Latest updates on Dimensionality reduction part2(Machine Learning 2024)
- A supervised dimensionality reduction method called Gradient Boosting Mapping (GBMAP) is proposed to find a good set of features or distance measures in supervised learning.
- GBMAP uses the outputs of weak learners to define the embedding, which provides better features for the learning task.
- The embedding coordinates automatically ignore irrelevant directions and can be used to find a principled distance measure between points.
- GBMAP is fast and performs well in regression and classification tasks compared to state-of-the-art methods.

Latest updates on Dimensionality reduction part1(Machine Learning 2024)
- Intracellular protein patterns regulate vital cellular functions by coupling protein dynamics on the cell membrane to dynamics in the cytosol.
- Recent studies have shown that modeling cytosolic dynamics without considering concentration gradients normal to the membrane may overlook crucial aspects of pattern formation.
- A generic framework has been developed to project cytosolic dynamics onto the lower-dimensional surface, accounting for cytosolic concentration gradients in both static and evolving geometries.
- This framework utilizes a small number of dominant characteristic concentration profiles, similar to basis transformations of finite element methods, to approximate the cytosolic dynamics.

Research on Bidiagonalization part8(Machine Learning future)
- The k-step Lanczos bidiagonalization reduces a matrix A∈Rm×n into a bidiagonal form Bk∈R(k+1)×k while generates two orthonormal matrices Uk+1∈Rm×(k+1) and Vk+1∈Rn×(k+1).
- Practical implementations of the algorithm suffer from loss of orthogonality of Uk+1 and Vk+1 due to rounding errors, leading to the proposal of reorthogonalization strategies.
- A backward error analysis of the Lanczos bidiagonalization with reorthogonalization (LBRO) shows that the computed Bk is the exact one generated by the k-step Lanczos bidiagonalization of A+E with certain perturbations.
- The orthogonality levels of Uk+1 and Vk+1 determine the stability of the k-step LBRO, which has implications for SVD computation and LSQR algorithms.

Dynamics of Regularized regression part4(Machine Learning 2024)
- Calibration of machine learning classifiers is necessary to obtain reliable and interpretable predictions.
- Isotonic regression (IR) is a technique used for calibrating binary classifiers by minimizing cross-entropy on a calibration set.
- IR preserves the convex hull of the ROC curve, ensuring calibration without overfitting the calibration set.
- A novel generalization of isotonic regression is presented to accommodate classifiers with K classes, achieving multi-class calibration error of zero.

Revisiting Multiclass Classification part2(Machine Learning 2024)
- Designing proper treatment plans for managing diabetes in older adults with Type 2 Diabetes Mellitus (T2DM) is crucial, considering their remaining life and comorbidities.
- A structured dataset with 68 potential mortality predictors for 275,190 diabetic U.S. military veterans aged 65 years or older is used in this study.
- Multiple classifiers like Multinomial Logistic Regression, Random Forest, XGBoost, and One-vs-Rest are employed, but all the models consistently underperform.
- The high dimensionality of the input data after dummy encoding and the association of input variables with multiple target classes contribute to misclassifications.
