feature selectivity
[/ˈfiːtʃər sɪˈlɛktɪvɪti/]
noun
seletividade de características
1. The ability of a neuron or neural system to respond preferentially to specific features or attributes of a stimulus while ignoring others
The feature selectivity of visual cortex neurons allows them to respond strongly to oriented edges in specific directions.
A seletividade de características dos neurônios do córtex visual permite que respondam fortemente a bordas orientadas em direções específicas.
2. In machine learning and computer vision, the capacity of a model or algorithm to identify and prioritize relevant input features for a given task
Feature selectivity in the model improved classification accuracy by focusing only on the most discriminative attributes.
A seletividade de características no modelo melhorou a precisão da classificação ao focar apenas nos atributos mais discriminativos.
3. The selective attention to particular sensory attributes over others in neural processing
Olfactory neurons demonstrate feature selectivity for specific molecular structures.
Os neurônios olfativos demonstram seletividade de características para estruturas moleculares específicas.
Feature selectivity is a technical term primarily used in neuroscience, cognitive psychology, and artificial intelligence research. It is equally used in both Brazilian and American scientific communities. The term reflects the understanding that neural systems and intelligent algorithms don't process all information equally but rather focus resources on task-relevant features. This concept is fundamental to understanding how both biological brains and artificial neural networks efficiently process complex sensory information.
