open deep network roller coaster in matlab

To open and run Deep Network Roller Coaster in MATLAB, you need to follow these steps:

1. Open MATLAB and go to the Deep Network Designer App.

2. Load the pretrained network by clicking on the "Import" button and selecting the network file.

3. Once the network is imported, you can visualize it by clicking on the "Visualize" button.

4. Load the input data by clicking on the "Import" button and selecting the test image(s).

5. Evaluate the performance of the network by clicking on the "Evaluate" button.

Here's an example code snippet to load a pretrained network and test an image:

main.m
% Load the pretrained network
net = alexnet;

% Load the input image
img = imread('test_image.jpg');

% Preprocess the image
img = imresize(img, [227, 227]);
img = im2single(img);

% Classify the image
pred = classify(net, img);
