Task and Object Learning in Visual Recognition
(1991-01-01)
Human performance in object recognition changes with practice, even in the absence of feedback to the subject. The nature of the change can reveal important properties of the process of recognition. We report an ...
The Kineticist's Workbench: Combining Symbolic and Numerical Methods in the Simulation of Chemical Reaction Mechanisms
(1991-05-01)
The Kineticist's Workbench is a program that simulates chemical reaction mechanisms by predicting, generating, and interpreting numerical data. Prior to simulation, it analyzes a given mechanism to predict that ...
Pose Determination of a Grasped Object Using Limited Sensing
(1991-05-01)
This report explores methods for determining the pose of a grasped object using only limited sensor information. The problem of pose determination is to find the position of an object relative to the hand. The information ...
Phase Space Navigator: Towards Automating Control Synthesis in Phase Spaces for Nonlinear Control Systems
(1991-04-01)
We develop a novel autonomous control synthesis strategy called Phase Space Navigator for the automatic synthesis of nonlinear control systems. The Phase Space Navigator generates global control laws by synthesizing ...
Nonlinear Analog Networks for Image Smoothing and Segmentation
(1991-01-01)
Image smoothing and segmentation algorithms are frequently formulatedsas optimization problems. Linear and nonlinear (reciprocal) resistivesnetworks have solutions characterized by an extremum principle. Thus,sappropriately ...
Extracting and Representing Qualitative Behaviors of Complex Systems in Phase Spaces
(1991-03-01)
We develop a qualitative method for understanding and representing phase space structures of complex systems and demonstrate the method with a program, MAPS --- Modeler and Analyzer for Phase Spaces, using deep domain ...
Control Algorithms for Chaotic Systems
(1991-03-01)
This paper presents techniques that actively exploit chaotic behavior to accomplish otherwise-impossible control tasks. The state space is mapped by numerical integration at different system parameter values and ...
Programmable Applications: Interpreter Meets Interface
(1991-10-01)
Current fashion in "user-friendly'' software design tends to place an overreliance on direct manipulation interfaces. To be truly expressive (and thus truly user-friendly), applications need both learnable interfaces ...
Apparent Opacity Affects Perception of Structure from Motion
(1991-01-01)
The judgment of surface attributes such as transparency or opacity is often considered to be a higher-level visual process that would make use of low-level stereo or motion information to tease apart the transparent ...
Revised Report On The Algorithmic Language Scheme
(1991-11-01)
Data and procedures and the values they amass, Higher-order functions to combine and mix and match, Objects with their local state, the message they pass, A property, a package, the control of point for a catch- In the ...
