- the experiment only measured the ability to dicriminate previosly seen |
1099 |
|
textures from unseen textures. However, our experience shows that |
1100 |
|
at least the most recurring textures can easily be associated to the |

document content. |

- as per Zipf's law [XXXref], it suffices to learn the textures |

of the most recurring documents. |
