<electronics> A technique for reducing the amount of {Radio Frequency Interference} spread via power supply connections. VCC is a common name for the non-ground power supply line in circuits based on bipolar transistors. When part of a circuit generates lots of radio-frequency noise, that portion of the power plane can be isolated from the rest of the circuit and power delivered to it via a {low pass filter}, usually a PI filter, as shown in the diagram below. source ________inductor_________ load | | capacitor capacitor | | ground ground This helps to shield the rest of the circuit from the noise generated by the load.

Naive Bayes classifiers are a popular statistical technique of e-mail filtering. They typically use bag-of-words features to identify email spam, an approach commonly used in text classification.
