Hawaii: Hierarchical Visual Knowledge Transfer for Efficient Vision-Language Models

Neural Information Processing Systems

Improving the visual understanding ability of vision-language models (VLMs) is crucial for enhancing their performance across various tasks. While using multiple pretrained visual experts has shown great promise, it often incurs significant computational costs during training and inference. To address this challenge, we propose HAWAII, a novel framework that distills knowledge from multiple visual experts into a single vision encoder, enabling it to inherit the complementary strengths of several experts with minimal computational overhead. To mitigate conflicts among different teachers and switch between different teacher-specific knowledge, instead of using a fixed set of adapters for multiple teachers, we propose to use teacher-specific Low-Rank Adaptation (LoRA) adapters with a corresponding router. Each adapter is aligned with a specific teacher, avoiding noisy guidance during distillation. To enable efficient knowledge distillation, we propose fine-grained and coarse-grained distillation. At the fine-grained level, token importance scores are employed to emphasize the most informative tokens from each teacher adaptively. At the coarse-grained level, we summarize the knowledge from multiple teachers and transfer it to the student using a set of general-knowledge LoRA adapters with a router. Extensive experiments on various vision-language tasks demonstrate the superiority of HAWAII, compared to the popular open-source VLMs.

The Zuckerbergs Are Hiring a Lifeguard but Calling It a 'Beach Water Person'

WIRED

The Zuckerbergs Are Hiring a Lifeguard but Calling It a'Beach Water Person' The job, which is associated with the Zuckerberg family office, is located in Kauai, Hawaii, where the Meta CEO owns a massive compound. Meta CEO Mark Zuckerberg and his wife Priscilla Chan are hiring a seasonal, on-call "Beach Water Person" based in Kauai, Hawaii, where the family owns a sprawling compound, according to a new job listing on Greenhouse associated with West 10, the Zuckerberg family office. This is an interesting choice for a job title, because according to the job description, the primary duties of this "Beach Water Person" include serving as a "Beach Lifeguard," and "Pool Lifeguard." The job listing names a few additional duties related to water activities, such as instructing "stand-up paddleboarding (SUP), canoe paddling, snorkeling, and other ocean-based activities." These, however, come after the water safety duties in the job description.

And rather than singling out a girl they like the most, they're more likely to simply pay for all their girl mates, the study found.

Universality of Gaussian-Mixture Reverse Kernels in Conditional Diffusion

arXiv.org Machine Learning

We prove that conditional diffusion models whose reverse kernels are finite Gaussian mixtures with ReLU-network logits can approximate suitably regular target distributions arbitrarily well in context-averaged conditional KL divergence, up to an irreducible terminal mismatch that typically vanishes with increasing diffusion horizon. A path-space decomposition reduces the output error to this mismatch plus per-step reverse-kernel errors; assuming each reverse kernel factors through a finite-dimensional feature map, each step becomes a static conditional density approximation problem, solved by composing Norets' Gaussian-mixture theory with quantitative ReLU bounds. Under exact terminal matching the resulting neural reverse-kernel class is dense in conditional KL.
