A Latent Cause Theory of Classical Conditioning. We identify and formalize a fundamental gradient descent phenomenon resulting in a learning proclivity in over-parameterized neural networks. The ability to understand logical relationships between sentences is an important task in language understanding. Here is a list of my recent publications (in reverse chronological order). In this work, we propose a new family of generative flows on an augmented data space, with an aim to improve expressivity without drastically increasing the computational cost of sampling and evaluation of a lower bound on the likelihood. However, the choice between character or phoneme input can create serious limitations for practical deployment, as direct control of pronunciation is crucial in certain cases. Embodied Question Answering (EQA) is a recently proposed task, where an agent is placed in a rich 3D environment and must act based solely on its egocentric input to answer a given question. We study the use of different reward bonuses that incentives exploration in reinforcement learning. The model predicts a vector of real-valued scalars, named syntactic distances, for each split position in the input sentence. Aaron Courville. Recent breakthroughs in computer vision and natural language processing have spurred interest in challenging multi-modal tasks such as visual question-answering and visual dialogue.

Entropy is ubiquitous in machine learning, but it is in general intractable to compute the entropy of the distribution of an arbitrary continuous random variable. Recent advances in variational inference enable the modelling of highly structured joint distributions, but are limited in their capacity to scale to the high-dimensional setting of stochastic neural networks. We modify and extend it to perform object segmentation, noting that the avoidance of pooling can greatly simplify pixel-wise tasks f...

On the contrary, human composers write music in a nonlinear fashion, scribbling motifs here and there, often revisiting choices previously made. We show that the gap can be upper bounded by some form of dispersion measure of the likelihood ratio, which suggests the bias of variational inference can be reduced by making the distribution of the likelihood ratio more concentrated... Unsupervised domain transfer is the task of transferring or translating samples from a source distribution to a different target distribution. (2013), Bengio, Y., Léonard, N., Courville, A.

CycleGAN was recently proposed for this problem, but critically assumes the underlying inter-domain mapping is approximately deterministic and one-to-one. This paper provides an empirical evaluation of recently developed exploration algorithms within the Arcade Learning Environment (ALE).

In an effort to model this kind of generative process, we propose a neural network-based generative architecture, with latent stochastic variables that span a variable number of time steps. The Teacher Forcing algorithm trains recurrent networks by supplying observed sequence values as inputs during training and using the network's own one-step-ahead predictions to do multi-step sampling.

Reliance on trust and coordination makes Diplomacy the first non-cooperative multi-agent benchmark for complex sequential social dilemmas in a rich environment.

Predicting future frames for a video sequence is a challenging generative modeling task. (2002), Courville, A. C., Touretzky, D. S. (2002). Theoretically, we prove the proposed flow can approximate a Hamiltonian ODE as a universal transport map. It is well known that over-parametrized deep neural networks (DNNs) are an overly expressive class of functions that can memorize even random data with $100\%$ training accuracy. Hi! [1] Ian Goodfellow, Yoshua Bengio, and Aaron Courville (2016). While unsupervised domain translation (UDT) has seen a lot of success recently, we argue that allowing its translation to be mediated via categorical semantic features could enable wider applicability. However, the difficulty of training memory models remains a problem obstructing the widespread use of such models. First, we decompose the learning of VAEs into layerwise density estimation, and argue that having a flexible prior is beneficial to both sample generation and inference.

We propose zoneout, a novel method for regularizing RNNs. While deep reinforcement learning excels at solving tasks where large amounts of data can be collected through virtually unlimited interaction with the environment, learning from limited interaction remains a key challenge. While VAEs can handle uncertainty and model multiple possible future outcomes, they have a tendency to produce blurry predictions.

I also work part-time at Microsoft Research, … Gradient Starvation arises when cross-entropy loss is minimized by capturing only a subset of features relevant for the task, despite the presence of other predictive features that fail to be discovered. To answer this question, we study deep networks using Fourier analysis. Yet, these models often produce inconsistent outputs in goal-oriented language settings as they are not trained to complete the underlying task.
