Abstract

A large number of multi-attribute group decisionmaking (MAGDM) have been widely introduced to obtain consensus results. However, most of the methodologies ignore the conflict among the experts opinions and only consider equal or variable priorities of them. Therefore, this study aims to propose an Evidential MAGDM method by assessing the inter-observational variability and handling uncertainty that emerges between the experts. The proposed framework has fourfold contributions. First, the basic probability assignment (BPA) generation method is introduced to consider the inherent characteristics of each alternative by computing the degree of belief. Second, the ordered weighted belief and plausibility measure is constructed to capture the overall intrinsic information of the alternative by assessing the inter-observational variability and addressing the conflicts emerging between the group of experts. An ordered weighted belief divergence measure is constructed to acquire the weighted support for each group of experts to obtain the final preference relationship. Finally, we have shown an illustrative example of the proposed Evidential MAGDM framework. Further, we have analyzed the interpretation of Evidential MAGDM in the real-world application for ensemble classifier feature fusion to diagnose retinal disorders using optical coherence tomography images.

Abstract

Automatic diagnosis techniques have evolved to identify age-related macular degeneration (AMD) by employing single modality Fundus images or optical coherence tomography (OCT). To classify ocular diseases, fundus and OCT images are the most crucial imaging modalities used in the clinical setting. Most deep learning-based techniques are established on a single imaging modality, which contemplates the ocular disorders to a specific extent and disregards other modality that comprises exhaustive information among distinct imaging modalities. This paper proposes a modality-specific multiscale color space embedding integrated with the attention mechanism based on transfer learning for classification (MCGAEc), which can efficiently extract the distinct modality information at various scales using the distinct color spaces. In this work, we first introduce the modality-specific multiscale color space encoder model, which includes diverse feature representations by integrating distinct characteristic color spaces on a multiscale into a unified framework. The extracted features from the prior encoder module are incorporated with the attention mechanism to extract the global features representation, which is integrated with the prior extracted features and transferred to the random forest classifier for the classification of AMD. To analyze the performance of the proposed MCGAEc method, a publicly available multi-modality dataset from Project Macula for AMD is utilized and compared with the existing models., Comment: 27th International Conference on Pattern Recognition (ICPR) 2024

35. Domesticating technology: Learning from the use of mobile phone of small women rural entrepreneurs in India during COVID-19

Author

Chakraborty, Debjani and Garg, Chhavi

Abstract

The COVID-19 pandemic and the worldwide lockdowns that followed the same have led to drastic changes in our lifestyles. While the lockdowns marked a global transition to a world of online services and products, the change was neither easy nor smooth for many. From lack of access to technology to the absence of skills to use it, the act of “going digital” was littered with challenges for people across the world. In the South-Asian country of India, this lack of access was further amplified by the presence of a gender digital divide. Among the women from various factions of the society, one such category affected by it was female entrepreneurs from small rural areas in India. These entrepreneurs were cut off from their clientele owing to a nationwide lockdown in the country imposed to curb the spread of COVID-19. Most of these women had no prior experience with technology (which is mobile phones in their case) but they not only negotiated access but used it to sustain and grow their entrepreneurial endeavors in a short duration of time. This study, through in-depth qualitative interviews with female entrepreneurs from small rural areas in India maps their usage patterns and their negotiations for domesticating mobile phones. The research found that the first two stages of domestication theory (appropriation and objectification) were easier to navigate for the women entrepreneurs, but gender expectations from them made the last two stages of incorporation and conversion challenging.
