Like as Data Mining, Web Mining has four stages i.e. Data Collection, Preprocessing, Knowledge Discovery and Knowledge Analysis. This paper based on the first two stages Data collection and ...

We have implemented six of the most popular data preprocessing algorithms, three for discretization and the rest for feature selection. The algorithms have been tested using two Big Data datasets.

including with the categorical data. Fun fact / background: some stranger in Upwork (freelancing) requested a python implementation of this algorithm. The task hooked my curiosity and I wanted to ...

Then, the improved crow search algorithm is used to find the optimal solution for the data filling model. Finally, the filling model optimized by the algorithm is used to construct a heterogeneous ...

Kim and his colleagues developed an offline algorithm that estimates min-entropy based on a whole data set, and an online estimator that only needs limited data samples. The accuracy of the online ...

To fill this gap, we propose a combined prediction system based on fuzzy granulation, multi-objective dragonfly optimization algorithm ... data pretreatment method to eliminate the negative influence ...
