Deep learning is a type of supervised machine learning in which a model learns to perform classification tasks directly from images, text, or sound.
Deep learning is usually implemented using a neural network.
The term “deep” refers to the number of layers in the network—the more layers, the deeper the network.
A convolutional neural network can have hundreds of layers and each layer learn to detect different features of an image.
Filters are applied to each training image at different resolutions and size, and the output of each convolved image is used as the input to the next layer.
The filters can start as very simple features, such as brightness and edges, and later on it goes deep to extract complex features.
Like other neural networks, a CNN is composed of an input layer, an output layer, and many hidden layers in between.

If you get cuda error , it means there is issue with your GPU, try to run model again after restarting MATLAB, or during training use cpu.
In a trainingoptions provide this property and value 'ExecutionEnvironment','cpu'
Getting the following error
Error using trainNetwork (line 150)
An unexpected error occurred trying to retrieve CUDA device properties. The CUDA error was:
How do I fix this!
good example to learn deep learning! thanks
