Abstract

Indian folk paintings have a rich mosaic of symbols, colors, textures, and stories making them an invaluable repository of cultural legacy. The paper presents a novel approach to classifying these paintings into distinct art forms and tagging them with their unique salient features. A custom dataset named FolkTalent, comprising 2279 digital images of paintings across 12 different forms, has been prepared using websites that are direct outlets of Indian folk paintings. Tags covering a wide range of attributes like color, theme, artistic style, and patterns are generated using GPT4, and verified by an expert for each painting. Classification is performed employing the RandomForest ensemble technique on fine-tuned Convolutional Neural Network (CNN) models to classify Indian folk paintings, achieving an accuracy of 91.83%. Tagging is accomplished via the prominent fine-tuned CNN-based backbones with a custom classifier attached to its top to perform multi-label image classification. The generated tags offer a deeper insight into the painting, enabling an enhanced search experience based on theme and visual attributes. The proposed hybrid model sets a new benchmark in folk painting classification and tagging, significantly contributing to cataloging India’s folk-art heritage.

Abstract

Empirical investigations demonstrate similar cognitive processing patterns for objects and sexualized women. However, sexual objectification (SO) extends beyond sexualized women. To explore SO, we apply eye-tracking technique in conjunction with local/global and body-inversion paradigms. Ninety-four college students participated in the study. The visual gaze on non-sexualized South-Asian wo(men) images and the response time in Navon task post- priming with upright and inverted images is analyzed. Results indicate that participants of both genders gaze objectify females. Interestingly, male images are also processed as objects and body-inversion effect is observed. A comparison of attention allocation to face versus sexual body parts in upright versus inverted female images shows a reduced face- to-body ratio for the latter orientation, indicating a gender- specific attention shift. Combining the two SO theories, the study objectively substantiates the claim that women undergo objectification in even in non-sexual attire.

Abstract

Investors rely on judgmental heuristics and comparative analysis for future stock price prediction based on specific components of information in hand. Information components are used as anchors for price estimation. Through an eye-tracking experiment, we aim to understand the perceived significance of various formats of information, particularly focusing on graphical and numerical components, and to explore the influence of complex time-varying patterns in stock price line plots. Results show that graphical components capture higher visual attention. Participants are not always loss-averse and prominently exhibit disposition effects for investment decisions in profitable scenarios. The 52-week high is allotted the highest fixation duration, signifying its perception as a strong reference point. Investment choices were found to be varying based on levels of prior knowledge and experience. The visual gaze analysis provides behavioural insights into complex decision-making processes.

Abstract

The number of individuals having identical names on the internet is increasing. Thus making the task of searching for a specific individual tedious. The user must vet through many profiles with identical names to get to the actual individual of interest. The online presence of an individual forms the profile of the individual. We need a solution that helps users by consolidating the profiles of such individuals by retrieving factual information available on the web and providing the same as a single result. We present a novel solution that retrieves web profiles belonging to those bearing identical Full Names through an end-to-end pipeline. Our solution involves information retrieval from the web (extraction), LLM-driven Named Entity Extraction (retrieval), and standardization of facts using Wikipedia, which returns profiles with fourteen multi-valued attributes. After that, profiles that correspond to the same real-world individuals are determined. We accomplish this by identifying similarities among profiles based on the extracted facts using a Prefix Tree inspired data structure (validation) and utilizing ChatGPT's contextual comprehension (revalidation). The system offers varied levels of strictness while consolidating these profiles, namely strict, relaxed, and loose matching. The novelty of our solution lies in the innovative use of GPT -- a highly powerful yet an unpredictable tool, for such a nuanced task. A study involving twenty participants, along with other results, found that one could effectively retrieve information for a specific individual.

Abstract

Functional MRI research using naturalistic stimuli (like movies) can help examine brain networks supporting empathy. Applying graph learning methods to whole-brain time-series signals, we propose a novel fMRI signal processing pipeline that includes high-pass filtering, voxel-level clustering, and windowed graph learning with a sparsity-based approach. The fMRI dataset is from passive viewing of an 8-minute movie shown to 14 healthy volunteers. The emotion rating of the movies by age-matched 40 participants is the ground truth. We considered a total of 54 regions extracted from the AAL Atlas for the study. The sparsity-based graph learning method consistently outperforms in capturing variations in the emotion scale, achieving over 88% match of the graph cluster labels averaged across participants. Temporal analysis reveals a high fit to the emotion scale supported by the method’s effectiveness in capturing dynamic connectomes through graph clustering, indicating the role of contextual inference in building empathy. While the edge-weight dynamics analysis underscores the superiority of sparsity-based learning, the connectome-network analysis highlights the crucial role of the Insula, Amygdala, and Thalamus in empathy, with lateral brain connections facilitating synchronized responses. Spectral filtering analysis by band-pass filter isolated the regions linked to emotional and empathy processing in scenes with high emotional context. We also observe strong similarities between the movies in graph cluster labels, connectome-network analysis, and spectral filtering-based analyses, revealing robust neural correlates of empathy. These findings contribute to a better understanding of the neural dynamics associated with empathy and identify regions specific to empathetic responses to naturalistic stimuli.

