Large Convolutional Model Tuning via Filter Subspace

no code implementations1 Mar 2024 Wei Chen, Zichen Miao, Qiang Qiu

Furthermore, each filter atom can be recursively decomposed as a combination of another set of atoms, which naturally expands the number of tunable parameters in the filter subspace.

Training Bayesian Neural Networks with Sparse Subspace Variational Inference

1 code implementation16 Feb 2024 Junbo Li, Zichen Miao, Qiang Qiu, Ruqi Zhang

Bayesian neural networks (BNNs) offer uncertainty quantification but come with the downside of substantially increased training and inference costs.

Spatiotemporal Joint Filter Decomposition in 3D Convolutional Neural Networks

no code implementations NeurIPS 2021 Zichen Miao, Ze Wang, Xiuyuan Cheng, Qiang Qiu

In this paper, we introduce spatiotemporal joint filter decomposition to decouple spatial and temporal learning, while preserving spatiotemporal dependency in a video.

Learning to Learn Dense Gaussian Processes for Few-Shot Learning

no code implementations NeurIPS 2021 Ze Wang, Zichen Miao, XianTong Zhen, Qiang Qiu

In contrast to sparse Gaussian processes, we define a set of dense inducing variables to be of a much larger size than the support set in each task, which collects prior knowledge from experienced tasks.

Image Generation using Continuous Filter Atoms

no code implementations NeurIPS 2021 Ze Wang, Seunghyun Hwang, Zichen Miao, Qiang Qiu

In this paper, we model the subspace of convolutional filters with a neural ordinary differential equation (ODE) to enable gradual changes in generated images.

Continual Learning with Filter Atom Swapping

1 code implementation ICLR 2022 Zichen Miao, Ze Wang, Wei Chen, Qiang Qiu

In this paper, we first enforce a low-rank filter subspace by decomposing convolutional filters within each network layer over a small set of filter atoms.

Graph Convolution with Low-rank Learnable Local Filters

2 code implementations ICLR 2021 Xiuyuan Cheng, Zichen Miao, Qiang Qiu

Recent deep models using graph convolutions provide an appropriate framework to handle such non-Euclidean data, but many of them, particularly those based on global graph Laplacians, lack expressiveness to capture local features required for representation of signals lying on the non-Euclidean grid.
