Latest Patents
One of Marcelo's latest patents is focused on shopping search engines. This innovative web search system utilizes human input to rank the relevance of results returned for various sample search queries. The search results are organized into groups, allowing for effective training and validation with the ranked results. By implementing consistent guidelines for human evaluation, the system ensures reliable results across multiple evaluators. Additionally, after programming and validating a machine learning categorization tool, such as MART, it can provide an absolute rank of relevance for documents returned, rather than relying solely on keyword matches and click counts. This approach allows for the exclusion of documents with lower relevance rankings when developing related refinements, such as category and price sorting.
Another significant patent by Marcelo involves the automated identification of image outliers. This technology enables the automatic detection of outlier images—those that differ substantially from other images in a set. Each image can be assigned one or more penalty values that quantify its difference from others in the set. A threshold is established based on these penalty values, allowing for the identification of outlier images. The penalty values are calculated based on the differences in color values for each pixel compared to a predetermined range, providing a robust method for image analysis.
