Clustering is a fundamental problem in data science, used in myriad of applications. Despite significant research in different fields, clustering remains a major challenge. Most traditional approaches to designing and analyzing clustering algorithms have mainly focused on one shot clustering, where the goal is to design an algorithm to cluster a one-time dataset well. Unfortunately, from a theoretical standpoint, there are major impossibility results for such scenarios; first, in most applications it is not clear what notion of similarity or what objective function to use in order to recover a good clustering for a given dataset; second even in cases where the similarity function and the objectives can be naturally specified, optimally solving the underlying combinatorial clustering problems is typically intractable.
In this talk, I will describe a lifelong transfer clustering approach to address these challenges. Motivated by the fact that in many modern settings, we often need to solve not only one, but many clustering problems arising in a given application domain, we consider algorithms that adaptively learn to cluster. In particular, given a series of clustering instances to be solved from the same domain, we show how to learn a good parameter setting for clustering algorithms that perform well on instances coming from that domain. We provide formal guarantees on the number of typical problem instances that are sufficient to ensure that a clustering algorithm that does well on these typical instances, will also do well on new instances coming from the same domain, as a function of the complexity of the underlying parametrized family of clustering algorithms. We also show a significant benefit of our approach experimentally on datasets such as MNIST, CIFAR, and Omniglot.

There is a high global demand for the learning of English as an additional language. Automatic assessment systems can help meet this need by reducing human assessment effort and enabling learners to independently monitor their progress when/wherever they choose. To properly determine a candidate’s spoken English proficiency the auto-marker should be able to accurately assess the learner’s ability level from spontaneous, prompted, speech. This should be independent of L1 language and audio recording quality which vary considerably making this a challenging task. This talk will look at the application of deep learning to spontaneous spoken English assessment. Examples of tasks that will be discussed include:
These tasks make use of a range of deep-learning techniques including: recurrent sequence models; sequence ensemble distillation (teacher-student training); attention mechanisms; and Siamese networks.

In this talk, I will discuss recent machine learning and AI theory, methods, algorithms and systems which we developed in our lab to understand the basis of health and disease, to catalyze clinical research, to support clinical decisions through individualized medicine, to inform clinical pathways, to better utilize resources & reduce costs and to inform public health.
To do this, we are creating what I call Learning Engines for Healthcare (LEH’s). An LEH is an integrated ecosystem that uses machine learning, AI and operations research to provide clinical insights and healthcare intelligence to all the stakeholders (patients, clinicians, hospitals, administrators). In contrast to an Electronic Health Record, which provides a static, passive, isolated display of information, an LEH provides dynamic, active, holistic & individualized display of information including alerts.
In this talk I will focus on 3 steps in the development of LEH’s:

The past few years have seen intensive research effort and dramatic improvements in neural network-based generative models. Modern generative models can generate large-scale photorealistic images that would have been unthinkable a few short years ago. More recent efforts have demonstrated how we can exploit these generative models for improved classification performance, transfer data from one domain to another, gain a 3D world from single 2D images and even how these models can be used to support reinforcement learning of AI agents.
This lecture will cover modern deep-learning based generative models with an emphasis on breadth. I will present four categories of deep generative models: autoregressive models, normalizing flows, variational autoencoders, and adversarial generative models. My goal is to highlight how the relative strengths and weaknesses of these diverse approaches and to show how neural networks are being leveraged in each of the these modelling paradigms to achieve impressive performance.

Some have argued that the advent of big data and machine learning spells the end of theory, and that big data makes makes scientific method obsolete. If only we let powerful computers to crunch through big data, statistical machine learning algorithms will find patterns where science cannot, they claim. In this course, we will show that, big data, instead of making the scientific method obsolete, makes ever increasing demands on it. We will argue for the importance of causal models In making sense of big data. We will show how causal models can be used to identify (and hence adjust for confounders). We will show how causal models can be learned from data. We will see how the causal lens allows us to peer into black box models produced by machine learning, to explain the predictions they make, and thus provide powerful tools for enhancing the transparency, explainability, and fairness of complex predictive models trained using machine learning. If time permits, we will touch upon additional topics such as causal transportability.

