----------------------------------
Hi Jesse,
* In your draft you have phrased it using "we". Once you do the work thats the
right thing to say. But this is a proposal you as in indiviual are applying to
GSoC, so I suggest using "I" instead.
* Can you indicate how at the end of each milestone (the two week period) the
demonstrations will be? I mean you need to write instruction by means working
example at end of the milestone so others can get upto speed.
* Can you also include in your timeline, time for you to write documentation to
the code and also unit level test coverage? You should not wait for these to
the end, but do it on a ongoing basis.

> Develop Hidden Markov Model to predict criminal moments

> Key: SIS-324

> The proposed project extends https://issues.apache.org/jira/browse/SIS-97.
> The Agent based modelling project during GSoC 2013 used a probabilistic model
> that was hardcoded. It served as the basis to predict criminal’s movements
> which infer crimes. This proposed project should do the inverse. Predict the
> probabilistic model that controls the criminals’ behavior using data about
> his movements and crimes.
> The project should be preliminary work for data mining. From a sample
> anonymised emergency call (911 data) a criminal should be uniquely
> identified. Hidden Markov Model, a probabilistic state transition system,
> i.e., we define states such as “at home”, “in office etc”, “roaming mode”
> etc, and there are probabilistic transitions between them. We can associate
> some behavior to a particular state. Thus, the probabilistic model that was
> hardcoded by Nadeem (in GSOC 2013) was a Markov model (this is a little
> indirectly). When we only have the crime data and we want to find the model
> that dictates the criminal’s behavior, the Markov model is hidden to us.
> There are algorithms that can do this. These algorithms need to have their
> parameters set by humans – such as the number of states. So this would need
> some amount of experimentation.
