Assignment 4: Question 7

After going through the tedious process of working out the information gain for each factor I got to the point of drawing the decision tree. At the the bottom-most attribute was weight for me, but this means that there are two leaves of that attribute that do not lead to a 'yes' or 'no' answer.

Has anyone managed to get all of the paths to yes and no decisions?

I also got weight as the attribute with the least information gain.

I managed to draw my decision tree, but I I ended up not using the weight or height attributes in the tree. Mine lead to yes/no only using the other two attributes. Unless I have missed something, I think it does still work. (effectively - weight and height have no impact on if the person got burnt or not)..

Oh of course! That makes sense - I had forgotten that you don't need to put all the attributes in.

Thank you smiling smiley
