1a) Given three attributes colour (red/green/yellow), size (large/medium/small) and texture (crisp creamy/juicy) of apples with corresponding degrees of ripeness (early/middle/late) as the output, use Nave Bayes to estimate the degree of ripeness for an apple of green, small, cream). Algorithmic descriptions are sufficient.

Algorithmic descriptions are sufficient. (15 marks) 1b) A decision tree uses estimates and probabilities to calculate likely outcomes, and helps someone to decide whether or not the gain from a decision is worthwhile. Use decision trees to design an algorithm for face detection in two-dimensional grey-scale images. (15 marks)
