Proactive interferencebuilds up with exposure to multiple lists of similar items with a resulting reduction in recall. This study examined the effectiveness of using a proactive strategy of the method of loci to reduce proactive interference in a list recall paradigm of categorically similar words. While all participants reported using some form of strategy to recall list words, this study demo...

The performance of a Content-Based Image Retrieval (CBIR) system presented in the form of Precision-Recall or PrecisionScope graphs offers an incomplete overview of the system under study: the influence of the irrelevant items is obscured. In this paper, we propose a comprehensive and well normalized description of the ranking performance compared to the performance of an Ideal Retrieval System...

We present an exact equilibrium analysis of a class of associative memory models with spatial structure in the form of combined shortand long-range synapses. We solve the models for sequential and parallel dynamics by use of random-field techniques and we find that competing interactions induce continuous and discontinuous bifurcations of the overlap order parameter as well as coexistence of di...

The Xapagy architecture is a story-oriented cognitive system which relies exclusively on the autobiographical memory implemented as a raw collection of events. Reasoning is performed by shadowing current events with events from the autobiography. The shadows are then extrapolated into headless shadows (HLSs). In a story following mood, HLSs can be used to track the level of surprise of the agen...

Recall what we are shooting for: a multi-parameter analog of Myerson’s theory of revenuemaximizing optimal auctions. Single-parameter optimal mechanisms are virtual welfare maximizers. We’ve seen that multi-parameter optimal mechanisms are generally randomized. It would seem that the coolest statement that could be true is: revenue-maximizing optimal auctions for multi-parameter problems are al...

Four verbal implicit memory tests, word identification, word stem completion, word fragment completion, and anagram solution, were directly compared in one experiment and were contrasted with free recall. On all implicit tests, priming was greatest from prior visual presentation of words, less (but significant) from auditory presentation, and least from pictorial presentations. Typefont did not...

We present a simple primal-dual algorithm for computing approximate Nash equilibria in two-person zero-sum sequential games with incomplete information and perfect recall (like Texas Hold’em poker). Our algorithm only performs basic iterations (i.e matvec multiplications, clipping, etc., and no calls to external first-order oracles, no matrix inversions, etc.) and is applicable to a broad class...

Journalists are increasingly turning to technology for pre-filtering and automation of the simpler parts of the verification process. We present results from our semi-automated approach to trust and credibility analysis of tweets referencing suspicious images and videos. We use natural language processing to extract evidence from tweets in the form of fake & genuine claims attributed to trusted...
