Multimodal visual language models are gaining prominence in open-world applications, driven by advancements model architectures, training techniques, and high-quality data. However, their performance is often limited insufficient task-specific data, leading to poor generalization biased outputs. Existing efforts increase task diversity fine-tuning datasets hindered the labor-intensive process of manual labeling, which typically produces only a few hundred types. To address this, we propose...
Enhancing the fine-grained instance spatiotemporal motion perception capabilities of Video Large Language Models is crucial for improving their temporal and general video understanding. However, current models struggle to perceive detailed complex motions. To address these challenges, we have made improvements from both data model perspectives. In terms data, meticulously curated iMOVE-IT, first large-scale instance-motion-aware instruction-tuning dataset. This dataset enriched with...
To identify network bottlenecks of urban expressway effectively is a foundational work for improving traffic condition and preventing congestion. This study proposes methodology to estimate the impact incident on basis modified cell transmission model. The metastable state was taken into account in proposed method reflect actual operating flow as much possible. Regarding location incident, restructuring settings discussed. We then proceed introduce new concept effected length given time...
Since the “Belt and Road” Initiative, air transport has become second largest mode of after ocean shipping contributed more to international trade between countries. To explore hierarchical characteristics aviation network Road,” analyze relationship levels, identify core layer network, k ‐core analysis based on “degree” value was designed performed; data airports routes were collected construct model; then, decomposition conducted reduce size nodes by from outside inside, a structure model...
In the field of multi-modal language models, majority methods are built on an architecture similar to LLaVA. These models use a single-layer ViT feature as visual prompt, directly feeding it into alongside textual tokens. However, when dealing with long sequences signals or inputs such videos, self-attention mechanism can lead significant computational overhead. Additionally, using features makes challenging for large perceive fully. This paper proposes efficient model minimize costs while...
Driving safety is considered to have a strong relationship with traffic flow characteristics. However, very few studies addressed the impacts in three-phase theory that has been demonstrated be an advancement explaining empirical features of flow. Another important issue affecting driver experience heterogeneity, especially developing countries experiencing dramatic growth number novice drivers. Thus, primary objective current study develop microsimulation environment for evaluating...
Air transport has broad development potential along the “ Belt and Road” by owing to its fast, direct, comfortable advantages, community structure is an important factor determining efficiency service functions of aviation network. The detection analysis “Belt network would help understand internal relationship spatial better integrated optimized Based on data international routes between 522 airports in 2019, this paper establishes model calculates degree, average path, clustering...
