RefConv: Re-parameterized Refocusing Convolution for Powerful ConvNets

1 code implementation16 Oct 2023 Zhicheng Cai, Xiaohan Ding, Qiu Shen, Xun Cao

We propose Re-parameterized Refocusing Convolution (RefConv) as a replacement for regular convolutional layers, which is a plug-and-play module to improve the performance without any inference costs.

X-MLP: A Patch Embedding-Free MLP Architecture for Vision

no code implementations2 Jul 2023 Xinyue Wang, Zhicheng Cai, Chenglei Peng

However, existing vision MLP architectures always depend on convolution for patch embedding.

Learn to Enhance the Negative Information in Convolutional Neural Network

no code implementations18 Jun 2023 Zhicheng Cai, Chenglei Peng, Qiu Shen

In this way, LENI can enhance the model representational capacity significantly while maintaining the original advantages of ReLU.

FalconNet: Factorization for the Light-weight ConvNets

no code implementations10 Jun 2023 Zhicheng Cai, Qiu Shen

To address these issues, we factorize the four vital components of light-weight CNNs from coarse to fine and redesign them: i) we design a light-weight overall architecture termed LightNet, which obtains better performance by simply implementing the basic blocks of other light-weight CNNs; ii) we abstract a Meta Light Block, which consists of spatial operator and channel operator and uniformly describes current basic blocks; iii) we raise RepSO which constructs multiple spatial operator branches to enhance the representational ability; iv) we raise the concept of receptive range, guided by which we raise RefCO to sparsely factorize the channel operator.

Evolution: A Unified Formula for Feature Operators from a High-level Perspective

no code implementations23 May 2023 Zhicheng Cai

Traditionally, different types of feature operators (e. g., convolution, self-attention and involution) utilize different approaches to extract and aggregate the features.

SA-GD: Improved Gradient Descent Learning Strategy with Simulated Annealing

no code implementations15 Jul 2021 Zhicheng Cai

Compared to the baseline models with traditional gradient descent algorithm, models with SA-GD algorithm possess better generalization ability without sacrificing the efficiency and stability of model convergence.

Interflow: Aggregating Multi-layer Feature Mappings with Attention Mechanism

no code implementations26 Jun 2021 Zhicheng Cai

However, it can be difficulty to settle the optimal network depth and make the middle layers learn distinguished features.

Jitter: Random Jittering Loss Function

no code implementations25 Jun 2021 Zhicheng Cai, Chenglei Peng, Sidan Du

As Jitter point acting as a random factor, we actually add some randomness to the loss function, which is consistent with the fact that there exists innumerable random behaviors in the learning process of the machine learning model and is supposed to make the model more robust.
