Quantifying artificial intelligence through algebraic generalization

no code implementations8 Nov 2024 Takuya Ito, Murray Campbell, Lior Horesh, Tim Klinger, Parikshit Ram

Thus, algebraic circuit complexity theory - the study of algebraic expressions as circuit models (i. e., directed acyclic graphs) - is a natural framework to study the complexity of symbolic computation.

Neural Reasoning Networks: Efficient Interpretable Neural Networks With Automatic Textual Explanations

1 code implementation10 Oct 2024 Stephen Carrow, Kyle Harper Erwin, Olga Vilenskaia, Parikshit Ram, Tim Klinger, Naweed Aghmad Khan, Ndivhuwo Makondo, Alexander Gray

Recent advances in machine learning have led to a surge in adoption of neural networks for various tasks, but lack of interpretability remains an issue for many others in which an understanding of the features influencing the prediction is necessary to ensure fairness, safety, and legal compliance.

Learning positional encodings in transformers depends on initialization

no code implementations12 Jun 2024 Takuya Ito, Luca Cocchi, Tim Klinger, Parikshit Ram, Murray Campbell, Luke Hearne

Critically, we find that the choice of initialization of a learnable PE greatly influences its ability to learn accurate PEs that lead to enhanced generalization.

What makes Models Compositional? A Theoretical View: With Supplement

no code implementations2 May 2024 Parikshit Ram, Tim Klinger, Alexander G. Gray

We then show how various existing general and special purpose sequence processing models (such as recurrent, convolution and attention-based ones) fit this definition and use it to analyze their compositional complexity.

Compositional Program Generation for Few-Shot Systematic Generalization

1 code implementation28 Sep 2023 Tim Klinger, Luke Liu, Soham Dan, Maxwell Crouse, Parikshit Ram, Alexander Gray

Compositional generalization is a key ability of humans that enables us to learn new concepts from only a handful examples.

Compositional generalization through abstract representations in human and artificial neural networks

no code implementations15 Sep 2022 Takuya Ito, Tim Klinger, Douglas H. Schultz, John D. Murray, Michael W. Cole, Mattia Rigotti

Our findings give empirical support to the role of compositional generalization in human behavior, implicate abstract representations as its neural implementation, and illustrate that these representations can be embedded into ANNs by designing simple and efficient pretraining procedures.

Hierarchical Reinforcement Learning with AI Planning Models

1 code implementation1 Mar 2022 JunKyu Lee, Michael Katz, Don Joven Agravante, Miao Liu, Geraud Nangue Tasse, Tim Klinger, Shirin Sohrabi

Our approach defines options in hierarchical reinforcement learning (HRL) from AIP operators by establishing a correspondence between the state transition model of AI planning problem and the abstract state transition system of a Markov Decision Process (MDP).

Consolidation via Policy Information Regularization in Deep RL for Multi-Agent Games

no code implementations23 Nov 2020 Tyler Malloy, Tim Klinger, Miao Liu, Matthew Riemer, Gerald Tesauro, Chris R. Sims

This paper introduces an information-theoretic constraint on learned policy complexity in the Multi-Agent Deep Deterministic Policy Gradient (MADDPG) reinforcement learning algorithm.

Deep RL With Information Constrained Policies: Generalization in Continuous Control

no code implementations9 Oct 2020 Tyler Malloy, Chris R. Sims, Tim Klinger, Miao Liu, Matthew Riemer, Gerald Tesauro

We focus on the model-free reinforcement learning (RL) setting and formalize our approach in terms of an information-theoretic constraint on the complexity of learned policies.

A Study of Compositional Generalization in Neural Models

no code implementations16 Jun 2020 Tim Klinger, Dhaval Adjodah, Vincent Marois, Josh Joseph, Matthew Riemer, Alex 'Sandy' Pentland, Murray Campbell

One difficulty in the development of such models is the lack of benchmarks with clear compositional and relational task structure on which to systematically evaluate them.

Efficient Black-Box Planning Using Macro-Actions with Focused Effects

2 code implementations28 Apr 2020 Cameron Allen, Michael Katz, Tim Klinger, George Konidaris, Matthew Riemer, Gerald Tesauro

Focused macros dramatically improve black-box planning efficiency across a wide range of planning domains, sometimes beating even state-of-the-art planners with access to a full domain model.

CAPACITY-LIMITED REINFORCEMENT LEARNING: APPLICATIONS IN DEEP ACTOR-CRITIC METHODS FOR CONTINUOUS CONTROL

We formalize this type of bounded rationality in terms of an information-theoretic constraint on the complexity of policies that agents seek to learn.

Logical Rule Induction and Theory Learning Using Neural Theorem Proving

e-QRAQ: A Multi-turn Reasoning Dataset and Simulator with Explanations

no code implementations5 Aug 2017 Clemens Rosenbaum, Tian Gao, Tim Klinger

In this paper we present a new dataset and user simulator e-QRAQ (explainable Query, Reason, and Answer Question) which tests an Agent's ability to read an ambiguous text; ask questions until it can answer a challenge question; and explain the reasoning behind its questions and answer.

Multiresolution Recurrent Neural Networks: An Application to Dialogue Response Generation

4 code implementations2 Jun 2016 Iulian Vlad Serban, Tim Klinger, Gerald Tesauro, Kartik Talamadupula, Bo-Wen Zhou, Yoshua Bengio, Aaron Courville

We introduce the multiresolution recurrent neural network, which extends the sequence-to-sequence framework to model natural language generation as two parallel discrete stochastic processes: a sequence of high-level coarse tokens, and a sequence of natural language tokens.
