A Logic for Making Hard Decisions
We tackle the problem of providing engineering decision makers with relevant information extracted from data obtained via a process model based on deliberation and voting. We list examples of potential applications from the area of bug-fix scheduling for software, as well as space-vehicles “go”-“no-go” decision making. In such application domains, important decisions have to be made hastily and...
متن کاملMultilevel Coding : Use of Hard Decisions in
| Multilevel coding (MLC) schemes with powerful softly decodable component codes like turbo codes allow very power and bandwidth eecient digital communication WH95, FHW96, WFH97a]. But the use of the non{ quantized channel output in each stage of the multistage decoding procedure leads to highly complex receivers. In this paper, the employment of hard decision decoding at several coding levels ...
متن کاملLearning Patterns from Images by Combining Soft Decisions and Hard Decisions
We present a novel approach for learning patterns (sub-images) shared by multiple images without prior knowledge about the number and the positions of the patterns in the images. The patterns may undergo kinds of rigid and non-rigid transformations. To reduce the searching space, the images are pre-segmented and represented by attribute relation graphs (ARGs). The problem is then formulated as ...
متن کاملTime for hard decisions on patient-centred professionalism.
Patients want doctors who are competent, respectful, honest and able to communicate with them. That is patient-centred professionalism. Professional self-regulation, as practised hitherto, has failed to achieve this for all patients. In the United Kingdom, a new way of looking at professional regulation has been developed--as a partnership between public and doctors. At its heart is a code of g...
متن کاملOn the Convergence of Iterative Receiver Algorithms Utilizing Hard Decisions
The convergence of receivers performing iterative hard decision interference cancellation (IHDIC) is analyzed in a general framework for ASK, PSK, and QAM constellations. We first give an overview of IHDIC algorithms known from the literature applied to linear modulation and DS-CDMA-based transmission systems and show the relation to Hopfield neural network theory. It is proven analytically tha...