Deep learning has become a major enabling technology for computer vision. By exploiting its multi-level representation and the availability of big data, deep learning has led to dramatic performance improvements for certain tasks. Despite the significant progresses they have made, existing deep learning methods are deterministic and cannot effectively quantify their prediction uncertainty. Uncertainty quantification is not only important to improve the algorithm’s performance but is also essential for my practical applications. Furthermore, existing deep learning methods perform point-based prediction. Point-based prediction not only requires a time-consuming and heuristic training process but also suffers from overfitting and poor adaptation to novel conditions. Through this lecture, I will introduce probabilistic deep learning, where the deep models capture the probabilistic distribution of inputs and outputs, and produce not only a prediction but also its probability distribution. The lecture consists of 4 parts. In part 1, I will review the basic probability calculus and fundamental concepts in machine learning. Part 2 will cover deep probabilistic neural networks and deep Bayesian neural networks. In part 3, I will discuss deep probabilistic graphical models. The lecture will conclude with a discussion of applications of probabilistic deep learning to different computer vision and image processing tasks.

Deep neural networks has been hugely successful in various domains, such as computer vision, speech recognition, and natural language processing. Though powerful, the large number of network weights leads to space and time inefficiencies in both training and storage. Recently, attempts have been made to reduce the model size. They include sparsification using pruning and sparsity regularization, quantization to replace the weights and activations with fewer number of bits, low-rank approximation, distillation and the use of more compact structures. These attempts greatly reduce the network size, and allows possibility of deploying deep models in resource-constrained environments, such as embedded systems, smart phones and other portable devices.

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, such as deep feedforward multi-layer perceptrons and recurrent neural networks (incl. long short-term memory extension). We will discuss these approaches in detail and how they form part of the probabilistic approach.

This course will deal with deep learning algorithms into multimodal and multisensorial signal analysis such as from 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. 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 compensation of dynamics by connectionist temporal classification. This will also include discussion of the usage of attention on different levels. We will also elaborate on the impact of topologies including multiple targets with shared layers and bottlenecks, and how to move towards self-shaping networks in the sense of Automatic Machine Learning. In a last part, we will deal with data efficiency, such as by weak supervision with the human in the loop based on data augmentation, active and semi-supervised learning, transfer learning, or generative adversarial networks. The content shown will be accompanied by open-source implementations of according toolkits available on github. Application examples will come from the domains of Affective Computing, Multimedia Retrieval, and mHealth.

Today’s AI approaches based on deep learning perform perceptual and other tasks exceedingly well. However the methods optimize the solution to each task, without considering the interpretability of the solution by humans. In tasks where human judgment is a necessary component, as in medicine and the courtroom, it is necessary for the decision by the AI system to be accompanied by an explanation. We will describe different types of explainability. Then go over several approaches to explainability in AI, emphasizing probabilistic approaches. We will take the example of forensic comparison and show how a high performance deep learning system and an explainable system can coexist.

This presentation will primarily focus on learning algorithms with reduced iterations or no iterations at all. Some of the algorithms have closed form solutions while some of the algorithms do not adjust the structures once constructed. The main algorithms considered in this talk are randomized neural networks, kernel ridge regression and random forest. These non-iterative methods have attracted attention of researchers due to their high performance in terms of accuracy as well as their ability to train fast due to their non-iterative properties or closed form solutions. For example, the random forest delivers the top classification performance. The presentation will also include the basic methods as well as their state of the art variants. These algorithms will be benchmarked using classification, time series forecasting and visual tracking datasets. Future research directions will also be suggested.

