Parkinson's disease (PD) is a neurodegenerative disease affecting millions of people around the world. Conventional PD detection algorithms are generally based on first and second-generation artificial neural network (ANN) models which consume high energy and have complex architecture. Considering these limitations, a time-varying synaptic efficacy function based leaky-integrate and fire neuron model, called SEFRON is used for the detection of PD.

Article Synopsis
  • Breast cancer is the second most common cancer in women, with invasive ductal breast cancer being the most lethal.
  • The study evaluates three deep learning models—Vision Transformer (ViT), Convmixer, and VGG-19—using a breast cancer histopathological image database to detect and classify tumors.
  • ViT outperformed the other models with an impressive accuracy of 99.89% for binary classification, suggesting it could improve early diagnosis and treatment of breast cancer while potentially being applicable to other diseases.

Article Synopsis
  • Parkinson's disease (PD) is tough to diagnose early, but medical imaging tools like MRI and SPECT help gather measurable brain health data non-invasively.
  • This study introduces four deep learning models, enhanced by a hybrid model and grey wolf optimization (GWO) to better detect PD using standard datasets.
  • The hybrid model GWO-VGG16 + InceptionV3 showed the best results, achieving up to 99.94% accuracy with T1, T2-weighted datasets and 100% accuracy with SPECT DaTscan datasets.

In this paper, NeuralProphet (NP), an explainable hybrid modular framework, enhances the forecasting performance of pandemics by adding two neural network modules; auto-regressor (AR) and lagged-regressor (LR). An advanced deep auto-regressor neural network (Deep-AR-Net) model is employed to implement these two modules. The enhanced NP is optimized via AdamW and Huber loss function to perform multivariate multi-step forecasting contrast to Prophet.

Thyroid cancer is a life-threatening condition that arises from the cells of the thyroid gland located in the neck's frontal region just below the adam's apple. While it is not as prevalent as other types of cancer, it ranks prominently among the commonly observed cancers affecting the endocrine system. Machine learning has emerged as a valuable medical diagnostics tool specifically for detecting thyroid abnormalities.

Accurate diagnosis of Parkinson's disease (PD) at an early stage is challenging for clinicians as its progression is very slow. Currently many machine learning and deep learning approaches are used for detection of PD and they are popular too. This study proposes four deep learning models and a hybrid model for the early detection of PD.

Computer-assisted diagnostic systems have been developed to aid doctors in diagnosing thyroid-related abnormalities. The aim of this research is to improve the diagnosis accuracy of thyroid abnormality detection models that can be utilized to alleviate undue pressure on healthcare professionals. In this research, we proposed deep learning, metaheuristics, and a MCDM algorithms-based framework to detect thyroid-related abnormalities from ultrasound and histopathological images.

Covid-19 disease caused by novel coronavirus (SARS-CoV-2) is a highly contagious epidemic that originated in Wuhan, Hubei Province of China in late December 2019. World Health Organization (WHO) declared Covid-19 as a pandemic on 12th March 2020. Researchers and policy makers are designing strategies to control the pandemic in order to minimize its impact on human health and economy round the clock.
