arXiv:2405.20510v1 Announce Type: new Abstract: We present a computational framework that transforms single images into 3D physical objects. The visual geometry of a physical object in an image is determined by three orthogonal attributes: mechanical properties, external forces, and rest-shape geometry. Existing single-view 3D reconstruction methods often overlook this underlying composition, presuming rigidity or neglecting external forces. Consequently, the reconstructed objects fail to withstand real-world physical forces, resulting in instability or undesirable deformation -- diverging from their intended designs as depicted in the image. Our optimization framework addresses this by embedding physical compatibility into the reconstruction process. We explicitly decompose…

arXiv:2405.20495v1 Announce Type: new Abstract: Aligning foundation models is essential for their safe and trustworthy deployment. However, traditional fine-tuning methods are computationally intensive and require updating billions of model parameters. A promising alternative, alignment via decoding, adjusts the response distribution directly without model updates to maximize a target reward $r$, thus providing a lightweight and adaptable framework for alignment. However, principled decoding methods rely on oracle access to an optimal Q-function ($Q^*$), which is often unavailable in practice. Hence, prior SoTA methods either approximate this $Q^*$ using $Q^{pi_{texttt{sft}}}$ (derived from the reference $texttt{SFT}$ model) or rely on short-term rewards, resulting…

Investments in GenAI are beginning to create value for organizations according to a new global survey by McKinsey, a leading management consultancy firm.  While 2023 was a year of investing in GenAI initiatives, 2024 is about deriving business value from this new technology. In just one and half years since OpenAI’s ChatGPT was launched, 65% of organizations are now regularly using AI, according to the McKinsey report. This is nearly double the percentage from last year’s survey.  The report suggests that organizations are now using AI in more parts of the business. More than half of the respondents shared that…
