Deep Learning for Computer Graphics: Learning to Estimate Lighting From Photographs

We propose an automatic method to infer high dynamic range illumination from a single, limited field-of-view, low dynamic range photograph of a scene. In contrast to previous work that relies on specialized image capture, user input, and/or simple scene models, we train an end-to-end deep neural network that directly regresses a limited field-of-view photo to HDR illumination, without strong assumptions on scene geometry, material properties, or lighting. This allows us to automatically recover high-quality HDR illumination estimates that significantly outperform previous state-of-the-art methods. Consequently, using our illumination estimates for applications like 3D object insertion, we can achieve compelling, photorealistic results.

Can You Trust Your Model's Uncertainty? Evaluating Predictive Uncertainty Under Dataset Shift

Modern machine learning methods including deep learning have achieved great success in predictive accuracy for supervised learning tasks, but may still fall short in giving useful estimates of their predictive uncertainty. Quantifying uncertainty is especially critical in real-world settings, which often involve input distributions that are shifted from the training distribution due to a variety of factors including sample bias and non-stationarity. In such settings, well calibrated uncertainty estimates convey information about when a model's output should (or should not) be trusted. Many probabilistic deep learning methods, including Bayesian-and non-Bayesian methods, have been proposed in the literature for quantifying predictive uncertainty, but to our knowledge there has not previously been a rigorous large-scale empirical comparison of these methods under dataset shift. We present a large-scale benchmark of existing state-of-the-art methods on classification problems and investigate the effect of dataset shift on accuracy and calibration. We find that traditional post-hoc calibration does indeed fall short, as do several other previous methods. However, some methods that marginalize over models give surprisingly strong results across a broad spectrum of tasks.

Advances in Deep Architectures and Methods for Separating Vocals in Recorded Music

Source separation of audio mixtures, with an emphasis on the human voice, remains one of the enticing unsolved challenges in audio signal processing. This challenge is amplified in the context of recorded music, where often many sound sources are intentionally correlated in both time and frequency. In this talk, we present recent advances in the state of the art for separating singing voice and accompaniment in popular music audio recordings, leveraging semi-supervised datasets mined from a large commercial music catalog. In addition, we explore the effects of combining deep convolutional U-Net architectures with multi-task learning for vocal separation.

Deep Learning, Where Are You Going?

There are three axes along which advances in machine learning and deep learning happen. They are (1) network architectures, (2) learning algorithms and (3) spatio-temporal abstraction. In this talk, I will describe a set of research topics I've pursued in each of these axes. For network architectures, I will describe how recurrent neural networks, which were largely forgotten during 90s and early 2000s, have evolved over time and have finally become a de facto standard in machine translation. I continue on to discussing various learning paradigms, how they related to each other, and how they are combined in order to build a strong learning system. Along this line, I briefly discuss my latest research on designing a query-efficient imitation learning algorithm for autonomous driving. Lastly, I present my view on what it means to be a higher-level learning system. Under this view each and every end-to-end trainable neural network serves as a module, regardless of how they were trained, and interacts with each other in order to solve a higher-level task. I will describe my latest research on trainable decoding algorithm as a first step toward building such a framework.

Deep Learning in Speech Recognition

While neural networks had been used in speech recognition in the early 1990s, they did not outperform the traditional machine learning approaches until 2010, when Alex’s team members at Microsoft Research demonstrated the superiority of Deep Neural Networks (DNN) for large vocabulary speech recognition systems. The speech community rapidly adopted deep learning, followed by the image processing, and many other disciplines. In this talk I will explain the transition to deep learning, what the speech recognition field has accomplished, and the remaining challenges.

The Next Generation of AI Chips

Deep learning has fuelled significant progress in computer vision, speech recognition, and natural language processing. We have seen a single deep learning algorithm learn to recognize two vastly different languages, English and Mandarin, begin to synthesize realistic human speech, recognize visual data, and even to understand human language. At Baidu, we think that this is just the beginning, and high performance computing is poised to help. It turns out that deep learning is compute limited, even on the fastest machines that we can build. This talk will focus on a new discovery that significantly accelerates deep learning training by using mixed 16-bit and 32-bit IEEE standard floating point arithmetic. Unlike previous work in this area, the first generation of commodity hardware realizing an up to 8x speedup from this approach is already shipping in volume. We demonstrate the success of this approach across 15 state of the art deep learning training applications drawn from a diverse set of problem domains, and detail the small changes to deep learning frameworks needed to support this technology.

Learning from Video: Recognizing Actions and Localizing Moments with Natural Language

This talk will describe two works in video understanding. In the first part, I will describe ActionVLAD, a new video representation for action classification that aggregates local convolutional features across an entire spatio-temporal extent of a video. In the second part, I will describe an approach that retrieves a specific temporal segment (moment) from a video given a natural language text description. We address lack of video datasets for this task by collecting the Distinct Describable Moments (DiDeMo) dataset which consists of over 10,000 unedited, personal videos in diverse visual settings with pairs of localized video segments and referring expressions.

Unsupervised Domain Adaptation with Adversarial Network

This talk presents our recent work on using Adversarial learning to improve the recognition task in the presence of domain shifts or bias between the source (training) and target (testing) domains. Our new approach factors the learned feature space of both source domains and target domains into discriminative space and reconstructive space, where the discriminative space captures class-specific information while the reconstructive space captures the domain-specific information. A GAN-loss is used to minimize the domain shifts in the discriminative space between the two domains for better generalization performance. Our preliminary results show the promise of our approach, achieving new state-of-the-art results on standard cross-domain digit classification tasks.

Composing Graphical Models With Neural Networks for Structured Representations and Fast Inference

How can we build structured, but flexible models? We propose a general modeling and inference framework that combines the complementary strengths of probabilistic graphical models and deep learning methods. Our model family combines latent graphical models with neural network observation models. All components are trained simultaneously with a single scalable stochastic variational objective. We illustrate this framework with several example models, and by showing how to automatically segment and categorize mouse behavior from raw video.

Divide and Conquer Networks

Many engineering and scientific tasks require solving algorithmic tasks at scale under computational constraints. In general, these constraints are hard to optimize in closed form, motivating the use of data-driven algorithmic learning. Rather than studying this as a black-box discrete regression problem with no assumption whatsoever on the input-output mapping, we concentrate on tasks that are amenable to the principle of divide and conquer, and study what are its implications in terms of learning. This principle creates a powerful inductive bias that can be leveraged with neural architectures that are defined recursively and dynamically, by learning two scale-invariant atomic operations: how to split a given input into smaller sets, and how to merge two partially solved tasks into a larger partial solution. Thanks to the dynamic aspect of such architecture, computational complexity can be incorporated as a regularization term that can be optimized by backpropagation. In this talk, we will illustrate the flexibility and efficiency of the Divide-and-Conquer Network on combinatorial and geometric tasks, such as sorting, clustering and convex hulls.

Explainable by Design AI is the Real Challenge

Artificial Intelligence capabilities are set to become pervasive and to spread across a span a various systems including air, ground and sea transportation vehicles. Yet Machine Learning algorithms and their derived features do not provide any means to insure and enforce Safety and Security which is the number 1 driver and priority to certify new technologies on board critical transportation systems: “deployable AI can only be achieved with Explainable AI”. To cope with the inherent unpredictability and the lack of guarantees of Machine Learning black boxes, Industry, Academia and Regulations Agencies have to work jointly to design and develop frameworks and Explainable by design AI to allow deployable AI features onboard Aircrafts, Ships and any ground transportation vehicles.
