Currently, mobile computing devices cannot be seamlessly and flexibly obtain information about the context in which computing takes place. This requires dedicated personalization and localization in combination with advanced autocustomization techniques in order to adapt them to the needs of the current context. For natural interaction, for instance, many devices offer different input and output modalities, which enable different modes of operation to perform the same task. Auto-customization of modalities and devices in range can be obtained, if the system has sufficient information on the user’s preferences, abilities, the current situation, and the device that performs a specific task. To aid the system’s decision, we propose a set of interrelated and expandable profiles, which are prepared for automated adaptation, what will play a central part in making the technology to become invisible.","lang":"eng"}],"place":"Acapulco, Mexico","user_id":"5786","citation":{"bibtex":"@inproceedings{Schäfer_Müller_2003, place={Acapulco, Mexico}, title={Adaptive profiles for Multi-Modal Interaction in Intelligent Frameworks}, booktitle={Proceedings of the Joint Workshop IJCAI Workshop on Artificial Intelligence, Information Access, and Mobile Computing}, author={Schäfer, Robbie and Müller, Wolfgang}, year={2003} }","ama":"Schäfer R, Müller W.

Since the Karhunen-Loeve expansion in its known form is only valid for proper processes, we derive the improper version of this expansion. It produces two sets of eigenvalues and an improper internal description. We use the Karhunen-Loeve expansion to solve the problem of detecting non-stationary improper complex random signals in additive white Gaussian noise. Using the deflection criterion we compare the performance of conventional processing, which ignores complementary covariances, with processing that takes these into account. The performance gain can be as great as a factor of 2."}],"intvolume":"         6","doi":"10.1109/ICASSP.2003.1201782","author":[{"last_name":"Schreier","full_name":"Schreier, Peter J.","first_name":"Peter J."},{"last_name":"Scharf","full_name":"Scharf, Louis L.","first_name":"Louis L."}],"title":"The Karhunen-Loève expansion of improper complex random signals with applications in detection"},{"citation":{"ieee":"T.

Initially, we develop this beamformer by generalizing the Capon (MVDR) optimization problem. That is, if the objective is to minimize output power while maintaining a specified directional gain, then we show that the output power of the widely-linear beamformer is less than or equal to the output power of the Capon (MVDR) beamformer. This result is valid regardless of the “true” distribution of the data. We also derive the widely-linear beamformer by considering beamforming to be an estimation problem. Linear models assume that the composite covariance matrix formed from the real and imaginary parts of the array-snapshot has a particular structure. This structure is often summarized by stating that the covariance formed from the array snapshot and its transpose (not Hermitian transpose) is zero. We could also call these data “proper” Gaussian vectors. The beamformers in this paper are appropriate for situations in which these implicit assumptions are violated."}],"page":"753–759","_id":"40900","volume":1,"date_updated":"2023-01-30T11:52:45Z","date_created":"2023-01-30T11:52:09Z","publication":"Proc. 37th\\ Asilomar Conf.\\ Signals Syst.\\ Computers","type":"conference","year":"2003","status":"public"},{"citation":{"apa":"Schreier, P.
