GeHirNet: A Sex-Aware Hierarchical Model for Fair and Accurate Voice Pathology Classification
Item type: Conference Paper
Wu F.; Zhao K.; Fleisch E.; et al. (2026)
AI-based voice analysis shows promise as a noninvasive tool for disease diagnostics, yet existing systems often fail to generalize due to sex-related acoustic differences and scarce data for rare pathologies. We propose a clinically motivated two-stage framework that first captures sex-specific vocal representations using ResNet-50 on Mel spectrograms, followed by sex-conditioned disease classification. We address class imbalance through multi-scale resampling and time-warping augmentation. Evaluated on a merged dataset from four public repositories, our framework achieves state-of-the-art performance, attaining 97.2% accuracy and 94.5% MCC on average, consistently outperforming a single-stage baseline with an average MCC improvement of approximately 3%. Fairness evaluation shows reduced sex-based performance gaps, while feature representations reveal sex-specific patterns that provide clinical evidence supporting a hierarchical, sex-aware design. Together, these results demonstrate that sex-aware hierarchical modeling improves both classification accuracy and fairness in voice pathology detection, with potential applications in telemedicine and clinical decision support.
Encounters, Affective Anecdotes, and the Archive: Traveling with Emilie von Berlepsch to Scotland
Item type: Journal Article
Rieger E. (2026)
This article explores a feminist, embodied approach to architectural historiography through a reenactment of Emilie von Berlepsch’s (1755-1830) travels to Scotland in 1799-1800. In 2023, I retraced part of her route and reread selected passages aloud on site, treating both her historical encounter and my contemporary one as architectural evidence. Focusing on St. Martin’s Abbey near Perth, where Berlepsch stayed for a period, the article weaves historical analysis with personal, creative writing, which I call affective anecdotes. These anecdotes register frictions, breakdowns, and failed attempts to ‘follow’ her footsteps that shaped my encounters with sites and archives. They function as protocols of affects that conventional, rigorous academic writing cannot accommodate, and, in doing so, they call into question the conditions under which architectural knowledge is produced. I argue that Berlepsch’s travel writing offers a situated architectural critique grounded in routine, movement, and use, evaluating domestic space through the daily routes it demands and through the gendered and classed spatial organization. By placing Berlepsch’s eighteenth-century critique alongside my own embodied encounters, the article interrogates the persistent assumption of the disembodied researcher in architectural historiography. Discomfort functions as an analytic and methodological lens across both temporalities, not to collapse them, but to make visible the asymmetries of access, expectation, and epistemic authority and to rethink how architectural histories are written.
