A semidefinite programming approach for robust elliptic localization

no code implementations28 Jan 2024 Wenxin Xiong, Jiajun He, Zhang-Lei Shi, Keyuan Hu, Hing Cheung So, Chi-Sing Leung

This short communication addresses the problem of elliptic localization with outlier measurements, whose occurrences are prevalent in various location-enabled applications and can significantly compromise the positioning performance if not adequately handled.

MF-AED-AEC: Speech Emotion Recognition by Leveraging Multimodal Fusion, ASR Error Detection, and ASR Error Correction

no code implementations24 Jan 2024 Jiajun He, Xiaohan Shi, Xingfeng Li, Tomoki Toda

Therefore, in this paper, we incorporate two auxiliary tasks, ASR error detection (AED) and ASR error correction (AEC), to enhance the semantic coherence of ASR text, and further introduce a novel multi-modal fusion (MF) method to learn shared representations across modalities.

ed-cec: improving rare word recognition using asr postprocessing based on error detection and context-aware error correction

no code implementations8 Oct 2023 Jiajun He, Zekun Yang, Tomoki Toda

Automatic speech recognition (ASR) systems often encounter difficulties in accurately recognizing rare words, leading to errors that can have a negative impact on downstream tasks such as keyword spotting, intent detection, and text summarization.

RECOMBINER: Robust and Enhanced Compression with Bayesian Implicit Neural Representations

1 code implementation29 Sep 2023 Jiajun He, Gergely Flamich, Zongyu Guo, José Miguel Hernández-Lobato

COMpression with Bayesian Implicit NEural Representations (COMBINER) is a recent data compression method that addresses a key inefficiency of previous Implicit Neural Representation (INR)-based approaches: it avoids quantization and enables direct optimization of the rate-distortion performance.

Compression with Bayesian Implicit Neural Representations

1 code implementation NeurIPS 2023 Zongyu Guo, Gergely Flamich, Jiajun He, Zhibo Chen, José Miguel Hernández-Lobato

Many common types of data can be represented as functions that map coordinates to signal values, such as pixel locations to RGB values in the case of an image.
