[more ▼]Humans use facial expressions successfully for conveying their emotional states. However, replicating such success in the human-computer interaction domain is an active research problem. In this paper, we propose deep convolutional neural network (DCNN) for joint learning of robust facial expression features from fused RGB and depth map latent representations. We posit that learning jointly from both modalities result in a more robust classifier for facial expression recognition (FER) as opposed to learning from either of the modalities independently. Particularly, we construct a learning pipeline that allows us to learn several hierarchical levels of feature representations and then perform the fusion of RGB and depth map latent representations for joint learning of facial expressions. Our experimental results on the BU-3DFE dataset validate the proposed fusion approach, as a model learned from the joint modalities outperforms models learned from either of the modalities.

[more ▼]Racial bias can affect the way of processing visual stimuli that are targets of prejudice. Different levels of prejudice and the type of prejudice (implicit vs. explicit) were related to automatic and controlled processes of visual exploration (Hansen Rakhshan, Ho, & Pannasch, 2015). The proposed study aims to extend these findings by including pictures of individuals that belong to different racial and ethnic groups (White, Asian, Black, Latino) and vary in prototypical characteristics. Images of the Chicago Face Database will be presented in an online study. Eye movements will be recorded during the presentation of visual stimuli. We will examine differences in exploratory looking behavior among natives in a western European country and individuals with migratory background.

[more ▼]We present the preliminary findings of a multilingual study on speech errors (‘lapsus linguae’ Meringer and Mayer 1895; Freud, 1901; Meringer, 1908). For the purpose of this presentation, we compiled and analyzed a corpus of video-recordings of twenty short sequences of talk in French, and twenty short sequences of talk in English; all containing mis-performances in oral delivery on behalf of TV hosts and presenters. While briefly discussing previous work and existing models for the classification of errors (Meringer and Mayer 1895; Freud, 1901; Fromkin, 1971, 1973; Dell, Juliano, and Govindjee, 1993; Dziekońska, 2012); we take a multimodal look at the sequential environment of errors in our corpus and analyze whether and how they are ‘acknowledged’ and are ‘repaired’ (Sacks, 1964; Sacks Schegloff, Jefferson, 1977). A close analysis of speakers’ face work reveals that, although not universally, they consistently place a brow raise on the ‘repaired’ material. At times, the lapsus is ‘acknowledged’ with the production of a response cry (Goffman, 1981), in which case, the brow raise is placed on the cry. Regardless of the response cry occurring synchronically with the brow raise; we discuss that it is possible to think of the brow raise as of a ‘change of state token’, (Heritage, 1984b; Schegloff, 2007); thus embodying the local change in speakers’ “state of knowledge, information, orientation or awareness” (Heritage, 1985: 299). Data also suggest a brow raise following the lapse, may transit from emotional display (i.e. surprise – Ekman, 2002, 2003, 2005, 2006) to face-keeping device. Different gestural and postural configurations may occur depending on whether the error is promptly repaired (i.e. straight positioning of the ‘body torque’- Schegloff, 1998) or whether develops into a laughter (i.e. presence of ‘self-adapters’ - Ekman, 2002, 2003, 2005, 2006).

[more ▼]Machine-Learning-as-a-Service has become increasingly popular, with Recommendation-as-a-Service as one of the representative examples. In such services, providing privacy protection for users is an important topic. Reviewing privacy-preserving solutions which were proposed in the past decade, privacy and machine learning are often seen as two competing goals at stake. Though improving cryptographic primitives (e.g., secure multi-party computation (SMC) or homomorphic encryption (HE)) or devising sophisticated secure protocols has made a remarkable achievement, but in conjunction with state-of-the-art recommender systems often yields far-from-practical solutions. We tackle this problem from the direction of machine learning. We aim to design crypto-friendly recommendation algorithms, thus to obtain efficient solutions by directly using existing cryptographic tools. In particular, we propose an HE-friendly recommender system, refer to as CryptoRec, which (1) decouples user features from latent feature space, avoiding training the recommendation model on encrypted data; (2) only relies on addition and multiplication operations, making the model straightforwardly compatible with HE schemes. The properties turn recommendation-computations into a simple matrix-multiplication operation. To further improve efficiency, we introduce a sparse-quantization-reuse method which reduces the recommendation-computation time by $9\times$ (compared to using CryptoRec directly), without compromising the accuracy. We demonstrate the efficiency and accuracy of CryptoRec on three real-world datasets. CryptoRec allows a server to estimate a user's preferences on thousands of items within a few seconds on a single PC, with the user's data homomorphically encrypted, while its prediction accuracy is still competitive with state-of-the-art recommender systems computing over clear data. Our solution enables Recommendation-as-a-Service on large datasets in a nearly real-time (seconds) level.

