Adaptive Self-Supervised Learning Strategies for Dynamic On-Device LLM Personalization

no code implementations25 Sep 2024 Rafael Mendoza, Isabella Cruz, Richard Liu, Aarav Deshmukh, David Williams, Jesscia Peng, Rohan Iyer

Large language models (LLMs) have revolutionized how we interact with technology, but their personalization to individual user preferences remains a significant challenge, particularly in on-device applications.

General targeted machine learning for modern causal mediation analysis

1 code implementation26 Aug 2024 Richard Liu, Nicholas T. Williams, Kara E. Rudolph, Iván Díaz

Causal mediation analyses investigate the mechanisms through which causes exert their effects, and are therefore central to scientific progress.

Invariant Discovery of Features Across Multiple Length Scales: Applications in Microscopy and Autonomous Materials Characterization

no code implementations1 Aug 2024 Aditya Raghavan, Utkarsh Pratiush, Mani Valleti, Richard Liu, Reece Emery, Hiroshi Funakubo, Yongtao Liu, Philip Rack, Sergei Kalinin

Here we introduce the scale-invariant VAE approach (SI-VAE) based on the progressive training of the VAE with the descriptors sampled at different length scales.

HyperFields: Towards Zero-Shot Generation of NeRFs from Text

no code implementations26 Oct 2023 Sudarshan Babu, Richard Liu, Avery Zhou, Michael Maire, Greg Shakhnarovich, Rana Hanocka

We introduce HyperFields, a method for generating text-conditioned Neural Radiance Fields (NeRFs) with a single forward pass and (optionally) some fine-tuning.

TEDi: Temporally-Entangled Diffusion for Long-Term Motion Synthesis

no code implementations27 Jul 2023 Zihan Zhang, Richard Liu, Kfir Aberman, Rana Hanocka

The gradual nature of a diffusion process that synthesizes samples in small increments constitutes a key ingredient of Denoising Diffusion Probabilistic Models (DDPM), which have presented unprecedented quality in image synthesis and been recently explored in the motion domain.

DA Wand: Distortion-Aware Selection using Neural Mesh Parameterization

1 code implementation CVPR 2023 Richard Liu, Noam Aigerman, Vladimir G. Kim, Rana Hanocka

We present a neural technique for learning to select a local sub-region around a point which can be used for mesh parameterization.

Text2Mesh: Text-Driven Neural Stylization for Meshes

1 code implementation CVPR 2022 Oscar Michel, Roi Bar-On, Richard Liu, Sagie Benaim, Rana Hanocka

In order to modify style, we obtain a similarity score between a text prompt (describing style) and a stylized mesh by harnessing the representational power of CLIP.

A Scalable and Cloud-Native Hyperparameter Tuning System

1 code implementation3 Jun 2020 Johnu George, Ce Gao, Richard Liu, Hou Gang Liu, Yuan Tang, Ramdoot Pydipaty, Amit Kumar Saha

In this paper, we introduce Katib: a scalable, cloud-native, and production-ready hyperparameter tuning system that is agnostic of the underlying machine learning framework.
