结构方程模型(Structural Equation Modeling,SEM)是一种建立、估计和检验因果关系模型的方法。模型中既包含有可观测的显在变量,也可能包含无法直接观测的潜在变量。结构方程模型可以替代多重回归、通径分析、因子分析、协方差分析等方法,清晰分析单项指标对总体的作用和

semopy is a Python package for Structural Equation Modelling (SEM) with latent variables. It is open-source, distributed free of charge, simple and fast to use and has plenty of features to aid a researcher.
Hi, I already talked with Ólavur about this and would like to suggest adding Structural Topic Models to gensim. STM's are basically (besides other things) a generalization of author topic models, where topic proportions are affected by c...
Thus we developed the Python package $extbf{semopy}$ to satisfy those criteria. The paper provides detailed examples of package usage and explains it's inner clockworks. Moreover, we developed the unique generator of SEM models to extensively test SEM packages and demonstrated that $extbf{...

(TFIDF) matrix for all PDB and AF proteins, in which the terms are shape-mers and each protein is equivalent to a document. We performed topic modeling using NMF, which attempts to factorize a matrix of sizen×minto matricesWof sizen×p, andHof sizep×m. We interpret this as findingp...
To this end, we perform topic modeling using BERTopic (BERT for Topic Modelling) [20]. BERTopic is a topic modelling technique that uses transformers and the c-TF-IDF to produce dense clusters that allow for clearly understandable topics while maintaining key phrases in the topic descriptions....
GemPy is an open-source, Python-based 3-D structural geological modeling software, which allows the implicit (i.e. automatic) creation of complex geological models from interface and orientation data. It also offers support for stochastic modeling to add
