Data mining is the process of discovering or extracting new patterns from large data sets involving methods from statistics and artificial intelligence. The Decision Tree is an important classification method in data mining classification. The classification algorithm of the decision tree ID3, C4.5,CART...
Using data from the American Time Use Survey (ATUS) for the years 2003 to 2019, we find that same-sex couples specialize not as much as different-sex couples. We argue that these differences are driven by the most traditional couples in the sample, that is to say, married couples with ...
Therefore, using the weighting scheme in geo-social media context could lead to issues, some of which are described hereafter. Yamasaki et al. (2015) see problems with use of tf-idf for hashtag analyses. On the one hand, because a hashtag usually appears only once per tweet, i.e. per...

The investigation compares the conventional, advanced machine, deep, and hybrid learning models to introduce an optimum computational model to assess the ground vibrations during blasting in mining projects. The long short-term memory (LSTM), artificial neural network (ANN), least square support vector...

One of the main controversial issues in this area is that different MCDM methods, even when they use the same input, produce different and potentially conflicting rankings, which means that finding an overall aggregated ranking of alternatives is of the essence. Some studies ignore the existence of...
