diffusion model

A diffusion model describes how ideas, information, or products spread over time among people or through networks. Imagine a drop of ink in water; initially, it stays concentrated, but gradually, it spreads out until the color is distributed evenly. Similarly, in a diffusion model, certain factors—like social influence, communication, and time—affect how quickly and widely something spreads through a population. This concept is applied in various fields, from marketing to science, to understand behaviors and trends in society.
