Hidden false positives in the visual field

Visual Semantics for Reducing False Positives in Video Search

This research explores the interaction of textual and visual information in video indexing and searching. Much of the recent work has focused on machine learning techniques that learn from both text and image/video features, e.g. the text surrounding a photograph on a web page. This is useful in similarity search (i.e. searching by example), but has drawbacks when more semantic search is desire...

False positives in cancer epidemiology.

BACKGROUND A recent attempt to estimate the false-positive rate for cancer epidemiology studies is based on agents in International Agency for Research on Cancer (IARC) category 3 (agent not classifiable as to its carcinogenicity to humans) in the IARC Monographs Program. METHODS The estimation method is critiqued regarding biases caused by its reliance on the IARC classification criteria for...

Handling false positives in the genomic era.

Both procedures used iodinated contrast media, iohexol (Omnipaque 350; GE Healthcare) in this case. The cause of the “floating gel” was an increase in serum density from residual contrast dye still present in the catheter used for the procedures (1 ). Laboratory tests should not be performed, even if the serum is extracted from beneath the gel barrier. The effect of residual dye is unknown, but...

CORP: Minimizing the chances of false positives and false negatives.

Statistics is essential to the process of scientific discovery. An inescapable tenet of statistics, however, is the notion of uncertainty which has reared its head within the arena of reproducibility of research. The Journal of Applied Physiology's recent initiative, "Cores of Reproducibility in Physiology," is designed to improve the reproducibility of research: each article is designed to elu...
