Synopsis of the SEQENS components. (a) The dataset is comprised of observations \({O_i}\) (rows) and variables or features \({F_j}\) (columns). (b) Observations are divided into a train set and a test set. (c) Each partition is sent to multiple sequential feature selectors. Each selector outputs a scored subset of selected variables. (d) Low-scored subsets are discarded. (e) The result is aggregated from the selected subsets. (f) The output is a list of features ranked by relevance
