(overparameterize)
too many parameters
Etymology
'overparameterized' is formed in modern English by the prefix 'over-' + the verb 'parameterize' (from 'parameter' + the verb-forming suffix '-ize').
'parameter' originates from Greek 'para' (beside) + 'metron' (measure) via Latin/Modern scientific usage; 'parameterize' is a modern English formation meaning 'to express in terms of parameters', and 'overparameterize' (and its adjective/past-participle 'overparameterized') arose in technical usage in the 20th century, especially in statistics and computing.
Originally 'parameter' referred to a limiting or defining measure; 'parameterize' came to mean 'to describe or model using parameters', and 'overparameterized' now specifically conveys 'modeled with more parameters than appropriate (often causing overfitting)'.
