In many domains we are faced with the problem of aggregating a collection of numerical readings to obtain a so-called mean or typical value. The main object of this talk deals with the aggregation procedures used in multicriteria decision making problems. In.such problems, values to be aggregated are gathered in a score table and represent evaluations of alternatives according to various criteria. Aggregation operators are proposed to obtain a global score for each alternative taking into account the given criteria. These global scores are then exploited to establish a recommendation or prescription. In many problems it is important to take into consideration the interaction between criteria. Until recent1y, criteria were supposed to be independent and the aggregation operator which was often used was the weighted arithmetic mean, with all its well-known drawbacks. Such an operator is not suitable when interacting criteria are considered. However, this problem has been overcome by the contribution of fuzzy integrals, such as the Choquet and Sugeno integrals.

Where and how does the brain discriminate familiar and unfamiliar faces? This question has not been answered yet by neuroimaging studies partly because different tasks were performed on familiar and unfamiliar faces, or because familiar faces were associated with semantic and lexical information. Here eight subjects were trained during 3 days with a set of 30 faces. The familiarized faces were morphed with unfamiliar faces. Presented with continua of unfamiliar and familiar faces in a pilot experiment, a group of eight subjects presented a categorical perception of face familiarity: there was a sharp boundary in percentage of familiarity decisions between 40% and 60% faces. In the main experiment, subjects were scanned (PET) on the fourth day (after 3 days of training) in six conditions, all requiring a sex classification task. Completely novel faces (0%) were presented in Condition 1 and familiar faces (100%) in Condition 6, while faces of steps of 20% in the continuum of familiarity were presented in Conditions 2 to 5 (20% to 80%). A principal component analysis (PCA) indicated that most variations in neural responses were related to the dissociation between faces perceived as familiar (60% to 100%) and faces perceived as unfamiliar (0 to 40%). Subtraction analyses did not disclose any increase of activation for faces perceived as familiar while there were large relative increases for faces perceived as unfamiliar in several regions of the right occipito-temporal visual pathway. These changes were all categorical and were observed mainly in the right middle occipital gyrus, the right posterior fusiform gyrus, and the right inferotemporal cortex. These results show that (1) the discrimination between familiar and unfamiliar faces is related to relative increases in the right ventral pathway to unfamiliar/novel faces; (2) familiar and unfamiliar faces are discriminated in an all-or-none fashion rather than proportionally to their resemblance to stored representations; and (3) categorical perception of faces is associated with abrupt changes of brain activity in the regions that discriminate the two extremes of the multidimensional continuum.

An overview of the use of the discrete Sugeno integral as either an aggregation tool or a preference functional is presented in the qualitative framework of two decision paradigms: multi-criteria decision-making and decision-making under uncertainty. The parallelism between the representation theorems in both settings is stressed, even if a basic requirement like the idempotency of the aggregation scheme should be explicitely stated in multi-criteria decision-making, while its counterpart is implicit in decision under uncertainty by equating the utility of a constant act with the utility of its consequence. Important particular cases of Sugeno integrals such as prioritized minimum and maximum operators, their ordered versions, and Boolean max-min functions are studied. [less ▲]

The goal of this paper is to replicate and extend the connectionist model presented by Mareschal and French(1997) as an account of 'the particularities of […] infant memory and categorization'. With infants, the sequential presentation of cats followed by dogs yields an expected increase in infants' looking time, whereas the reversed presentation order does not. This intriguing asymmetry of infants' category formation, first reported by Quinn, Eimas, and Rosenkrantz (1993), was simulated by Mareschal et al.'s simple connectionist network. In addition, the authors proposed that this asymmetric categorization is a natural b yproduct of the 'asymmetric overlaps of the visual feature distributions' of cats and dogs. Using a simple feed forward backpropagationnetwork, we successfully replicated this asymmetric categorization effect, as well as a reported asymmetric exclusivity effect in the two categories, and anasymmetric interference effect of learning dogs on the memory for cats, but not of learning cats on the memory for dogs. We furthermore investigated the authors'explanation of the asymmetric effects, firstly, by systematically varying the overall similarity between learned items and interfering items, and secondly, by adding a binary feature to the input set, namely the animal cry (barking vs. mewing). The results of the present modeling underscore the authors' explanation of the observed effects in infants' memory and categorization, but also suggest lines of further experimental research susceptible to undermine the proposed connectionist account.
