Look at the world around you. You can make sense of many aspects of it. Take it a little further, you can predict a fairly good amount of it. For instance, grey clouds cover the sky — you automatically make the prediction that it will rain. That is an example of a very simply model. The input was visual data, the processing was the validation of the condition that there are grey clouds in the sky, and the output was a prediction that there will be rain. This model is a qualitative one. To make it of more use we quantify it.
