WebThe direction parameter controls whether forward or backward SFS is used. In general, forward and backward selection do not yield equivalent results. Also, one may be much faster than the other depending on the requested number of selected features: if we have 10 features and ask for 7 selected features, forward selection would need to perform ...

WebWhen you implement a non-causal filter, transients get blurred forwards and backwards (e.g. if we want a 2dB ripple, the fact that we're going to be making a forward and backward run using the filter means that we'll want each of these to have 1dB).
