Ndaona is a Matlab toolkit to create in- teractive three-dimensional models of data often found in NLP research, such as ex- ploring the results of classification and di- mensionality reduction algorithms. Such models are useful for teaching, presen- tations and exploratory research (such as showing where a classification algorithm makes mistakes). Ndaona includes embedding and graph- ics parameter estimation algorithms, and generates files in the format of Partiview (Levy, 2001), an existing free open-source fast multidimensional data displayer that has traditionally been used in the plane- tarium community. Partiview1 supports a number of enhancements to regular scat- terplots that allow it to display more than three dimensions’ worth of information. 1 Supplemented Scatterplots Scatter...
