Modulation

/ˌmɒd.jʊˈleɪ.ʃən/

“Turning signals into messages, one wave at a time.”

Modulation is the process of embedding information onto a carrier wave by varying one or more of its fundamental properties: amplitude, frequency, or phase. It is the bridge between raw data and physical transmission, allowing digital or analog signals to traverse mediums like radio waves, optical fibers, or electrical circuits.

Information Gain

/ˌɪn.fərˈmeɪ.ʃən ɡeɪn/

noun … “measuring how much a split enlightens.”

Information Gain is a metric used in decision tree learning and other machine learning algorithms to quantify the reduction in uncertainty (entropy) about a target variable after observing a feature. It measures how much knowing the value of a specific predictor improves the prediction of the outcome, guiding the selection of the most informative features when constructing decision trees, such as Decision Trees.

INT32

/ˌɪnt ˈθɜːrtiːˌtuː/

noun … “a signed 32-bit integer with a wide numeric range.”

INT32 is a fixed-width numeric data type that occupies exactly 32 bits of memory and can represent both negative and positive whole numbers. Using Two's Complement encoding, it provides a range from -2147483648 to 2147483647. The most significant bit is reserved for the sign, while the remaining 31 bits represent magnitude, enabling predictable arithmetic across the entire range.
