Based on positive experimental results and a meaningful comparison with various versions of KNN, we demonstrated that the improved conventional KNN algorithm can achieve very high positioning accuracy ...

Isolation Forest detects anomalies by isolating observations. It builds binary trees (called iTrees) by recursively ...

Among the many text classification algorithms based on vector space model, the effect of KNN(K-Nearest Neighbor) classifier is outstanding. For KNN classification algorithm, calculating the similarity ...
