What is CNN?
A convolutional neural network (CNN or ConvNet) is a network architecture for deep learning that learns directly from data.
CNNs are particularly useful for finding patterns in images to recognize objects, classes, and categories. They can also be quite effective for classifying audio, time series, and signal data.

How CNNs Work
A convolutional neural network can have tens or hundreds of layers that each learns to detect different features of an image.
Filters are applied to each training image at different resolutions, 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 increase in complexity to features that uniquely define the object.
Who is the South African CNN correspondent?
Before joining CNN, Curnow was a reporter for the BBC and for the South African Broadcasting Corporation in the Mandela era.
Curnow started reporting for CNN in 2001 in London, covering the UK and Europe. She is currently based in Atlanta, at CNN’s World headquarters.
