Part of our vision for this journal is to underline the importance of ensuring a flexible and open-ended definition of big data, one that can change with time, in order to meet the increasingly wide expectations of our multi-disciplinary audience. We believe such flexibility is important, as the past is an indicator of the future and the size and scale of problems is only expected to increase.
Analytics will play an increasingly central role in making sense of big data and exploiting its value, drawing on powerful human cognitive capabilities such as learning, pattern recognition and classification in real-world noisy and imprecise environments. This will, in turn, aid the mining of heterogeneous data sets for revealing hidden knowledge, patterns, and relationships. The human brain’s neocortex for instance, has been described as the world’s most advanced, associative, and predictive big data engine [2].
However, learning from big data will also require the development of novel types of algorithms and architectures. Most conventional machine-learning algorithms cannot easily scale up to big data, hence cannot cope with the associated challenges of high dimensionality, velocity, and variety. Next-generation, scalable, cognitive, and neural technologies are expected to become significant components of big data analytics platforms, and our pioneering open access journal aims to advance this collaboration. In the long term, we hope this journal will promote new advances and cross-disciplinary research directions in the development of a range of efficient and innovative algorithmic, theoretical, experimental, computational and integrative approaches to analyse big data, facilitating solutions for diverse complex real-world problems.
