A Mathematical Model of Dignāga’s Hetu-cakra
A reasoned argument or tarka is essential for a wholesome vāda that aims at establishing the truth. A strong tarka constitutes of a number of elements including an anumāna based on a valid hetu. Several scholars, such as Dharmakīrti, Vasubandhu and Dignāga, have worked on theories for the establishment of a valid hetu to distinguish it from an invalid one. This paper aims to interpret Dignāga’s hetu-cakra, called the wheel of grounds, from a modern philosophical perspective by deconstructing it into a simple probabilistic mathematical model. The objective is to understand how and why a vāda based on a probabilistically weaker hetu can degrade into a Jalpa or vitaṇḍā. To do so, the paper maps the concept of ‘Bounded Rationality’ onto the hetu-cakra. Bounded Rationality, an idea coined by the management thinker Herbert Simon, is often employed in understanding decision-making processes of rational agents. In the context of this paper, the concept would state that the prativādin and ālocaka (debater) may not hold unbounded information to back their pratijñā (proposition). The paper argues that within the probabilistically deconstructed hetu-cakra model, most people argue in the ‘Zone of Bounded Rationality’, and thus, the probability of a debate degrading into Jalpa or vitaṇḍā is high
UBSegNet: Unified Biometric Region of Interest Segmentation Network
Digital human identity management, can now be seen as a social necessity, as
it is essentially required in almost every public sector such as, financial
inclusions, security, banking, social networking e.t.c. Hence, in today's
rampantly emerging world with so many adversarial entities, relying on a single
biometric trait is being too optimistic. In this paper, we have proposed a
novel end-to-end, Unified Biometric ROI Segmentation Network (UBSegNet), for
extracting region of interest from five different biometric traits viz. face,
iris, palm, knuckle and 4-slap fingerprint. The architecture of the proposed
UBSegNet consists of two stages: (i) Trait classification and (ii) Trait
localization. For these stages, we have used a state of the art region based
convolutional neural network (RCNN), comprising of three major parts namely
convolutional layers, region proposal network (RPN) along with classification
and regression heads. The model has been evaluated over various huge publicly
available biometric databases. To the best of our knowledge this is the first
unified architecture proposed, segmenting multiple biometric traits. It has
been tested over around 5000 * 5 = 25,000 images (5000 images per trait) and
produces very good results. Our work on unified biometric segmentation, opens
up the vast opportunities in the field of multiple biometric traits based
authentication systems.Comment: 4th Asian Conference on Pattern Recognition (ACPR 2017
Remaining Useful Life Prediction of Lithium-ion Batteries using Spatio-temporal Multimodal Attention Networks
Lithium-ion batteries are widely used in various applications, including
electric vehicles and renewable energy storage. The prediction of the remaining
useful life (RUL) of batteries is crucial for ensuring reliable and efficient
operation, as well as reducing maintenance costs. However, determining the life
cycle of batteries in real-world scenarios is challenging, and existing methods
have limitations in predicting the number of cycles iteratively. In addition,
existing works often oversimplify the datasets, neglecting important features
of the batteries such as temperature, internal resistance, and material type.
To address these limitations, this paper proposes a two-stage remaining useful
life prediction scheme for Lithium-ion batteries using a spatio-temporal
multimodal attention network (ST-MAN). The proposed model is designed to
iteratively predict the number of cycles required for the battery to reach the
end of its useful life, based on available data. The proposed ST-MAN is to
capture the complex spatio-temporal dependencies in the battery data, including
the features that are often neglected in existing works. Experimental results
demonstrate that the proposed ST-MAN model outperforms existing CNN and
LSTM-based methods, achieving state-of-the-art performance in predicting the
remaining useful life of Li-ion batteries. The proposed method has the
potential to improve the reliability and efficiency of battery operations and
is applicable in various industries, including automotive and renewable energy
Assessment of quality of life of type-2 diabetes mellitus patients in tertiary care teaching hospital in North India
Background: Quality of life (QoL) is a standard indicating a person’s life in better condition as compared to a diseased person or patient. Diabetes itself is not a dangerous disease if managed properly, but it becomes life-threatening after a certain time period because of the patient’s poor interest in disease management and treatment adherence. Diabetes mellitus is an endocrine system disorder that invokes lack of insulin secretion in the bloodstream. The study was conducted to assess the QoL of type-2 diabetes mellitus patients with QoL instrument.Methods: Questionnaire based cross-sectional, prospective study was conducted at Teerthanker Mahaveer Hospital, Moradabad, for a duration of 6 months from January - June 2019, on 196 patients of type-2 diabetes mellitus.Results: On an average 56.5% people have accepted that due to the diabetic condition their working proficiency is decreased. 80.3% of patients have accepted that they were facing problems due to diabetic symptoms. Similarly, 84% of patients have accepted that the ongoing treatment was quite expensive than their expectations. Finally, the last section of the patient’s emotional/mental satisfaction showed that 49.7% of patients were very satisfied with their family support while 13.7% of patients were not satisfied.Conclusions: QOL instrument for Indian diabetes patient’s instrument helped to evaluate the patient’s physical strength, psychological strength of the patient during disease condition, the response provided from the family members and relatives, the economical status of the patient and its effects on their living
Demonstrating the asymmetry of the Indian Ocean Dipole response in regional earth system model of CORDEX-SA
An accurate representation of the Indian Ocean Dipole (IOD) is crucial for the reliable projection of Indian summer monsoon rainfall, making it necessary to improve the understanding of the response of the IOD in the warming climate. For the first time, a high-resolution regional earth system model (RESM) over the CORDEX-SA domain is used to investigate the IOD characteristics. The model performance is evaluated in simulating the IOD and associated mechanism. RESM shows a good resemblance in simulating IOD phases (positive and negative). However, the systematic discrepancy is observed in magnitude. Additionally, RESM well represented the positive IOD's inter-event variability. For example, the stronger event dominated by significant cold anomalies over Sumatra with enhanced westward-extended while a moderate event shows weak cooling confined to the region of Sumatra. Additionally, RESM shows potential to distinguish the ENSO and non-ENSO years with more remarkable skill in representing the spatial pattern of SST over IOD region during non-ESNO years than ENSO years. The RESM realistically simulated the IOD amplitude with greater skill than CMIP5/6 models reported in the earlier studies, indicating reliability towards the projection of the Indian summer monsoon. The weaker IOD-ENSO relationship is caused by producing the more significant number of IOD during non-ENSO years. Despite this reliable fidelity, IOD's slightly earlier peak is driven by the early establishment of low-level equatorial easterly wind. This study provided valuable insight into the IOD's different phases, responsible forcings, and limitations of the RESM in accounting for the role of internal climate variability that can be useful for further improvement in the model physics
