Technical Report PDP.CNS.95.2 Familiarity Breeds Differentiation: A Bayesian Approach to the Effects of Experience in Recognition Memory James L. McClelland and Mark Chappell As people become better at identifying studied items, they also become better at rejecting distractor items. A model of recognition is presented consisting of item detectors that learn estimates of conditional probabilities of items' features, exhibiting this differentiation effect. The model is used to account for a number of findings in the recognition memory literature, including a null list-strength effect, a list-length effect, non-linear effects of strengthening items on false recognition of similar distractors, a number of different kinds of mirror effects, and appropriate $z$-ROC curves.

Title: Developing Object Permanence: A Connectionist Model (6 pages) Authors: Denis Mareschal, Kim Plunkett, Paul Harris Department of Experimental Psychology South Parks Rd University of Oxford Oxford OX1 3UD UK Abstract: When tested on surprise or preferential looking tasks, young infants show an understanding that objects continue to exists even though they are no longer directly perceivable. Only later do infants show a similar level of competence when tested on retrieval tasks. Hence, a developmental lag is apparent between infants' knowledge as measured by passive response tasks, and their ability to demonstrate that knowledge in an active retrieval task. We present a connectionist model which learns to track and initiate a motor response towards objects. The model exhibits a capacity to maintain a representation of the object even when it is no longer directly perceptible, and acquires implicit tracking competence before the ability to initiate a manual response to a hidden object. A study with infants confirms the model's prediction concerning improved tracking performance at higher object velocities. It is suggested that the developmental lag is a direct consequence of the need to co-ordinate representations which themselves emerge through learning.

FTP-filename: /pub/neuroprose/brunel.dynamics.ps.Z Title: Dynamics of an attractor neural network converting temporal into spatial correlations (29 pages) Network: computation in neural systems, 5: 449 Author: Nicolas Brunel Dipartimento di Fisica Universita di Roma I La Sapienza P.le Aldo Moro 2 - 00185 Roma Italy Abstract The dynamics of a model attractor neural network, dominated by collateral feedback, composed of excitatory and inhibitory neurons described by afferent currents and spike rates, is studied analytically. The network stores stimuli learned in a temporal sequence. The statistical properties of the delay activities are investigated analytically under the approximation that no neuron is activated by more than one of the learned stimuli, and that inhibitory reaction is instantaneous. The analytic results reproduce the details of simulations of the model in which the stored memories are uncorrelated, and neurons can be shared, with low probability, by different stimuli. As such, the approximate analytic results account for delayed match to sample experiments of Miyashita in the inferotemporal cortex of monkeys. If the stimuli used in the experiment are uncorrelated, the analysis deduces the mean coding level $f$ in a stimulus (i.e. the mean fraction of neurons activated by a given stimulus) from the fraction of selective neurons which have a high correlation coefficient, of $f\sim 0.0125$. It also predicts the structure of the distribution of the correlation coefficients among neurons.

