Phonetic Transcription

/pəˈdrɪkʃən (prɪˈdɪktɪv) ˈɛrər/

Meaning and Usage

Prediction error refers to the difference between what was predicted and what actually occurred. It is commonly used in various fields such as psychology, statistics, machine learning, and neuroscience to evaluate the accuracy of forecasts or models.

Predictive error generally relates to a specific type of prediction error related to forecasts made by predictive models.

Both terms are frequently used in academic writing and technical contexts rather than everyday conversation, although they can appear in spoken discussions in specialized fields.

Example Sentences

1. In machine learning, a low prediction error indicates that the model is performing well.

2. En aprendizaje automático, un bajo error de predicción indica que el modelo está funcionando bien.

3. The predictive error of the new algorithm was significantly lower than the previous versions.

4. El error predictivo del nuevo algoritmo fue significativamente menor que las versiones anteriores.

5. Understanding the sources of prediction error can help refine future models.

6. Comprender las fuentes del error de predicción puede ayudar a mejorar los modelos futuros.

Idiomatic Expressions

While "prediction" and "error" may not be part of traditional idiomatic expressions, they play a crucial role in technical jargon and can be combined with other terms to create meaningful phrases. Here are some examples:

1. "To lower the prediction error, data scientists often use ensemble methods."

2. Para reducir el error de predicción, los científicos de datos a menudo utilizan métodos de ensamblaje.

3. "The model's predictive power needs to be validated to assess its predictive error."

4. La capacidad predictiva del modelo necesita ser validada para evaluar su error predictivo.

5. "After identifying the sources of predictive error, researchers adjusted their methodology."

6. Después de identificar las fuentes del error predictivo, los investigadores ajustaron su metodología.

7. "She explained that prediction error could be minimized through better data collection processes."

8. Ella explicó que el error de predicción podría minimizarse mediante mejores procesos de recolección de datos.

Etymology

The word "prediction" comes from the Latin root praedicere, which means "to foretell" (from prae- "before" and dicere "to say"). The adjective "predictive" is formed from predict with the suffix -ive, indicating a tendency to perform a function.

The term "error" derives from the Latin errorem, meaning "a wandering, straying," which signifies a deviation from accuracy or correctness.
