For wide sense stationary (WSS) Gaussian processes, this is a problem of deciding between two different power spectral density matrices, one of them diagonal. Specifically, we show that for arbitrary Gaussian processes (not necessarily WSS) the generalized likelihood ratio test (GLRT) is given by the quotient between the determinant of the sample space-time covariance matrix and the determinant of its block-diagonal version. Furthermore, for WSS processes, we present an asymptotic frequency-domain approximation of the GLRT which is given by a function of the Hadamard ratio (quotient between the determinant of a matrix and the product of the elements of the main diagonal) of the estimated power spectral density matrix. The Hadamard ratio is known to be the GLRT detector for vector-valued random variables and, therefore, what this paper shows is how frequency-dependent Hadamard ratios must be merged into a single test statistic when the vector-valued random variable is replaced by a vector-valued time series with temporal correlation. For bivariate time series, the derived frequency domain detector can be rewritten as a function of the well-known magnitude squared coherence (MSC) spectrum, which suggests a straightforward extension of the MSC spectrum to the general case of multivariate time series.

It is envisoned that agents will learn from humans by simply interacting with each other. In such a scenario, learning by interaction {\textquoteright}goes beyond common supervised or unsupervised strategies by taking into account wider feedback and assessments for the learning processes{\textquoteright} (1 p.140). So far, little is known about interactional processes and feedback strategies involved. Yet, in order to learn, a learner will typically need to be provided with information given by a teacher who not only gives certain structure to the interaction but also instructs for and demonstrates the learning contents. The given information can only be effective, if the learner is receptive. To assure this, the tutor makes use of interactive regularities checking the learner{\textquoteright}s behavior. The term contingency has been suggested to encompass such regu- larities in interaction. More specifically, it refers to a temporal sequence of behavior and reaction (2, 3). It has been shown that contingency is an important factor in interactions with infants and contributes to the cognitive development of infants 4. In the interaction with an artificial agent, contingency has been operationalized by eye-gaze bouts 5. So far, it has been shown that while in a situation with a child, eye-gaze bouts in total, average and frequency is much higher as in interaction with an adult as learner. In a situation with an artificial agent, a decrease of eye-gaze bouts could be observed 5. It could thus be reasoned that tutor{\textquoteright}s monitoring behavior is impaired when interacting with a robot. However, so far only an interaction with a virtual robot has been investigated. In contrast, an embodied robot could evoke a more natural tutor behavior. In this study, we therefore investigated a tutoring situation with an embodied robot and focused on tutor{\textquoteright}s monitoring behavior. We followed the minimal definition of embodiment by K. Dautenhahn et al. to quantify the difference in embodiment between these two systems 6. Accordingly, the Degrees of Embodiment (DOM) are calculated as:DOMS,E = f (x, y, t), where system S in respect to an environment E is calculated by a function f of the vectors x and y and the time t. x describes the number of sensors, the detected modalities of the sensors and the channels of information provided by the sensors, y describes the degree of freedom (DoF) of the robot. In our experiments E remained unchanged and thus the DOM is not affected by this factor. We argue that in our case, the function f is only dependent on the degrees of freedom of the robot. Possibly, we can give a value which represents the difference in the degree of embodiment (DDOM). Since our goal was to study some characteristics of contingency (7, 5), our dependent variable was the tutor{\textquoteright}s monitoring behavior operationalized by the eye-gaze.}}, author = {{Lohan, Katrin Solveig and Gieselmann, Sebastian and Vollmer, Anna-Lisa and Rohlfing, Katharina and Wrede, Britta}}, booktitle = {{International Conference on Development and Learning}}, publisher = {{IEEE}}, title = {{{Does embodiment affect tutoring behavior?}}}, year = {{2010}}, } @article{17256, author = {{Grimminger, Angela and Rohlfing, Katharina and Stenneken, Prisca}}, issn = {{1569-9773}}, journal = {{Gesture}}, keywords = {{task- oriented dialogue, Late Talker, maternal multimodal input, gestural motherese}}, number = {{2}}, pages = {{251--278}}, publisher = {{John Benjamins Publishing Company}}, title = {{{Children's lexical skills and task demands affect gestural behavior in mothers of late-talking children and children with typical language development}}}, doi = {{10.1075/gest.10.2-3.07gri}}, volume = {{10}}, year = {{2010}}, }
