Many familiar dilemmas that we find in the application of data-driven AI have their origins in technical-mathematical choices that we have made along the way to this version of AI. Several of them might need to be reconsidered in order for the field to move forward. After reviewing some of the current problems related to AI, we trace their cultural, technical and economic origins, then we discuss possible solutions.

Recently, computer vision approaches specially assisted by deep learning techniques have shown unexpected advancements that practically solve problems that never have been imagined to be automatized like face recognition or automated driving. However, food image recognition due to its high complexity and ambiguity, still remains far from being solved. In this project, we focus on how to combine two challenging research lines: deep learning and uncertainty modeling (epistemic and aleatoric uncertainty). After discussing our methodology to advance in this direction, we comment on potential applications, as well as the social and economic impact of the research on food image analysis.

This talk will be about machine learning for science. Deep time refers to many millions of years of world history recorded in sedimentary rocks. The world today captures only a snapshot of ecosystems, environments and climates that can possibly be. Looking at the past is essential for understanding ongoing changes in the natural world, resource use and possible futures. I will discuss computational approaches to reconstructing past worlds and ecosystems, as well as analyzing environmental contexts of human evolution. Very little of deep learning is used so far, although the will is strong. I will highlight the main challenges and will speculate about opportunities.

How can we develop machine learning methods that we can trust in high-risk applications? We need ML methods that know their own range of competence so that they can detect when input queries lie outside that range. This class will present several related areas of ML research that seek to achieve this goal including (a) classification with a "reject" option, (b) calibrated confidence estimation, (c) out of distribution detection, and (d) open category detection. The first two topics focus on problems where the training set and test set come from the same distribution, and the classifier must assess its own competence on each test instance. The second two topics can be viewed as applications of anomaly detection, so we will study anomaly detection methods for both featurized data and for signal data (e.g., images) where a good feature space must be learned. Our discussion of anomaly detection will be complementary to Peter Rousseeuw's course (which makes a good companion).

Inference of functions from data is ubiquitous in Statistical Learning. This course deals with Gaussian process (GP) based approaches that not only learn over a class of nonlinear functions, but also quantify the associated uncertainty. To cope with the curse of dimensionality, random feature Fourier (RF) vectors lead to parametric GP-RF function models, that offer scalable estimators. The course will next focus on online learning with ensembles (E) of GP-RF learners, each with a distinct kernel belonging to a prescribed dictionary, and jointly learning a much richer class of functions. Whether in batch or online forms, EGPs remain robust to dynamics captured by adaptive Kalman filters. Being able to cope with unknown dynamics and quantify uncertainty, are critical especially in adversarial settings. EGP performance can be refined online, and it is benchmarked using regret analysis. Further, the course will cross-fertilize ideas from Deep Gaussian Processes and EGPs in order to gain degrees of freedom. Broader applicability of EGPs will be also demonstrated for interactive optimization and policy evaluation in reinforcement learning.

Deep Learning and 3D Geometry
While Deep Learning in computer vision had been focusing on 2D analysis of images, such as 2D object detection or image segmentation, these recent years have seen the development of many approaches applying the power of Deep Learning to 3D perception from color images, to to solve problems that were very challenging or even impossible a few years ago. Because Deep Learning and 3D geometry come from very different mathematical worlds, one has to find smart ways to connect them, and benefit from These approaches often rely on combinations of Deep Learning applied to 2D images and 3D geometry techniques. In this course, we will review and explain recent approaches to Deep Learning and 3D geometry problems, including 3D object pose estimation, 3D hand pose estimation, feature point detection, self-learning for depth prediction, and 3D scene understanding.

The field of graph signal processing extends classical signal processing tools to signals (data) with an irregular structure that can be characterized my means of a graph (e.g., network data). One of the cornerstones of this field are graph filters, direct analogues of time-domain filters, but intended for signals defined on graphs. In this course, we introduce the field of graph signal processing and specifically give an overview of the graph filtering problem. We look at the family of finite impulse response (FIR) and infinite impulse response (IIR) graph filters and show how they can be implemented in a distributed manner. To further limit the communication and computational complexity of such a distributed implementation, we also generalize the state-of-the-art distributed graph filters to filters whose weights show a dependency on the nodes sharing information. These so-called edge-variant graph filters yield significant benefits in terms of filter order reduction and can be used for solving specific distributed optimization problems with an extremely fast convergence. Finally, we will overview how graph filters can be used in deep learning applications involving data sets with an irregular structure. Different types of graph filters can be used in the convolution step of graph convolutional networks leading to different trade-offs in performance and complexity. The numerical results presented in this talk illustrate the potential of graph filters in distributed optimization and deep learning.

