log-likelihood
Technical term in statistics and machine learning; the natural logarithm of the likelihood function, often used for optimization.
In maximum likelihood estimation, we find the parameters that maximize the log-likelihood.
The log-likelihood of this model was -120.5.
尤度 is the likelihood itself; 対数尤度 is its logarithm, used for computational convenience.
最尤推定 is the estimation method that maximizes the likelihood (or log-likelihood).
Compound of 対数 (logarithm) and 尤度 (likelihood), a direct translation of the English term 'log-likelihood'.
