MAMBA: Multi-level Aggregation via Memory Bank for Video Object Detection

1 code implementation18 Jan 2024 Guanxiong Sun, Yang Hua, Guosheng Hu, Neil Robertson

However, we argue that these memory structures are not efficient or sufficient because of two implied operations: (1) concatenating all features in memory for enhancement, leading to a heavy computational cost; (2) frame-wise memory updating, preventing the memory from capturing more temporal information.

Explainability of Speech Recognition Transformers via Gradient-based Attention Visualization

1 code implementation IEEE Transactions on Multimedia 2023 Tianli Sun, Haonan Chen, Guosheng Hu, Lianghua He, Cairong Zhao

In addition, we demonstrate the utilization of visualization result in three ways: (1) We visualize attention with respect to connectionist temporal classification (CTC) loss to train an ASR model with adversarial attention erasing regularization, which effectively decreases the word error rate (WER) of the model and improves its generalization capability.

ISTVT: Interpretable Spatial-Temporal Video Transformer for Deepfake Detection

1 code implementation IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY 2023 Cairong Zhao, Chutian Wang, Guosheng Hu, Haonan Chen, Chun Liu, Jinhui Tang

To address these two challenges, in this paper, we propose an Interpretable Spatial-Temporal Video Transformer (ISTVT), which consists of a novel decomposed spatial-temporal self-attention and a self-subtract mechanism to capture spatial artifacts and temporal inconsistency for robust Deepfake detection.

Imbalance Robust Softmax for Deep Embeeding Learning

no code implementations23 Nov 2020 Hao Zhu, Yang Yuan, Guosheng Hu, Xiang Wu, Neil Robertson

IR-Softmax can generalise to any softmax and its variants (which are discriminative for open-set problem) by directly setting the weights as their class centers, naturally solving the data imbalance problem.
