    • U.T.: Telnet Reference Manual 

      Eastlake, Donald E. (1974-04-01)
      UT is a user telnet program designed to run under the ITS time sharing system. It implements the relatively recent ARPA network negotiating protocol for telnet connections.
    • Uncertainty Propagation in Model-Based Recognition 

      Jacobs, D.W.; Alter, T.D. (1995-02-01)
      Building robust recognition systems requires a careful understanding of the effects of error in sensed features. Error in these image features results in a region of uncertainty in the possible image location of each ...
    • Understanding Bandwidth Limitations in Robot Force Control 

      Eppinger, Steven D.; Seering, Warren P. (1987-08-01)
      This paper provides an analytical overview of the dynamics involved in force control. Models are developed which demonstrate, for the one-axis explicit force control case, the effects on system closed-loop bandwidth ...
    • Understanding Hand-Printed Algebra for Computer Tutoring 

      Purcell, Stephen C. (1977-02-01)
      This thesis demonstrates how the use of a global context can improve the power of a local character recognizer. The global context considered is a computer tutor of high school algebra that observes a student working ...
    • Understanding in Incomplete Worlds 

      Rosenberg, Steven (1978-05-01)
      Most real world domains differ from the micro-worlds traditionally used in A.I. in that they have an incomplete factual database which changes over time. Understanding in these domains can be thought of as the generation ...
    • Understanding Text through Summarization and Analogy 

      Tonfoni, Graziella; Doyle, Richard J. (1983-04-01)
      Understanding a text exactly in the way that the Text Producer meant the text to be understood is highly unlikely unless the text interpretation process is constrained. Specific understanding-directing criteria are ...
    • Understanding Understanding Mathematics 

      Michener, Edwina Rissland (1978-08-01)
      In this paper we look at some of the ingredients and processes involved in the understanding of mathematics. We analyze elements of mathematical knowledge, organize them in a coherent way and take note of certain ...
    • A Unified Framework for Regularization Networks and Support Vector Machines 

      Evgeniou, Theodoros; Pontil, Massimiliano; Poggio, Tomaso (1999-03-01)
      Regularization Networks and Support Vector Machines are techniques for solving certain problems of learning from examples -- in particular the regression problem of approximating a multivariate function from sparse ...
    • A Unified Statistical and Information Theoretic Framework for Multi-modal Image Registration 

      Zollei, Lilla; Fisher, John; Wells, William (2004-04-28)
      We formulate and interpret several multi-modal registration methods in the context of a unified statistical and information theoretic framework. A unified interpretation clarifies the implicit assumptions of each method ...
    • UNITRAN: An Interlingual Machine Translation System 

      Dorr, Bonnie Jean (1987-12-01)
      This report describes the UNITRAN (UNIversal TRANslator) system, an implementation of a principle-based approach to natural language translation. The system is "interlingual", i.e., the model is based on universal ...
    • Universality of TAG Systems with P-2 

      Cooke, John; Minsky, Marvin (1963-04-01)
      In the following sections we show, by a simple direct construction, that computations done by Turing machines can be duplicated by a very simple symbol manipulation process. The process is described by a simple form of ...
    • Unrecognizable Sets of Numbers 

      Minsky, Marvin; Papert, Seymour A. (1964-11-01)
      When is a set A of positive integers, represented as binary numbers, "regular" in the sense that it is a set of sequences that can be recognized by a finite-state machine? Let pie A(n) be the number of members of A less ...
    • The Unsupervised Acquisition of a Lexicon from Continuous Speech 

      Marcken, Carl de (1996-01-18)
      We present an unsupervised learning algorithm that acquires a natural-language lexicon from raw speech. The algorithm is based on the optimal encoding of symbol sequences in an MDL framework, and uses a hierarchical ...
    • The Use of Censors for Nonmonotonic Reasoning and Analogy in Medical Desicion-Making 

      Mansour, Hormoz (1985-11-01)
      A patient rarely has a single, isolated disease. The situation is usually much more complex since the different parts of the human organism and metabolism interact with each other and follow several feedback patterns. ...
    • Use of MACDMP 

      Samson, Peter (1965-07-01)
      MACIMP is a PDP-6 program which can load from DECtape to core memory, dump core onto DECtape, or verify a previously dumped filel against memory. Normally, just before it loads, it clears all of memory to 0 (except itself ...
    • The Use of Parallelism to Implement a Heuristic Search 

      Kornfeld, William A. (1981-03-01)
      The role of parallel processing in heuristic search is examined by means of an example (cryptarithmetic addition). A problem solver is constructed that combines the metaphors of constraint propagation and hypothesize-and-test. ...
    • A Useful Algebraic Property of Robinson's Unification Algorithm 

      Hart, Timothy (1965-11-01)
      This memo presupposes some acquaintance with "A Machine Oriented Logic Based on the Resolution Principle", J.A. Robinson, JACM Jan65. The reader unfamiliar with this paper should be able to get a general idea of the ...
    • A User's Guide to the A.I. Group LISCOM LISP Complier: Interim Report 

      Golden, Jeffrey P. (1970-12-01)
      The LISCOM version of the AI group PDP/6 LISP compiler is a descendant of the original Greenblatt-Nelson compiler, and is a friendly sibling to the COMPLR version maintained by Jon L. White. The compiler operates in two ...
    • Uses of Technology to Enhance Education 

      Papert, Seymour A. (1973-06-01)
      Section 1: Schematic outline of project and what we want. Hardly any intellectual content. Section 2: Statement of our goals in general terms. This statement is intended to have serious intellectual content but lacks meaty ...
