Brain–Behavior Alignment and Cross-Modal Contrastive Learning for Multimodal Autism Spectrum Disorder Detection

This paper proposes the Brain–Behavior Alignment Network with Cross-Modal Contrastive Learning Transformer (BBAN-CMCLT), a novel multimodal deep learning model that integrates fMRI, facial, eye-tracking, and clinical data to achieve state-of-the-art accuracy (98.97%) in detecting Autism Spectrum Disorder by effectively aligning brain and behavioral patterns.

Difficulty-Aware Sample Allocation for Adaptive Data Augmentation in Semantic Segmentation

This paper introduces Difficulty-Aware Sample Allocation (DASA), an architecture-agnostic framework that enhances semantic segmentation performance by dynamically assigning stronger data augmentation to samples based on a multi-factor difficulty score combining prediction ambiguity, training loss, class rarity, and boundary complexity.

Detecting Cross-Medium Stylistic Signals in Sketches and Paintings with Pretrained Visual Encoders

This study demonstrates that pretrained visual encoders like CLIP and SigLIP can detect persistent stylistic signals across sketches and paintings better than handcrafted descriptors, yet their fragility against visually similar negatives suggests they are more valuable as tools for analyzing AI's perception of artistic style than as reliable authentication mechanisms.

Cross-Layer Early Detection of SDN-IOT Attacks: Fusing Controller Telemetry With Data-Plane Flow Statistics

This paper proposes a dual-branch late fusion model that integrates ONOS controller telemetry with data-plane flow statistics using the ASEADOS-SDN-IoT benchmark, achieving high detection accuracy while significantly reducing the packet count required for early attack identification compared to data-plane-only baselines.
