We propose an OT-theoretic typology of vowel harmony systems based on a comparative study of front/back harmony. Harmony processes are governed by a general constraint that imposes feature agreement on neighboring segments. Disharmonic (“neutral”) segments arise when this constraint is dominated by markedness constraints and/or by faithfulness constraints that govern segment inventories. These ...

Under the Bayesian Ying-Yang (BYY) harmony learning theory, a harmony function has been developed for Gaussian mixture model with an important feature that, via its maximization through a gradient learning rule, model selection can be made automatically during parameter learning on a set of sample data from a Gaussian mixture. This paper proposes two further gradient learning rules, called conj...

Harmony Search Algorithm originally came from the analogy between the music improvisation and optimization process. The harmony search algorithm is searching the optimal solution using the novel stochastic derivative equation. The equation is based on density information of multiple solution vectors, instead of calculus based gradient information of single solution vector. In other words, if a ...

This paper presents a new optimization algorithm called GHS+LEM, which is based on the Global-best Harmony Search algorithm (GHS) and techniques from the Learnable Evolution Models (LEM) to improve convergence and accuracy of the algorithm. The performance of the algorithm is evaluated with fifteen optimization functions commonly used by the optimization community. In addition, the results obta...

In this paper a hybrid genetic and harmony search algorithm is proposed to find the possible best sequence of operation solutions for hybrid flow shop scheduling problems. In this work the problem is considered with respect to the objective of minimization of makespan. Hybrid flow shop scheduling problem is considered for the sequencing of jobs in a hybrid flow shop with two or more identical m...

It would be great if interface residues, which are responsible for protein-protein interactions, could be determined from the amino acid sequence. Sequence Harmony, Multi-RELIEF, SDPpred and GroupSim+ConsWin are used to predict interface residues from residue conservation between interacting and non-interacting groups. Therefore, a dataset based on Fungal Orthologous Groups is used. Different a...

Music scholars have been intensively studying tonal harmony for centuries, yielding numerous theories and models. Unfortunately, a large number of these theories are formulated in a rather informal fashion and lack mathematical precision. In this article we present HarmTrace, a functional model of Western tonal harmony, which builds on well-known theories of tonal harmony. In contrast to many o...

Initially, it was believed that blocking effects1 simply could not be modeled with Agreement by Correspondence (ABC) (Hansson 2001; Rose & Walker 2004). Hansson, in particular, lays out this assumption very clearly: “Intervening segments do not themselves enter into the agreement relation holding between the trigger-target pair, and therefore they must be irrelevant to that relation: they canno...

The Harmony Search is a relatively new meta-heuristic algorithm for continuous optimization, in which its concept imitates the process of music improvisation. This paper proposes an improved harmony search algorithm called Harmony Search with Adaptive Pitch Adjustment (HSAPA). The adaptive pitch adjustment scheme during a search period is inspired from the velocity clamping in particle swarm op...
