In predictive analytics, a table of confusion (sometimes also called a confusion matrix) is a table with two rows and two columns that reports the number of true positives, false negatives, false positives, and true negatives. This allows more detailed analysis than simply observing the proportion of correct classifications (accuracy).
A Gamo Big Cat 1200 in loading configuration. Gamo Outdoor S.L.U, or simply Gamo, is a Spanish airgun manufacturer based in Barcelona, Spain, and is the largest producer of airguns in Europe and the largest producer of airgun pellets in the world. The company was founded in 1959, as El Gamo, and airgun production first started in 1961.
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens. It is widely used in optical engineering laboratory work to analyze and ...
A receiver operating characteristic curve, or ROC curve, is a graphical plot that illustrates the performance of a binary classifier model (can be used for multi class classification as well) at varying threshold values. The ROC curve is the plot of the true positive rate (TPR) against the false positive rate (FPR) at each threshold setting.
Lawson criterion. The Lawson criterion is a figure of merit used in nuclear fusion research. It compares the rate of energy being generated by fusion reactions within the fusion fuel to the rate of energy losses to the environment. When the rate of production is higher than the rate of loss, the system will produce net energy.
Single-cell DNA genome sequencing involves isolating a single cell, amplifying the whole genome or region of interest, constructing sequencing libraries, and then applying next-generation DNA sequencing (for example Illumina, Ion Torrent ). Single-cell DNA sequencing has been widely applied in mammalian systems to study normal physiology and ...
July 10, 2024 at 4:10 PM. Today, July 10, is National Piña Colada Day, which means it's time to honor the drink made by blending coconut cream, pineapple juice, white rum and ice, which was ...
Inertial confinement fusion ( ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with fuel. The targets are small pellets, typically containing deuterium ( 2 H) and tritium ( 3 H). Energy is deposited in the target's outer layer, which explodes outward.
