Foundation Model is Efficient Multimodal Multitask Model Selector

1 code implementation NeurIPS 2023 Fanqing Meng, Wenqi Shao, Zhanglin Peng, Chonghe Jiang, Kaipeng Zhang, Yu Qiao, Ping Luo

This paper investigates an under-explored but important problem: given a collection of pre-trained neural networks, predicting their performance on each multi-modal task without fine-tuning them, such as image recognition, referring, captioning, visual question answering, and text question answering.

Active Domain Adaptation with Multi-level Contrastive Units for Semantic Segmentation

no code implementations23 May 2022 Hao Zhang, Ruimao Zhang, Zhanglin Peng, Junle Wang, Yanqing Jing

A simple pixel selection strategy followed with the construction of multi-level contrastive units is introduced to optimize the model for both domain adaptation and active supervised learning.

Exemplar Normalization for Learning Deep Representation

no code implementations CVPR 2020 Ruimao Zhang, Zhanglin Peng, Lingyun Wu, Zhen Li, Ping Luo

This work investigates a novel dynamic learning-to-normalize (L2N) problem by proposing Exemplar Normalization (EN), which is able to learn different normalization methods for different convolutional layers and image samples of a deep network.

Differentiable Learning-to-Group Channels via Groupable Convolutional Neural Networks

no code implementations ICCV 2019 Zhaoyang Zhang, Jingyu Li, Wenqi Shao, Zhanglin Peng, Ruimao Zhang, Xiaogang Wang, Ping Luo

ResNeXt, still suffers from the sub-optimal performance due to manually defining the number of groups as a constant over all of the layers.

Switchable Normalization for Learning-to-Normalize Deep Representation

no code implementations22 Jul 2019 Ping Luo, Ruimao Zhang, Jiamin Ren, Zhanglin Peng, Jingyu Li

Analyses of SN are also presented to answer the following three questions: (a) Is it useful to allow each normalization layer to select its own normalizer?

Do Normalization Layers in a Deep ConvNet Really Need to Be Distinct?

no code implementations19 Nov 2018 Ping Luo, Zhanglin Peng, Jiamin Ren, Ruimao Zhang

Our results suggest that (1) using distinct normalizers improves both learning and generalization of a ConvNet; (2) the choices of normalizers are more related to depth and batch size, but less relevant to parameter initialization, learning rate decay, and solver; (3) different tasks and datasets have different behaviors when learning to select normalizers.

Geometric Scene Parsing with Hierarchical LSTM

no code implementations7 Apr 2016 Zhanglin Peng, Ruimao Zhang, Xiaodan Liang, Xiaobai Liu, Liang Lin

This paper addresses the problem of geometric scene parsing, i. e. simultaneously labeling geometric surfaces (e. g. sky, ground and vertical plane) and determining the interaction relations (e. g. layering, supporting, siding and affinity) between main regions.

Deep Boosting: Joint Feature Selection and Analysis Dictionary Learning in Hierarchy

no code implementations8 Aug 2015 Zhanglin Peng, Ya Li, Zhaoquan Cai, Liang Lin

In each layer, we construct a dictionary of filters by combining the filters from the lower layer, and iteratively optimize the image representation with a joint discriminative-generative formulation, i. e. minimization of empirical classification error plus regularization of analysis image generation over training images.
