Title: Lisa Purvis: Innovator in Software Voting Systems
Introduction
Lisa Purvis is a notable inventor based in Pleasanton, CA (US). She has made significant contributions to the field of software voting and prediction systems. With a total of 3 patents, her work focuses on enhancing the efficiency of preference elicitation among participants.
Latest Patents
One of her latest patents is titled "Scoring members of a set dependent on eliciting preference data amongst subsets selected according to a height-balanced tree." This innovative system iteratively solicits participant preferences between members of a set, utilizing a binary tree to minimize the number of iterations required. As each member is considered, it is pairwise compared with select members represented by nodes already in the binary tree. The process begins at the root node and continues to a leaf node. The newly considered member is placed as a new leaf node, and the tree is height-rebalanced as necessary. Red-black tree coloring and tree rotation rules can be applied for this purpose. Throughout the tree-building process, yes/no preference tallies are maintained for each member, which are ultimately used for scoring. The height-rebalancing of the tree is crucial in minimizing the iterations needed to accurately score each member relative to its alternatives.
Career Highlights
