A Simple Feature Augmentation for Domain Generalization
openaccess.thecvf.com2.3. Domain Randomization Domain randomization has been widely used in differ-ent tasks [34,43,31,31,42,26] in computer vision. [34] firstly proposed to apply diverse random rendering styles to synthetic data, such that the test data was likely to lie within the training distribution, thus improving generaliza-tion.
Monte Carlo Integration
cs.dartmouth.eduLas Vegas algorithms are another class of method which rely on randomization to compute their results. However, in contrast to Las Vegas algorithms, which always produce the exact or correct solution, the accuracy of Monte Carlo methods can only be analyzed from a statistical viewpoint.

Skip Lists - Carnegie Mellon School of Computer Science
www.cs.cmu.eduRandomization • Allows for some imbalance (like the +1 -1 in AVL trees) • Expected behavior (over the random choices) remains the same as with perfect skip lists. • Idea: Each node is promoted to the next higher level with probability 1/2-Expect 1/2 the nodes at level 1-Expect 1/4 the nodes at level 2• Therefore, expect # of nodes at each level is the same as
RANDOMIZED COMPLETE BLOCK DESIGN (RCBD)

Example Given four fertilizer rates applied to ‘Amidon’ wheat and three replicates of each treatment.
Randomization in Clinical Trial Studies - lexjansen.com
lexjansen.comA good clinical trial minimizes variability of the evaluation and provides an unbiased evaluation of the intervention by avoiding confounding from other factors. Randomization insures that each patient have an equal chance of receiving any of the treatments under study, generate comparable intervention groups which are alike in all