The present network includes several quasi-realistic features: neurons are represented by their afferent currents and output spike rates; excitatory and inhibitory neurons are separated; attractor spike rates as well as coding levels in arriving stimuli are low; learning takes place only between excitatory units. Synaptic dynamics is an unsupervised, analog Hebbian process, but long term memory in the absence of neural activity is maintained by a refresh mechanism which on long time scales discretizes the synaptic values, converting learning into an asynchronous stochastic process induced by the stimuli on the synaptic efficacies. This network is intended to learn a set of attractors from the statistics of freely arriving stimuli, which are represented by external synaptic inputs injected into the excitatory neurons. In the simulations different types of sequences of many thousands of stimuli are presented to the network that do not distinguish between retrieval and learning phases. Stimulus sequences differ in preassigned global statistics (including time dependent statistics); in orders of presentation of individual stimuli within a given statistics; in lengths of time intervals for each presentation and in the intervals separating one stimulus from another. We find that the network effectively learns a set of attractors representing the statistics of the stimuli, and is able to modify its attractors when the input statistics change. Moreover, as the global input statistics changes the network can also forget attractors related to stimulus classes no longer presented. Forgetting takes place only due to the arrival of new stimuli. The performance of the network and the statistics of the attractors are studied as a function of the input statistics. Most of the large scale characteristics of the learning dynamics can be captured theoretically. This model modifies a previous implementation of a LANN composed of discrete neurons, in a network of more realistic neurons. The different elements have been designed to facilitate their implementation in silicon. FTP-filename: /pub/neuroprose/brunel.spontaneous.ps.Z Title: Global spontaneous activity and local structured (learned) delay activity in cortex submitted to Journal of Neurophysiology Authors: Daniel J Amit and Nicolas Brunel Dipartimento di Fisica Universita di Roma I P.le Aldo Moro 2 -- 00185 Roma Italy Abstract: 1. We investigate the conditions under which cortical activity alone makes spontaneous activity self-reproducing and stable against fluctuations of spike rates. Invoking simple assumptions about properties of integrate-and-fire neurons it is shown that the stochastic background activity, of 1-5 spikes/second, cannot be stabilized when all neurons are excitatory. 2. On the other hand, spontaneous activity becomes self-stabilizing in presence of local inhibition: given reasonable values of the parameters of the network spontaneous activity reproduces itself and small fluctuations in the rate are suppressed. a. If the integration time constants of excitatory and inhibitory neurons at the soma are equal, {\em local} excitatory and inhibitory inputs to a neuron must balance to provide {\em local} stablility. b. If inhibition integrates faster its synaptic inputs, spontaneous activity is stable even when local recurrent excitation predominates. 3. In a network sustaining spontaneous rates of 1-5 spikes/second, we study the effect of learning in a local module, expressed in synaptic modifications in specific populations of synapses. We find: a. Initially no stimulus specific delay activity manifests itself. Instead, there is a delay activity in which, locally, {\em all} neurons selective to any of the stimuli learned have rates which gradually increase with the amplitude of synaptic potentiation. b. When the average LTP increases beyond a critical value, specific local attractors appear abruptly against the background of the global uniform spontaneous attractor. This happens with either gradual or discrete stochastic LTP. 4. The above findings predict that in the process of learning unfamiliar stimuli, there is a stage in which all neurons selective to any of the learned stimuli enhance their spontaneous activity relative to the rest. Then, abruptly, selective delay activity appear. Both facts could be observed in single unit recordings in delayed match to sample experiments. 5. Beyond this critical learning strength the local module has two types of collective activity. It either participates in the global spontaneous activity, or it maintains a stimulus selective elevated activity distribution. The particular mode of behavior depends on the stimulus: if it is unfamiliar, the activity is spontaneous; if similar to a learned stimulus, the delay activity is selective. These new attractors (delay activities) reflect the synaptic structure developed during learning. In each of them a small population of neurons have elevated rates, 20-30 spikes/second, depending on the strength of LTP. The remaining neurons of the module have their activity at spontaneous rates.

