Fundamental Limits on Data Acquisition: Trade-offs between Sample Complexity and Query Difficulty [article]

Hye Won Chung, Ji Oon Lee, Alfred O. Hero
2018 arXiv   pre-print
We analyze the fundamental trade-offs between the query difficulty and the sample complexity, and show that the sample complexity of n=c{k,(k k)/d̅} for some constant c>0 is necessary and sufficient to  ...  We consider query-based data acquisition and the corresponding information recovery problem, where the goal is to recover k binary variables (information bits) from parity measurements of those variables  ...  CONCLUSIONS In this paper, we analyzed the fundamental trade-offs between query difficultyd and sample complexity n in a query-based data acquisition system associated with a crowdsourcing task with workers  ...

Data acquisition and cost-effective predictive modeling

Foster Provost, Prem Melville, Maytal Saar-Tsechansky
2007 Proceedings of the ninth international conference on Electronic commerce - ICEC '07  
We also present and demonstrate briefly a unified framework within which one can integrate acquisitions of different types, with any cost structure and any predictive modeling objective.  ...  Electronic commerce is revolutionizing the way we think about data modeling, by making it possible to integrate the processes of (costly) data acquisition and model induction.  ...  Acknowledgments We thank Mikhail Bilenko, Panos Ipeirotis, and Ronny Kohavi for enlightening discussions of predictive modeling and data acquisition for electronic commerce.  ...

Critical Factors of Pre-Acquisition Due Diligence in Cross-Border Acquisitions [chapter]

Alen Sacek
2016 Contemporary Studies in Economic and Financial Analysis  
The empirical evidence is data sample of acquisitions made in the automotive manufacturing firms and their cross-border acquisitions in the European automotive industry.  ...  Despite the intense effort, the made progress is still fragmented and lacks unifying theories that approaches the whole acquisition process on the one side, and in-depth research of critical factors on  ...  Investigating pre-acquisition due diligence is limited by confidentiality and the nonpublic character of the data.  ...

Acquisition of procedures: The effects of example elaborations and active learning exercises

Richard Catrambone, Mashiho Yuasa
2006 Learning and Instruction  
This study explored the effects of active learning and types of elaboration on procedure acquisition (writing database queries).  ...  Training materials emphasized elaborations of conditions for executing actions versus elaborations of the connection between conditions and actions.  ...  The apparent trade-off between training time and test time clearly needs to be examined under a variety of training conditions, testing conditions, and using a variety of types of learners (e.g., different  ...

Selection of effective contextual information for automatic synonym acquisition

Masato Hagiwara, Yasuhiro Ogawa, Katsuhiko Toyama
2006 Proceedings of the 21st International Conference on Computational Linguistics and the 44th annual meeting of the ACL - ACL '06  
Various methods have been proposed for automatic synonym acquisition, as synonyms are one of the most fundamental lexical knowledge.  ...  To obtain the final representation that we require for synonym acquisition, that is, the co-occurrence between words and their contexts, these relationships must be converted to binary relations, i.e.,  ...  Therefore, in choosing combination of different kinds of context information, one should take into consideration the economical efficiency and trade-off between computational complexity and overall performance  ...

Unsupervised Language Acquisition: Theory and Practice [article]

Alexander Clark
2002 arXiv   pre-print
I carefully examine the interaction between the various components, and show how these algorithms can form the basis for a empiricist model of language acquisition.  ...  I start by examining an a priori argument based on Gold's theorem, that purports to prove that natural languages cannot be learned, and some formal issues related to the choice of statistical grammars  ...  Here, I use it to refer to a range of techniques that trade off model complexity against the fit of the model against the data, in an attempt to reduce some of the problems of overtraining associated with  ...

Hybridization in Mergers and Acquisitions

Daniel Dauber
2011 Social Science Research Network  
Abstract According to numerous studies, mergers and acquisitions (M&As) tend to fail more often than being profitable.  ...  Moreover, the outcome of such deals is strongly depending on contextual factors and the acculturation strategy chosen to harmonize existing cultural values, strategies, organizational structures and operations  ...  However, the significance of co-occurrences allowed to (1) run more complex queries on qualitative data and (2) systematically identify and define relationships between qualitative and quantitative data  ...

Confidence-based progress-driven self-generated goals for skill acquisition in developmental robots

Hung Ngo, Matthew Luciw, Alexander Förster, Jürgen Schmidhuber
2013 Frontiers in Psychology  
We formulate curiosity-driven exploration, and eventual skill acquisition, as a selective sampling problem. Each environment setting provides the agent with a stream of instances.  ...  Results show that the proposed method generates sample-efficient curious exploration behavior, which exhibits developmental stages, continual learning, and skill acquisition, in an intrinsically-motivated  ...  The planning step helps to trade off "easy-to-get" small learning progress rewards with "harder-toget" larger ones.  ...

Whole cell, label free protein quantitation with data independent acquisition: Quantitation at the MS2 level

Peter McQueen, Vic Spicer, John Schellenberg, Oleg Krokhin, Richard Sparling, David Levin, John A. Wilkins
2014 Proteomics  
Data independent acquisition (DIA) is a newly developed method that should be able to solve these limitations and improve our ability to analyze the proteome.  ...  However, DDA is limited in its ability to analyze the proteome, in that it only selects the most abundant ions for analysis, and different protein identifications can result even if the same sample is  ...  So in SRM there is a trade-off in the amount of proteins that can be quantified, with high sensitivity and lower limits of quantitation.  ...
