Unlike other texts, the treatment allows the use of the "modified Moore method" approach by working examples and proof opportunities into the text in order to encourage students to develop some of the content through their own experiments and arguments while reading the text. guides and leads the reader through the learning path . Since each talk can either be selected or not selected as part of the final watch list, the decision variable is binary in nature (1=Selected, 0=Not Selected), The objective function is the sum over all rows of the views for each talk. The outcome of data science pipeline is uaully predictions, patterns and insights from data (typically without any notion of constraints) but that alone is insufficient for business stakeholders to take decisions. .
