Options of Interest: Temporal Abstraction with Interest Functions [article]

Khimya Khetarpal, Martin Klissarov, Maxime Chevalier-Boisvert, Pierre-Luc Bacon, Doina Precup
2020 arXiv   pre-print
We provide a generalization of initiation sets suitable for general function approximation, by defining an interest function associated with an option.  ...  We investigate how interest functions can be leveraged to learn interpretable and reusable temporal abstractions.  ...  Options learned with interest functions emerge with specific interest in different regions of the state. tion (0.3, 0.  ...

Options of Interest: Temporal Abstraction with Interest Functions

We provide a generalization of initiation sets suitable for general function approximation, by defining an interest function associated with an option.  ...  We investigate how interest functions can be leveraged to learn interpretable and reusable temporal abstractions.  ...  Constructing such temporal abstractions automatically from data has also been tackled extensively, and with some success (Konidaris et al. 2011; Figure 6 : Timeline of options used by IOC agent in HalfCheetah  ...

Learning Options with Interest Functions

Khimya Khetarpal, Doina Precup
2019 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
We aim to autonomously learn options which are specialized in different state space regions by proposing a notion of interest functions, which generalizes initiation sets from the options framework for  ...  We build on the option-critic framework to derive policy gradient theorems for interest functions, leading to a new interest-option-critic architecture.  ...  Given a set of Markov options with stochastic, differentiable interest functions I ω,z , the gradient of the expected discounted return with respect to z at (s, ω) is: s ,ω μ Ω (s , ω |s, ω)β ω,ν (s )  ...

Cryonics in the Courtroom: Which Interests? Whose Interests?

Richard Huxtable
2017 Medical Law Review  
Starting with autonomy interests, the judgment implicitly supported a relational account of autonomy, but was dominated by a subjective interpretation of autonomy, which prioritized JS's wishes.  ...  Temporal concerns also feature when we interpret welfare in terms of happiness, because the dying person and the (potential) future reanimated person might have different interests at different times.  ...  In addition to the temporal dilemmas associated with the current and future interests of individual patients, questions arise about whose interests should be in issue, whether current or future.  ...

Profiling interest relativity

Delia Graff Fara
2008 Analysis  
Stanley's claims about the epistemological profile of interest-relative propositions are incorrect. His claims about the modal profile of interest-relative propositions are correct, but not worrisome.  ...  Here I rebut a two-part objection to my interest-relative theory of vagueness in both of these ways. 1 The objection, as developed by Jason Stanley (2003, 2005), concerns the modal and epistemological  ...  This function will of course vary with the adjective in the sentence; when the adjective is 'tall', f (C) is the normal height for C.  ...

On the Role of Weight Sharing During Deep Option Learning

We thus reconsider this assumption and consider more general extensions of option-critic and hierarchical option-critic training that optimize for the full architecture with each update.  ...  In this work we note that while this key assumption of the policy gradient theorems of option-critic holds in the tabular case, it is always violated in practice for the deep function approximation setting  ...  arbitrarily deep option hierarchy with N levels of abstraction.  ...

Common Interest Tragedies

Lee Anne Fennell
2003 Social Science Research Network  
In subpart C, I show how the heterogeneity among production functions associated with the assembly of fragmentary interests provides a meaningful way of weighing these options.  ...  The first Part lays the groundwork for dividing up the universe of common interest tragedies functionally.  ...  However, it is a quite important corner, and the light that the analysis sheds demonstrates the payoff of this Article's taxonomy of common interest tragedies.  ...

User Interests Identification on Twitter Using a Hierarchical Knowledge Base [chapter]

Pavan Kapanipathi, Prateek Jain, Chitra Venkataramani, Amit Sheth
2014 Lecture Notes in Computer Science  
We argue that the hierarchical semantics of concepts can enhance existing systems to personalize or recommend items based on a varied level of conceptual abstractness.  ...  Semantic enrichment of Twitter posts, to determine user interests, has been an active area of research in the recent past.  ...  Further, we want to include temporal aspect to score interests where recently mentioned interests are scored higher.  ...

Exploring OD patterns of interested region based on taxi trajectories

Min Lu, Jie Liang, Zuchao Wang, Xiaoru Yuan
2016 Journal of Visualization  
Traffics of different regions in a city have different Origin-Destination (OD) patterns, which potentially reveal the surrounding traffic context and social functions.  ...  In this work, we present a visual analysis system to explore OD patterns of interested regions based on taxi trajectories.  ...  Particularly, exclusive option provides the function of filtering out trajectories passing a certain area.  ...

Health in turn is a prominent social good that tends to be unequally distributed in the population in function of its accessibility and the conditions of its social production.  ...  This sketch starts with a short recall of some aspects of our socio-economic system's meso-and macro-history, distinguishes three models of macro-economic organization that coexist unequally in present-day  ...  The new systems are of an increasingly flexible application. Their handling demands cognitive functioning on higher levels of abstraction than is the case of more traditional work skills.  ...
