However, in order to improve the performance of reverse engineering and statistical inference procedures aimed to estimate gene\u2013gene connectivity links, some kind of regularization is usually needed to reduce the overall data complexities, together with ad hoc feature selection to uncover biologically relevant gene associations. The paper deals with feature selection by projective methods; in particular, it addresses some issues: Can the impact of noise on the data be limited by shrinkage or de-noising? How can complexity from convoluted dynamics associated with microarray measurements be discounted? In modeling such data, how to deal with over-parametrization, and control it? The problem of aliasing is then discussed and classified into two categories according to the trade-off between biological relevance and noise, and finally reported in analytical form via subspace analysis. <\/jats:p>","DOI":"10.1142\/s0219720009004254","type":"journal-article","created":{"date-parts":[[2009,7,23]],"date-time":"2009-07-23T11:31:54Z","timestamp":1248348714000},"page":"685-700","source":"Crossref","is-referenced-by-count":2,"title":["ALIASING IN GENE FEATURE DETECTION BY PROJECTIVE METHODS"],"prefix":"10.1142","volume":"07","author":[{"given":"ENRICO","family":"CAPOBIANCO","sequence":"first","affiliation":[{"name":"CRS4 Bioinformatics Laboratory, Technology Park of Sardinia, Localita' Piscinamanna Bldg. 3, 09010 Pula (Cagliari), Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","volume-title":"Encyclopedia of Measurement and Statistics","author":"Abdi H.","year":"2007"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.97.18.10101"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0406767101"},{"key":"rf4","volume-title":"Introduction to Linear Algebra","author":"Strang G.","year":"2003"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.98.4.1693"},{"key":"rf6","unstructured":"I.
