You would start by showing the child a picture of a circle and telling them that it is a circle. Then, you would show them a picture of a square and tell them that it is a square. The child would start to learn that circles and squares are different shapes.<\/span><\/p>\n<p><span style=\"color: #000000;\">\n\n<\/span><\/p>\n<p><span style=\"color: #000000;\"><strong>Neural networks work in a similar way. <\/strong>They are trained on a set of data, and as they are trained, they learn to recognise patterns in the data.