[more ▼]This paper presents an approach to preservice science teacher education coupling video analysis with dialogue as tools for fostering teachers‟ ability to notice and reflexively interpret events captured during teaching practicum with the intent of transforming classroom practice. In this approach, video becomes a tool with which teachers connect theory and practice, and through dialogue, develop an appreciation for how one can inform the other. Specifically, we explore the role of cogenerative dialogue in structuring individual reflection and ongoing dialogue that help facilitate reflexivity. In doing so, we elaborate on the construct of reflexivity as a potential foundation for changing practices in the science classroom and we illustrate the ways in which reflexivity and action emerged from dialogic encounters around video analysis.

[more ▼]Behavioural studies have shown a relation between numbers and space (DeHevia et al., 2008). Fischer and colleagues (2003) showed that digits can act as central spatial cues in a target detection task, resulting in shorter reaction times (RT) for left-sided targets when preceded by small numbers and for right-sided targets when preceded by large numbers. This facilitation effect indicates that numbers orient visuo-spatial attention to the left or right hemifield, depending on their magnitude. To date no studies investigated whether this facilitation is followed by inhibition of return at longer intervals, as could be expected with visuo-spatial attention shifts. To this aim, we designed an analogous paradigm to Fischer et al.’s, introducing additional longer intervals. Participants (n=25) were presented a task irrelevant digit (1,2 vs. 8,9) for 400ms and had to detect a brief (100ms) lateral target appearing after a variable interval (100, 250, 500, 750, 1000, 1250ms). A 2x6 repeated measures ANOVA of mean RT, with congruency and interval as within-subject variables yielded a significant interaction (F(5,24)=2.3, p<0.05). As expected, targets were detected faster when appearing in the congruent (small-left, large-right) hemifield after 250ms. Using the regression method proposed by Lorch and Myers (1990), the slope at this interval was significantly negative (t(24)=1.70, p=0.05); indicating a facilitation for the detection of targets in the congruent hemifield) (cf. Fischer et al., 2003). At the 1250ms interval, targets were detected significantly slower when they appeared in the congruent compared to the incongruent hemifield (yielding significantly positive slopes at 1250ms: t(24)=2.68, p=0.007). These findings provide the first evidence that digits not only produce facilitation effects at shorter intervals, but also induce inhibitory effects at longer intervals, confirming the visuo-spatial nature of the attention shifts associated with Arabic digits.

[more ▼]Human ageing represents one of the major challenges of Europe in the upcoming decades given that nine of the 10 oldest world populations are from Europe. This has and will have evident consequences at all levels of the socio-ecological context. It is thus a challenge for Psychology and especially Geropsychology to provide sound research-based knowledge about processes of human ageing as well as expertise about training, education and interventions that will help to promote quality of living and subjective well-being both at the individual and the social level. The symposium follows this notion and scholars from eight European countries will report on new developments in theory and research across the various geropsychology domains that will help to tackle the challenge of ageing. In a first part on “Cognitive decline, aging, and mental health”, the symposium will address clinical aspects of ageing. Di Nuovo (Italy) presents findings on interventions enhancing quality of life of elderly persons with mental deterioration or Mild Cognitive Impairment. R. Drăghici will report on the diagnostic use of drawings by elderly persons with neurocognitive disorders. Stepankova, Kopecek, and Schmand (Czech Republic) focus on positive aspects of ageing presenting findings on cognitive superageing. Gatterer, and Blokesch, (Austria) present the theoretical rationale underlying schematherapy use in older adults. The second part of the symposium addresses “Quality of life, aging, and health behaviour” and presents findings on personal and contextual factors that have an impact on these criteria. Fernández-Ballesteros, Angeles Molina and Sánchez Izquierdo (Spain) report findings on contextual influences in social images about ageing, testing predictions of the Stereotype Content Model. Lang and Damm (Germany) present theory and research findings on perceiving future time and its impact on preparing for old age. Despot Lucanin, Lucanin, Bjelajac and Delale (Croatia) present findings on the predictive contributions of psychosocial factors to life satisfaction in old adults. Finally, Ferring and Boll (Luxembourg) give insights into perceived gains and losses when caring for an older relative and their implications for psychosocial intervention.

[more ▼]Safety-critical real-time systems, including real-time cyber-physical and industrial control systems, need not be solely correct but also timely. Untimely (stale) results may have severe consequences that could render the control system’s behaviour hazardous to the physical world. To ensure predictability and timeliness, developers follow a rigorous process, which essentially ensures real-time properties a priori, in all but the most unlikely combinations of circumstances. However, we have seen the complexity of both real-time applications, and the environments they run on, increase. If this is matched with the also increasing sophistication of attacks mounted to RTES systems, the case for ensuring both safety and security through aprioristic predictability loses traction, and presents an opportunity, which we take in this paper, for discussing current practices of critical realtime system design. To this end, with a slant on low-level task scheduling, we first investigate the challenges and opportunities for anticipating successful attacks on real-time systems. Then, we propose ways for adapting traditional fault- and intrusiontolerant mechanisms to tolerate such hazards. We found that tasks which typically execute as analyzed under accidental faults, may exhibit fundamentally different behavior when compromised by malicious attacks, even with interference enforcement in place.