The last 40 years have seen a dramatic progress in machine learning and statistical methods for speech and language processing like speech recognition, handwriting recognition and machine translation. Many of the key statistical concepts had originally been developed for speech recognition and language translation. Examples of such key concepts are the Bayes decision rule for minimum error rate and sequence-to-sequence processing using approaches like the alignment mechanism based on hidden Markov models and the attention mechanism based on neural networks. Recently the accuracy of speech recognition and machine translation could be improved significantly by the use of artificial neural networks and specific architectures, such as deep feedforward multi-layer perceptrons and recurrent neural networks, attention and transformer architectures. We will discuss these approaches in detail and how they form part of the probabilistic approach.

This course will deal with deep learning for unimodal, multimodal, and multisensorial signal analysis and synthesis. Modalities mainly include audio, video, text, or physiological signals. Methods shown will, however, be applicable to a broad range of further signal types. We will first deal with pre-processing for denoising or dereverberation or package loss concealment. This will be followed by representation learning such as by convolutional neural networks or sequence-to-sequence encoder-decoder architectures as basis for end-to-end learning from raw signals or symbolic representation. Then, we shall discuss modelling for decision making such as by recurrent neural networks with long-short-term memory or gated recurrent units including handling dynamics by connectionist temporal classification. This will also include discussion of the usage of attention on different levels. We will further elaborate on the impact of topologies including multiple targets with shared layers, and how to move towards self-shaping networks in the sense of Automatic Machine Learning. In a last part, we will deal with some practical questions. These include data efficiency, such as by weak supervision with the human in the loop, data augmentation, active and semi-supervised learning, transfer learning, self-learning, or generative adversarial networks. Further, we will have a glance at modelling efficiency such as by squeezing networks. Privacy, trustability, and explainability enhancing solutions will include federated learning, confidence measurement, and diverse means of visualization. The content shown will be accompanied by open-source implementations of according toolkits available on github. Application examples will mainly come from the domains of Affective Computing, and mHealth.

Generative Modeling (GM) refers to building a model of data, p(x), we can sample from, e.g., x is an image. It requires building a distribution of data and latent variables. On the other hand Discriminative Modeling refers to tasks such as regression and classification, which estimate conditional distributions such as p(class|x). Even for prediction, GMs are useful due to: data efficiency and semi-supervised learning, model checking by sampling, and understanding. All GMs represent probability distributions: some allow distribution to be evaluated explicitly, others do not allow distribution to be evaluated but allow sampling. Generative Adversarial Networks (GANs) can learn high-dimensional, complex real data distributions without relying on any assumptions. They can simply generate realistic samples from latent space. This has led to various applications, such as image synthesis, image attribute editing, image translation, domain adaptation and others.

The success of deep-learning hinges on intermediate representations: transformations of the data on which statistical learning is easier. Deep architectures can extract very rich and powerful representations, but it needs huge volumes of data. In this course, we will study the fundamentals of simple representations. Simple representations are interesting because they can be learned in limited data settings. We will also use them to provide didactic cases to understand how to build statistical models from data. The goal of the course is to provide the basic mathematical concepts that underly successful representation extracted in limited data settings.

The past few years have seen a dramatic increase in the performance of recognition systems thanks to the introduction of deep networks for representation learning. However, the mathematical reasons for this success remain elusive. For example, a key issue is that the neural network training problem is nonconvex, hence optimization algorithms are not guaranteed to return a global minima. The first part of this tutorial will overview recent work on the theory of deep learning that aims to understand how to design the network architecture, how to regularize the network weights, and how to guarantee global optimality. The second part of this tutorial will present sufficient conditions to guarantee that local minima are globally optimal and that a local descent strategy can reach a global minima from any initialization. Such conditions apply to problems in matrix factorization, tensor factorization and deep learning. The third part of this tutorial will present an analysis of dropout for matrix factorization, and establish connections
