Blockchain in Agri-Food Supply Chains
The involvement of multiple actors in the food industry and the prevalence of centralised systems, which are owned and controlled by single stakeholders, can raise concerns regarding data reliability. When traceability data are stored in centralised systems managed by single entities, they become more susceptible to unintentional errors, deliberate tampering, or potential attacks. Efforts have been made to replace these centralised systems with distributed platforms such as blockchain infrastructure, aimed at fostering trust among supply chain actors.

Encoding Techniques for Gait Analysis
Gait refers to the movement patterns of an individual’s walk. It encompasses the rhythm, speed, and style of movement which require a strong coordination of the upper and lower limbs. The dramatic increase in the use of numerous sensors, e.g., inertial measurement unit (IMU), in our daily wearable devices has gained the interest of the research community to collect kinematic and kinetic data to analyze the gait. The most crucial step for gait analysis is to find the set of appropriate features from continuous time series data to accurately represent human locomotion.

Parallelization Strategies for Graph-Code-Based Similarity Search
The volume of multimedia assets in collections is growing exponentially, and the retrieval of information is becoming more complex. The indexing and retrieval of multimedia content is generally implemented by employing feature graphs. Feature graphs contain semantic information on multimedia assets. Machine learning can produce detailed semantic information on multimedia assets, reflected in a high volume of nodes and edges in the feature graphs. Graph Codes provide fast and effective multimedia indexing and retrieval, even in billion-scale use cases.

Multi-Task Learning, Multi-Branch Networks, and Attention Mechanisms
Diabetic Retinopathy (DR) is one of the most common microvascular complications of diabetes. Diabetic Macular Edema (DME) is a concomitant symptom of DR. As the grade of lesion of DR and DME increases, the possibility of blindness can also increase significantly. To take early interventions as soon as possible to reduce the likelihood of blindness, it is necessary to perform both DR and DME grading.

Applications of TDA to Analyze Cardiovascular Signals
Cardiovascular diseases (CVDs) have been, for a long time, a major global health problem that has caused more deaths than any form of cancer or respiratory disease combined. The detection and prediction of CVDs is made difficult by the numerous etiological factors, complex disease pathways, and diverse clinical presentations. Topological data analysis (TDA) is an approach for analyzing and interpreting complex data sets based on ideas a branch of mathematics called algebraic topology.

An Optimal House Price Prediction Algorithm: XGBoost
An accurate prediction of house prices is a fundamental requirement for various sectors, including real estate and mortgage lending. It is widely recognized that a property’s value is not solely determined by its physical attributes but is significantly influenced by its surrounding neighborhood. Meeting the diverse housing needs of individuals while balancing budget constraints is a primary concern for real estate developers.
