Covariance matrix analysis in simultaneous localization and mapping by Nur Aqilah, Othman

“…However, this thesis has proven that the cross-correlation elements are important to ensure the accuracy of the estimation; hence it should be integrated in the diagonalization process. In EKF-based SLAM, measurement data are required at each time step to complete the estimation process. …”

A Karhunen Loeve Transform Approach for Recovering Evoked Potentials from Electroencephalograph by Yusoff, Mohd Zuki, Kamel , Nidal

“…The diagonalization process actually decomposes the contaminated EP into decorrelated components; the components which are excessively dominated by EEG noise are discarded, and the ones which are less affected by the noise are preserved. …”

A Subspace Approach for Extracting Signals Highly Corrupted by Colored Noise by Yusoff, Mohd Zuki, Hussin, Fawnizu Azmadi

“…Loizou, “A Generalized Subspace Approach for Enhancing Speech Corrupted by Colored Noise,” IEEE Transactions on Speech and Audio Processing, vol. 11, no. 4, pp. 334-341, July 2003] introduced a non-symmetric basis matrix to be eigen-decomposed into its corresponding eigenvalue and eigenvector matrices; the generated eigenvector matrix is supposed to simultaneously diagonalize both the clean speech and noise covariance matrices. …”

Communication pattern and decision making in Parti Keadilan Rakyat (the People’s Justce Party) Malaysia: Phenomenography approach by Priyowidodo, Gatut, Abu Bakar, Hassan, Mustaffa, Che Su

“…Research findings are; 1) the communication pattern in the People’s Justice Party covers the formal and informal communication pattern.Formal is upward and downward communication pattern.Informal included horizontal communication, cross channel/diagonal communication and grapevine communication.2.The process of decision making is determined by three factors context, experience and authority.Meanwhile, limitation of the study is, in general, qualitative research.First, this study is put on the interview.This means that researchers can in no way confirm that the information in the form of the story is true experience or manipulative.Human attitudes and actions can always be changed.Second, researchers have limitations in data access of the informant.Third, interpretation of data depends on the researcher.Fourth, informants were selected only from some members and leaders and thus cannot be claimed as representing the communication patterns implemented by everyone. …”

The performance of clustering approach with robust mm-estimator for multiple outlier detection in linear regression by Mohd. Azmi, Nurulhuda Firdaus, Midi, Habshah, Ismail, Noranita Fairus

“…As a result of the need to identify outliers, numerous outlying measures such as residuals and hat matrix diagonal are built. However, these outlying measures works well when a regression data set contains only a single outlying point and it is well established that regression real data sets may have multiple outlying observations that individually are not easy to identify by the same measures. …”

Prediction of Rainfall Trends Using Forecasting Approaches Based on Singular Spectrum Analysis by Kismiantini, Kismiantini, Shaharudin, Shazlyn Milleana, Setiawan, Ezra Putranda, Urwatul Wutsqa, Dhoriva, Ahmad Basri, Muhamad Afdal, Mahdin, Hairulnizam, A. Mostafa, Salama

“…The SSA steps for forecasting rainfall data include decomposition (embedding and singular value decomposition), reconstruction (grouping and diagonal averaging), and evaluating the SSA model using w-correlation (if w-correlation is close to zero, returning to the decomposition stage; otherwise, continue the process), forecasting, evaluating the forecast results using root mean square error (RMSE), mean absolute error, r, and mean forecast error, and finally selecting the best model (either the SSA-R or SSA-V model). …”
