Topological Data Analysis (TDA) is an emerging and highly successful approach to Big Data problems. The underlying idea is to employ topological techniques in the analysis of large quantities of data. One of the main difficulties with real-world data is that its collection introduces various types of 'noise'. Distinguishing between true features, inherent to the phenomenon in question, and misleading features resulting from noise contamination can be very challenging. Topology, by design, is blind to matters of scale or dimensionality. Its tools are aiming to extract geometric features which are robust in comparison to scale or dimensionality distortions. TDA seeks to exploit the inherent noise-blindness of topology by employing topological techniques to data analysis.
TDA represents a unique intersection point of pure mathematics with applied mathematics. In recent work such a formalism for topology was identified and is being developed. The advantages of the formalism to the foundations of topology are demonstrated while more advanced features are being tested. Alongside the topological gains, applications to the foundations of TDA are emerging as well. The main aims of the project are: 1) further enhance and develop the new mathematical foundations of topology; and 2) investigate the flow of ideas between topology and TDA along this new bridge, with new applications of TDA in mind.
The project aims to investigate alternative formalisms of topology with the aim of facilitating a smoother transition of topological tools to TDA, thereby enlarging the scope of applicability of TDA, while at the same time adjusting the classical topological methodologies to allow insights from TDA to filter back to topology. Using this improved language and tools new algorithms will be developed and tested for tackling TDA problems.
