=====What is an artificial neural network?=====
+
The module is composed of multiple panels to perform the different steps of the process: create the groups, pre-visualize the groups and update them if necessary, generate explore and evaluate the generated models.
−
A neural network is a computing system, inspired by our own human brain. It learns from a large dataset (training dataset) containing both the input and the expected output (in our case, the 3D model and its morphology classification). During the training, the network’s settings are adjusted until we achieve automatic classification that matches the expert classification.<br>
+
<br><br>
−
The network can then be tested with any input, preferably not from the training dataset. This allows to evaluate the performance of the network.

The classification can be performed with as many groups as desired. <br>
+
Both the 3D models into the training dataset and those to classify must have the same number of points. The most correspondent the shapes are, the better it is for the computation.
−
Please note that the amount of data is very important. The more data you have, the more accurate the classification will be. Moreover, it is better to have a dataset equally divided into the classes. <br>
+
This can be performed thanks to ShapeAnalysisModule and improved with RigidAlignment/Groups.

To start exploring a PCA space, select the group you want to explore in the group option.<br>
−
'''Preprocessing the data'''
+
Use the sliders to see the shape transform. Each slider represent an eigenvalue of the PCA model, the explained variance value represent how significant this eigenvalue is compared to the other ones.<br>
−
The neural network needs to know from which specific features of the shapes it should learn.
+
<br>
−
Those features are extracted from the shape during that preprocessing phase. <br>
+
 
−
In the ''Advanced parameters'' box, the user can select the features he thinks are the most relevant. Only those selected will be used during the training and in future classification based on this classifier. If the ''Advanced parameters'' tab is closed, by default all the features are used. <br>
+
If you want to play with more sliders, you can use the 'Minimum Explained Variance' and 'Maximum Number of eigenvalues' parameters:
−
The possible features are: Curvedness, Normals, Maximum Curvature, Minimum Curvature, Mean Curvature, Gaussian Curvature, Shape Index, Distances to average shapes.<br><br>
+
*The 'Minimum Explained Variance' parameter will make appear only sliders that have a higher explained variance than the defined value.
 +
*The 'Maximum Number of eigenvalues' parameter is the maximum number of sliders that can be displayed.
 +
<br>
 +
If you want to see (or hide) the mean shape of the group in a superposition of the current shape, you can use the 'toggle mean shape' option.
  
−
The training time of the classifier depends on the number of shapes, their size, the number of groups and the advanced parameters. This can take a while. Be patient! ;)

Prerequisities

Both the 3D models into the training dataset and those to classify must have the same number of points. The most correspondent the shapes are, the better it is for the computation. This can be performed thanks to ShapeAnalysisModule and improved with RigidAlignment/Groups.



Creation of CSV File

CreationofCSV-1.png

This tab allows the user to create a CSV file gathering all the VTK file paths and their corresponding group.
This CSV file lists all the files used in the training dataset. It will be necessary at each step of the process.


The file is automatically loaded into the next steps when it is exported.


CreationofCSV-AddGroup.png
CreationofCSV-ModifyGroup.png
CreationofCSV-ModifyRemove.png

Add Group Add one by one the directories containing the VTK files for each group.
For a new group, the group number is automatically selected.

Modify Group Each group can be edited, with a modification of its corresponding repository.
For this, review the group already added thanks to the spin box.

Remove Group Only the last group added can be removed.
Select the group with the spinbox and remove it.



Preview/Update of the classification groups

PreviewUpdateGroups-1.png

This tab allows the visualization of the 3D models in ShapePopulationViewer, and update the group assigned to the shapes if needed.
If the groups are updated, a new CSV file will be generated.


  • Preview with ShapePopulationViewer
PreviewUpdateGroups-details.png
  1. Select the groups or specific shapes you would like to visualize
  2. Colors that the meshes will have in Shape Population Viewer with the attribute "DisplayClassificationGroup"
  3. Possibility to change the group of a shape thanks to the spinbox in the group row.
  4. Clic on the Preview button, and select all the VTK Files in the pop-up window
  5. If some changes were made on the groups, please export those modifications.



Generating and saving the models

This step will compute the PCA model of each group and will save those models for a future exploration.
You’ll need to provide the CSV file which contains the groups.


  • Perform the computation
  1. Load the CSV file containing the groups if you haven't performed the previous steps
  2. Clic on Process and Export
  3. The exploration interface will appear, it gives you all the tools to explore the generated models.


