A Direct Algorithm for the K-Nearest-Neighbor Classifier via Local Warping of the Distance Metric
… is the large model size. There are a number of algorithms that are able to condense the model size of the k-NN classifier at the expense of accuracy. Boosting is therefore desirable for increasing the accuracy of these condensed models. Unfortunately, there does not exist a boosting algorithm …

Global Optimization of Transmitter Placement for Indoor Wireless Communication Systems
The DIRECT (DIviding RECTangles) algorithm JONESJOTi, a variant of Lipschitzian methods for bound constrained global optimization, has been applied to the optimal transmitter placement for indoor wireless systems. Power coverage and BER (bit error rate) are considered as two criteria for optimizing …

Deterministic Parallel Global Parameter Estimation for a Model of the Budding Yeast Cell Cycle
Two parallel deterministic direct search algorithms are combined to find improved parameters for a system of differential equations designed to simulate the cell cycle of budding yeast. Comparing the model simulation results to experimental data is difficult because most of the experimental data is …
