Grounding Language about Belief in a Bayesian Theory-of-Mind

no code implementations16 Feb 2024 Lance Ying, Tan Zhi-Xuan, Lionel Wong, Vikash Mansinghka, Joshua Tenenbaum

In this paper, we take a step towards an answer by grounding the semantics of belief statements in a Bayesian theory-of-mind: By modeling how humans jointly infer coherent sets of goals, beliefs, and plans that explain an agent's actions, then evaluating statements about the agent's beliefs against these inferences via epistemic logic, our framework provides a conceptual role semantics for belief, explaining the gradedness and compositionality of human belief attributions, as well as their intimate connection with goals and plans.


How does the primate brain combine generative and discriminative computations in vision?

no code implementations11 Jan 2024 Benjamin Peters, James J. DiCarlo, Todd Gureckis, Ralf Haefner, Leyla Isik, Joshua Tenenbaum, Talia Konkle, Thomas Naselaris, Kimberly Stachenfeld, Zenna Tavares, Doris Tsao, Ilker Yildirim, Nikolaus Kriegeskorte

The alternative conception is that of vision as an inference process in Helmholtz's sense, where the sensory evidence is evaluated in the context of a generative model of the causal processes giving rise to it.

Planning with Sequence Models through Iterative Energy Minimization

no code implementations28 Mar 2023 Hongyi Chen, Yilun Du, Yiye Chen, Joshua Tenenbaum, Patricio A. Vela

In this paper, we suggest an approach towards integrating planning with sequence models based on the idea of iterative energy minimization, and illustrate how such a procedure leads to improved RL performance across different tasks.

Discovering Generalizable Spatial Goal Representations via Graph-based Active Reward Learning

no code implementations24 Nov 2022 Aviv Netanyahu, Tianmin Shu, Joshua Tenenbaum, Pulkit Agrawal

To address this, we propose a reward learning approach, Graph-based Equivalence Mappings (GEM), that can discover spatial goal representations that are aligned with the intended goal specification, enabling successful generalization in unseen environments.

Designing Perceptual Puzzles by Differentiating Probabilistic Programs

no code implementations26 Apr 2022 Kartik Chandra, Tzu-Mao Li, Joshua Tenenbaum, Jonathan Ragan-Kelley

We design new visual illusions by finding "adversarial examples" for principled models of human perception -- specifically, for probabilistic models, which treat vision as Bayesian inference.

Identity-Expression Ambiguity in 3D Morphable Face Models

no code implementations29 Sep 2021 Bernhard Egger, Skylar Sutherland, Safa C. Medin, Joshua Tenenbaum

We demonstrate that non-orthogonality of the variation in identity and expression can cause identity-expression ambiguity in 3D Morphable Models, and that in practice expression and identity are far from orthogonal and can explain each other surprisingly well.
