# keyed_representation

A localist representation where each dimension represents a distinct object or feature. Typically comes from string columns in dataframes, or created by a conversion as its target automatically, rather than configued manually. Its natural pattern is a localist_pattern, but it is very helpful when used with strength_pattern-based layers.

# add_symbol

    some_kr add_symbol sym

Explicitly extend the representation `some_kr` to have the additional dimension `sym`.

# conversion_key

    some_kr conversion_key

Return a key_conversion that converts to a dimension name from the corresponding unit (basis) vector.

# conversion_unkey

    some_kr conversion_unkey

Return a unkey_conversion that converts from a dimension name to a corresponding unit (basis) vector.
