Notebook Assistant : a review

I've been testing the usefulness of the new Notebook Assistant with Mathematica 14.2, and I have some thoughts. I've been a user of Mathematica since version 1.1, and have witnessed personally some of the boom and bust cycles of artificial intelligence. In the 1990s, I developed and implemented a highly successful expert system, which, although is primitive compared to current AI efforts, was state-of-the-art at the time. All of the demos of the notebook assistant are impressive, and it is remarkable that it works as well as it does. Once I got to the hands-on stage, I realized that this is re ..read more

A = {{1, 1, 1}, {0, 2, 3}, {5, 5, 1}}; Inverse[A] = {{13/8, -(1/2), -(1/8)}, {-(15/8), 1/2, 3/8}, {5/4, 0, -(1/4)}} svdInverse[a_?MatrixQ] := Module[{u, s, v}, {u, s, v} = SingularValueDecomposition[a]; Return[v . Inverse[s] . ConjugateTranspose[u]]]; svdInverse[A] = Over 100 lines of indecipherable garbage. svdInverse[a_?MatrixQ] := Module[{u, s, v}, {u, s, v} = SingularValueDecomposition[a]; Return[v .

Creating a Machine-Learning Model for Kidney Stone Identification using Urine Samples
Wolfram Community » Machine Learning
by Saloni Roy
1w ago
**Purpose** My purpose is to take urine sample data from the James Elliot Urology laboratory and build a machine learning model that can take these samples and with reasonable accuracy give us a probability that the patient has a Kidney Stone. This will act as an efficient and accurate initial level “screening” that can improve medical procedures around the world. **Introduction and Background Information:** Kidney Stones are hard deposits made of minerals and salts that form inside the kidney. They can affect any part of the urinary tract, from your kidneys to your bladder. The stone forms wh ..read more

Generalizing the MSE loss function to weighted least squares for neural networks
Wolfram Community » Machine Learning
by Ruth Lazkoz
3M ago
Hello Wolfram Community! I’m working on implementing a custom loss function in Mathematica to apply a weighted least squares approach to neural networks. Specifically, I’d like to modify the standard mean squared error (MSE) loss function to incorporate weights, so it can account for the varying importance of different data points in training. **Objective** The standard MSE loss function simply calculates the average squared difference between the actual values and the predicted values. I’d like to generalize this to a weighted mean squared error, or weighted least squares (WLS), by including ..read more
