2021 International Workshop on Intelligent Information Technologies & Systems of Information Security  
A stochastic game model of data clustering under interference conditions is proposed. An adaptive recurrent method and algorithm for stochastic game deciding have developed.  ...  For this purpose, each data point is considered as a separate player with the ability to learn and adapt to the uncertainties of the system.  ...  Introduction Clustering can accomplished by solving data mining and data visualization problems, grouping and pattern recognition, knowledge extraction and information retrieval, and object classification  ...

SERKET: An Architecture for Connecting Stochastic Models to Realize a Large-Scale Cognitive Model [article]

Tomoaki Nakamura, Takayuki Nagai, Tadahiro Taniguchi
2017 arXiv   pre-print
Conventionally, the equations for parameter estimation have to be derived and implemented depending on the models. However, it becomes harder to derive and implement those of a larger scale model.  ...  Therefore, Serket makes it easy to construct large-scale models and estimate their parameters via the connection of modules.  ...  Moreover,Ŝ is sent to the speech recognition model, and the parameter L of the language model is updated.  ...

The Stochastic complexity of spin models: Are pairwise models really simple? [article]

Alberto Beretta, Claudia Battistin, Clélia de Mulatier, Iacopo Mastromatteo, Matteo Marsili
2018 Entropy   accepted
In information theory and Bayesian inference, the simplicity of a model is precisely quantified in the stochastic complexity, which measures the number of bits needed to encode its parameters.  ...  In order to understand how simple models look like, we study the stochastic complexity of spin models with interactions of arbitrary order.  ...  Yet, problems such as image or speech recognition and language translation have shown that Big Data can solve problems without necessarily understanding them [1] [2] [3] .  ...

Measuring the perceptual availability of phonological features during language acquisition using unsupervised binary stochastic autoencoders

Cory Shain, Micha Elsner
2019 Proceedings of the 2019 Conference of the North  
In this paper, we deploy binary stochastic neural autoencoder networks as models of infant language learning in two typologically unrelated languages (Xitsonga and English).  ...  We show that the drive to model auditory percepts leads to latent clusters that partially align with theory-driven phonemic categories.  ...  All views expressed are those of the authors and do not necessarily reflect the views of the National Science Foundation.  ...

Stochastic modelling of transition dynamic of mixed mood episodes in bipolar disorder

Yashaswini Kunjali Ajeeth Kumar, Adithya Kishore Saxena
2022 International Journal of Power Electronics and Drive Systems (IJPEDS)  
According to the standard body, there are classification of discrete forms of bipolar disorder viz. type-I, type-II, and cyclothymic.  ...  Hence, the model contributes to obtain granular information with dynamics of mood transition.  ...  A discriminant classification over linear model of regression is designed to carry out this form of detection. Apart from detection-based approach, there is also recognition-based approach.  ...
