We determine the computational complexity of the Hahn-Banach Extension Theorem. To do so, we investigate some basic connections between reverse mathematics and computable analysis. In particular, we use Weak König’s Lemma within the framework of computable analysis to classify incomputable functions of low complexity. By defining the multi-valued function Sep and a natural notion of reducibilit...
متن کاملGUIDO/MIR - an Experimental Musical Information Retrieval System based on GUIDO Music Notation
Musical databases are growing in number, size, and complexity, and they are becoming increasingly relevant for a broad range of academic as well as commercial applications. The features and performance of musical database systems critically depend on two factors: The nature and representation of the information stored in the database, and the search and retrieval mechanisms available to the use...
متن کاملMassachusetts Institute of Technology Guido
In this lecture we are concerned with models for stationary (in the weak sense) processes. The focus here will be on linear processes. This is clearly restrictive given the stylized facts of financial time series. However linear time series models are often used as building blocks in nonlinear models. Moreover linear models are easier to handle empirically and have certain optimality properties...
متن کاملClinical evaluation of Guido robotic walker.
The Guido is a robotic walker that provides navigation and obstacle-avoidance assistance. Engineering tests have found that the device performs adequately and presents no hazard to the user. The performance of the Guido was compared with a low-tech mobility aid, the Assistive Mobility Device (AMD) developed at the Atlanta Department of Veterans Affairs Medical Center, in trials involving older ...
متن کاملExtrapolation and Bubbles
We present an extrapolative model of bubbles. In the model, many investors form their demand for a risky asset by weighing two signals—an average of the asset’s past price changes and the asset’s degree of overvaluation. The two signals are in conflict, and investors “waver” over time in the relative weight they put on them. The model predicts that good news about fundamentals can trigger large...
