We demonstrate that almost all nonparametric dimensionality reduction methods can be expressed by a simple procedure: regularized loss minimization plus singular value truncation. By distinguishing the role of the loss and regularizer in such a process, we recover a factored perspective that reveals some gaps in the current literature. Beyond identifying a useful new loss for manifold unfolding...

To solve the problems of congestion and increased power consumption wheat combine harvesters (WCHs) caused by excessive feed rate, this paper proposes a method to reduce rate decreasing length stalk designs double-cutterbar header (DCH). Using threshing test bench taking stalk, speed tangential rotor as influencing factors conveying time index, influence different parameters on performance was ...
