Identification of the harmonic transfer functions of a helicopter rotor
… The system identification scheme employs a least square estimation technique to obtain HTF estimates. This least square estimation problem is under-determined; therefore, an additional assumption, that the transfer function is smooth, is made in the ID scheme to achieve a well-posed problem. …

Hybrid intensity and time-of-flight signal processing techniques for intelligent distance sensors
… such as the use of differentiated signals, least square estimation, and optimization algorithms are introduced and applied to the object model. A range of techniques based on specific use cases are developed, and their capabilities and limitations are discussed. Results show that in a …

A generalized rule-based short-term load forecasting technique
… and then utilizes regression to obtain the least-square estimation of the load. Because it uses the pairwise comparison technique, it is fairly robust. Since the forecast does not depend on any preset model, the technique is inherently updatable. A generalized version of the technique has …

Portfolio management using computational intelligence approaches. Forecasting and Optimising the Stock Returns and Stock Volatilities with Fuzzy Logic, Neural Network and Evolutionary Algorithms.
… models are also usually impaired by the estimation error problem caused by lack of ability to predict the future accurately. A number of Multi-Objective Genetic Algorithms are proposed to solve the problem with two objectives subject to cardinality constraints, floor constraints and …

Modified anfis architecture with less computational complexities for classification problems
… and combination of gradient descent (GD) and least square estimation (LSE) which have problem to be likely trapped in local minima. Even though grid partitioning method is very useful to generate better accuracy for ANFIS model, since it generates maximum number of rules by considering all …

Target Tracking Via Marine Radar
… uses a set of particles with various weights for estimation. However, particle filters have high computation time. Kalman and particle filters were developed over the years creating various models for various types of systems. A block version of Compressive Matching Pursuit (CoSaMP) algorithm used …

Multimodal Indexing of Presentation Videos
… PTZ camera movement, which is computed through least square estimation starting from the luminance constancy assumption. A local features based stitching algorithm is then applied to estimate the homography among a set of video frames and median blending is used to render pixels in overlapping …

Robust mixtures of regression models
… project, we demonstrate that the MLE, like the least squares estimate, is sensitive to outliers and heavy-tailed error distributions. We propose a robust estimation procedure and an EM-type algorithm to estimate the mixture regression models. Using a Monte Carlo simulation study, we demonstrate …

Modeling and Analysis of Synchronization Schemes for the TDMA Based Satellite Communication System
… may result in difficulty of signal detection and estimation. Comparing with SC systems, OFDM systems are more sensitive to synchronization errors, because these errors will lead to inter-symbol interference (ISI) and inter-carrier interference (ICI). Although many synchronization algorithms have …
