Abstract: There are provided a method, an apparatus, a device, and a storage medium for model training. In a method, a target model is fine-tuned using a set of training data, each training data including a sample question and corresponding annotation information, the annotation information including policy information for solving the sample question and answer information of the sample question. At least one sample question in the set of training data is provided to the fine-tuned target model to determine a candidate answer to the at least one sample question. The fine-tuned target model is trained based at least on a comparison between the candidate answer and the answer information of the at least one sample question.

Abstract: Implementations of the present disclosure provide a method, a device, and an apparatus for verifying a veracity of a statement, and a medium. In One method, includes: training data including a statement, an evidence set, and a label are acquired. The statement is divided into a plurality of phrases based on a grammatical analysis of the statement. A phrase verification model is trained based on the training data and the plurality of phrases, so that the phrase verification model determines a plurality of phrase veracities of the plurality of phrases respectively based on the evidence set. A statement verification model is trained based on the training data and the plurality of phrases, so that the statement verification model determines a statement veracity of the statement based on the evidence set, where the plurality of phrase veracities provide an interpretation for the statement veracity.

Abstract: A keyboard with adjustable key rows comprises a plurality of keys arranged as left-hand and right-hand parallel key rows, including three left-hand alphabetic key rows and three right-hand alphabetic key rows. At least two said key rows are adjustable key rows that are mounted on individual sliding bases and can be shifted in their supporting slots for continuously adjusting the key row positions for typing operation. Locking means, adjusting means and linking means are presented for facilitating the adjustments of said adjustable key rows. The operator of said keyboard can reorganize the key arrangement of said keyboard flexibly and ergonomically according to the operator's typing preferences to increase comfort and typing speed.
