Similarity evaluation on θ. Comparison between estimated θ ∗ and true mixture proportions θ for the first six profiles. Top: radar charts with 10 spokes, each representing a source in topic panel. The proportion of each source is depicted by the length of lines with color (orange for estimation θ ∗ and blue for ground truth θ). Bottom: scatter plots of corresponding proportions in ground truth θ and estimation θ ∗. The correlation coefficients ρ are given on the left-top
