Sparse identification of nonlinear dynamics (SINDy) is a powerful tool used to learn the true dynamics of a system from observational data. This technique is applicable to a wide range of systems, including plasma, fluid flow, and economic models. The cindy algorithm augments the right-hand side of possible model terms to include nonlinear terms, in order to find the fewest terms in a library of candidate dynamics that describe the x dot, y dot, and z dot equations. This allows for models that are more like the Lorentz 1963 model, which is able to describe the rich dynamics of the atmosphere.

**00:00:00**SINDy is a sparse identification algorithm for learning dynamical systems models from time series data.
