Value-based Fast and Slow AI Nudging

no code implementations14 Jul 2023 Marianna B. Ganapini, Francesco Fabiano, Lior Horesh, Andrea Loreggia, Nicholas Mattei, Keerthiram Murugesan, Vishal Pallagani, Francesca Rossi, Biplav Srivastava, Brent Venable

Values that are relevant to a specific decision scenario are used to decide when and how to use each of these nudging modalities.

Plansformer: Generating Symbolic Plans using Transformers

no code implementations16 Dec 2022 Vishal Pallagani, Bharath Muppasani, Keerthiram Murugesan, Francesca Rossi, Lior Horesh, Biplav Srivastava, Francesco Fabiano, Andrea Loreggia

Large Language Models (LLMs) have been the subject of active research, significantly advancing the field of Natural Language Processing (NLP).

Learning Behavioral Soft Constraints from Demonstrations

no code implementations21 Feb 2022 Arie Glazier, Andrea Loreggia, Nicholas Mattei, Taher Rahgooy, Francesca Rossi, Brent Venable

Many real-life scenarios require humans to make difficult trade-offs: do we always follow all the traffic rules or do we violate the speed limit in an emergency?

Making Human-Like Trade-offs in Constrained Environments by Learning from Demonstrations

no code implementations22 Sep 2021 Arie Glazier, Andrea Loreggia, Nicholas Mattei, Taher Rahgooy, Francesca Rossi, K. Brent Venable

To this end, we propose a novel inverse reinforcement learning (IRL) method for learning implicit hard and soft constraints from demonstrations, enabling agents to quickly adapt to new settings.

Data-driven Small-signal Modeling for Converter-based Power Systems

no code implementations30 Aug 2021 Francesca Rossi, Eduardo Prieto-Araujo, Marc Cheah-Mane, Oriol Gomis-Bellmunt

This article details a complete procedure to derive a data-driven small-signal-based model useful to perform converter-based power system related studies.

E-PDDL: A Standardized Way of Defining Epistemic Planning Problems

no code implementations19 Jul 2021 Francesco Fabiano, Biplav Srivastava, Jonathan Lenchner, Lior Horesh, Francesca Rossi, Marianna Bergamaschi Ganapini

Epistemic Planning (EP) refers to an automated planning setting where the agent reasons in the space of knowledge states and tries to find a plan to reach a desirable state from the current state.

Learning and Recognizing Archeological Features from LiDAR Data

no code implementations5 Apr 2020 Conrad M Albrecht, Chris Fisher, Marcus Freitag, Hendrik F. Hamann, Sharathchandra Pankanti, Florencia Pezzutti, Francesca Rossi

We present a remote sensing pipeline that processes LiDAR (Light Detection And Ranging) data through machine & deep learning for the application of archeological feature detection on big geo-spatial data platforms such as e. g. IBM PAIRS Geoscope.

Modeling Contrary-to-Duty with CP-nets

no code implementations23 Mar 2020 Roberta Calegari, Andrea Loreggia, Emiliano Lorini, Francesca Rossi, Giovanni Sartor

In a ceteris-paribus semantics for deontic logic, a state of affairs where a larger set of prescriptions is respected is preferable to a state of affairs where some of them are violated.

Voting with Random Classifiers (VORACE): Theoretical and Experimental Analysis

no code implementations18 Sep 2019 Cristina Cornelio, Michele Donini, Andrea Loreggia, Maria Silvia Pini, Francesca Rossi

In many machine learning scenarios, looking for the best classifier that fits a particular dataset can be very costly in terms of time and resources.

Using deceased-donor kidneys to initiate chains of living donor kidney paired donations: algorithms and experimentation

no code implementations17 Dec 2018 Cristina Cornelio, Lucrezia Furian, Antonio Nicolo', Francesca Rossi

We design a flexible algorithm that exploits deceased donor kidneys to initiate chains of living donor kidney paired donations, combining deceased and living donor allocation mechanisms to improve the quantity and quality of kidney transplants.

Building Ethically Bounded AI

no code implementations10 Dec 2018 Francesca Rossi, Nicholas Mattei

We envision a modular approach where any AI technique can be used for any of these essential ingredients in decision making or decision support systems, paired with a contextual approach to define their combination and relative weight.

CPMetric: Deep Siamese Networks for Learning Distances Between Structured Preferences

no code implementations21 Sep 2018 Andrea Loreggia, Nicholas Mattei, Francesca Rossi, K. Brent Venable

CPDist is a novel metric learning approach based on the use of deep siamese networks which learn the Kendal Tau distance between partial orders that are induced by compact preference representations.

Interpretable Multi-Objective Reinforcement Learning through Policy Orchestration

no code implementations21 Sep 2018 Ritesh Noothigattu, Djallel Bouneffouf, Nicholas Mattei, Rachita Chandra, Piyush Madan, Kush Varshney, Murray Campbell, Moninder Singh, Francesca Rossi

To ensure that agents behave in ways aligned with the values of the societies in which they operate, we must develop techniques that allow these agents to not only maximize their reward in an environment, but also to learn and follow the implicit constraints of society.

Incorporating Behavioral Constraints in Online AI Systems

no code implementations15 Sep 2018 Avinash Balakrishnan, Djallel Bouneffouf, Nicholas Mattei, Francesca Rossi

To define this agent, we propose to adopt a novel extension to the classical contextual multi-armed bandit setting and we provide a new algorithm called Behavior Constrained Thompson Sampling (BCTS) that allows for online learning while obeying exogenous constraints.

Towards Composable Bias Rating of AI Services

no code implementations31 Jul 2018 Biplav Srivastava, Francesca Rossi

The possibly biased behavior of a service is hard to detect and handle if the AI service is merely being used and not developed from scratch, since the training data set is not available.
