Feature selection is used in many application areas relevant to expert and intelligent systems, such as data mining machine learning, image processing, anomaly detection, bioinformatics natural language processing. based on information theory a popular approach due its computational efficiency, scalability terms of the dataset dimensionality, independence from classifier. Common drawbacks this are lack about interaction between features classifier, redundant irrelevant features. The latter...

Activity recognition using wearable sensors has become essential for a variety of applications. Tri-axial accelerometers are the most widely used sensor activity recognition. Although various features have been to capture patterns and classify accelerometer signals recognise activities, there is no consensus on best choose. Reducing number can reduce computational cost complexity enhance performance classifiers. This paper identifies signal that significant discriminative power between...

Dementia is a syndrome caused by chronic or progressive disease of the brain, which affects memory, orientation, thinking, calculation, learning ability and language. The Clock Drawing Test (CDT) Mini Mental State Examination (MMSE) are well-known cognitive assessment tests. A known obstacle to wider usage CDT assessments scoring interpretation results. This paper introduces novel cascade classifier, can help in diagnosis three stages dementia. data used this research 604 clock drawings...

The global population is ageing, leading to shifts in healthcare needs. Home monitoring systems currently focus on physical health, but there an increasing recognition that psychological wellbeing also needs support. This raises the question of how design devices older adults can interact with log their feelings. We designed three tangible prototypes, based existing paper-based scales affect. report findings from a lab study which participants used prototypes emotion standardised emotional...

Loneliness is a significant well-being issue that affects older adults. Existing, commonly used social connection platforms do not contain facilities to break the cognitive cycle of loneliness, and loneliness interventions implemented without due processes could have detrimental effects on well-being. There also lack digital technology designed with adults.We aimed iteratively design user-centered smartphone app can address in The aim this study was investigate loneliness-related...

Background Movement analysis in a clinical setting is frequently restricted to observational methods inform decision making, which has limited accuracy. Fixed-site, optical, expensive movement laboratories provide gold standard kinematic measurements; however, they are rarely accessed for routine use. Wearable inertial measurement units (IMUs) have been demonstrated as comparable, inexpensive, and portable toolkits. MoJoXlab therefore developed work with generic wearable IMUs. However,...

The Clock Drawing Test is one of the most widely used screening tools for cognitive impairment and dementia. Since its introduction, more than fifteen scoring systems have been developed to assess clock drawings. However, very little research has conducted study significance elements (features) drawings correct diagnosis This paper employs a feature selection method called Feature Interaction Maximization (FIM) identify significant visual features test, which can be associated with proposed...

The world is facing an ageing population phenomenon, coupled with health and social problems, which affect older people's ability to live independently. This situation challenges the viability of services. Smart home technology can play a significant role in easing pressure on caregivers, as well reduce financial costs Activity Daily Living (ADL) recognition essential step translate sensor data into activities at high semantic levels. Supervised Machine Learning (ML) algorithms are most...

Older adults at home frequently rely on 'circles of support' which range from relatives and neighbours, to the voluntary sector, social workers, paid carers, medical professionals. Creating, maintaining, coordinating these circles support has often been done manually in an ad hoc manner. We argue that a socio-technical system assists creating, is key enabler community healthcare for older adults.

The COVID-19 pandemic is worsening loneliness for many older people through the challenges it poses in engaging with their social worlds. Digital technology has been offered as a potential aid, however, popular digital tools have not designed to address needs of adults during times limited contact. We propose that Social Identity Model Change (SIMIC) could be foundation interventions. While SIMIC well-established approach maintaining wellbeing life transitions, rigorously applied There are...
