**Explanation:**
- Precompute `sum(features) % self.num_classes` once instead of computing `sum(features)` and `% self.num_classes` for each element in the list comprehension.
- Use list multiplication (`[total_mod] * features_len`) which is much faster than list comprehension for repeating the same value.
