 +===SHORT REPORT===
 +Intro
 +Autors said that training perceptron is quicker and easier solution.
 +Definition
 +We defined structured perceptron and parametres for special case of structured perceptron.
 +Parameters are log of conditional probability for trigram words and conditional probability for word and tag.
 +αx,y,z = log P(z | x,y)
 +αt,w = log P(w| t)
 +Logs are used for precision
 +Then speaker show how work process of learning.
 +Autors then deal with separable and inseparable data.
 +They defined condition for inseparable data.
 +
 +We spend rest of time solution of questions. During that solution were shown others fetatures of this percepton training.
