One important classifier ensemble for multiclass classification problems is error-correcting output codes (ECOCs). It bridges multiclass problems and binary-class classifiers by decomposing multiclass problems to a serial binary-class problems. In this paper, we present a heuristic ternary code, named weight optimization and layered clustering-based ECOC (WOLC-ECOC). It starts with an arbitrary valid...
In this paper, new fountain codes named LT-LR-DRS (Luby Transfer with Loss Rate and Decreasing Ripple Size) codes are proposed for wireless relay communications. The transmission is divided into two phases: at first phase, all original symbols are transmitted and some original symbols are lost during transmission; encoded symbols generated by LT-LR-DRS codes are transmitted at second phase to recover...
A common method to solve a multiclass classification problem is to reduce the problem to a serial binary classification problems and combine them via Error-Correcting Output Codes (ECOC). The ECOC contains three parts: coding design, decoding algorithm, and base dichotomizer. Recently, the Loss-Weighted (LW) decoding algorithm (Escalera et al., PAMI2010), which introduces a weight matrix to the Loss-Based...
