비전공자의 인공지능 고군분투기

안녕하세요 오늘은 7강 Solving Ax = 0: Pivot Variables, Special Solutions Space and Nullspace에 대해 배우겠습니다.  Solving Ax = 0: pivot variables, special solutions* Number of piviots = Rank of AThe nullspace of a matrix A is made up of the vectors x for which Ax = 0.행렬 A의 nullspace는 Ax = 0인 벡터 x로 구성된다. (중요한 점은 A행렬은 독립적이지 않다.) our algorithm for computing the nullspace of this matrix uses the method of eliminatio..

안녕하세요,오늘은 MIT Gilbert Strang교수님의 Linear algebra 6강 Column Space and Nullspace에 대해 리뷰해보도록 하겠습니다.   Vector SpaceA vector space is a collection of vectors which is closed under linear combinations. In other words, for any two vectors v and w in the space and any two real numbers c and d, the vector cv + dw is also in the vector space. A subspace is a vector space contained inside a vector space. Ve..

안녕하세요, 오늘은 MIT Gilbert Strang교수님의 선형대수 강의 Lecture#2 Elimination with Matrices로 공부해보도록 하겠습니다.  Method of EliminationElimination is the technique most commonly used by computer software to solve systems of linear equations. It finds a solution x to Ax = b whenever the matrix A is invertible. In the example used in class,The number 1 in the upper left corner of A is called the first pivot.The first..
