Definition of Entropy Entropy: Entropy is a measure of the unpredictability of a system. In information theory, entropy ( ) is a measure of the uncertainty associated with a random variable. Entropy is defined as the average amount of information that is not known about the value of a random variable. When is Entropy used?…
Definition of Time Series Data A time series is a sequential set of data points, typically measured at successive points in time. Time series analysis is the process of analyzing time series data in order to identify patterns and forecast future values. Time series data can be used to measure and predict changes in everything…
Definition of Upstream Upstream: Upstream and Downstream are terms used in data science to describe the flow of data or what order events occur. Data is processed and becomes more refined as it moves through the various processes. Upstream is closer to the source. When discussing a specific process step, Downstream is a term that…
Definition of Operational Definition Operational Definition: An operational definition is a specific, quantitative definition of a term, which can be used to measure or calculate it. This definition is typically found in a laboratory setting, where a scientist can observe and measure the term’s properties. For example, the operational definition of the speed of light…
