1, 2, 3, More: An Accumulator Architecture for Anchoring and Adjustment
نویسنده
چکیده
We present a computational model of probabilistic reasoning in a synthetic task environment. The task is a solitaire game called TRACS in which a player must update odds as card are turned, like Blackjack. Initial experiments with this game showed that human subjects exhibit a “baseline bias” due to a heuristic strategy of “anchoring and adjustment”. Here we develop a computational model of this behavior using fuzzy functions and simple summing to simulate the cognitive processes of memory activation and evidence accumulation. We compare the simulation results to experimental data and highlight the practical value of our approach.

A Novel Multiply-Accumulator Unit Bus Encoding Architecture for Image Processing Applications
In the CMOS circuit power dissipation is a major concern for VLSI functional units. With shrinking feature size, increased frequency and power dissipation on the data bus have become the most important factor compared to other parts of the functional units. One of the most important functional units in any processor is the Multiply-Accumulator unit (MAC). The current work focuses on the develop...
متن کاملOptimal Control of a New Hydraulic Elevator Architecture
This study presents application of Dynamic Programming towards finding globally optimal control policies of a new, highly-efficient hydraulic elevator architecture. The architecture employs an actuator, three accumulators, and two hydraulic circuits bridged by a hydraulic transformer. An auxiliary electric motor exists only to compensate for system losses. Prior research identified a multitude ...
متن کاملPutting adjustment back in the anchoring and adjustment heuristic: differential processing of self-generated and experimenter-provided anchors.
People's estimates of uncertain quantities are commonly influenced by irrelevant values. These anchoring effects were originally explained as insufficient adjustment away from an initial anchor value. The existing literature provides little support for the postulated process of adjustment, however, and a consensus that none takes place seems to be emerging. We argue that this conclusion is prem...
متن کاملFloating accumulator architecture
Although technology advancement can pack more and more physical registers in processors, the numbers of architectured registers defined by the instruction set architectures (ISAs) remain relatively small on most modern processors. Exposing more architectured registers to compilers and programmers can improve the effectiveness of compiler optimization and the quality of code. However, increasing...
متن کاملA New Architecture for Decimating FIR Filter
A new architecture for decimating finite impulse response filters is proposed. The architecture is based on using a number of accumulators; each one accumulates a partial sum corresponding to a unique set of D filter coefficients into the filter output, where D is the decimation factor. In the new decimating filter, the accumulated result of an accumulator is passed to another accumulator once ...
