1. In signal processing and statistics, a threshold value where data points are definitively classified as either above or below the threshold with no intermediate values allowed
The hard threshold method discards all coefficients below a certain value, setting them exactly to zero.
O método de limiar duro descarta todos os coeficientes abaixo de um determinado valor, definindo-os exatamente como zero.
2. A fixed cutoff point in data analysis or machine learning where a strict binary decision is made
Using a hard threshold for classification can lead to sharp decision boundaries.
Usar um limiar duro para classificação pode levar a limites de decisão acentuados.
