On the dataset management window, you can create or add datasets and preview datasets you used in the past.

 

Using the dataset management window

 

1 Creating an image classification dataset based on images grouped in different folders for each image category

  1. Have the image files grouped in folders ready.

  2. In the window that appears after the application starts, select DATASET to open the dataset management window.

  3. Click Create Dataset.
    Or, press Ctrl+N on the keyboard.
    An image classification dataset creation dialog box appears.

  4. Specify the settings for creating the dataset.
    5. Source Dir Specify the folder containing the folders with grouped images.
    Output Dir Specify the folder to output the created dataset to.
    Shaping Mode If the aspect ratio of the images in each folder is different from the aspect ratio indicated by the specified size, specify the method for aligning the aspect ratio.

    Trimming: The edges are trimmed to align the aspect ratio.
    Padding: The edges are padded with zeros to align the aspect ratio.

    Output Color Ch Set the number of color channels in the output images to 1 (monochrome) or 3 (RGB color).
    Output Width Specify the output image width.
    Output Height Specify the output image height.
    Shuffle the order of the data Sets the data order to shuffle (ON by default).
    FileName Specify the name of the dataset CSV file to be created.
    Ratio (%) Set the ratio of the data used in the dataset CSV file to be created.
    The total of the ratios of File 1 and File 2 must be 100 (%).
  5. Click Apply to start creating the dataset.

 

2 Opening a dataset stored on the disk

  1. Open Dataset.
    Or, press Ctrl+O on the keyboard.
  2. Select the dataset file (.csv file) you want to open.

 

3 Previewing the datasets you used in the past

Click a dataset you used in the past shown in the dataset management window.
Or, use the up and down arrow keys to select the dataset.

A preview of the selected dataset appears on the right side of the window.

 

4 Filtering the dataset you used in the past

Enter a search string in the text box to the right of the magnifying glass icon at the top right of the dataset management window.

 

Only the datasets that contain the specified string in the file name or description are shown.

 

Reference

You can specify multiple search strings by separating them with a space. Enclose search strings that include spaces with double quotations.

 

5 Opening a folder containing datasets you used in the past

Right-click a dataset you used in the past to open a shortcut menu, and click Open File Location.

 

6 Removing datasets you used in the past from the dataset management window

Right-click a dataset you used in the past to open a shortcut menu, and click Remove.

 

Reference

The dataset you remove is only removed from the dataset management window, not from the disk.

 

Reference

A dataset you removed will reappear in the dataset management window if you open it again from Open Dataset.

 

7 Uploading a dataset to the Neural Network Console Cloud

  1. From the datasets shown in the dataset management window, click the dataset you want to upload.
    Or, use the up and down arrow keys to select the dataset.
  2. In the dataset preview at the right side of the window, click Upload Dataset. A Upload Dataset dialog box appears.

  3. Copy the token displayed in the upload window of the Neural Network Console Cloud, and click Paste to paste it in the Token box.
  4. Click Upload.
