title: A study of Tibetan text classification based on CBAt hybrid neural network model
title: 基于CBAt混合神经网络模型的藏文文本分类研究

description: Text classification is an important research work in the field of natural language processing, and the emergence of deep learning methods has greatly promoted the development of text classification techniques, which is also effective for Tibetan text classification. This paper proposes a CBAt hybrid neural network based Tibetan text classification model to classify 14,000 texts in Tibetan dataset, using the convolutional results in the traditional CNN model as the input of the BiLSTM model and introducing the Attention mechanism to increase the model's feature extraction of important information of Tibetan texts, so as to improve the classification accuracy. The paper also compares this dataset with traditional machine learning algorithms and a single neural network model, and the experimental results show that the improved hybrid neural network model proposed in this paper performs better in the classification of Tibetan texts.

title: Korean Grapheme-to-phoneme Conversion Algorithm Based on Decision Tree
title: 基于决策树的朝鲜语字音转换方法研究

description: In the resource construction of Korean speech information processing, grapheme-to-phoneme conversion technology plays a vital role. According to the Korean pronunciation rules and the law of word boundaries phonetic variation, this paper defines the attributes used to construct the decision tree, and realizes the Korean phonetic conversion algorithm based on the CART decision tree, so that the phonetic representation can reflect the phonetic changes such as syllable weakening, falling off, increasing and alienation in the continuous speech stream, and accurately obtain the phonemes corresponding to the graphemes. By the cross-validation, the average conversion accuracy can reach to 94.63%.

title: Statistical analysis of The type of Syllable error in Tibetan text
title: 藏文文本语料中音节错误类型的统计分析

description: Tibetan information processing is greatly influenced by the quality of Tibetan texts. It is an effective way to improve the quality of Tibetan texts to correct the complex and diverse syllable errors. This paper uses real Tibetan text as statistical source, which contains more than 150 million syllables. 2333617 wrong syllables were found by computer, accounting for 5.6% of the total corpus texts. According to the context information and Tibetan grammar rules, error syllables were manually corrected and classified into 11 types, and the occurrence frequency and high frequency error syllables of each type were counted. By analyzing the error causes, it provides some references for the design and implementation of Tibetan text proofreading system and other software.

title: 面向自然语言理解的神经编解码

description: In recent years, distributed representation and codec technologies have been widely used in natural language processing. At the same time, they have also provided new approaches and paradigms for language cognitive computing research. So, how does the human brain represent language? How are the neural encoding and decoding performanced in different distributed representation methods? Can language information be reconstructed from neuroimaging data? This report will introduce part of the exploratory work that our team has carried out in recent years on those issues, and give preliminary prospects for the future development of this direction.

title: In vitro long-term culture of cynomolgus monkey embryos to early neurulation stage（maca_DNA_rawdata）
title: In vitro long-term culture of cynomolgus monkey embryos to early neurulation stage（maca_DNA_rawdata）

description: Neurulation is the process of forming the neural tube. The complex characteristics of primate neurulation remain mysterious due to the limited accessibility of primate embryos at this stage. Here, we established a 3D prolonged in vitroculture (pIVC) system to support the cynomolgus monkey blastocyst developing to E25 to early neurulation. The pIVC E25 embryos highly recapitulated the critical events of their in vivo counterparts during early neurulation, which include the specialization of the neural plate, closure of the neural tube, regionalization of neural tube cells, specialization and migration of neural crest cells and differentiation of motor neurons and sensory placodes. Single-cell multi-omics analysis of the pIVC embryos further verified the specification of early neural cells, suggesting the pIVC embryos developing to a more advanced stage. Besides, the DNA methylation and chromosome accessibility of three germ layers were in-deep analyzed. This study will help to explore the characteristics and underlying mechanisms of primate neurogenesis, which will be of fundamental and clinical importance.

title: Preliminary considerations about large models
title: 关于大模型的初步考量

description: In recent years, the large-scale pre-training language models, represented and originated by BERT and GPT3, have "unexpectedly" become the strategic focus and hotspot of technology competition in the entire artificial intelligence field and leading trends for a period (such as the springing up endlessly Pre-training language models as well as pre-training multi-modal models). NLP based on deep learning is advancing all the way along the track of "extremely large data, large models, and large computing power". This trend has produced a number of surprising but also somehow puzzling phenomena. For example,how should we regard the large model? What related research should be conducted? This report will present some preliminary considerations and discussions on those issues.

title: Raw Data for the article "Development of novel C2-symmetrical [5]oxahelicenoid diols"

description: we synthesized a new C2-symmetric [5]oxahelicenoid diol 14 from [5]oxahelicenoid dione 13 by either DDQ mediated or Pd/C catalyzed dehydrogenative aromatization. Optical resolution of (rac)-14 with N-benzylquininium chloride 15 and N-benzylquinidinium chloride 16 afforded the enantiomerically pure (P)-14 and (M)-14, respectively. In addition, six chiral phosphoric acids 19a~19f were synthesized from (P)-14 and subjected to an enantioselective Friedel-Crafts reaction to afford the desired product 22 in good results (up to 94% yield, 76:24 er). The result indicates that the catalysts based on our newly synthesized [5]oxahelicenoid diol have comparable catalytic activity as BINOL-based and SPINOL-based ones.
