What is ensemble?

An ensemble is a group of individuals or entities that come together to form a unified whole. In the context of music, an ensemble is a group of musicians playing together as one entity. Ensembles can range from small chamber groups, such as string quartets or brass quintets, to large orchestras with dozens or even hundreds of players.

Ensembles can also be vocal groups, such as choirs or a cappella groups. Dance ensembles feature multiple dancers performing together, often in sync. Acting ensembles may also refer to a group of performers working together on stage or in film.

In data science, ensemble learning is a technique in which multiple machine learning models are combined to improve the accuracy of predictions or classifications. The individual models may use different algorithms or parameters to generate their predictions, and the final output is determined by a combination of these predictions.

Overall, ensembles in various fields have the common goal of bringing together the strengths of multiple individuals or entities to achieve a greater impact than any one can achieve alone.
