Signal-To-Noise Ratio

Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise. While SNR is commonly quoted for electrical signals, it can be applied to any form of signal (such as isotope levels in an ice core or biochemical signaling between cells).The signal-to-noise ratio, the bandwidth, and the channel capacity of a communication channel are connected by the Shannon–Hartley theorem.

    … Google figures out what ad to show in search. The quality of the decisions these systems make is reliant on: 1) more static data sets with higher signal-to-noise ratio to help train the models and 2) the ability to learn based on outcomes. That means the most intelligent systems must use first-party data and backend data that will be looped back…
