A Cognitive Model of Episodic Memory Integrated with a General Cognitive Architecture

Andrew Nuxoll, John E. Laird
2004 International Conference on Cognitive Modelling  
In this paper, we present a framework for describing the functional stages for computational models of episodic memory: encoding, storage, retrieval and use of the retrieved memories.  ...  Episodic memory provides a mechanism for accessing past experiences and has been relatively ignored in computational models of cognition.  ...  Vere Basic Agent maintained a limited episodic memory of events. However, the memory did not address issues of how to search and retrieve episodes effectively and efficiently.  ...

Optimisations have also been made for the D3PD format. We present a full evaluation of the resulting performance improvements from these, including in the case of selected retrieval of events.  ...  We detail recent changes to ROOT-based I/O within the ATLAS experiment. The ATLAS persistent event data model continues to make considerable use of a ROOT I/O backend through POOL persistency.  ...  All events are accessed with a TTreeCache of 30MB.  ...

Multimedia Indexing, Search, and Retrieval in Large Databases of Social Networks [chapter]

Theodoros Semertzidis, Dimitrios Rafailidis, Eleftherios Tiakas, Michael G. Strintzis, Petros Daras
2012 Computer Communications and Networks  
In the first part pure multimedia content retrieval issues are presented, while in the second part, the social aspects and new, interesting views on multimedia retrieval in the large social media databases  ...  Moreover, the diversity of the available content, inspired users to demand and formulate more complicated queries.  ...  Note that the comparison with M-Tree is omitted, since M-Tree belongs to the family of exact similarity search and its retrieval accuracy is always equal to 100%.  ...

William H. Batchelder, David M. Riefer
1999 Psychonomic Bulletin & Review  
In the conclusion, we consider the current role of MPT models in psychological research and possible future directions.  ...  We review a current and popular class of cognitive models called multinomial processing tree (MPT) models.  ...  in which storage and retrieval both increase with age but with stronger changes for storage (e.g., Brainerd et aI., 1990, Experiment 2; Howe, 1995) .  ...

Episodic Memory in a Cognitive Model

David Ménager
2016 International Conference on Case-Based Reasoning  
Then we discuss three architectural implications of the new capability and list some future work before we conclude.  ...  The ability to remember events plays an important role in human life. People can replay past events in their heads and often make decisions based on the retrieved information.  ...  This hierarchy, illustrated in Figure 1 , provides an interesting indexing scheme for the retrieval and storage of episodes.  ...

A retrieval technique for high-dimensional data and partially specified queries

Ratko Orlandic, Byunggu Yu
2002 Data & Knowledge Engineering  
This indexing mechanism is a general-purpose point access method that effectively attacks the limitations of KDB-trees in spaces with many dimensions, while preserving the simplicity and relatively good  ...  The analytical and experimental results show that the new indexing scheme outperforms two other variants of KDB-trees investigated in the paper for both fully and partially specified queries. Ó  ...  As we expected, for very small x, there is a rather severe tradeoff between the storage and retrieval performance of KDB TV -trees.  ...

Clustering of search results using temporal attributes

Omar Alonso, Michael Gertz
2006 Proceedings of the 29th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '06  
Clustering of search results is an important feature in many of today's information retrieval applications.  ...  The notion of hit list clustering appears in Web search engines and enterprise search engines as a mechanism that allows users to further explore the coverage of a query.  ...  For indexing and storage, we use Oracle Text because of the combination of text and XML searching.  ...

A multinomial modeling analysis of the mnemonic benefits of bizarre imagery

David M. Riefer, Jeffrey N. Rouder
1992 Memory & Cognition  
To determine ifthese differences were due to the storage or retrieval of the items, a multinomial model for the analysis of imagery mediation in paired-aseociate learning was developed and applied to the  ...  The model revealed that bizarre sentences benefited the retrieval of the noun pairs but not their storage within memory.  ...  Figure I presents the tree diagram for the current model, and from this tree structure it is easy to write expressions for the probabilities of each data event: P(E I ) = arlr20 (1a) P(E 2 ) = a(1-rl)  ...

Close pair queries in moving object databases

Panfeng Zhou, Donghui Zhang, Betty Salzberg, Gene Cooperman, George Kollios
2005 Proceedings of the 2005 international workshop on Geographic information systems - GIS '05  
The retrieval component takes advantage of a new index mechanism, the Multiple TSB-tree. The segments are then pipelined to the close-pair identification component.  ...  This paper solves the range close-pair query using two components: the retrieval component and the close-pair identification component.  ...  The range close-pair query is important in real-life applications, but it has not been studied before. We propose a storage scheme (Multiple TSB-tree) and a retrieval method based on the MTSB-tree.  ...
