From Multimodal LLMs to Generalist Embodied Agents: Methods and Lessons

CVPR 2025poster

We examine the capability of Multimodal Large Language Models (MLLMs) to tackle diverse domains that extend beyond the traditional language and vision tasks these models are typically trained on. Specifically, our focus lies in areas such as Embodied AI, Games, UI Control, and Planning. To this end,…

Tell, Draw, and Repeat: Generating and Modifying Images Based on Continual Linguistic Instruction

ICCV 2019poster

Conditional text-to-image generation is an active area of research, with many possible applications. Existing research has primarily focused on generating a single image from available conditioning information in one step. One practical extension beyond one-step generation is a system that generates…

Mutual Information Neural Estimation

ICML 2018oral

We argue that the estimation of mutual information between high dimensional continuous random variables can be achieved by gradient descent over neural networks. We present a Mutual Information Neural Estimator (MINE) that is linearly scalable in dimensionality as well as in sample size, trainable t…

GibbsNet: Iterative Adversarial Inference for Deep Graphical Models

NeurIPS 2017poster

Directed latent variable models that formulate the joint distribution as $p(x,z) = p(z) p(x \mid z)$ have the advantage of fast and exact sampling. However, these models have the weakness of needing to specify $p(z)$, often with a simple fixed prior that limits the expressiveness of the model. Undi…

Iterative Refinement of the Approximate Posterior for Directed Belief Networks

NeurIPS 2016poster

Variational methods that rely on a recognition network to approximate the posterior of directed graphical models offer better inference and learning than previous methods. Recent advances that exploit the capacity and flexibility in this approach have expanded what kinds of models can be trained. Ho…
