this step converts the detected face data into vector values in a high-dimensional space, known as facial feature values. Due to the nature of vectors, the similarity between two facial feature values can be assessed by calculating the distance between the two vectors. The task of the AI mo...
Visual acuity tests how sharp your vision is at a given distance and is different from contrast sensitivity. Visual acuity is tested by reading black letters against a white background (Snellen chart) in indoor conditions with bright lights. It is a high-contrast procedure designed to test the ...

both labeled and unlabeled. The closer two nodes are based on some chosen measure of distance, likeEuclidian distance(link resides outside ibm.com), the more heavily the edge between them is weighted in the algorithm. Starting from the labeled data points, labels then iterativelypropagatethrough ...
Formulating and implementing a strategic plan is core to the modern university leader’s job description. But amid complaints that such documents are vacuous, generic and irrelevant to the wider community, John Ross asks how the process can be impr