As in the past, EPIA 95 is an international conference with English as the official language. The conference covers all areas of Artificial Intelligence, including theoretical areas, foundational areas, and applications. The scientific program consists of invited lectures, tutorials, demonstrations and paper presentations. There will also be parallel workshops on Expert Systems, Fuzzy Logic and Neural Networks, and Applications of AI to Robotics and Vision Systems. Invited Speakers ~~~~~~~~~~~~~~~~ Marvin Minsky (MIT - USA) "Why Human Brains Can't Really Think" Manuela Veloso (CMU - USA) "Planning and Learning in Intelligent Agents" Luis B. Almeida (IST - Portugal) "The Connectionist Paradigm and AI" Rodney Brooks (MIT - USA) "The Evolutionist Approach - Past, Present and Future of AI" Tutorials ~~~~~~~~~ T1 - Artificial Life and Autonomous Robots (3.10.95 AM) Luc Steels Artificial Life studies the phenomenon of life the same way AI studies intelligence: by building artificial systems that show the same capabilities as living systems. For a growing group of researchers in AI, there must be strong connections between the two disciplines, because they believe that the principles of living systems are a prerequisite for those of intelligent systems. This tutorial is intended for a general AI audience with no prior background in biology, Alife, or robotics. It gives an overview of research in Alife, the behavior-oriented approach to AI, and the biological significance of this research. T2 - Virtual Reality - The AI perspective (3.10.95 PM) David Hogg The tutorial will examine the rapidly evolving field of Virtual Reality (VR) and explore the key role that AI could play in its future development. Participants will gain an understanding of the state of the art in VR hardware and systems, and an appreciation of the major areas in which it is being applied. With this background, the aim is to provoke interest and activity in the application of AI to VR through the development of: (1) automatons to populate virtual worlds alongside human participants; and (2) intelligent systems for creating virtual worlds from sensory images of the real world, in order to give the illusion of presence at a remote location. T3 - Introduction to Artificial Intelligence (in Portuguese - 3.10.95 AM) Ernesto Costa Artificial Intelligence is the enterprise of building intelligent agents. An intelligent agent is an entity that perceives, reasons about and acts upon the environment. We will start by briefly discussing the different paradigms (symbolic, connectionist, genetic, emergent) that had been proposed as approaches to the task of building such agents. We will then focus on the symbolic approach, showing how intelligence is the result of the interplay between knowledge and reasoning, and discussing the declarative, procedural and structured ways of dealing with knowledge representation and reasoning. We will conclude with simple examples from areas of learning, planning and natural language understanding. T4 - Design of Expert Systems (in Portuguese - 3.10.95 PM) Ernesto Morgado The objective of this tutorial is to introduce the key ideas about expert systems. What are the problems that require them? What makes expert systems different from other programs? What are the main techniques used by them? What are the different types of expert systems available today? How can they be integrated with other problems in the real world? How can they be developed successfully? These and many other aspects must be understood for someone who desires to develop expert systems in the real world. The Venue ~~~~~~~~~ Madeira is an island in the northern half of the Atlantic Ocean about 1,000 km from Lisbon. It is 57 km long and 22 km wide. The landscape is vernal and luxuriant: the rich flora, with its diversity of trees and flowers, exist in a truly sub-tropical environment. The population of the entire island is approximately 280,000, and that of the capital, Funchal, is approximately 140,000. Climate and Dress ~~~~~~~~~~~~~~~~~ At the beginning of October, the temperature ranges from 22C to 25C (72F to 77F) during the day, and 20C to 22C (68F to 72F) at night. Lightweight clothing is therefore recommended. However, if you plan to visit the mountain areas of the island, it is recommended that you bring a jacket. The island does receive rain from time to time during this part of the year, so it is advisable to bring an umbrella. Transport and Accommodations ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The trip from the airport to the hotels in Funchal is by bus. The round trip from the airport to the Congress Hotel is included in the conference fee only for those who make their airline reservations through JFM Tours - the EPIA 95 official travel agency. If you take a cab from the airport, be prepared to pay from 3000 PTE (daytime working days, without luggage) to around 5000 PTE for the trip from the airport terminal to the Casino Park Hotel. (Note that these are merely rough estimates.) All tickets issued by JFM Tours will not be restricted as to the minimum number of days of stay, and tickets can therefore be changed on request. Hotels ~~~~~~ Casino Park Hotel ------------------- The conference is held in Casino Park Hotel, which includes a casino and a conference center. It is one of the finest five-star hotels on the island. For your convenience, EPIA 95 has booked a limited number of rooms at reduced conference rates.

