Multidimensional big data can also be represented as tensors , which can be more efficiently handled by tensor-based computation,  such as multilinear subspace learning .  Additional technologies being applied to big data include massively parallel-processing ( MPP ) databases, search-based applications , data mining ,  distributed file systems , distributed databases , cloud and HPC-based infrastructure (applications, storage and computing resources)  and the Internet. [ citation needed ] Although, many approaches and technologies have been developed, it still remains difficult to carry out machine learning with big data.
