  • Pre-Processing in Natural Language Machine Learning

    Nov 28, 2017 · It is easy to forget how much data is stored in the conversations we have every day. With the evolution of the digital landscape, tapping into text, or Natural Language Processing (NLP), is a growing field in artificial intelligence and machine learning. This article covers the common pre-processing concepts applied to NLP problems.

  • Preprocessing and Image Enhancement Algorithms for a .

    Good preprocessing techniques preceding the classi-fication process can greatly enhance recognition accuracy [15, 12]. In what follows, in Section 2, we discuss in some detail a robust and efficient algorithm for form image registration. Thereafter in Sections 3, 4 and 5, three techniques for image masking and image improvement are discussed
