Shiffrin & Steyvers' (1997) REM adapted to cross-situational word
learning. Word/object identity is a length-w feature vector drawn from a
geometric base-rate distribution (g); each trial stores one episodic
trace per candidate word-object pairing present, built by imperfectly
copying the pair's true features (each feature independently stored with
probability u, and if stored, correct with probability c, else a fresh
random draw). At test, a candidate pairing's strength is the summed
likelihood ratio of every trace given the true (fully-known) probe
features, REM's odds-based alternative to minerva2()'s dot-product
activation.
Arguments
- g
Base-rate feature-value distribution parameter (larger = more variable/distinctive feature values, in (0, 1))
- u
Per-feature storage probability at study, in (0, 1)
- c
Probability a stored feature is copied correctly (vs. replaced by a random, possibly-confusable value), in (0, 1)
- w
Number of features per item (fixed hyperparameter, not a free cognitive parameter)
Details
Performance note: unlike minerva2() (one trace per trial) this model
stores one trace per candidate (word, object) pair per trial – on a
highly ambiguous corpus (many words/objects per utterance) memory size
grows combinatorially rather than linearly with trial count, and both
encoding and the voc_sz * ref_sz test pass scale with that trace count,
making rem() the most expensive of this package's memory models on
cluttered/naturalistic data. w is a fixed representational
hyperparameter (not usually treated as a free cognitive parameter), not
included by default in this package's DEoptim registry bounds – see
xsl_model_registry().
Examples
mod <- rem(g = 0.4, u = 0.3, c = 0.7, w = 12)
