Linear discriminant analysis (LDA) faces challenges in practical applications due to the small sample size (SSS) problem and high computational costs. Various solutions have been proposed address SSS both ratio trace LDA (TRLDA). However, iterative processing of large matrices often makes computation process cumbersome. To this issue, for TRLDA, we propose a novel random method that extracts orthogonal bases from matrices, allowing computations with small-sized matrices. This significantly...

Teacher talk is the major resources of comprehensible target language input learners are likely to receive in foreign classroom teaching. The current study, based on class videotapes four college English teachers and questionnaires, attempted investigate analyze phenomenon teacher time, questioning pattern, feedback pattern. findings showed that although communicative approach interaction highly advocated adopted, one-way communication still dominants teaching learning University Jinan,...
