WEBLearn how to optimize multiple reaction monitoring (MRM) conditions for liquid chromatographic-tandem mass spectrometric (LC/MS/MS) methods using Agilent MassHunter Optimizer software. This technical overview covers precursor and product ion selection, collision energy optimization, and practical considerations for triggered MRM (tMRM) methods.
WEBScout triggered MRM (stMRM) is a mode of operation for mass spectrometry in LC-MS/MS workflows that uses marker transitions to trigger MS analysis for dependent target analytes. Learn how stMRM removes the need to maintain accurate retention times, improves data quality and flexibility, and allows cross-experiment triggering.
WEBLearn how to use triggered MRM and online dilution for improved pesticide residue identification and sensitivity in food and feed samples. The method covers about 450 analytes with 0.01 mg/kg LOQ and validated in multiple matrices.

Minimum redundancy feature selection - Wikipedia
WEBMinimum redundancy feature selection is an algorithm frequently used in a method to accurately identify characteristics of genes and phenotypes and narrow down their relevance and is usually described in its pairing with relevant feature selection as Minimum Redundancy Maximum Relevance (mRMR).
Unveiling MRMR: Maximizing Relevance, Minimizing Redundancy …
WEBJan 1, 2024 · The crux of the MRMR algorithm lies in its objective: maximize feature relevance to the classification task while minimizing redundancy among the chosen features. For categorical variables,...
WEBA recent development is the Minimum Redundancy Maximum Relevance (mRMR) feature selection. Here the redundancy among the features in the subset are minimized while the relevance are maximized. An efficient algorithm computes the solution of these dual objective optimization problem.
Minimum redundancy maximum relevance feature selection …
WEBJan 3, 2017 · TMRMR is a filter-based method that selects features based on maximum relevance and minimum redundancy criteria. It handles multivariate temporal data without data flattening and outperforms alternatives in gene expression studies.
WEBWe developed an unsupervised minimum redundancy maxi-mum relevance feature selection method for predictive main-tenance applications by adapting the conventional mRMR al-gorithm where the relevance of a feature is computed with respect to prognostic metrics instead of class labels.
