Image Choice to Represent the Self in Different Online Environments

This paper draws from ‘impression management theory’ to examine the choices individuals make to visually represent themselves on Facebook and Twitter. We interviewed 20 participants about their image choice and the sorts of inferences others make about their identity. Participants were asked whether they believed their image influenced the types of people who connect with them, and whether thei...

Learning to represent visual input

One of the central problems in computational neuroscience is to understand how the object-recognition pathway of the cortex learns a deep hierarchy of nonlinear feature detectors. Recent progress in machine learning shows that it is possible to learn deep hierarchies without requiring any labelled data. The feature detectors are learned one layer at a time and the goal of the learning procedure...

Using Models to Represent Reality

1. Introduction. There has recently been an increase in interest in the role of models in science, of which the Pavia workshop on model-based reasoning is a manifestation. One result of this increased attention has been a proliferation of views on what models are and how they are used in science. In this presentation I will develop a unified interpretation of the nature and role of models in sc...

How to Represent Measurement Errors ?

What is the set of possible values of a measurement error? In the majority of practical applications, an error is caused not by a single cause; it is caused by a large number of independent causes, each of which adds a small component to the total error. As a result, we get a geometric description of the area of possible values of error. In this paper, we formulate the known result (for 1-dimen...
