DTMM: Deploying TinyML Models on Extremely Weak IoT Devices with Pruning

no code implementations17 Jan 2024 Lixiang Han, Zhen Xiao, Zhenjiang Li

DTMM is a library designed for efficient deployment and execution of machine learning models on weak IoT devices such as microcontroller units (MCUs).

AGAIN: Adversarial Training With Attribution Span Enlargement and Hybrid Feature Fusion

1 code implementation CVPR 2023 Shenglin Yin, Kelu Yao, Sheng Shi, Yangzhou Du, Zhen Xiao

To this end, compared with standard DNNs, we discover that the generalization gap of adversarially trained DNNs is caused by the smaller attribution span on the input image.


AnimalTrack: A Benchmark for Multi-Animal Tracking in the Wild

Learning Explicit Credit Assignment for Multi-agent Joint Q-learning

no code implementations29 Sep 2021 Hangyu Mao, Jianye Hao, Dong Li, Jun Wang, Weixun Wang, Xiaotian Hao, Bin Wang, Kun Shao, Zhen Xiao, Wulong Liu

In contrast, we formulate an \emph{explicit} credit assignment problem where each agent gives its suggestion about how to weight individual Q-values to explicitly maximize the joint Q-value, besides guaranteeing the Bellman optimality of the joint Q-value.


Speech-language Pre-training for End-to-end Spoken Language Understanding

no code implementations11 Feb 2021 Yao Qian, Ximo Bian, Yu Shi, Naoyuki Kanda, Leo Shen, Zhen Xiao, Michael Zeng

End-to-end (E2E) spoken language understanding (SLU) can infer semantics directly from speech signal without cascading an automatic speech recognizer (ASR) with a natural language understanding (NLU) module.