  • Save the models
  1. Clic on save exploration.
  2. Choose the folder in wich the exploration should be saved and give it a name (ex: 'exploration-name.json').
  3. Saving the exploration will create files as follow:
JSON file : exploration-name.json
Average shapes : exploration-name_[i]_mean.vtk
PYC file : exploration-name.pyc


  • Load an exploration

To load an exploration select a JSON file previously generated ('exploration-name.json') in the JSON File field.

Model Exploration

exploration interface

This section is divided into 3 part:

  1. The PCA exploration
  2. The color modes description and parameterization
  3. The plots visualization and interaction












The PCA exploration

exploration

To start exploring a PCA space, select the group you want to explore in the group option.
Use the sliders to see the shape transform. Each slider represent an eigenvalue of the PCA model, the explained variance value represent how significant this eigenvalue is compared to the other ones.

If you want to play with more sliders, you can use the 'Minimum Explained Variance' and 'Maximum Number of eigenvalues' parameters:

  • The 'Minimum Explained Variance' parameter will make appear only sliders that have a higher explained variance than the defined value.
  • The 'Maximum Number of eigenvalues' parameter is the maximum number of sliders that can be displayed.


If you want to see (or hide) the mean shape of the group in a superposition of the current shape, you can use the 'toggle mean shape' option.


The color modes description and parameterization

group color
unsigned distance
signed distance

There are 3 different color modes to visualize the current shape that can be selected in the Color Mode parameter:

  1. the group color mode
  2. the unsigned distance to mean shape mode
  3. the signed distance to mean shape mode


  • The group color mode:

This mode will display the shape with the color associated with his group.
To change the color of a group, click on the white colored square next to the group selection and select a new color.



  • The unsigned distance to mean shape mode

This mode will display, at each point of the shape, a color representing the unsigned distance between the point and the corresponding point of the group mean shape.
The color scale used is white(0) to red(maximal distance). You can change the color range (ie: the maximal distance) by using the Maximum distance parameter.



  • The signed distance to mean shape mode

This mode will display, at each point of the shape, a color representing the signed distance between the point and the corresponding point of the group mean shape.
The color scale used is blue(minimal distance) to white(0) to red(maximal distance). You can change the color range (ie: the maximal or minimal distance) by using the Maximum distance and Minimal distance parameter. In any case, the white color is fixed to a 0 distance.
A distance will be signed negatively if the associated point is inside the mean shape of the group and positively if the associated point is outside the mean shape of the group.





The plots visualization and interaction

After generation of the models, 2 plots are available:
  • The Variance plot
  • The Projection plot (interactive)

If an evaluation of the models has been processed, 3 other plots are available:
plot area menu
  • The Generalization plot
  • The Specification plot
  • The Compactness plot

We describe them in the Model Evaluation section.

They can be visualized by selecting the corresponding plot chart in the plot area menu (top left button of the plot area).



explqined variance plot
projection plot
  • The Variance plot

This plot shows, for the selected group, the explained variance ratio of each eigenvalue in a bar plot and the cumulated sum of the explained variance ratio in a scatter plot.
The number of components displayed corresponds to the number of sliders available.


  • The Projection plot (interactive)

This plot shows the projection on the 2 first component of the selected group.
You can interact with this plot using a point selection mode ('select points' or 'freehand select points') available in the interaction mode option of the plot area menu.

Selecting one point on this plot will modify the sliders values to show the corresponding shape in the 3D window.
If you select more than 1 point, the mean shape of all the selected points will be displayed.

The point selection modifies ALL the sliders, even those who are not displayed on the interface. if you want to show the shape only using the displayed sliders and not the other ones, you can uncheck the 'Use hidden eigenmodes' option, at the bottom of the sliders.



Model Evaluation

To evaluate the generated models, 3 values can be computed:
  1. The generalization
  2. The specificity
  3. The compactness
launching the evaluation
two parameters are available for the evaluation. one is the number of random shapes that have to be generated to compute the specificity. The other one is defined by the number of sliders currently available if we have 8 sliders, the evaluation is computed on 8 components.
To launch the evaluation, use the Evaluate models option. As the evaluation of the models can take a long time, you have the possibility to abort the evaluation by using the same button.

Visualize the evaluation
When the evaluation is completed, 3 new plots are available in the plot area, one for each value.
You can visualize them by choosing the corresponding plot chart in the plot area menu.

  • Specificity

  • Generalization

  • Compactness
