10.48550/arXiv.2603.26088A novel framework for adaptive knowledge distillation in computer vision that improves student model efficiency by learning to reweight instance importance during training.
Abstract
As deep vision models grow increasingly complex to achieve higher performance, deployment efficiency has become a critical concern. Knowledge distillation (KD) mitigates this issue by transferring knowledge from large teacher models to compact student models. While many feature-based KD methods rely on spatial filtering to guide distillation, they typically treat all object instances uniformly, ignoring instance-level variability. Moreover, existing attention filtering mechanisms are typically heuristic or teacher-driven, rather than learned with the student. To address these limitations, we propose Learnable Instance Attention Filtering for Adaptive Detector Distillation (LIAF-KD), a novel framework that introduces learnable instance selectors to dynamically evaluate and reweight instance importance during distillation. Notably, the student contributes to this process based on its evolving learning state. Experiments on the KITTI and COCO datasets demonstrate consistent improvements, with a 2% gain on a GFL ResNet-50 student without added complexity, outperforming state-of-the-art methods.

WHY NOW
Computer Vision moved forward this cycle; last verified April 2026. Public score 7.0/10. Production flags indicate code availability.
we propose Learnable Instance Attention Filtering for Adaptive Detector Distillation (LIAF-KD), a novel framework that introduces learnable instance selectors to dynamically evaluate and reweight instance importance during distillation.
This is a core methodological contribution explicitly stated in the abstract and conclusion.

Notably, the student contributes to this process based on its evolving learning state.
This is a key feature of the proposed method, explicitly mentioned in the abstract and conclusion.
partial
Experiments on the KITTI and COCO datasets demonstrate consistent improvements, with a 2% gain on a GFL ResNet-50 student without added complexity, outperforming state-of-the-art methods.
This is a specific quantitative result reported in the abstract and supported by Table 1.

Experiments on the KITTI and COCO datasets demonstrate consistent improvements, with a 2% gain on a GFL ResNet-50 student without added complexity, outperforming state-of-the-art methods.
The abstract states this, and Table 1 provides comparative results showing LIAF-KD outperforming other methods.
partial
In contrast, LIAF-KD achieves more accurate object localization and classification.
This is a qualitative result supported by the visual comparison in Figure 2.
partial
Moreover, existing attention filtering mechanisms are typically heuristic or teacher-driven, rather than learned with the student.
This is presented as a limitation of prior work, motivating the proposed method, and is explicitly stated in the abstract.
partial
The proposed method consistently outperforms student baselines and several state-of-the-art KD approaches while maintaining a favorable complexity–accuracy trade-off, highlighting its potential for real-time and resource-constrained applications.
This is a key benefit and implication of the method, stated in the conclusion.
