Resum In the frame of the research project undertaken in the site of La Draga, an Early Neolithic (ca. 5,300-4,800 cal BC) pile-dwelling settlement located at the North Eastern of the Iberian Peninsula, we are developing a serious game that recreates the life of a Neolithic community with the purpose of dissemination, entertainment and learning. The videogame has tried to provide the most relia...

The problem of projective reconstruction for multiple views is considered using a factorization method. A common difficulty of existing formulations of the factorization problem is that they do not adequately constrain the depth parameters thus allowing the algorithm to converge to view-deficient solutions with entire views being suppressed. We propose to include a variance measure with an adap...

Covariate measurement error and missing responses are typical features in longitudinal data analysis. There has been extensive research on either covariate measurement error or missing responses, but relatively little work has been done to address both simultaneously. In this paper, we propose a simple method for the marginal analysis of longitudinal data with time-varying covariates, some of w...

In this paper we present a method of data decomposition to avoid the necessity of reasoning on data with missing attribute values. The original incomplete data is decomposed into data subsets without missing values. Next, methods for classifier induction are applied to such sets. Finally, a conflict resolving method is used to combine partial answers from classifiers to obtain final classificat...

Robustness aspects of nested balanced incomplete block designs against missing data have been investigated using connectedness and efficiency criteria. Sufficient condition for robustness of a design has been obtained for the loss of any m observations, using connectedness criterion. Designs robust against the loss of any m observations belonging to one sub-block, loss of any two observations b...

This paper considers the resolution of ambiguity according to the scientific ideal of direct observation when there is a practical necessity for social learning. An agent faces ambiguity when she directly observes low-quality data yielding set-identified signals. I suppose the agent’s objective is to choose the single belief replicating what would occur with high-quality data yielding pointiden...

We are deeply grateful to the discussants for providing constructive and stimulating comments and suggestions. Our paper gives a survey of recent optimality and adaptivity results on estimating various families of structured covariance and precision matrices in the high-dimensional setting, with a focus on understanding the intrinsic difficulty of the problems. To achieve this goal, we present ...
