Applying Automatic Differentiation and Truncated Newton Methods to Conditional Random Fields

碩士 === 國立臺灣大學 === 資訊工程學研究所 === 96 === In recent years, labeling sequential data arises in many fields. Conditional random fields are a popular model for solving this type of problems. Its Hessian matrix in a closed form is not easy to derive. This difficulty causes that optimization methods using se...
