| Abstract(in English) | In pattern recognition based on density estimation, it is important to estimate the likelihood at unlabeled samples under the assumption that the underlying distribution is normal. The most frequently used method is the plug-in method, where the mean and variance of normal distribution is estimated from training samples. The plug-in method is simple and can indirectly estimate the likelihood, but the accuracy is poor. We propose to estimate the likelihood directly by minimizing the squared error and show that the accuracy is substantially improved. |
