This work explores the use of source-filter models for pitch salience estimation and their combination with different pitch tracking and voicing estimation methods for automatic melody extraction. Source-filter models are used to create a mid-level representation of pitch that implicitly incorporates timbre information. The spectrogram of a musical audio signal is modelled as the sum of the lea...

Successful multi-object tracking requires consistently maintaining object identities and real-time performance. This task becomes more challenging when objects are indistinguishable from one another. This paper presents a Bayesian framework for maintaining the identities of multiple objects. Our semi-independent joint motion model (SIMM) solves the coalescence and identity switching problem in ...

Stable isotope analysis of diet has become a common tool in conservation research. However, the multiple sources of uncertainty inherent in this analysis framework involve consequences that have not been thoroughly addressed. Uncertainty arises from the choice of trophic discrimination factors, and for Bayesian stable isotope mixing models (SIMMs), the specification of prior information; the co...

We investigate a special sequence of random variables $A(N)$ defined by an exponential power series with independent standard complex Gaussians $(X(k))_{k \geq 1}$. Introduced Hughes, Keating, and O'Connell in the study matrix theory, this relates to Gaussian multiplicative chaos (in particular "holomorphic chaos'' per Najnudel, Paquette, Simm) functions. Soundararajan Zaman recently determined...

This paper presents the smart interacting multiple model (SIMM) using the concept of predicted point and maximum noise level. Maximum noise level means the largest value of the mere noises. We utilize the positional difference between measured point and predicted point as acceleration. Comparing this acceleration with the maximum noise level, we extract the acceleration to recognize the charact...

To improve the dynamical behaviors of 1D chaotic maps, a new linear-delay-modulation method (LDM) is proposed. Derived from Sine map, delayed map (DSM) proposed based on LDM. Then, we substitute in SIMM system with DSM and obtained (DSIMM). Its performance analyzed through phase diagram, Lyapunov exponent spectrum, complexity. The results show that can generate more complex random sequences. He...

Change analysis (CA) is an investigation of an organisational situation in order to arrive at decisions concerning change measures. This means that CA should precede development of information systems and other change endeavours. The paper takes as its starting points earlier methods for change analysis (ISAC and SIMM). A need for a socio-pragmatic basis for CA is recognised. Such a basis shoul...

the main goal of this paper is to introduce and study a new class of function via the notions of $e$-$theta$-open sets and $e$-$theta$-closure operator which are defined by özkoç and aslım cite{10} called weakly $er$-open functions and $e$-$theta$-open functions. moreover, we investigate not only some of their basic properties but also their relationships with other types of already existing to...
