Figure 4
A scatter plot of document embeddings by AI vs non-AI label. The plot features hundreds of data points, with blue dots representing AI and orange dots representing non-AI. The x-axis and y-axis are labeled as Dim 1 and Dim 2, respectively. The data points are scattered with no clear trend, showing clusters of both AI and non-AI labels throughout the plot. The legend in the top right corner indicates the color coding for AI and non-AI labels. All values are approximated.t-SNE scatter plot of document embeddings by AI vs non-AI label
