On the Problem of Computing the Probability of Regular Sets of Trees [PDF]

open access: yes, 2015
We consider the problem of computing the probability of regular languages of infinite trees with respect to the natural coin-flipping measure. We propose an algorithm which computes the probability of languages recognizable by \emph{game automata}.

Power of Randomization in Automata on Infinite Strings [PDF]

open access: yesLogical Methods in Computer Science, 2011
Probabilistic B\"uchi Automata (PBA) are randomized, finite state automata that process input strings of infinite length. Based on the threshold chosen for the acceptance probability, different classes of languages can be defined.

Quotient Complexities of Atoms in Regular Ideal Languages [PDF]

open access: yes, 2015
A (left) quotient of a language $L$ by a word $w$ is the language $w^{-1}L=\{x\mid wx\in L\}$. The quotient complexity of a regular language $L$ is the number of quotients of $L$; it is equal to the state complexity of $L$, which is the number of states ...

Query learning of derived $\omega$-tree languages in polynomial time [PDF]

open access: yesLogical Methods in Computer Science, 2019
We present the first polynomial time algorithm to learn nontrivial classes of languages of infinite trees. Specifically, our algorithm uses membership and equivalence queries to learn classes of $\omega$-tree languages derived from weak regular $\omega ...

Efficient Algorithms for Morphisms over Omega-Regular Languages [PDF]

open access: yes, 2015
Morphisms to finite semigroups can be used for recognizing omega-regular languages. The so-called strongly recognizing morphisms can be seen as a deterministic computation model which provides minimal objects (known as the syntactic morphism) and a ...

Families of DFAs as Acceptors of $\omega$-Regular Languages [PDF]

open access: yesLogical Methods in Computer Science, 2018
Families of DFAs (FDFAs) provide an alternative formalism for recognizing $\omega$-regular languages. The motivation for introducing them was a desired correlation between the automaton states and right congruence relations, in a manner similar to the ...

Syntactic structures of regular languages [PDF]

open access: yesTheoretical Computer Science, 2019
We introduce here the notion of syntactic lattice algebra which is an analogy of the syntactic monoid and of the syntactic semiring. We present a unified approach to get those three structures.

Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...

Regular Languages in the Sliding Window Model [PDF]

open access: yesTheoretiCS
We study the space complexity of the following problem: For a fixed regular language $L$, we receive a stream of symbols and want to test membership of a sliding window of size $n$ in $L$.

Using Data Mining Algorithms to Discover Regular Sound Changes among Languages [PDF]

open access: yesMATEC Web of Conferences, 2019
This paper presents a method of using association rule data mining algorithms to discover regular sound changes among languages. The method presented has a great potential to facilitate linguistic studies aimed at identifying distantly related cognate ...
