A Non-Equidistant Elastic Net Algorithm
1997The statistical mechanical derivation by Simic of the Elastic Net Algorithm (ENA) from a stochastic Hopfield neural network is criticized. In our view, the ENA should be considered a dynamic penalty method. Using a linear distance measure, a Non-equidistant Elastic Net Algorithm (NENA) is presented.

Robust Elastic-Net Subspace Representation
IEEE Transactions on Image Processing, 2016Recently, finding the low-dimensional structure of high-dimensional data has gained much attention. Given a set of data points sampled from a single subspace or a union of subspaces, the goal is to learn or capture the underlying subspace structure of the data set.

Elastic net for paralinguistic speech recognition
Proceedings of the 14th ACM international conference on Multimodal interaction, 2012Given the fact that the length of the feature vector that is being used for the paralinguistic recognition of speech has exceeded some thousands, the importance of a sparse representation of a model becomes notable. The importance of a sparse representation is mainly due to the more interpretability, higher generalization capability, and numerically ...

Topology-Preserving Elastic Nets
2001We have developed a topology-preserving elastic net which combines both lateral and synaptic interactions to obtain topologically ordered representations (receptive fields) of an external stimulus. Existing neural models that preserve the topology by utilizing lateral interactions, such as the Kohonen map and Goodhill's mapping, and by utilizing ...

Operational issues of sequencing with elastic nets
Artificial Intelligence in Engineering, 2000Abstract The usefulness of the elastic net (EN) approach for the general sequencing problem is investigated. Initial parameter setting and subsequent adjustments need to be intelligently undertaken for various applications. Based on the experiments on the typical traveling salesman problem, helpful guidelines were suggested.

Time elastic digital systems and Petri Nets
2008 8th International Conference on Application of Concurrency to System Design, 2008Summary form only given. Digital electronic systems typically uses synchronous clocks and primarily assume fixed duration of their operations to simplify the design process. Time elastic systems can be constructed either by replacing the clock with communication handshakes (asynchronous version) or by augmenting the clock with a synchronous version of ...

A robust elastic net approach for feature learning
Journal of Visual Communication and Image Representation, 2014Unsupervised feature learning has drawn more and more attention especially in visual representation in past years. Traditional feature learning approaches assume that there are few noises in training data set, and the number of samples is enough compared with the dimensions of samples.

Elastic nets, travelling salesmen and cortical maps
Current Biology, 1992Hubel and Wiesel [ 1 ] were the first to show that many neuronal response properties vary systematically with position on the surface of the primate visual cortex. Not 0nly are these so-called maps highly ordered, but recent results obtained by direct imaging of neuronal activity patterns with voltage-sensitive dyes [2,3], have shown that the different

Bayesian Elastic Net Tobit Quantile Regression
Communications in Statistics - Simulation and Computation, 2014In this article, the problem of parameter estimation and variable selection in the Tobit quantile regression model is considered. A Tobit quantile regression with the elastic net penalty from a Bayesian perspective is proposed. Independent gamma priors are put on the l1 norm penalty parameters.
