Efficient representation learning for high-dimensional imbalance data

2016

In this paper, a multi-layer weighted extreme learning machine (ML-WELM) is proposed for high-dimensional datasets with class imbalance. The recently proposed single hidden layer WELM method effectively tackles class imbalance but it may not capture …

Magnitude Design of FIR Evidence Filters with Prescribed Transition Rolloff Using Bisection and ICMEE

2018

Evidence filters have found a wide range of applications in military surveillance, environment monitoring, homeland security, etc. Designing evidence filters is challenging because of the nonnegative constraint on its impulse response. A new algorithm is …
