Initial Experiments with Statistical Conjecturing over Large Formal Corpora
"... Abstract. A critical part of mathematicians' work is the process of conjecture-making. This involves observing patterns in and between mathematical objects, and transforming such patterns into conjectures that describe or better explain the behavior of the objects. Computer scientists have sin ..."

since long tried to reproduce this process automatically, but most of the methods were typically restricted to specific domains or based on brute-force enumeration methods. In this work we propose and implement methods for generating conjectures by using statistical analogies extracted from large formal
Building a Large Annotated Corpus of English: The Penn Treebank
- COMPUTATIONAL LINGUISTICS
, 1993
"... There is a growing consensus that significant, rapid progress can be made in both text understanding and spoken language understanding by investigating those phenomena that occur most centrally in naturally occurring unconstrained materials and by attempting to automatically extract information abou ..."

In this paper, we review our experience with constructing one such large annotated corpus--the Penn Treebank, a corpus 1 consisting of over 4.5 million words of American English. During the first three-year phase of the Penn Treebank Project (1989
Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

. Pascal conjectured that human choice behavior could be approximated by this procedure. 106 SCHULTZ Despite its advantages, expected value theory has limits when comparing very small with very large rewards or when comparing values at different start positions. Rather than following physical sizes
Whom You Know Matters: Venture Capital Networks and Investment Performance,
- Journal of Finance

"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

VC funds whose parent firms enjoy more influential network positions have significantly better performance, as measured by the proportion of portfolio company investments that are successfully exited through an initial
Developing Corpus-based Translation Methods between Informal and Formal Mathematics: Project Description
"... Abstract. The goal of this project4 is to (i) accumulate annotated infor-mal/formal mathematical corpora suitable for training semi-automated translation between informal and formal mathematics by statistical machine-translation methods, (ii) to develop such methods oriented at the for-malization ta ..."

Automated and human proofs in general mathematics: An initial comparison
- Logic for Programming, Artificial Intelligence, and Reasoning (LPAR-18), Lecture Notes in Computer Science
, 2012
"... Abstract. First-order translations of large mathematical repositories allow dis-covery of new proofs by automated reasoning systems. Large amounts of avail-able mathematical knowledge can be re-used by combined AI/ATP systems, pos-sibly in unexpected ways. But automated systems can be also more easi ..."

Both large-theory AI/ATP methods, and translation and data-mining techniques of large formal corpora, have significantly developed recently, providing enough data for an initial comparison
Discretion within constraint: Homophily and structure in a formal organization
- Organization Science
, 2013
"... H omophily in social relations results from both individual preferences and selective opportunities for interaction, but how these two mechanisms interact in large, contemporary organizations is not well understood. We argue that organizational structures and geography delimit opportunities for int ..."

These findings have implications for research on homophily, gender relations in organizations, and formal and informal
A Grouping Principle and Four Applications
- IEEE Transactions on Pattern Analysis and Machine Intelligence
, 2003
"... Abstract-Wertheimer's theory suggests a general perception law according to which objects having a quality in common get perceptually grouped. The Helmholtz principle is a quantitative version of this general grouping law. It states that a grouping is perceptually "meaningful" if its ..."

In two previous works, we have applied this principle to the detection of orientation alignments and boundaries in a digital image. In this paper, we

Abstract Although many have praised the High/Scope Perry Preschool studies for their alleged revelations about long-term effects of formal preschool, we seriously doubt that a study started 45 years ago strongly applies today, and we are disturbed by the devastating fate of the control group.

Generalized Louvain method for community detection in large networks
"... Abstract—In this paper we present a novel strategy to discover the community structure of (possibly, large) networks. This approach is based on the well-know concept of network modularity optimization. To do so, our algorithm exploits a novel measure of edge centrality, based on the κ-paths. This te ..."
