Semi-Supervised Domain Generalization for Object Detection via Language-Guided Feature Alignment
Existing domain adaptation (DA) and generalization (DG) methods in object
detection enforce feature alignment in the visual space but face challenges
like object appearance variability and scene complexity, which make it
difficult to distinguish between objects and achieve accurate detection. In
this paper, we are the first to address the problem of semi-supervised domain
generalization by exploring vision-language pre-training and enforcing feature
alignment through the language space. We employ a novel Cross-Domain
Descriptive Multi-Scale Learning (CDDMSL) aiming to maximize the agreement
between descriptions of an image presented with different domain-specific
characteristics in the embedding space. CDDMSL significantly outperforms
existing methods, achieving 11.7% and 7.5% improvement in DG and DA settings,
respectively. Comprehensive analysis and ablation studies confirm the
effectiveness of our method, positioning CDDMSL as a promising approach for
domain generalization in object detection tasks.Comment: Accepted at BMVC 202
Prevalence of Dementia Among Older Patients: A Hospital-Based Study in Iran
Background: Dementia constitutes a public health hazard in developing countries. The aim of this study was to evaluate the prevalence of dementia and its associated factors in older hospitalized patients. Methods: The participants of this cross-sectional study consisted of older patients admitted to medical wards in Rasoul-e Akram hospital in Tehran, Iran. Mini-Mental State Examination, Mini-Cog test, Geriatric Depression Scale, Activities of Daily Living-Instrumental Activities of Daily Living (ADL-IADL) scale, and socioeconomic questionnaires were used. Results: A total of 205 elderly inpatients were included. The mean age was 71.33 ± 7.35 years; 63.4 of the participants had normal cognitive function, while 36.6 had some degree of cognitive impairment. There was a statistically significant relationship between gender, age, number of children, and occupation and the prevalence of dementia. Conclusion: Appropriate cognitive screening of older patients upon admission to hospitals could help identify potential adverse events and enhance the quality of care for patients with comorbid dementia. © The Author(s) 2019
