چکیده

ABSTRACT This paper compares the feedback cancellation performance of different partitioned block frequency-domain adaptive filter (PBFDAF) algorithms. The comparison is made for the error level of the echo canceler of an open and closed loop system of a hearing instrument setup. Special consideration is given to the different transformations and the number of partitions. The results enable a computational efficient design of a hearing instrument for any combination of feedback reduction performance of the predictor and band spacing requirements for the hearing-loss compensator.

Comparison of Classifier Algorithms in the Identification of Polypharmacy and Factors Affecting it in the Elderly Patients

Introduction: Prescribing and consuming drugs more than necessary which is known as polypharmacy, is both waste of resources and harm to patients. Polypharmacy is especially important for elderly patients; therefore, the factors affecting it must be identified and analyzed properly. Method: In this retrospective study, first, several classifier algorithms, i.e., C4.5, SVM, KNN, MLP, and BN for ...
