Spatial understanding is a critical capability for LVLMs (Large Vision-Language Models) to advance embodied AI applications. Existing works primarily focus on enhancing spatial understanding within a single frame, i.e., injecting 3D spatial concepts into LVLMs under single coordinate system. However
With the advancement of Vision-Language Models (VLMs), employing VLM-as-a-Judge for visual evaluation has become a widely adopted metric in vision research. However, existing VLM-as-a-Judge approaches suffer from biased scoring outcomes with low discrimination and lack the capacity for unified multi
Merging multiple low-rank adapters (LoRA) provides a practical route to scaling multi-task learning and deployment more efficiently than full-model weight merging, while avoiding reliance on task-specific training data. However, most existing approaches either treat LoRA updates as dense weight delt…
Open-Vocabulary Multi-Object Tracking (OV-MOT) aims to enable approaches to track objects without being limited to a predefined set of categories. Current OV-MOT methods typically rely primarily on instance-level detection and association, often overlooking trajectory information that is unique and…
To enhance the robustness and accuracy of the small model, existing approaches combine adversarial training with knowledge distillation, introducing a comprehensive single-teacher model to improve the performance of the student model (small model). However, due to the limited knowledge of a teacher…
Low-Rank Adaptation (LoRA) is a parameter-efficient fine-tuning approach that adaptes pre-trained Large Language Models (LLMs) to multi-tenant tasks by generating a variety of LoRA adapters. However, this approach faces significant security challenges and is particularly susceptible to malicious ser…
Language-Visual Large Models (LVLMs) have made significant strides in enhancing visual understanding capabilities. However, these models often struggle with knowledge-based visual tasks due to constrains in their pre-training data scope and timeliness. Existing Retrieval-Augmented Generation (RAG) m
Ransomware attacks pose significant threats and have caused substantial economic losses across various industries worldwide. Existing defense mechanisms typically focus on detecting ransomware in environments free from interference by other legitimate programs. However, in real-world applications, r…
LLM-based agents can greatly extend the abilities of LLMs and thus attract sharply increased studies. An ambitious vision – serving users by manipulating massive API-based tools – has been proposed and explored. However, we find a widely accepted evaluation mechanism for generic agents is still miss…
The vulnerability of deep neural networks poses a significant challenge to their application in security-sensitive domains. In this paper, we propose the Search Robust and Adaptable Architecture (SRAA) to identify the robust architecture. Unlike previous NAS-based approaches that utilize a single ne…
Automatic speech verification (ASV) authenticates individuals based on distinct vocal patterns, playing a pivotal role in many applications such as voice-based unlocking systems for devices. The ASV system comprises three stages: training, registration, and validation. The model refines using voice…
Speaker verification has been widely and successfully adopted in many mission-critical fields for user identification. Similar to other classical machine learning tasks, the training performance of speaker verification relies heavily on the number and diversity of data. Therefore third-party data (e…
With growing concerns regarding privacy in machine learning models, regulations have committed to granting individuals the right to be forgotten while mandating companies to develop non-discriminatory machine learning systems, thereby fueling the study of the machine unlearning problem. Our attentio…
We investigate the statistical and computational requirements for distributed kernel ridge regression with randomized sketching (DKRR-RS) and successfully achieve the optimal learning rates with only a fraction of computations. More precisely, the proposed DKRR-RS combines sparse randomized sketchin…
Kernel $k$-means is arguably one of the most common approaches to clustering. In this paper, we investigate the efficiency of kernel $k$-means combined with randomized sketches in terms of both statistical analysis and computational requirements. More precisely, we propose a unified randomized sketc…
We study the statistical performance for distributed kernel ridge regression with Nyström (DKRR-NY) and with Nyström and iterative solvers (DKRR-NY-PCG) and successfully derive the optimal learning rates, which can improve the ranges of the number of local processors $p$ to the optimal in existing s…
