ensembles

Ensembles are groups that operate as a coordinated unit. The term is used in performing arts to refer to a group of artists who perform together, and in science and statistics to describe methods that combine multiple components into one result.

In music, an ensemble is a group of musicians intended to produce a unified sound. Small ensembles include trios, quartets, and quintets; larger ones include chamber orchestras, concert bands, and choirs. Ensembles differ in size, repertoire, and performance practice, but succeed through balance, blend, and precise coordination.

In theater and film, an ensemble can describe a cast in which multiple performers share emphasis and screen time rather than a single star, enabling collaborative storytelling.

In fashion, an ensemble is a coordinated outfit or look, assembled from clothing and accessories designed to be worn together.

In statistics and machine learning, ensemble methods combine the predictions of multiple models to improve accuracy. Techniques such as bagging, boosting, and stacking are common. Ensembles can reduce variance, bias, or both, and they are widely used in predictive analytics.
