Parallax: Visualizing and Understanding the Semantics of Embedding Spaces via Algebraic Formulae
Table 1: Two-way ANOVA analyses of Task (Commonality vs. Polarization) and Obfuscation (Obfuscated vs. Non-obfuscated) over Projection (Explicit Formulae vs. t-SNE).

that the proposed Explicit Formulae method outperforms t-SNE in terms of accuracy in both Commonality and Polarization tasks. We also observed significant differences in Obfuscation: subjects tend to have better accuracy when the words are not obfuscated. We run post-hoc t-tests that confirmed how the accuracy of Explicit Formulae on Non-obfuscated is significantly better than Obfuscated, which in turn is significantly better that t-SNE Non-obfuscated, which is significantly better than t-SNE Obfuscated. Concerning Preference, nine out of all twelve (75%) subjects chose Explicit Formulae over t-SNE. In conclusion, our answers to the research questions are that (Q1) Explicit Formulae leads to better accuracy in goal-oriented tasks, (Q2) users prefer Explicit Formulae over t-SNE.
