+# Solution sketches to various texts
+
+----
+
+Here are some solutions to selected problems from several foundational texts in a variety of fields. These mostly represent my own progress through teaching myself a more rigorous foundation of the mathematics underpinning modern statistics and ML. I can only hope that they also provide valuable insights for others on this journey.
