The Phrontistery: Obscure Words and Vocabulary Resources Model Thinking This course will consist of twenty sections. As the course proceeds, I will fill in the descriptions of the topics and put in readings. Section 1: Introduction: Why Model? In these lectures, I describe some of the reasons why a person would want to take a modeling course. These reasons fall into four broad categories: To be an intelligent citizen of the worldTo be a clearer thinkerTo understand and use dataTo better decide, strategize, and design There are two readings for this section. The Model Thinker: Prologue, Introduction and Chapter 1 Why Model? Section 2: Sorting and Peer Effects We now jump directly into some models. In this second section, I show a computational version of Schelling's Segregation Model using NetLogo. NetLogo The Schelling Model that I use can be found by clicking on the "File" tab, then going to "Models Library". The readings for this section include some brief notes on Schelling's model and then the academic papers of Granovetter and Miller and Page. Six Sigma V.S.
I, Cringely . The Pulpit . War of the Worlds There is a technology war coming. Actually it is already here but most of us haven't yet notice. It is a war not about technology but because of technology, a war over how we as a culture embrace technology. It is a war that threatens venerable institutions and, to a certain extent, threatens what many people think of as their very way of life. It is a war that will ultimately and inevitably change us all, no going back. The early battles are being fought in our schools. This is a war over how we as a culture and a society respond to Moore's Law. The real power of Moore's Law lies in what the lady at the bank called "the miracle of compound interest," which has allowed personal computers to increase in performance a millionfold over the past 30 years. The key word here is "empowerment." Let's be clear about what we're measuring here. I came to this conclusion recently while attending Brainstorm 2008, a delightful conference for computer people in K-12 schools throughout Wisconsin.
How sense and respond organizations differ from make and sell organizations. | Sense & Respond S&R as Post-Industrial Managerial Paradigm An adaptive management paradigm is the missing element in current attempts to transform businesses into adaptive organizations. Because adaptive behavior is typically unplanned—often ad hoc– it is intrinsically inefficient and therefore persistently undermined by the existing efficiency-centric management paradigm. The metrics and practices fostered by this industrial age model frustrate attempts to empower people, inculcate a customer orientation, leverage adaptive technologies, and respond to unanticipated change. Those firms that have made a degree of progress in becoming more adaptive (or at least more agile or resilient) have typically relied on what Bruce Harreld of IBM called “the heroic model” of management – counting on exceptionally talented people to break the rules without breaking too much glass. Sense & Respond is a robust replacement of the legacy managerial paradigm. The Transformational Foundations of Sense & Respond

Verbal learning. Abstract Pioneering work in the 1940s and 1950s suggested that the concept of ‘chunking’ might be important in many processes of perception, learning and cognition in humans and animals.

Artificial neural network An artificial neural network is an interconnected group of nodes, akin to the vast network of neurons in a brain. Here, each circular node represents an artificial neuron and an arrow represents a connection from the output of one neuron to the input of another. For example, a neural network for handwriting recognition is defined by a set of input neurons which may be activated by the pixels of an input image. Like other machine learning methods - systems that learn from data - neural networks have been used to solve a wide variety of tasks that are hard to solve using ordinary rule-based programming, including computer vision and speech recognition. Background There is no single formal definition of what an artificial neural network is. consist of sets of adaptive weights, i.e. numerical parameters that are tuned by a learning algorithm, andare capable of approximating non-linear functions of their inputs.
