Statistical Data Analysis with Julia
About the training
The ability to use methods based on principal component analysis enables to perceive data in a new and unique way. By conducting this process by yourself you will be able to enter a multidimensional world. This method enabled physicists to discover and understand the world of quantum mechanics in 20th century; it’s also a basis for the developing big data branch.
The reduction of data and discovering hidden relationships between a big number of variables are the key problems of big data. Julia Environment gives an access to highly efficient libraries which make the processing of huge matrix possible. The training is aimed at expanding knowledge by conducting and presenting the whole process as well as understanding and interpreting the results.