Abstract

The proposed work endeavors to support the preservation of tribal arts in their original art form with their unique colors, shapes, and objects. Tribal arts of each region of India is a ‘message’ of their life, traditions, and history, requiring preservation in its pristine, unique form. For example, dotted patterns in Bhil, geometric figures in Warli, dashes in Gond, deities’ expressions in Pichwai paintings, etc., are some notably diverse visual patterns that depict the profound stories of their wholesome culture. In this preliminary work, a dataset is collected by mining the websites, which are direct outlets of tribal arts, thereby ensuring the authenticity of the images included. The collected dataset includes 863 paintings across five different classes of tribal arts viz Warli, Bhil, Gond, Pichwai, and Kalighat, as described in Figure 1. Furthermore, image classification baselines on the collected dataset are developed by fine-tuning the pre-trained ResNet50, InceptionV3, and EfficientNetB0 models. The classification accuracy for the aforementioned baselines is reported in Table 1. Among the baselines, the best testing accuracy of 91.57 % is observed for EfficientNetB0; the confusion matrix for which is shown in Figure 2. The associated F1-scores for this baseline model across all five classes, namely Warli, Bhil, Gond, Pichwai, and Kalighat, were found to be 0.958, 0.882, 0.875, 0.909, and 0.958, respectively which suggests that the dataset is balanced in nature. Furthermore, class activation maps are generated for each image of the collected dataset across all baselines to ascertain the alignment of results generated with the ground truth, which offers a means to comprehend and compare the regions of focus in decision-making. Figure 3 provides an example of a class activation map revealing the salient focus areas, such as human figures represented by triangles and circles in a Warli painting. This analysis can also be used by artists for designing the artwork. The extension of the classification work is to detect counterfeit tribal paintings and quantify the extent of deviation from the original art form, ultimately contributing towards tribal arts preservation and safeguarding their invaluable cultural heritage.

Abstract

The Objectifying Gaze: Impact of Sexualized Media on Viewer Gaze Behavior towards (Non)Traditional Attire Anonymous CogSci submission Abstract In this study, we investigate the priming effect of camera- induced objectifying-gaze, operationalised via sexualised mu- sic video(MV), on university students when looking at tar- get female images in traditional (saree, salwar) and western (shirt-pant, short-dress) attires in the Indian demographics. We showed participants two videos where female leads wore un- revealing Indian attire (saree) and revealing western clothing in sexualised and traditional MVs respectively. We quantified gaze as fixation-duration and visit-count (revisit frequency) metrics. Our findings report that there is a priming effect of sexualised media. Female images in all attires are equally objectified and body-biased gaze is more pronounced in sex- ualised MV priming, short-dress is more objectified in tradi- tional MV priming, and saree is less objectified overall, which confirms the social stereotypes on attire and respectability — traditionally clad (vs. non-traditional) women are seen as more moral and worthy of respect and protection compared to women in hypersexualized and objectified roles.

Abstract

Air pollution due to industrial activity, vehicles, and construction has shown immediate and long-term effects on human health. While respiratory condition manifests directly, long-term conditions like heart diseases, cancer, lung damage, and the impact on fetal health have been established. This study is aimed to explore the effects of air pollution on the physiological health of humans using a smart wearable watch. A total of 8 healthy security guards posted at the institute gate close to a very busy traffic junction for 12 hours a day were recruited. The physiological indicators such as heart rate (HR), body temperature (BT), and SPO2 levels were recorded by the wearable device for changes during the day/night for two seasons (summer and winter). Air pollution monitoring sensors were also deployed at the same site to record PM2.5, PM10, relative humidity (RH), and environmental temperature (ENT). A survey of 43 questions under three different sections: demographic, medical condition, and quality of life (QoL) were also filled by each participant. Descriptive statistics and inferential statistical analysis (Wilcoxon, Correlation) have been presented based on the collected data. The research shows an association between short-term fluctuations in physiological parameters due to air pollution. Still, the findings need to be weighted with the accuracy and consistency of the wearable devices.
