Hello,
I want to use a node that represents the geographical location of an event.
I need longitude/latitude to descibe the location. I would partition the space in rectangles:
lat between y1 and y2 and long between x1 and x2; ...
But the tables in the general tab only has one dimension for the states.
Does it mean that I have to enter states like:
state 1: lat between y1 and y2, long between x1 and x2
state2: lat between y2 and y3, long between x1 and x2
...
Is there no way to make it really two-dimensional because it resulte in very many staers to make one state for every combination of lat/long?
best regards
multidimensional states

Re: multidimensional states
What about creating two variables, one for latitude and for longitude ?samoht wrote:I want to use a node that represents the geographical location of an event.

Hi Marek,
I also thought about this. I want to use test data to learn the parameters of my BN. one parameter of a test data set is the lat/long-coordinate.
Doesn't it make a difference for the result of the parameter learning whether I train the BN with a coupled lat/long pair as one single variable or with two separate variables for lat and long?
Best Regards Thomas
