Reinforcement Learning in POMDPs With Memoryless Options and Option-Observation Initiation Sets
Proceedings of the AAAI Conference on Artificial Intelligence, 2018 Many real-world reinforcement learning problems have a hierarchical nature, and often exhibit some degree of partial observability. While hierarchy and partial observability are usually tackled separately (for instance by combining recurrent neural networks and options), we show that addressing both problems simultaneously is simpler ...

Context-dependent choice and evaluation in real-world consumer behavior
Scientific Reports, 2022 A body of work spanning neuroscience, economics, and psychology indicates that decision-making is context-dependent, which means that the value of an option depends not only on the option in question, but also on the other options in the choice set—or ...

INFERENCE FOR OPTION PANELS IN PURE-JUMP SETTINGS [PDF]
Econometric Theory, 2018 We develop parametric inference procedures for large panels of noisy option data in a setting, where the underlying process is of pure-jump type, i.e., evolves only through a sequence of jumps. The panel consists of options written on the underlying asset with a (different) set of strikes and maturities available across the observation times.

Ciencias Marinas, 2002 Concordance analysis, a multicriteria technique, was used as a decision-making tool. To exemplify the use of this tool, five closure options were evaluated to decrease incidental catch of mahi-mahi or dolphin-fish, Coryphaena spp., by the Mexican ...

Option Pricing in an Investment Risk-Return Setting [PDF]
SSRN Electronic Journal, 2019 In this paper, we combine modern portfolio theory and option pricing theory so that a trader taking a position in a European option contract, the underlying assets, and a risk-free bond can constru...

A comparative analysis of 2-option and 3-option response formats for computerized work aptitude test [PDF]
SHS Web of ConferencesThis study aims to identify the optimal response format for a work aptitude test by evaluating its psychometric properties. This study employed a quantitative, quasi-experimental method utilizing a post-test only control group design.

Abnormal returns, risk, and options in large data sets [PDF]
Statistica Neerlandica, 1998 Large data sets in finance with millions of observations have become widely available. Such data sets enable the construction of reliable semi‐parametric estimates of the risk associated with extreme price movements. Our approach is based on semi‐parametric statistical extreme value analysis, and compares favorably with the conventional finance normal ...

A fuzzy approach to option pricing in a Levy process setting [PDF]
International Journal of Applied Mathematics and Computer Science, 2013 Abstract In this paper the problem of European option valuation in a Levy process setting is analysed. In our model the underlying asset follows a geometric Levy process. The jump part of the log-price process, which is a linear combination of Poisson processes, describes upward and downward jumps in price.
