Recognition of teaching method effects based on grid model simplification and artificial intelligence

In order to improve the effect of the teaching method evaluation model, based on the grid model, this paper constructs an artificial intelligence model based on the grid model. Moreover, this paper proposes a hexahedral grid structure simplification method based on weighted sorting, which comprehensively sorts the elimination order of candidate base complexes in the grid with three sets of sorting items of width, deformation and price improvement. At the same time, for the elimination order of basic complex strings, this paper also proposes a corresponding priority sorting algorithm. In addition, this paper proposes a smoothing regularization method based on the local parameterization method of the improved SLIM algorithm, which uses the regularized unit as the reference unit in the local mapping in the SLIM algorithm. Furthermore, this paper proposes an adaptive refinement method that maintains the uniformity of the grid and reduces the surface error, which can better slow down the occurrence of geometric constraints caused by insufficient number of elements in the process of grid simplification. Finally, this paper designs experiments to study the performance of the model. The research results show that the model constructed in this paper is effective.

Some Diachronic Phonological changes from Proto-Kuki-Chin to Lutuv

Lutuv (Lautu) is a Kuki-Chin language that VanBik (2009) places in the Maraic branch alongside Zophei, Mara, Senthang, and Zotung. Lutuv is of particular interest to the diachronic development of Maraic languages in that it is geographically central in the Maraic-speaking area, but shows some differences in historical development from its neighbors. This project is based on my dissertation research on Zophei and was first presented to Dr. Kelly Berkson’s Field Methods class on Lutuv in order to offer researchers of Lutuv (like those in the field methods class) a finer grained look at the diachronic development of syllable rhymes in Lutuv, specifically in comparison with the most closely related Kuki-Chin languages Zophei and Mara. The data set this paper is published separately in this volume as Lexical correspondences between Proto-Kuki-Chin, Hakha Lai, and six Maraic varieties(Lotven, 2020). This research is presented here to be of use to other Lutuv researchers, researchers of Kuki-Chin more broadly, and historical phonologists interested in rhyme development and syllable structure simplification.

PENYEDERHANAAN FONOLOGIS DALAM PEMEROLEHAN BAHASA PERTAMA: STUDI KASUS ANAK USIA 1;9

This research was conducted to determine the utterances that can be produced by a child and the simplification process that occurs in the utterances produced. The subject of this study is female twins aged 1 year 9 months. This study uses the method of observation, the researcher observes the two children, records and takes note the words spoken. The researcher participates in communicating with these children. Furthermore, the data that has been obtained in the form of records is transcribed into written form. The list of writings that have been obtained is then identified to find out the simplification process that occurs by comparing with the utterances that should be according to the dictionary and simplification theory in language acquisition. Data that has been analysed are then presented in tabular form and also presented with sentences. The results showed that there were several simplification processes for the utterances produced in the form of substance, reduction and word structure simplification. These two children are able to produce /m/, /k/. /t/, /d/, /p/, /n/, /b/, /a/, /o/,/i/, /ɑː/, /e/.

The syllable in Kuki-Chin

The Kuki-Chin group of the Tibeto-Burman language family consists of upwards of 50 languages spoken mainly in western Myanmar, predominantly in Chin State and in neighboring areas of India and Bangladesh (Simons & Fennig (eds.). 2019. Ethnologue: Languages of the world, 21st edn. Dallas Texas: SIL International. Online version. http://www.ethnologue.com/). In the many daughter languages of Proto–Kuki-Chin, syllable structure simplification has yielded a synchronic situation in which individual languages are spread along a cline ranging from more conservative languages, some with complex onsets and vowel length distinctions, to more innovative languages, some with no coda consonants at all. The distribution and phonetic realization of these features vary across the Kuki-Chin group, raising a number of relevant questions about the underlying phonological representations of the Kuki-Chin syllable. This paper surveys representative structures from a variety of Kuki-Chin languages in order to highlight issues in syllable structure across these little-studied languages. In doing so, we aim to both unify observations on Kuki-Chin phonology related to the syllable, and to propose research that will further elucidate its structures.
