We investigated the effectiveness of Digit Embedding. We can see that the numbers in the (100090-100140) range are clustered together. We investigated with more ranges. Figure 3 shows the 2-d embedding of decimal numbers in the range [1.0, 10.0] and [20.0-31.0]. And the numbers with larger differences like (1.6478, 30.7010), (5.339, 30.5113) are far from Please note that in this setup, the Digit Embedding is still applied.
