Splet13. jul. 2008 · A trace ratio (TR) criterion is derived which selects features using a subset- level score rather than a feature-level score to perform feature selection and is applied to the challenging problem of gender determination using features delivered by principal geodesic analysis. 4 PDF View 2 excerpts, cites methods Splet08. dec. 2016 · First we need to introduce yes another vector operation called the Outer product. (As opposed to the Inner product (dot product)). Let u be an m by 1 column vector and v be an n by 1 column vector. Then Outer (u, v) := u * Transpose (v), yielding an m by n matrix where the (i, j) element equals u_i * v_j. michael burns solicitor malahide
