Data can be readily loaded with the use of the Workspace browser. The browser can be launched by typing '''"browse"''' at the MATLAB command line. If you are using Solo, the browser appears after Solo is launched.
==NEW FEATURES / FIXES==


In this example we'll import an example dataset included with PLS_Toolbox and Solo. The example dataset is in Excel format. Using the '''File''' menu, select '''Import Data...''', and then select '''Excel File (XLS...)'''.
* Add support for non-negative least squares CLS models IF outputting to m-file format (requires function be enabled as sub-functions are added to accomplish the NNLS calculation)
* Add support for approximate nearest neighbor distance via distancemetric option. This is an approximation of the NN distance, but is NOT exact.
* Add support for application of most preprocessing methods to MATRICES
** Allows use of PLS, PCR, PCA, CLS, and PLSDA on x-block of MATRICES (not just vectors) with basically all supported preprocessing methods
* Add basic support for arithmetic on X-block (only - undo on y-block not supported)
* Change "prob" to "probs" in SVMDA so it matches PLSDA outputs
* Fix bug where placeholder variables were not removed from data if SavGol preprocessing was the one and only preprocessing method
* Fix bug which would lead to indexing error in SavGol preprocessing if variables at the END of the spectrum are excluded

==2. Import the Data==
 
Use the resulting dialog boxes to select your file, in this case the example "Redbeerdata.xls". The file is located in the "dems" (demos) folder. Then choose the sheet in the spreadsheet with the data in it, in this case "Sheet 1".

==3. Open Data==
 
The data will be imported into the workspace as a [[DataSet_Object|dataset object]] and appear in the '''Workspace Browser'''. To open the [[DataSet_Editor|DataSet Editor]], you can either right-click on the data and then select '''Edit''' in the context menu, or just double-click the dataset object in the Workspace panel. You can also start an [[Building_Models_Quick_Start|Analysis]]of the data using the Analysis fly-out menu or dragging and dropping the data onto an analysis icon in the Analysis Tools pane (left).

Revision as of 15:49, 15 June 2015

Version 3.2 of Model_Exporter was released in June, 2015. For general product information, see Model_Exporter_User_Guide.

NEW FEATURES / FIXES

  • Add support for non-negative least squares CLS models IF outputting to m-file format (requires function be enabled as sub-functions are added to accomplish the NNLS calculation)
  • Add support for approximate nearest neighbor distance via distancemetric option. This is an approximation of the NN distance, but is NOT exact.
  • Add support for application of most preprocessing methods to MATRICES
    • Allows use of PLS, PCR, PCA, CLS, and PLSDA on x-block of MATRICES (not just vectors) with basically all supported preprocessing methods
  • Add basic support for arithmetic on X-block (only - undo on y-block not supported)
  • Change "prob" to "probs" in SVMDA so it matches PLSDA outputs
  • Fix bug where placeholder variables were not removed from data if SavGol preprocessing was the one and only preprocessing method
  • Fix bug which would lead to indexing error in SavGol preprocessing if variables at the END of the spectrum are excluded


Model Interpreter

  • Allow input of matrix instead of just vectors (some methods support applying to matrix)
  • Force numeric conversion to be done expecting period as decimal separator (resolves problems interpreting models on systems set to other numeric formats like in France)
  • Move math steps into new MEMath object (simplifies code - exposes mathematical operations to caller)
