55. Least Squares Approximation for Underdetermined Systems

This video explores how to find the best possible solution to systems of equations with fewer equations than unknowns using the least squares approximation method. You will learn how underdetermined systems arise, why they often have infinite solutions, and how the least squares approach identifies the most stable and meaningful answer. The lesson includes a clear explanation, a practical Python implementation, and a real-world interpretation of what the minimum-norm solution means in applications like data fitting, control systems, and optimization. #EJDansu #Mathematics #Maths #MathswithEJD #Goodbye2024 #Welcome2025 #ViralVideos #LeastSquares #LinearAlgebra #UnderdeterminedSystem #Pseudoinverse #MatrixAlgebra #Optimization #NumericalMethods #MathConcepts #PythonMath #EngineeringMath #AppliedMathematics #DataFitting #ComputationalMath #MoorePenrose #MatrixDecomposition #LinearSystems #VectorSpaces #MathTutorial #MathLearning #EJDansu -Feel very free to follow me on all channels: https://linktr.ee/ejdansu -Tech-relevant playlists: Basic Calculus https://youtube.com/playlist?list=PLMxwp487ysbOsfExwUvVqs2XGT40iXLJe&si=r7kJX8adApJMdTVq Data Analysis with Python https://youtube.com/playlist?list=PLMxwp487ysbMDy5ZTlLqdnO8Nic2K5Qis&si=dGP-Urww7JEVfwVX Game Theory https://www.youtube.com/playlist?list=PLMxwp487ysbM5fWlnUQFcRCLmBwbTawVY Graph & Network Theory https://youtube.com/playlist?list=PLMxwp487ysbMM_j0w8m7TSGccZEujOE8K&si=AHmJjv-VdoudCSDw Linear Programming https://youtube.com/playlist?list=PLMxwp487ysbONM_hRJVUrgAPtjYns48y-&si=xwlBoYkTFRJawb15 Matrices https://youtube.com/playlist?list=PLMxwp487ysbNU60Ea9Bv4d-ySAALm-kLF&si=ajCo2gRsCShPaumG Numerical Analysis https://youtube.com/playlist?list=PLMxwp487ysbPjm1qNDwdIjWIMsMjSEZCT&si=pNhOY_fh-ntlGszn Numerical Optimisation Techniques https://youtube.com/playlist?list=PLMxwp487ysbNcc7hUtpBCqh6d547Qacs1&si=FRvsdLXSMDtHuCu2 Probability https://youtube.com/playlist?list=PLMxwp487ysbM3JIQO0B3sfgbsJxLvWES1&si=kgN2832KDwiBISAc Scientific Computing with Python https://youtube.com/playlist?list=PLMxwp487ysbMLck645K4WYMsOkJjDNxeW&si=Idw5xUzRVs2eVrd1 Set Theory https://youtube.com/playlist?list=PLMxwp487ysbM7HDyJd4QUOQSNYDGW46fB&si=C53NJMtSPJUAsn2F SQL with Python https://youtube.com/playlist?list=PLMxwp487ysbMZdveFzwMUHNGPJjjsdBew&si=hjIAYShUtfG8DDds Statistics https://youtube.com/playlist?list=PLMxwp487ysbNMbvA4nkXvFG4wDo8WCce1&si=DCIeS7ktGwQga3zy Vectors https://youtube.com/playlist?list=PLMxwp487ysbM5FH1lqr_WJiNQFBpsopJw&si=l4uXaOEDXb_k8YYM
