Least angle regression

by Bradley Efron, Trevor Hastie, Iain Johnstone, Robert Tibshirani , 2004
"... The purpose of model selection algorithms such as All Subsets, Forward Selection and Backward Elimination is to choose a linear model on the basis of the same set of data to which the model will be applied. Typically we have available a large collection of possible covariates from which we hope to s ..."

to select a parsimonious set for the efficient prediction of a response variable. Least Angle Regression (LARS), a new model selection algorithm, is a useful and less greedy version of traditional forward selection methods. Three main properties are derived: (1) A simple modification of the LARS algorithm

Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,

by ] Richard Hackman , Grec R Oldham , 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

An Algebraic Receiver for Full Response CPM

by Aline Neves, Mamadou Mboup, Michel Fliess
"... Abstract—This paper proposes a new algebraic demodulation method for full response CPM signals in AWGN channel. The method is based in a new estimation/identification theory that has also already been used for channel identification and signal deconvolution. The signals and noise are considered to b ..."

Phase Smoothing Functions For Full Response CPM

by D. Asano, H. Leib, S. Pasupathy - In Proc. IEEE Pacific Rim Conference on Communications, Computers and Signal Processing , 1989
"... Continuous Phase Modulation (CPM) is examined for low complexity receivers, i.e., those that operate on only one symbol interval. The tradeoff between the bandwidth and bit error rate (BER) performance of these simple systems is studied. The phase smoothing functions that minimize the effective band ..."

Continuous Phase Modulation (CPM) is examined for low complexity receivers, i.e., those that operate on only one symbol interval. The tradeoff between the bandwidth and bit error rate (BER) performance of these simple systems is studied. The phase smoothing functions that minimize the effective bandwidth for a given BER are calculated. A linear and a polynomial approximation to these phase smoothing functions are chosen. The three families are compared using their bandwidth -- BER performance tradeoffs, power spectral densities, out--of-- band powers and bandwidth efficiencies. It is shown that CPM schemes with small modulation indices (h 0:5) offer good tradeoffs between bandwidth and BER performance. 1. Introduction The binary signaling scheme that gives the best bit error rate (BER) performance with one symbol interval demodulation is obtained when antipodal signals are used. For carrier modulation, Binary Phase Shift Keying (BPSK) is the most commonly used scheme. However, when ...

Measuring praise and criticism: Inference of semantic orientation from association

by Peter D. Turney, Michael L. Littman - ACM Transactions on Information Systems , 2003
"... The evaluative character of a word is called its semantic orientation. Positive semantic orientation indicates praise (e.g., “honest”, “intrepid”) and negative semantic orientation indicates criticism (e.g., “disturbing”, “superfluous”). Semantic orientation varies in both direction (positive or neg ..."

An automated system for measuring semantic orientation would have application in text classification, text filtering, tracking opinions in online discussions, analysis of survey responses, and automated chat systems (chatbots).
