I used the notebook 02_fit_predict_plot_employee_salaries.html to compare the performance using SVD (with same number of components as MinHashEncoder). This could be added to the current or different notebook, if you agree.

one-hot encoding
r2 score: mean: 0.856; std: 0.034

target encoding
r2 score: mean: 0.774; std: 0.033

similarity encoding
r2 score: mean: 0.915; std: 0.012

minhash encoding
r2 score: mean: 0.753; std: 0.025

svd encoding
r2 score: mean: 0.856; std: 0.014
