Some suggestions

Hi Ke, Thanks for the write up on Neural Net. It provided many insights, however I have few suggestions, which may help in clarifying few things better:

• The examples you used to describe neural nets, contain directed edges. However it is not explicitly not made clear, what these directions imply
• You have given few examples of activation functions, but there use is not made clear. Providing a comparison of those function and in what context should which one be used will help readers to understand them better
• Neural nets while being powerful by providing a choice of different activation function, are also prone to over fitting. A small section on that trade of and best practices used in that setting may be added to help realizing the full potential of neural net over other models.
• Looks like the figure number 1.6 is missing
• The last section of where neural nets are used does not provide much insight. A one line description against those application areas can mitigate this
• I dont see any other pages linked both internal and external. So adding few of them will help interested readers to learn more about those
• The builds on and more general than sections are not edited. In case you feel like nothing to add there, then you may remove the texts.

best, Prithu Banerjee

Hi Prithu, thanks for your critique and suggestions. I have added Figue 1.6 and some links to Wikipedia, and edited Builds on and More general than sections.
