Synergistic Prompting for Robust Visual Recognition with Missing Modalities

ICCV 2025poster

Large-scale multi-modal models have demonstrated remarkable performance across various visual recognition tasks by leveraging extensive paired multi-modal training data. However, in real-world applications, the presence of missing or incomplete modality inputs often leads to significant performance…

VQA-Augmented Machine Translation with Cross-Modal Contrastive Learning

EMNLP 2025

Multimodal machine translation (MMT) aims to enhance translation quality by integrating visual information. However, existing methods often extract visual features using pre-trained models while learning text features from scratch, leading to representation imbalance. These methods are also prone to

Correctable-DST: Mitigating Historical Context Mismatch between Training and Inference for Improved Dialogue State Tracking

EMNLP 2022main

Recently proposed dialogue state tracking (DST) approaches predict the dialogue state of a target turn sequentially based on the previous dialogue state. During the training time, the ground-truth previous dialogue state is utilized as the historical context. However, only the previously predicted d…

Neural Noise Embedding for End-To-End Speech Enhancement with Conditional Layer Normalization

ICASSP 2021accepted

Most of the deep learning based speech enhancement methods focus on the modeling of complicated relationship between the noisy speech and the clean speech without the consideration of noise information. In order to cope with various complex noise scenes, we introduce a novel enhancement architecture…

Principal component analysis in the stochastic differential privacy model

UAI 2021poster

In this paper, we study the differentially private Principal Component Analysis (PCA) problem in stochastic optimization settings. We first propose a new stochastic gradient perturbation PCA mechanism (DP-SPCA) for the calculation of the right singular subspace to achieve $(\epsilon,\delta)$-differe…

A Time-Frequency Network with Channel Attention and Non-Local Modules for Artificial Bandwidth Extension

ICASSP 2020accepted

Convolution neural networks (CNNs) have been achieving increasing attention for the artificial bandwidth extension (ABE) task recently. However, these methods use the flipped low-frequency phase to reconstruct speech signals, which may lead to the well-known invalid short-time Fourier Transform (STF…
