Uncovering Latent Depression Severity for Binary Depression Detection via Advantage-weighting Ranking

Automatic depression detection using audio-visual data faces significant challenges, particularly in disentangling overlapping feature distributions and establishing robust decision boundaries. To address this, we propose a fine-grained multimodal framework featuring a temporal encoder and a mutual transformer to facilitate deep cross-modal fusion.

Enhancing Multimodal Emotion Recognition via Multi-Feature Encoding and Attention-Based Fusion

The paper introduces a multimodal emotion recognition framework that combines audio and visual feature extraction with an attention-based fusion strategy. Audio features include Wav2Vec2 embeddings, MFCCs, and statistical acoustic descriptors, fused via a BiLSTM, while video features are extracted using a ResNet50-BiLSTM architecture. A multi-head attention mechanism fuses these modalities, and experiments on MELD and IEMOCAP show significant accuracy and robustness gains, especially in unbalanced data settings.

MERID: Multimodal Exploration via Recursive Self-Improvement Agents for Major Depression Analysis

MERID is a framework that uses recursive self‑improvement agents to autonomously develop multimodal pipelines for detecting major depressive disorder. It aligns multimodal records with depression targets, jointly modifies representations, fusion, and predictors, and guides revisions through evidence‑guided evolution to validate improvements before inheritance. Experiments on depression benchmarks show MERID outperforms existing multimodal and agent‑based baselines, especially highlighting the importance of acoustic and linguistic cues.

Interpretable Multimodal Classification with Linear Discriminant Tree Ensembles

The paper introduces Linear Discriminant Tree Ensembles (LDT, LDF, LDAB) for multimodal affect and behaviour classification, combining text, audio, and visual streams. It uses tokenization, concept clustering, and tree-based routing to balance accuracy and interpretability, and proposes a modified feature importance metric that reduces negative class bias. The ensembles outperform Multimodal Transformers and Interpretable Multimodal Routing in F1-mod and accuracy, and their feature importance aligns better with human annotations on IEMOCAP and CMU-MOSI datasets.

EviDep: Uncertainty-Aware Multimodal Depression Estimation via Disentangled Evidential Learning

EviDep is a multimodal evidential regression framework for estimating depression severity from audio–visual recordings, incorporating multi‑scale temporal modeling and shared–private representation learning. It uses frequency‑aware feature extraction to decompose behavioral sequences into multiple frequency bands, refined by scale‑specific experts, and applies disentangled evidential learning to separate cross‑modal shared and modality‑specific information. The model outputs Normal‑Inverse‑Gamma distributions via multi‑branch evidential regression, enabling estimation of depression severity along with aleatoric and epistemic uncertainty, and demonstrates competitive accuracy on several benchmark datasets.

Exploring Diffusion Transformers for Cross-Modal Augmentation in Multimodal Brain State Decoding

The paper introduces CoMA-DiT, a bidirectional cross‑modal Diffusion Transformer that uses paired modalities as mutual generative supervision for latent augmentation rather than just inputs for fusion. By conditioning velocity prediction on the paired modality through cross‑modal attention and injecting variation via a reliability‑gated residual mechanism, CoMA‑DiT improves multimodal brain state decoding. Experiments on auditory attention decoding and emotion recognition show consistent gains over 20 baselines, with absolute accuracy and macro‑F1 improvements of 4.28% and 6.70% respectively, and extensive analyses confirm its robustness and interpretability.

Divide and Conquer: Mixture-of-Bottleneck Experts in Informative Ordinal Space for Video-based Multimodal Sentiment Analysis

The paper proposes a Mixture-of-Bottleneck (MoB) framework for video-based multimodal sentiment analysis that treats sentiment as an ordinal regression problem, splitting it into polarity recognition and intensity prediction. MoB assigns modality‑specific latent experts to each sub‑task, learns compact, task‑relevant representations via an information bottleneck, and fuses these experts with a multimodal bottleneck routing module and hard mining strategy. Experiments on four datasets and language models demonstrate that MoB captures fine‑grained intra‑ and inter‑modal dynamics, improving performance and enabling more trustworthy localization of nuanced sentiment signals.

Towards Interpretable Depression Detection: Linking Acoustic Features to DSM-5 Indicators

The paper proposes a transparent framework that links speech acoustic features—such as pitch variability, pauses, and speech tempo—to DSM‑5 indicators of depression, offering interpretable, indicator‑level outputs instead of opaque black‑box models. It runs locally on commodity hardware to preserve privacy and has been preliminarily evaluated on the DAIC‑WOZ dataset, showing consistent associations between acoustic cues and DSM‑5 indicators of psychomotor change and concentration difficulty. Future work aims to validate the approach on longitudinal data and expand multimodal integration while keeping edge constraints.

Reliability-aware Cross-sample Enhancement for Robust Multimodal Sentiment Analysis

Reliability-aware Cross-sample Enhancement (RCE) is a framework for multimodal sentiment analysis that tackles noise and missing modalities by first applying an adaptive variational information bottleneck to compress unreliable modality information. It then retrieves high‑confidence, semantically consistent neighbors from a large candidate pool to enrich current representations, and finally fuses cross‑modal interactions through a multilevel reliability‑aware mechanism. Experiments show RCE consistently outperforms state‑of‑the‑art methods in full, noisy, and missing‑modality scenarios.
