I'm trying to solve a problem that requires me to simplify regular expressions. Here is the starting point: ( a a a) ∗ b ( b b b) ∗. Which I rewrote as follows: ( a 3) ∗ b ( b 3) ∗. However I've been trying to simplify it without success. Is there a way it could be simplified any further? WebbIn general, regular expressions are unsuited for classifying novel data. For any finite training set, you will get a RE/FSM that matches only the positive examples in that set, with no ability to generalize to new data. I've never seen an approach that attempts to find an infinite regular language that matches some training corpus. how many blocks are a mile

WebbThe easiest one is the "state removal technique." You remove a state and replace all the edges between states that were connected to the removed state with edges labeled with regular expressions. As you reduce in this way you eventually get to a regular expression for the whole DFA. (Note that Figure 4 in the paper I linked is not quite right. WebbNormalize text: Transform to lowercase, remove punctuation and accents and perform Unicode NFD normalization ( Café -> cafe ). Stem words: Transform each word into its “stem”, i.e. its grammatical root. For example, grammatical is transformed to grammat. This transformation is language-specific.
