### `///` admonitions

1) Keep the admonition keyword in English (do not translate `note`, `tip`, etc.).
2) Many Traditional Chinese docs currently omit titles in `///` blocks; that is OK.
3) If a generic title is present, prefer these canonical titles:

- `/// note | 注意`

Notes:

 *       rate when using completely <i>random</i> sample input. The true test of a hash function is
 *       how it performs on representative real-world data, which tends to contain many hidden
 *       patterns and clumps. The goal of a good hash function is to stamp these patterns out as
 *       thoroughly as possible.

*   Various performance improvements, especially for RNNs and convolutions
*   Many bugfixes
*   Nightly builds, tutorial tests, many test improvements
*   New examples: transfer learning and deepdream ipython notebook
*   Added tutorials, many documentation fixes.
