WebSep 26, 2024 · If A has a right inverse A − 1, we can set X = A − 1 b and we easily verify that, with an X chosen like this, we get A X = A A − 1 b = I b = b. Hoewever, we do not know if this is the only way of obtaining an X that satisfies A X = b. Therefore, we say that A X = b has at least one solution. WebAug 31, 2024 · I am trying to solve a linear inverse problem Ax=b using Deep Neural Network. But I am totally new to machine learning and all tutorials are about classification.

WebWe can solve this system of equations using the matrix identity AX = B; if the matrix A has an inverse. Namely, we can use matrix algebra to multiply both sides of the equation by A 1, thus getting A 1AX = A B: Since A 1A = I 2 2, we get I 2 2X = A 1B; or X = A 1B: Lets see how this method works in our example.
