Learning from Uncurated Regular Expressions [PDF]
Significant work has been done on learning regular expressions from a set of data values. Depending on the domain, this approach can be very successful. However, significant time is required to learn these expressions and the resulting expressions can become either very complex or inaccurate in the presence of dirty data.

Partial Derivative Automaton for Regular Expressions with Shuffle [PDF]
We generalize the partial derivative automaton to regular expressions with shuffle and study its size in the worst and in the average case. The number of states of the partial derivative automata is in the worst case at most 2^m, where m is the number of

Deterministic automata for extended regular expressions
In this work we present the algorithms to produce deterministic finite automaton (DFA) for extended operators in regular expressions like intersection, subtraction and complement.

Pattern Matching in YARA: Improved Aho-Corasick Algorithm
YARA is a tool for pattern matching used by malware analysts all over the world. YARA can scan files, as well as process memory. It allows us to define sequences of symbols as text strings, hexadecimal strings and regular expressions. However, the use of

Flowchart Programs, Regular Expressions, and Decidability of Polynomial Growth-Rate [PDF]
We present a new method for inferring complexity properties for a class of programs in the form of flowcharts annotated with loop information. Specifically, our method can (soundly and completely) decide if computed values are polynomially bounded as a ...
