A survey of induction algorithms for machine learning

Central to all systems for machine learning from examples is an induction algorithm. The purpose of the algorithm is to generalize from a finite set of training examples a description consistent with the examples seen, and, hopefully, with the potentially infinite set of examples not seen. This paper surveys four machine learning induction algorithms. The knowledge representation schemes and a PDL description of algorithm control are emphasized. System characteristics that are peculiar to a domain of application are de-emphasized. Finally, a comparative summary of the learning algorithms is presented

Towards an observational economics of business behaviour: the horizontal supply curve, 'fuzzy' demand and other anomalies for conventional theory

This paper proposes the development of an 'observational economics' whose domain would be restricted to what is observable in the real world. Observational economics should be regarded as a separate but complementary undertaking to mainstream economics. Adoption of such an approach would enhance the reestablishment and development of interaction between economists and the business community. Phenomena such as price setting, unpredictable and variable demand, and inventories and order backlogs are argued to be anomalous from the viewpoint of conventional microeconomics, but fundamental to an observational perspective on business behaviour. A basic observational model of price and output determination for the price setting manufacturing firm is outlined.observational economics; business behaviour; horizontal supply curve; fuzzy demand; inventories; order backlogs
