Webinterface for computing various linear algebra operations such as matrix-vector products, trace, frobenius norm, and so on, where the matrix is either the FIM or the NTK, leveraging recent advances in approximating these matrices. We hereby introduce the library and motivate our design choices, then we demonstrate it on modern deep neural networks. WebFisher information is a statistical technique that encapsulates how close or far some random instance of a variable is from its true parameter value. It may occur so that there …
