Changing Forward versus Changing Back

Changing the Probability versus Changing the Reward

There are two means of changing the expected value of a risk: changing the probability of a reward or changing the reward. Theoretically, the former produces a greater change in expected utility for risk averse agents. This paper uses two formats of a risk preference elicitation mechanism under two decision frames to test this hypothesis. After controlling for decision error, probability weight...

Improving Back Propagation of Feed-Forward Neural Network with Changing Sigmoid Functions

Our study is about feed-forward neural network’s learning method. Generally, the method of improving its learning is focused on learning rate and moment term. We focus on sigmoid functions. Sigmoid functions are used for converting input signal into output signal and adjusting connection weight of learning in feed-forward neural network. We change gradient of sigmoid functions and investigate o...

Changing perceptions, changing reality.

Changing families, changing workplaces.

American families and workplaces have both changed dramatically over the past half-century. Paid work by women has increased sharply, as has family instability. Education-related inequality in work hours and income has grown. These changes, says Suzanne Bianchi, pose differing work-life issues for parents at different points along the income distribution. Between 1975 and 2009, the labor force ...

Changing Minds, Changing Brains

Measures of brain function are used today in many areas of psychological research, and developmental psychology is no exception. The infusion of cognitive neuroscience into psychology has been met variably with enthusiasm, skepticism, and opposition. The most productive attitude towards this sea change, I maintain, consists of a healthy dose of both enthusiasm and skepticism [see also Kagan, 20...
