Correlation Matrix Memory

is learned, it is stored in the brain, from e recalled later when required. Memory G y be d i v i d m t e r m ’ ” x m o r y , depending on the retention time (Arbib, 1989). Short-term memory refers to a compilation of knowledge representing the “current” state of the environment. Any discrepancies between knowledge stored in short-term memory and a “new” state are used to update the short-term ...

On the Entropy Based Associative Memory Model with Higher-Order Correlations

In this paper, an entropy based associative memory model will be proposed and applied to memory retrievals with an orthogonal learning model so as to compare with the conventional model based on the quadratic Lyapunov functional to be minimized during the retrieval process. In the present approach, the updating dynamics will be constructed on the basis of the entropy minimization strategy which...

Enhanced Boolean Correlation Matrix Memory

of the Correlation Matrix Memory (CMM), which is useful to work with binary memories. A novel Boolean Orthonormalization Process (BOP) is presented to convert a non-orthonormal Boolean basis, i.e., a set of non-orthonormal binary vectors (in a Boolean sense) to an orthonormal Boolean basis, i.e., a set of orthonormal binary vectors (in a Boolean sense). This work shows that it is possible to im...

Higher-Order Risk Attitudes toward Correlation

Higher-order risk attitudes other than risk aversion (e.g., prudence and temperance) play vital roles both in theoretical and empirical work. While the literature has mainly focused on how they entail a preference for combining “good” outcomes with “bad” outcomes, We consider here an alternative approach which relates higher-order risk attitudes to the sign of correlation. The theoretical resul...
