A classifier-guided sampling (CGS) method is introduced for solving engineering design optimization problems with discrete and/or continuous variables and continuous and/or discontinuous responses. The method merges concepts from metamodel-guided sampling and population-based optimization algorithms. The CGS...
当加了classifier guided相当于将 \mu_{\theta}(x_t, t) 向预测类别为 y 的方向更新了一小步。 s 是控制更新的幅值。 \begin{eqnarray} x_{t-1} &=& \mu_{\theta}(x_t, t) + s\nabla_{x_t} \log p_{\phi} (y|x_t)|_{x_t = \mu_{\theta}(x_t, t)} + \sigma(t) \epsilo...
Classifier-free guidance on ImageNet 64x64. Left: random classes. Right: single class (malamute). Same random seeds used for sampling in each subfigure. Classifier-free guidance on 128x128 ImageNet. Left: non-guided samples, right: guided samples with w = 3.0. Interestingly, strongly guided ...
LGBMClassifier stands for Light Gradient Boosting Machine Classifier. It uses decision tree algorithms for ranking, classification, and other machine-learning tasks. LGBMClassifier uses a novel technique of Gradient-based One-Side Sampling (GOSS) and Exclusive Feature Bundling (EFB) to handle large-sca...

In order to select the most informative genes in this subset, we used 1000 iterations of a random forest classifier sampling 70% of the RNA-seqs at each iteration (Fig. 1A). As a measure of each gene’s importance we use the mean decrease in accuracy (MDA), representing how much accura...
Krawczyk et al. introduced the Multi-Class Radial-Based Oversampling (MC-RBO) approach (Krawczyk et al., 2020). This method generates artificial instances using a latent function, guided by exploring regions with minimal between-class distribution values. MC-RBO effectively handles difficultdata dist...
