Chinese dialect tone’s recognition using gated spiking neural P systems
Journal of Membrane Computing - Tập 4 - Trang 284-292 - 2022
Tone is the changing trend of pitch with time. In Chinese, tone plays an essential role for distinguishing meaning. Chinese dialect’s tone is more complex with Mandarin. In the field of Chinese dialect phonetics research, using human earing to recognize the types of tones is still the main method. So batch processing is not possible. In this paper, we construct a GSNP (gated spiking neural P) mode...... hiện toàn bộ
Computing with SN P systems with I/O mode
Journal of Membrane Computing - Tập 2 - Trang 230-245 - 2020
P systems were introduced more than two decades ago by Gheorghe Pǎun. They are known as nondeterministic maximally parallel computing models. Most of their variants are proved to be capable of solving NP problems in polynomial time. This work focuses on using neural-like P systems to simulate uniform sequential computing models. In particular, we consider a so-called Spiking Neural P module (SN P ...... hiện toàn bộ
Networks of splicing processors: simulations between topologies
Journal of Membrane Computing - Tập 5 - Trang 108-115 - 2023
Networks of splicing processors are one of the theoretical computational models that take inspiration from nature to efficiently solve problems that our current computational knowledge is not able to. One of the issues restricting/hindering is practical implementation is the arbitrariness of the underlying graph, since our computational systems usually conform to a predefined topology. We propose ...... hiện toàn bộ
P systems with limited number of objects
Journal of Membrane Computing - Tập 3 - Trang 1-9 - 2021
P systems are a model of compartmentalized multiset rewriting inspired by the structure of living cells and the way they function. In this paper, we focus of a variant in P systems in which membranes have limited capacity, i.e., the number of objects they may hold is limited by a fixed bound. This feature corresponds to an important physical property of cellular compartments. We propose several po...... hiện toàn bộ
Turing universality of sequential spiking neural P systems with polarizations as number accepting devices
Journal of Membrane Computing - Tập 4 - Trang 232-242 - 2022
To take full advantage of the information transfer mechanism of biological nervous systems, we consider a new computational model of spiking neural P systems with polarizations (PSN P systems). Compared to spiking neural P systems (SN P systems), PSN P systems use more simple formal language rules, and the behavioral changes of each neuron are jointly controlled by the number of spikes and the pol...... hiện toàn bộ
Inference of bounded L systems with polymorphic P systems
Journal of Membrane Computing - Tập 1 - Trang 52-57 - 2019
In this paper, we are going to solve the inference problem of bounded L systems, namely such L systems which work on filaments having length up to a fixed size. We will show that these bounded L systems have considerable computational power as they can simulate linear-bounded automata. To carry out the inference, we are going to construct a specific polymorphic P system with target indication, whi...... hiện toàn bộ
Bounding the space in P systems with active membranes
Journal of Membrane Computing - Tập 2 - Trang 137-145 - 2020
P systems with active membranes have been widely used to attack problems in $${\mathbf{NP}}$$ or even in $${{\mathbf{PSPACE }}}$$; in general, an exponential amount of space is generated in polynomial time by dividing existing membranes. Natural questions arise in this framework, concerning the power of P systems when different bounds are considered for the use of the space resource. We consider i...... hiện toàn bộ
Search-based testing in membrane computing
Journal of Membrane Computing - Tập 1 - Trang 241-250 - 2019
Search-based testing is widely used for generating test sets. It is also applied in the case of model-based testing, especially for (extended) finite state machines. In this paper, we define such an approach for kernel P system models. We consider a specific kernel P system model and a define a search-based testing method. The test set generated consists of input sequences producing a given comput...... hiện toàn bộ
An improved universal spiking neural P system with generalized use of rules
Journal of Membrane Computing - Tập 1 - Trang 270-278 - 2019
Taken inspiration from biological phenomenon that neurons communicate via spikes, spiking neural P systems (SN P systems, for short) are a class of distributed and parallel computing devices. So far firing rules in most of the SN P systems usually work in a sequential way or in an exhaustive way. Recently, a combination of the two ways mentioned above is considered in SN P systems. This new strate...... hiện toàn bộ
