Summary: In this paper, we propose a GraphBit method for learning unsupervised deep binary descriptors to efficiently represent images. The method reduces the uncertainty of binary codes by maximizing the mutual information with input and related bits, allowing reliable binarization of ambiguous bits. Additionally, a differentiable search method called GraphBit+ is introduced to mine bitwise interaction in continuous space, reducing the computational cost of reinforcement learning. To address the issue of inaccurate instructions from fixed bitwise interaction, the unsupervised binary descriptor learning method D-GraphBit is proposed, which utilizes a graph convolutional network to reason the optimal bitwise interaction for each input sample.

Summary: In object detection, the commonly used IoU threshold of 0.5 can lead to noisy detections, and performance may degrade for larger thresholds. The Cascade R-CNN architecture addresses this issue by training detectors sequentially with increasing IoU thresholds and eliminating quality mismatches at inference, resulting in state-of-the-art performance and significant improvement in high-quality detection across various datasets. The model is also generalized to instance segmentation, achieving nontrivial improvements over existing methods.

Summary: The paper introduces a new Neural Architecture Search (NAS) method to find a better transformer architecture for image recognition. By incorporating a locality module and new search algorithms, the method allows for a trade-off between global and local information, as well as optimizing low-level design choices in each module. Through extensive experiments on the ImageNet dataset, the method demonstrates the ability to find more efficient and discriminative transformer variants compared to existing models like ResNet101 and ViT.

Summary: A few-shot semantic segmentation model typically consists of a CNN encoder, a CNN decoder, and a simple classifier. This study proposes to simplify the meta-learning task by focusing solely on the classifier while leaving the encoder and decoder to pre-training. Introducing a Classifier Weight Transformer (CWT) for classifier meta-learning, the method outperforms existing alternatives on standard benchmarks.

Summary: The proposed approach in this paper dynamically removes redundant filters by embedding the manifold information of all instances into the space of pruned networks. The effectiveness of the method is verified on several benchmarks, showing better performance in terms of both accuracy and computational cost compared to state-of-the-art methods. This new paradigm maximally excavates redundancy in the network architecture.
