示例1: computeSimilarityMemory
protected function computeSimilarityMemory()
{
// data is already loaded by $this->loadDirectMatrix()
watchdog('recommender', "Computing similarity scores in memory. Could be CPU resource intensive. Please be patient");
$this->similarityMatrix = Matrix::correlation($this->directMatrix);
// cleanaup
$this->saveSimilarityMatrix($this->lowerbound);
