It also proposes a taxonomy for imbalanced regression approaches based on three crucial criteria: regression model, learning process, and evaluation metrics. The study offers new insights into the use of such strategies, highlighting the advantages they bring to each model's learning process, and ...
Here, we introduce principled resampling strategies that preserve the tissue-animal hierarchy of individual replicates and compute the uncertainty of multidimensional decompositions applied to global averages. Using molecular鈥損henotypic data from the mouse aorta and colon, we find that interpretation of...

ized regression weight c (Figure 1A). The total effect of X on Y can be expressed as the sum of the direct and indirect effects: c 5 c′ 1 ab. Equivalently, c′ is the difference be- tween the total effect of X on Y and the indirect effect of ...
Variable iterative space shrinkage approach (VISSA) is an important variable selection algorithm known for its improved accuracy and outcome stability in partial least squares (PLS) regression models. However, time efficiency of VISSA is not very promising. In this work, three strategies to inflate ...
This way, we have showed that resampling strategies eliminated the need for additional datasets for the assessment of predictive capabilities of models. We used those two approaches within a Smooth Principal Components Analysis (SPCA)-based comparative approach for the invalidation of models. Our ...
Although the aforementioned methods follow different strategies to create or remove data samples, many of them rely on retrieving information from their neighbors. Since most MLDs have hundreds or even thousands of features, as well as a similar number of instances, finding k nearest neighbors for ...

We extend the application of resampling strategies to the time series context and introduce the concept of temporal and relevance bias in the case selection process of such strategies, presenting new proposals. We evaluate the results of standard regression tools and the use of resampling strategies,...
