I understand you're seeking an updated solution given advancements in machine learning features and Mathematica capabilities. Is there a straightforward method available for visualizing a decision tree classifier? Python's libraries like graphViz have been helpful in visualizing trees, simplifying data interpretation. Despite searching various forums, I haven't found a simple tool for mapping tree branches and nodes ..read more

I have the new user of Wolfram, now I am trying to type the code by using NeuralNetwork, the coding to be like this. index = {103.244, 145.125, 156.575, 179.2, 225.758, 315.217, 235.025, 248.392, 272.283, 265.067, 259.2, 265.517, 259.2, 254.6, 303.833, 353.425, 366.775, 339.092}; time = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18}; trainData = Thread[time→index] ; p=Predict[trainData, Method→"NeuralNetwork"] p[{19 , 20, 21}] However, the system error of "Predict: The data being evaluated is not formatted correctly" May I ask why the format is not correct? And how can I solve ..read more

By deleting some layers in a Net, like Abrita showed recently in a webinar, I get lots of errors, as the Array sizes of the output of a layer to the new next input of a layer do not mach up any more. How can I adapt mismatches in Array sizes from Output of Layer n to Input layer n+1. Thanks, Bert ..read more

A Wolfram U Daily Study Group focusing on **LLMs and Wolfram Tech** will be starting soon! Join Wolfram Experts [@Alan Joyce][at0] , [Rick Hennigan][1], [Timothee Verdier][2] and [@Jon McLoone][at1] and a group of fellow enthusiasts to learn about all the different ways you can use Wolfram tech along with Large Language Models (LLMs). Our topics for the study group include the Wolfram GPT, Chat Notebooks and LLM Functionality in Wolfram Language. The sessions will feature a number of fun examples that will show you how you can combine the computational powers and curated knowledge of Wolfram L ..read more

I recently upgraded Mathematica from version 13.2 to 14.0 on my workstation, and when attempting to execute a script, I obtained the following error associated with the Classify function: Classify: TargetDevice -> GPU requires a restart of your Wolfram Language session On the Mathematica Stackexchange forum, I was directed to a thread discussing a similar error that was due to an incompatibility with the MXNResources paclet in version 12 vs. version 13. In that instance, uninstalling the Paclet resolved the issue. However, not being familiar with its functionality, I am hesitant to do so be ..read more

Hi everyone I have problem and I would appreciate it if someone could guide me. I'm Master student and I working on my thesis. I work on material science and I use deep learning for my studies. The method I use is CNN here. for this problem I must generate Images. I'm using a paper for this work and it's my reference for my job. Autor use Mathematica for project and he generate image with Mathematica. He did not clearly mention what he did. in part of paper he say : (Mathematica is used to generate pseudorandom images using several image processing functions that create asymmetrical Rorschach ..read more

Hello fellow Mathematica users, I trust a lot Mathematica's machine learning framework, which automatizes many aspects of ML by default and let user enjoy an easy to use tool. Lately, I realized that merely changing the order of features during training can significantly affect the predictive function, as shown in my example. **Importantly, this change occurs without altering the names, types, values or values sequence of the features, only their order as a column**. I even used "DirectTraining" in PerformanceGoal to prevent search of a model. Why does the order of feature columns impact the c ..read more
