2d quantitative structure activity relationship modeling of methylphenidate analogues using algorithm and partial least square regression
… conformation. A genetic algorithm - partial least squares (GA-PLS) approach was used to identify the molecular descriptors that correlate to the biological activity (binding affinity) of a set of 80 methylphenidate analogues and to construct a predictive model. The GA code was implemented …

Sequential Calibration of Asset Pricing Models to Option Prices
… filtering methods are compared to the standard least square method (LSQ). The results show that both methods are capable of tracking the hidden state and time varying parameters with varying success. The non-linear filtering methods are faster and generally perform better on validation. To test …

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. …

Probabilistic models based on experimental observations using sparse bayes methodology
… through comparison with existing methods such as least-square method and penalized least-square method. The Sparse Bayes method is further developed to identify a few representative points in the parameter space by grouping the relevant vectors identified by the method using the k-means clustering …
