Erase to Improve: Erasable Reinforcement Learning for Search-Augmented LLMs

ICLR 2026poster

While search-augmented large language models (LLMs) exhibit impressive capabilities, their reliability in complex multi-hop reasoning remains limited. This limitation arises from three fundamental challenges: decomposition errors, where tasks are incorrectly broken down; retrieval missing, where key…

Language-based Trial and Error Falls Behind in the Era of Experience

ICML 2026poster

While Large Language Models (LLMs) excel in language-based agentic tasks, their applicability to unseen, nonlinguistic environments (e.g., symbolic or spatial tasks) remains limited. Previous work attributes this performance gap to the mismatch between the pretraining distribution and the testing di…

StepSearch: Igniting LLMs Search Ability via Step-Wise Proximal Policy Optimization

EMNLP 2025

Efficient multi-hop reasoning requires Large Language Models (LLMs) based agents to acquire high-value external knowledge iteratively. Previous work has explored reinforcement learning (RL) to train LLMs to perform search-based document retrieval, achieving notable improvements in QA performance, bu

ICD-Face: Intra-class Compactness Distillation for Face Recognition

ICCV 2023poster

Knowledge distillation is an effective model compression method to improve the performance of a lightweight student model by transferring the knowledge of a well-performed teacher model, which has been widely adopted in many computer vision tasks, including face recognition (FR). The current FR dist…

Improving Robust Fariness via Balance Adversarial Training

AAAI 2023technical

Adversarial training (AT) methods are effective against adversarial attacks, yet they introduce severe disparity of accuracy and robustness between different classes, known as the robust fairness problem. Previously proposed Fair Robust Learning (FRL) adaptively reweights different classes to improv…

AnchorFace: Boosting TAR@FAR for Practical Face Recognition

AAAI 2022technical

Within the field of face recognition (FR), it is widely accepted that the key objective is to optimize the entire feature space in the training process and acquire robust feature representations. However, most real-world FR systems tend to operate at a pre-defined False Accept Rate (FAR), and the co…

DTG-SSOD: Dense Teacher Guidance for Semi-Supervised Object Detection

NeurIPS 2022accept

The Mean-Teacher (MT) scheme is widely adopted in semi-supervised object detection (SSOD). In MT, sparse pseudo labels, offered by the final predictions of the teacher (e.g., after Non Maximum Suppression (NMS) post-processing), are adopted for the dense supervision for the student via hand-crafted…

Knowledge Distillation for Object Detection via Rank Mimicking and Prediction-Guided Feature Imitation

AAAI 2022technical

Knowledge Distillation (KD) is a widely-used technology to inherit information from cumbersome teacher models to compact student models, consequently realizing model compression and acceleration. Compared with image classification, object detection is a more complex task, and designing specific KD m…

PseCo: Pseudo Labeling and Consistency Training for Semi-Supervised Object Detection

ECCV 2022poster

"In this paper, we delve into two key techniques in Semi-Supervised Object Detection (SSOD), namely pseudo labeling and consistency training. We observe that these two techniques currently neglect some important properties of object detection, hindering efficient learning on unlabeled data. Specific…

Differentiable Optimization of Generalized Nondecomposable Functions using Linear Programs

NeurIPS 2021poster

We propose a framework which makes it feasible to directly train deep neural networks with respect to popular families of task-specific non-decomposable performance measures such as AUC, multi-class AUC, $F$-measure and others. A common feature of the optimization model that emerges from these tasks…

Rotation Consistent Margin Loss for Efficient Low-Bit Face Recognition

CVPR 2020poster

In this paper, we consider the low-bit quantization problem of face recognition (FR) under the open-set protocol. Different from well explored low-bit quantization on closed-set image classification task, the open-set task is more sensitive to quantization errors (QEs). We redefine the QEs in angula…

Knowledge Distillation via Route Constrained Optimization

ICCV 2019oral

Distillation-based learning boosts the performance of the miniaturized neural network based on the hypothesis that the representation of a teacher model can be used as structured and relatively weak supervision, and thus would be easily learned by a miniaturized model. However, we find that the repr…
