In this article we got to know a few methods of generating synthetic datasets for various problems. Synthetic datasets help us evaluate our algorithms under controlled conditions and set a baseline for performance measures. Python has a wide range of functions that can be used for artificial data...
In the previous two examples, we usedlinalg.inv()andlinalg.dot()methods to find the solution of system of equations. However, the Numpy library contains thelinalg.solve()method, which can be used to directly find the solution of a system of linear equations: ...
