Industrial Machinery Anomaly Detection, Part02_Modeling.mlx: extractLabeledData

hi all,

within "Industrial Machinery Anomaly Detection", livescript 'Part02_Modeling.mlx"

line8 is : X = extractLabeledData(featureTrain, "Label", "After");

when i try to run this line, matlab returns 'unrecognized function or variable extractLabeledData'

=> extractLabeledData seems not to be known by matlab help and is neither a variable.

am I missing something, how to overcome this issue ?

best regards

Juliette

Hi Juliette,

Referring to this GitHub example https://github.com/matlab-deep-learning/Industrial-Machinery-Anomaly-Detection

You'll need to open the MATLAB project first and it will setup the path for the example.

To Run:

1. Open the MATLAB Project AnomalyDetection.prj
2. Run Part 1 - Data Preparation & Feature Extraction
3. Run Part 2 - Modeling

Hi David,

thanks for the reply, I've followed your indications (excepted running Part1 because it's not possible to buy this toolbox while being a student), but I still got a error flag when I run the Part 2 (see below)

I guess " X=extractLabeledData(featureTrain,"Label","After")" put in X the recording tagged with "after". So I'm looking for another to perform this operation.

I guess the red warning triggered by the absence of the function => how this function is defined and why is it in the mlx file

best regards

Hi Juliette, the file extractLabeledData is in the HelperFunctions subfolder. If you're receiving the error, it means the path wasn't setup correctly.

After opening the AnomalyDetection.prj, what is the output of:

>> which -all extractLabeledData

[juliette soula]

Hi David,here is the result:

>>which -all extractLabeledData

'extractLabeledData' not found.

You're right "extractLabeledData.m" is "hidden" in the HelperFunctions subfolder.

I've copied the file to the level of Part02_Modeling.mlx file to have it work
