description of the main class: TransformationLearner
GENERATION PROCESS
We suppose a new point v is obtained from a point x by : 1) choosing a transformation t among a set of transformations T (with probability p(t)) 2) applying the choosen transformation t on x 3) add some noise in all the directions (noise = normally distributed random variable)
UNDERLYING PROBABILITY SPACE
variables of the distribution : X : real vector V : real vector, neighbor of X T : transformation P(x,v,t) = P(v is obtained by applying transformation t on x) = P(x,v|t)P(t) = N( T(t)(x)|v,sigma)P(t)
LEARNING BEHAVIOR
The parameters of the distributions are learned using a variant of E.M.algorithm