These methods allow automatic tuning of the network size what one generally does empirically with an important risk of over-estimation or under-estimation, implying an untractable computation consuming trial/error procedure.The main questions to address when dealing with evolutive architectures are: 1. How to estimate the new unit(s) parameters ? 2. How to connect this(these) unit(s) to the previous network so that is possible to carry on learning without restarting ? 3. When to stop the adding process ? We recently published in NPL (Neural Processing letters in January 1995) a paper presenting our new incremental procedure for supervised learning with noisy data. Each step consists in adding to the current network a new unit which is trained to learn the error of the network. The incremental step is repeated until the error of the current network reduce to the noise in the data. The stopping criterion is very simple and can be directly deduced from a statistical test on the estimated parameters of the new unit. Some experimental results on function approximation tasks point out the efficacy of this new incremental scheme especially to avoid spurious minima and to design a network with a well-suited size. The number of basic operations is also decreased and gives an average gain on convergence speed of about 20%. For more information, consult: ============================= C.Jutten and R.Chentouf.

The network exhibits some degree of interference when new sequences are acquired. It is proven that the model is capable of incrementally learning a finite number of complex sequences. The model is then evaluated with a large set of highly correlated sequences. While the number of intact sequences increases linearly with the number of previously acquired sequences, the amount of retraining due to interference appears to be independent of the size of existing memory. The model is extended to include a chunking network which detects repeated subsequences between and within sequences. The chunking mechanism substantially reduces the amount of retraining in sequential training. Thus, the network investigated here constitutes an effective sequential memory. Various aspects of such a memory are discussed at the end of the paper.

We are constructing a large scale-model of the cerebellum and associated premotor circuits that is constrained by the anatomy and physiology, but that is also abstract to allow us to explore its control abilities in a computationally feasible manner. We are specifically focusing on the learning of skilled reaching behavior. The post doc will stongly interact with physiologists in collaborating laboratories who study motor control in animals, but should be most skilled in computational approaches to motor control and in adaptive neural network simulation. If you are interested in this position, which will be available this Fall, or in additional details, please contact Gwyn Mitchell (mitchell@cs.umass.edu, tel (413) 545-1309, fax (413) 545-1249).

Malthouse Key words: nonparametric regression, partial least squares (PLS), principal components regression (PCR), projection pursuit regression (PPR), feedforward neural networks, nonlinear feature extraction, principal components analysis (PCA), nonlinear principal components analysis (NLPCA), principal curves and surfaces. A B S T R A C T We propose a new nonparametric regression method for high-dimensional data, nonlinear partial least squares (NLPLS). NLPLS is motivated by projection-based regression methods, e.g., partial least squares (PLS), projection pursuit (PPR), and feedforward neural networks. The model takes the form of a composition of two functions. The first function in the composition projects the predictor variables onto a lower-dimensional curve or surface yielding scores, and the second predicts the response variable from the scores. We implement NLPLS with feedforward neural networks. NLPLS will often produce a more parsimonious model (fewer score vectors) than projection-based methods, and the model is well suited for detecting outliers and future covariates requiring extrapolation. The scores are also shown to have useful interpretations. We also extend the model for multiple response variables and discuss situations when multiple response variables should be modeled simultaneously and when they should be modeled with separate regressions. We provide empirical results from mathematical and chemical engineering examples which evaluate the performances of PLS, NLPLS, PPR, and three-layer neural networks on (1) response variable predictions, (2) model parsimony, (3) computational requirements, and (4) robustness to starting values. The curves and surfaces used by NLPLS are motivated by the nonlinear principal components analysis (NLPCA) method of doing nonlinear feature extraction. We develop certain properties of NLPCA and discuss its relation to the principal curve method. Both methods attempt to reduce the dimension of a set of multivariate observations by fitting a curve through the middle of the observations and projecting the observations onto this curve. The two methods fit their models under a similar objective function, with one important difference: NLPCA defines the function which maps observed variables to scores (projection index) to be continuous. We show that the effects of this constraint are (1) NLPCA is unable to model curves and surfaces which intersect themselves and (2) the NLPCA ``projections'' are suboptimal producing larger approximation error. We show how NLPCA score values can be interpreted and give the results of a small simulation study comparing the two methods.
