# Projector **`class Projector(config)`** Bases: [`BatchedStep`](../technical/libnlp/steps/standard.md#squirro.lib.nlp.steps.batched_step.BatchedStep) The [`Projector`](#squirro.lib.nlp.steps.projectors.Projector) step projects from one vector space to another. The usual result is that vectors of numbers become smaller vectors of numbers, and thus easier to work with. Parameters - `step` ([`str`](https://docs.python.org/3.11/library/stdtypes.html#str)) – projector - `type` ([`str`](https://docs.python.org/3.11/library/stdtypes.html#str)) – Type of [`Projector`](#squirro.lib.nlp.steps.projectors.Projector) - `input_field` ([`str`](https://docs.python.org/3.11/library/stdtypes.html#str)) – Field to project - `output_field` ([`str`](https://docs.python.org/3.11/library/stdtypes.html#str)) – Field to write projection
