Abstract:
Classification techniques have been applied to real world problems such as fish classification and email sorting. In this work, we introduce a new application called ANIMAL. ANIMAL is a Machine Learning Disc Jockey. A model for beat (from music) and bop (from head motion) is proposed. Using this model, we treat a listener's musical enjoyment as a classification problem. We define a beat/bop similarity metric based on harmonic matching over frequencies in the Fourier domain across the raw inputs (windowed proportionally to heterogeneous sampling rates, uncovered empirically). From our similarity metric, we define features which we use in a number of classification methods. We use both generative and discriminative methods such as Logistic Regression, Naive Bayes, Stochastic Gradient Linear Regression and Support Vector Machines (SVMs). We have results for a test set comprised of a 33% set aside from our corpus of data. We compare the performance of these methods among different sets of features extracted from the harmonic match. Our results show that the Naive Bayes Classifier outperforms the aforementioned classification techniques.2003

Abstract:
The problem of multi-source integration of scientific data requires detailed knowledge of the representational formats for all data sources participating in the application. An instance of such a system is a sensori-motor network. In such a system, the position of a subject is maintained as it moves about an instrumented space. Visual sensory modes extract salient regions of interest as potential subjects to be tracked from pictures taken from their viewpoint of a scene. We must ensure that feature vectors computed from such regions of one sensor refer to the same object in the world viewed by another sensor as pose can affect a sensor's response. Across a multi-modal sensor system, data can differ in any combination of resolution, feature vector representation, and mode. I examine the matching problem in a multi-modal sensorimotor network. Using a Convergent Computing approach for integrating poly-lingual systems, I treat feature vectors as object oriented types. With meta-information on a feature vector's structure, equivalences between two different representations can be found through a series of transformations. As disparate sensory modes diverge in their information content and semantics, the integration problem becomes more difficult. In stochastic domains, feedback from the environment can improve matching.2001

Abstract:
Applications of multiple processors embedded in the systems involved with entertainment, informatics, climate control, communication, transportation, and food preparation are already commonplace. A network of these embedded processors presents application development challenges since the state space grows exponentially as new devices attach to the network. The programming model for such systems will need to change if reliable systems are to be realized. By observing information about sensorimotor activity, such systems can gather information useful to programming the network. Through such interaction, a network can build hierarchies of shareable computational structures for representing various activities. This application domain presents additional challenges due to disparate sensor and actuator bandwidth, hardware disparities and partial system failure. We present an architecture that fuses sensing and control with the Jini Network Technology in a distributed sensorimotor network. This network can grow dynamically over time and facilitates the automatic creation of persistent data structures.2000

Abstract:
Robot control in nonlinear and nonstationary run-time environments presents challenges to traditional software methodologies. In particular, robot systems in "open" domains can only be modeled probabilistically and must rely on run-time feedback to detect whether hardware/software configurations are adequate. Modifications must be effected while guaranteeing critical performance properties. Moreover, in multi-robot systems, there are typically many ways in which to compensate for inadequate performance. The computational complexity of high dimensional sensorimotor systems prohibits the use of many traditional centralized methodologies. We present an application in which a redundant sensor array, distributed spatially over an office-like environment can be used to track and localize a human being while reacting at run-time to various kinds of faults, including: hardware failure, inadequate sensor geometries, occlusion, and bandwidth limitations. Responding at run-time requires a combination of knowledge regarding the physical sensorimotor device, its use in coordinated sensing operations, and high-level process descriptions. We present a distributed control architecture in which run-time behavior is both preanalyzed and recovered empirically to inform local scheduling agents that commit resources autonomously subject to process control specifications. Preliminary examples of system performance are presented from the UMass Self-Adaptive Software (SAS) platform.
