Spam Filtering using Naïve Bayesian classifier In Spam filtering problem the examples or observations are the emails, and the features are the words in the email. When using words as features we suppose that some words are more likely to appear in spam than in non-spam, which is the basic premise underlying most spam filters. The attached folder contains three files: Spmabase.Documentation: has all the information about the dataset Source Number of examples (instances or observations) Number of attributes Attributes...

Using the below information - Discuss the difference between Developmental and Administrative uses of performance appraisals. Developmental versus Administrative Uses of Performance Appraisal Another key debate in performance appraisal is how to balance the foundational performance appraisal purposes of employee development and administrative decision-making (Bernardin & Beatty, 1984). Some researchers argue that appraisals are more accurate and useful for improving performance if they are diagnostic and not linked to pay or other administrative outcomes. Opponents argue that employees will not...
