM on Your Phone paper page: huggingface.co/papers/2408.01… The recent surge of Multimodal Large Language Models (MLLMs) has fundamentally reshaped the landscape of AI research and industry, shedding light on a promising path toward the next AI milestone.…
Today we release our first foundation model. OCRonos-Vintage is a 124 million parameters model pretrained end-to-end by @pleiasfr on 18 billion tokens of cultural heritage archives, with nearly SOTA results for OCR correction in English huggingface.co/PleIAs/OCRonos…
[1/16] The real world is large, and we want our AI models to operate on the scale of reality. Over the past two years, my colleagues and I have developed fVDB, a deep learning framework for large-scale, high performance spatial intelligence. We finally announced this work at…
1/n Beyond Fine-Tuning: How Sparse Coding is Revolutionizing the Control of Language Models Existing methods for aligning LLMs, essentially steering them towards generating desired outputs while avoiding undesirable ones, have struggled to overcome several key limitations.…
finally – speak any language 🤌
SparseCraft can efficiently reconstruct 3D shapes from as few as three images! It achieves state-of-the-art performance in novel view synthesis and reconstruction from sparse views, requiring less than 10 minutes for training without any pretrained priors. Links ⬇️
