Data mining tasks Predictive vs descriptive tasks – Predictive tasks: predict the value of a particular attribute (the target variable) based on the values of other attributes – Descriptive tasks: derive patterns (correlations, trends, clusters, trajectories, and anomalies) that summarize the underlying relationships in data Predictive modeling – The goal of predictive modeling is to learn a model that minimizes the error between the predicted and true values of the target variable – Classification: for discrete target variables – Regression: for continuous target variables Cluster analysis – The goal is to find groups of similar observations/objects – Many clustering algorithms have been developed Applications of clustering in biology

The wireless body area network (WBAN) is one of the applications of the Internet of things (IoT) for healthcare, which monitors human physiological parameters. In this paper, a two-objective optimization problem is designed to maximize the sum-throughput and wireless transferred energy simultaneously. The designed one-tier network includes body surface sensors, an implantable sensor, and one coordinator. All of these sensors can harvest energy from the body and radio frequency (RF) signals. A temperature constraint is considered for the implanted sensor due to the sensitivity of internal tissues. Each sensor transmits physiological data to the coordinator in the uplink according to the scheduled time slots obtained by solving the optimization problem. At the beginning of each frame in the downlink, the coordinator transmits a pilot signal to transfer wireless energy and for channel estimation at the sensors. We have used a Recurrent Neural Network (RNN) architecture to predict one time step ahead of the channel. Then by interpolation, the channel gains of all time slots of a frame are estimated and the time scheduling of the sensor access to the channel is improved. The simulation results show that the objective function and time scheduling are improved by the proposed algorithms.
