Functional Connectivity Evaluation for Infant EEG Signals based on Artificial Neural Network
The employment of the brain signals
electroencephalography (EEG) could supply a deep intuitive
understanding for infants behaviour and their alertness level
within the living environment. The study of human brain
through a computer-based approach has increased significantly
as it aiming at the understanding of infants’ mind and measure
their attention towards the surrounding activities. The artificial
neural network achieved a significant level of success in different
fields such as pattern classification, decision making, prediction,
and adaptive control by learning from a set of data and construct
weight matrices to represent the learning patterns. This research
study proposes an artificial neural network based approach to
predict the rightward asymmetry or leftward asymmetry which
reflects higher frontal functional connectivity in the frontal right
and frontal left, respectively within infant’s brain. In the
traditional methods, the value of asymmetry of the frontal (FA)
functional connectivity is used to determine the rightward or the
leftward asymmetry. While the proposed approach is trying to
predict that without going through all the levels of the calculation
complexity. The achieved work will supply a deep understanding
into the deployment of the functional connectivity to provide
information on the interactions between different brain regions
Statistical Methods and Artificial Neural Networks
Artificial Neural Networks and statistical methods are applied on real data sets for forecasting, classification, and clustering problems. Hybrid models for two components are examined on different data sets; tourist arrival forecasting to Turkey, macro-economic problem on rescheduling of the countries’ international debts, and grouping twenty-five European Union member and four candidate countries according to macro-economic indicators
Direction set based Algorithms for adaptive least squares problems improvements and innovations.
The main objective of this research is to provide a mathematically tractable solutions to the adaptive filtering problem by formulating the problem as an adaptive least squares problem. This approach follows the work of Chen (1998) in his study of direction-set based CDS) adaptive filtering algorithm. Through the said formulation, we relate the DS algorithm to a class of projection method.
Objektif utama penyelidikan ini ialah untuk menyediakan penyelesaian matematik yang mudah runut kepada masalah penurasan adaptif dengan memfonnulasikan masalah tersebut sebagai masalah kuasa dua terkecil adaptif. Pendekatan ini rnengikut hasil kerja oleh Chen (1998) dalam kajian beliau tentang algoritma penurasan adaptif berasaskan 'direction-set' (DS). Melalui fornulasi tersebut, kami menghubungkaitkan algoritma DS kepada satu kelas kaedah unjuran. Secara khususnya, versi rnudah aigoritma itu, iaitu algoritma 'Euclidean direction search' (EDS) ditunjukkan mempunyai hubungkait dengan satu kelas kaedah berlelaran yang dipanggil kaedah 'relaxation'. Penernuan ini rnembolehkan kami menambahbaik algoritma EDS kepada 'accelerated EDS' eli mana satu parameter pemecutan diperkenalkan untuk rnengoptirnumkan saiz langkah sernasa setiap pencarian garis
