!!! Overview [{$pagename}], Well there is almost no common [Taxonomy] as the field covers several different disciplines. Recommendations: * __[lowercase]__, bold-face letters to refer to [vectors] * __[UPPERCASE]__, bold-face letters to refer to [matrices|Matrix] * ''italics'' to refer to single elements in a [vector] or [matrix] * transpose - "superscript T" an operation that transforms a column [vector] into a row [vector] and vice versa: ** transpose applied to a [Matrix] to reflect the [Linear transformation] a [Matrix] without changing the [Basis vector] Generally some poorly used terms are: * [features] * labels which we will call [Classification] * [hyperparameters] !!
