LCCM consists of two sub-models, a class membership model that formulates the probability of an individual belonging to a specific segment/class and a class-specific choice model that estimates the choice proba
Online Latent Dirichlet Allocation (LDA) in Python, using all CPU cores to parallelize and speed up model training.The parallelization uses multiprocessing; in case this doesn’t work for you for some reason, try the gensim.models.ldamodel.LdaModel class which is an equivalent, but more straigh...
We first demonstrate that CEBRA significantly outperformst-SNE, UMAP, automatic LFADS (autoLFADS)25and pi-VAE (the latter was shown to outperform PCA, LFADS, demixed PCA and PfLDS (Poisson feed-forward neural network linear dynamical system) on some tasks) in the reconstruction of ground trut...

The generation of synthetic data can be used for anonymization, regularization, oversampling, semi-supervised learning, self-supervised learning, and several other tasks. Such broad potential motivated the development of new algorithms, specialized in da
It may occur that the group structure is known and does not need to be estimated. In such instances,grouped_plm()andgrouped_tv_plm()make it easy to estimate a (time-varying) linear panel data model given an observed grouping. groups<-sim$groupsestim_oracle<-grouped_plm(y~.,data=data,...
models, while the LMR was significant only for the one to three-class models. As the number of classes increased, the AIC, BIC, and aBIC values progressively decreased, and the scree plot of aBIC flattened after the three-class model (Fig.1), suggesting a point of diminishing returns. ...

Nevertheless, alternative same expressions without explicit use of these categories might be present in the lin- guistic construction of the second group, though hard to be noticed by the models. For instance, in the piece of text I know what the class of the galaxy, when I look at the ...
