Traditional methods cannot effectively diagnose tumor since they are based on the assumption of well-balanced dataset.. However, a hybrid method can help to alleviate the two-class imbalance problem existing in the ...

We analyze the convergence rates of $k$ nearest neighbor density estimation method, under notation="LaTeX">$\ell _{\alpha} $ norm with notation="LaTeX">$\alpha \in [1,\infty]$ . Our analysis includes two different cases depending on w...

—This paper describes our efforts in refining k-nearest neighbor forest attributes classification using U.S. Department of Agriculture Forest Service Forest Inventory and Analysis plot data and Landsat 7 Enhanced Thematic Mapper Plus imagery. The analysis focuses on FIA-defined forest type classification across St. Louis County in northeastern Minnesota. We outline three steps in the classifica...
