'''Progress and Status this week:'''
# Research on Trigram Markov model
# Two models are proposed:
#* Simple Trigram Markov model: only consider the effect of trigram in the text
#* Potential problem with first model: sparse data, new trigram appears in the test text, lead to poor cross entropy
#* Second model: Hidden Markov model on trigram: Not only count on trigram, but also unigram and bigram effects are taken into consideration. The transition probability is consisted from all three probabilities.
# The existence of punctuation and uppercase letter should be considered for text written in English.
# Programming on text file input and exception handle in JAVA

'''Plan and Goals for new week:'''
# Discuss the models with supervisor
# SVM problem
# Programming on first model
