By introducing increased geographic and data set precision into the ad targeting process, we can deliver neighborhood-level targeting on a national scale, empowering brand marketers to focus their ad spend on their prime target consumers living within the radius of the store".
From Table 7 it can be seen that, out of 254 potential publications in the test set for this topic and a test set precision of 0.457, 46 alerts would be initiated over the 31 month time period.
These are generally based on two underlying characteristics of a search result set: precision, defined as the number of relevant documents that the search system has retrieved, divided by the total number of documents that were retrieved; and recall, the number of relevant documents that were retrieved, divided by the total number of relevant documents that are available in the collection.
Pooled CSF and plasma quality control (QC) samples were both assayed in duplicate on each mitrotitre plate, setting the precision of the assay across all microtitre plates.
Percentage of actives recalled in the top 1% and top 5% of the ranked validation sets, precision of predicted positives, area under the Receiver Operating Characteristic curve, F-measure and the Matthews Correlation Coefficient.
These figures of merit include recall in the top 1% and top 5% of the ranked validation sets, precision, F-measure, area under the Receiver Operating Characteristic curve and Matthews Correlation Coefficient.
For each AGRIS record in the test set, precision ranged from 0.2 to 0.8.
The average precisions, recall and their SDs are very similar to those of sets 1 and 2 [voxel-based GHMRF classification, averaged over all sets: precision 0.45 (0.12), recall 0.51 (0.12); object-based GHMRF classification: precision 0.62 (0.14), recall 0.62 (0.14)] (Supplementary Table S1).
Optimized strategies, sensitivity-maximizing version and sensitivity- and precision-maximizing version, in EMBASE had greater overall sensitivity (sensitivity in the full gold standard set) and precision than the comparable MEDLINE strategy.
In fact the observed performance is very close to this limit, so that even four layers of neurons away from the receptors it is still the physics of the inputs that sets the precision of computation.
