When Do We Not Need Larger Vision Models?

1 code implementation19 Mar 2024 Baifeng Shi, Ziyang Wu, Maolin Mao, Xin Wang, Trevor Darrell

Our results show that a multi-scale smaller model has comparable learning capacity to a larger model, and pre-training smaller models with S$^2$ can match or even exceed the advantage of larger models.

Humanoid Locomotion as Next Token Prediction

no code implementations29 Feb 2024 Ilija Radosavovic, Bike Zhang, Baifeng Shi, Jathushan Rajasegaran, Sarthak Kamat, Trevor Darrell, Koushil Sreenath, Jitendra Malik

We cast real-world humanoid control as a next token prediction problem, akin to predicting the next word in language.

Recursive Visual Programming

no code implementations4 Dec 2023 Jiaxin Ge, Sanjay Subramanian, Baifeng Shi, Roei Herzig, Trevor Darrell

Visual Programming (VP) has emerged as a powerful framework for Visual Question Answering (VQA).

LLM-grounded Video Diffusion Models

no code implementations29 Sep 2023 Long Lian, Baifeng Shi, Adam Yala, Trevor Darrell, Boyi Li

We show that LLMs are able to understand complex spatiotemporal dynamics from text alone and generate layouts that align closely with both the prompts and the object motion patterns typically observed in the real world.

TOAST: Transfer Learning via Attention Steering

1 code implementation24 May 2023 Baifeng Shi, Siyu Gai, Trevor Darrell, Xin Wang

We introduce Top-Down Attention Steering (TOAST), a novel transfer learning algorithm that keeps the pre-trained backbone frozen, selects task-relevant features in the output, and feeds those features back to the model to steer the attention to the task-specific features.

Top-Down Visual Attention from Analysis by Synthesis

1 code implementation CVPR 2023 Baifeng Shi, Trevor Darrell, Xin Wang

In this paper, we consider top-down attention from a classic Analysis-by-Synthesis (AbS) perspective of vision.

Visual Attention Emerges from Recurrent Sparse Reconstruction

1 code implementation23 Apr 2022 Baifeng Shi, Yale Song, Neel Joshi, Trevor Darrell, Xin Wang

We present VARS, Visual Attention from Recurrent Sparse reconstruction, a new attention formulation built on two prominent features of the human visual attention mechanism: recurrency and sparsity.

Temporal Action Detection with Multi-level Supervision

no code implementations ICCV 2021 Baifeng Shi, Qi Dai, Judy Hoffman, Kate Saenko, Trevor Darrell, Huijuan Xu

We extensively benchmark against the baselines for SSAD and OSAD on our created data splits in THUMOS14 and ActivityNet1. 2, and demonstrate the effectiveness of the proposed UFA and IB methods.

Action Detection Semi-Supervised Action Detection

Auxiliary Task Reweighting for Minimum-data Learning

no code implementations NeurIPS 2020 Baifeng Shi, Judy Hoffman, Kate Saenko, Trevor Darrell, Huijuan Xu

By adjusting the auxiliary task weights to minimize the divergence between the surrogate prior and the true prior of the main task, we obtain a more accurate prior estimation, achieving the goal of minimizing the required amount of training data for the main task and avoiding a costly grid search.

Informative Dropout for Robust Representation Learning: A Shape-bias Perspective

1 code implementation ICML 2020 Baifeng Shi, Dinghuai Zhang, Qi Dai, Zhanxing Zhu, Yadong Mu, Jingdong Wang

Specifically, we discriminate texture from shape based on local self-information in an image, and adopt a Dropout-like algorithm to decorrelate the model output from the local texture.
