Annotation-Free Class-Incremental Learning

A recent study introduces BD-Net, which successfully applies depth-wise convolution in Binary Neural Networks (BNNs) by proposing a 1.58-bit convolution and a pre-BN residual connection to enhance expressiveness and stabilize training. This innovation marks a significant advancement in model compression techniques, achieving a new state-of-the-art performance on ImageNet with MobileNet V1 and outperforming previous methods across various datasets.

CUS-GS, a new framework for multimodal scene representation, has been introduced, integrating semantics and structured 3D geometry through a voxelized anchor structure and a multimodal latent feature allocation mechanism. This approach aims to enhance the understanding of spatial structures while maintaining semantic abstraction, addressing the limitations of existing methods in 3D scene representation.

The newly proposed DeCo framework introduces a frequency-decoupled pixel diffusion method for end-to-end image generation, addressing the inefficiencies of existing models that combine high and low-frequency signal modeling within a single diffusion transformer. This innovation allows for improved training and inference speeds by separating the generation processes of high-frequency details and low-frequency semantics.

A new study introduces Temporal-adaptive Weight Quantization (TaWQ) for Spiking Neural Networks (SNNs), which aims to reduce energy consumption while maintaining accuracy. This method leverages temporal dynamics to allocate ultra-low-bit weights, demonstrating minimal quantization loss of 0.22% on ImageNet and high energy efficiency in extensive experiments.

A new approach to flow map distillation has been introduced, which eliminates the need for external datasets traditionally used in the sampling process. This method aims to mitigate the risks associated with Teacher-Data Mismatch by relying solely on the prior distribution, ensuring that the teacher's generative capabilities are accurately represented without data dependency.

Recent advancements in MeanFlow training have clarified the dynamics between instantaneous and average velocity fields, revealing that effective learning of average velocity relies on the prior establishment of accurate instantaneous velocities. This understanding has led to the design of a new training scheme that accelerates the formation of these velocities, enhancing the overall training process.

Recent advancements in generative models, particularly GANs and Diffusion Models, have complicated the detection of AI-generated images. A new study highlights the effectiveness of CLIP-based detectors, which leverage semantic cues and introduces a method called SemAnti that fine-tunes these detectors by freezing the semantic subspace, enhancing their robustness against distribution shifts.

A systematic study has been conducted on knowledge distillation (KD) applied to CLIP-style vision-language models (VLMs) in visual question answering (VQA), revealing that stronger teacher models do not consistently produce better student models, which challenges existing assumptions in the field.
