Analyzing the Training Dynamics of Image Restoration Transformers: A Revisit to Layer Normalization

ICLR 2026poster

This work analyzes the training dynamics of Image Restoration (IR) Transformers and uncovers a critical yet overlooked issue: conventional LayerNorm (LN) drives feature magnitudes to diverge to a million scale and collapses channel-wise entropy. We analyze this in the perspective of networks attempt…

Ambiguity-Restrained Text-Video Representation Learning for Partially Relevant Video Retrieval

AAAI 2025technical

Partially Relevant Video Retrieval~(PRVR) aims to retrieve a video where a specific segment is relevant to a given text query. Typical training processes of PRVR assume a one-to-one relationship where each text query is relevant to only one video. However, we point out the inherent ambiguity between…

Auto-Encoded Supervision for Perceptual Image Super-Resolution

CVPR 2025poster

This work tackles the fidelity objective in the perceptual super-resolution (SR) task. Specifically, we address the shortcomings of pixel-level \mathcal L _\text p loss (\mathcal L _\text pix ) in the GAN-based SR framework. Since \mathcal L _\text pix is known to have a trade-off relationship aga…

Bridging the Semantic Granularity Gap Between Text and Frame Representations for Partially Relevant Video Retrieval

AAAI 2025technical

Partially Relevant Video Retrieval (PRVR) addresses the challenges of text-to-video retrieval in real-world scenarios where untrimmed videos are prevalent. Traditional PRVR methods encode videos at two feature scales: (1) frame-level to capture fine details, and (2) clip-level to recognize broader c…

Mitigating Semantic Collapse in Partially Relevant Video Retrieval

NeurIPS 2025poster

Partially Relevant Video Retrieval (PRVR) seeks videos where only part of the content matches a text query. Existing methods treat every annotated text–video pair as a positive and all others as negatives, ignoring the rich semantic variation both within a single video and across different videos.…

Prototypes are Balanced Units for Efficient and Effective Partially Relevant Video Retrieval

ICCV 2025poster

In a retrieval system, simultaneously achieving search accuracy and efficiency is inherently challenging. This challenge is particularly pronounced in partially relevant video retrieval (PRVR), where incorporating more diverse context representations at varying temporal scales for each video enhance…
