A hybrid method to select morphometric features using tensor completion and F-score rank for gifted children identification

چکیده
Gifted children are able to learn in a more advanced way than others, probably due neurophysiological differences the communication efficiency neural pathways. Topological features contribute understanding correlation between brain structure and intelligence. Despite decades of neuroscience research using MRI, methods based on region connectivity patterns limited by MRI artifacts, which therefore leads revisiting morphometric features, with aim them directly identify gifted instead connectivity. However, small, high-dimensional feature dataset outliers makes task finding good classification models challenging. To this end, hybrid method is proposed that combines tensor completion selection handle then select discriminative features. The can achieve accuracy 93.1%, higher other existing algorithms, thus suitable for small datasets supervised scenarios.

Beyond Low Rank: A Data-Adaptive Tensor Completion Method
Low rank tensor representation underpins much of recent progress in tensor completion. In real applications, however, this approach is confronted with two challenging problems, namely (1) tensor rank determination; (2) handling real tensor data which only approximately fulfils the low-rank requirement. To address these two issues, we develop a data-adaptive tensor completion model which explici...
متن کاملEfficient tensor completion: Low-rank tensor train
This paper proposes a novel formulation of the tensor completion problem to impute missing entries of data represented by tensors. The formulation is introduced in terms of tensor train (TT) rank which can effectively capture global information of tensors thanks to its construction by a wellbalanced matricization scheme. Two algorithms are proposed to solve the corresponding tensor completion p...
متن کاملTensor completion using total variation and low-rank matrix factorization
In this paper, we study the problem of recovering a tensor with missing data. We propose a new model combining the total variation regularization and low-rank matrix factorization. A block coordinate decent (BCD) algorithm is developed to efficiently solve the proposed optimization model. We theoretically show that under some mild conditions, the algorithm converges to the coordinatewise minimi...
متن کاملA New Low-Rank Tensor Model for Video Completion
In this paper, we propose a new low-rank tensor model based on the circulant algebra, namely, twist tensor nuclear norm or t-TNN for short. The twist tensor denotes a 3-way tensor representation to laterally store 2D data slices in order. On one hand, t-TNN convexly relaxes the tensor multi-rank of the twist tensor in the Fourier domain, which allows an efficient computation using FFT. On the o...