Neural networks & Deep learning and Support vector machines & Kernel methods have been among the most powerful and successful techniques in machine learning and data driven modelling. Initially, in artificial neural networks, the use of one hidden layer feedforward networks was common because of their universal approximation property. However, the existence of many local minima solutions in the training process was encountered as a drawback. Therefore, support vector machines and kernel methods became widely used, relying on solving convex optimization problems in classification and regression. In the meantime, computing power has increased and data have become abundantly available in many applications. As a result, currently one can afford training deep models consisting of (many) more layers and interconnection weights. Examples of successful deep learning models are convolutional neural networks, residual neural networks, stacked autoencoders, deep Boltzmann machines, deep generative models and generative adversarial networks. However, recent works related to understanding generalization, efficient training and adversarial networks, indicate that achieving complementary insights from kernel-based approaches and deep learning will become increasingly important.
In this course we will explain several synergies between neural networks, deep learning, least squares support vector machines and kernel methods. A key role at this point is played by primal and dual model representations and different duality principles. Recent developments on Restricted Kernel Machines will be highlighted, revealing new insights between neural networks, deep learning and kernel methods. In this way the bigger and unifying picture will be obtained and future perspectives will be outlined.
The material is organized into 3 parts:
In Part I a basic introduction is given to support vector machines (SVM) and kernel methods with emphasis on their artificial neural networks (ANN) interpretations. The latter can be understood in view of primal and dual model representations, expressed in terms of the feature map and the kernel function, respectively. Related to least squares support vector machines (LS-SVM) such characterizations exist for supervised and unsupervised learning, including classification, regression, kernel principal component analysis (KPCA), kernel spectral clustering (KSC), kernel canonical correlation analysis (KCCA), and other. Primal and dual representations are also relevant in order to obtain efficient training algorithms, tailored to the nature of the given application (high dimensional input spaces versus large data sizes). Application examples are given e.g. in black-box weather forecasting, pollution modelling, prediction of energy consumption, and community detection in networks.
In Part II we explain how to obtain a so-called restricted kernel machine (RKM) representation for least squares support vector machine related models. By using a principle of conjugate feature duality it is possible to obtain a similar representation as in restricted Boltzmann machines (RBM) (with visible and hidden units), which are used in deep belief networks (DBN) and deep Boltzmann machines (DBM). The principle is explained both for supervised and unsupervised learning. Related to kernel principal component analysis a generative model is obtained within the restricted kernel machine framework. In such a generative model the trained model is able to generate new data examples. The use of tensor-based models is also very natural within this new RKM framework.
In Part III deep restricted kernel machines (Deep RKM) are explained which consist of restricted kernel machines taken in a deep architecture. In these models a distinction is made between depth in a layer sense and depth in a level sense. Links and differences with stacked autoencoders and deep Boltzmann machines are given. The framework enables to conceive both deep feedforward neural networks (DNN) and deep kernel machines, through primal and dual model representations. In this case one has multiple feature maps over the different levels in companion with multiple kernel functions. By fusing the objectives of the different levels (e.g. several KPCA levels followed by an LS-SVM classifier) in the deep architecture, the training process becomes faster and gives improved solutions. Different training algorithms and methods for large data sets will be discussed.
Finally, based on the newly obtained insights, future perspectives and challenges will be outlined.

Neuroscience and artficial intelligence have long benefited from strong mutual interactions. Neuroscience has provided initial models of neural architectures to solve cognitive problems, such as vision, sound or language processing. Conversely, the spectacular development of artificial architectures in the last decade has brought candidates model to analyse the functional architecture of several brain systems. Importantly, leveraging neuroimaging data requires the analysis of large amounts of brain images or signals, making it a canonical example of larg-escale structured signal analysis. In this course, we will review the interactions between neuroscience and AI, then discuss current challenges regarding the interactions of these fields.

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

Big data holds the potential to solve many challenging problems, and one of them is natural language understanding. As an example, big data has enabled the breakthrough in machine translation. However, natural language understanding still faces tremendous challenges. It has been shown that in areas such as question answering and conversation, domain knowledge is indispensable. Thus, how to acquire, represent, and apply domain knowledge for text understanding is of critical importance. In this short course, I will focus on understanding short text, which is crucial to many applications. Short texts do not always observe the syntax of a written language. As a result, traditional natural language processing methods cannot be easily applied. Second, short texts usually do not contain sufficient statistical signals to support many state-of-the-art approaches for text processing such as topic modeling. Third, short texts are usually more ambiguous. I will go over various techniques in knowledge acquisition, representation, and inferencing has been proposed for text understanding, and will describe massive structured and semi-structured data that have been made available in the recent decade that directly or indirectly encode human knowledge, turning the knowledge representation problems into a computational grand challenge with feasible solutions insight.

Complex semantic meaning in natural language is hard to be mined using computational approach. Deep language models learning a hierarchical representation proved to be a powerful tool for natural language processing, text mining and information retrieval. This course will cover the models for word embedding and learning representations of text for information retrieval and text mining. The topic includes an introduction of language models for word embedding. It is followed by a presentation of recent multi-resolution models that represent documents at multiple resolutions in term of abstract levels. More specifically, we first form a mixture of weighted representations across the whole hierarchy of a given word embedding model, so that all resolutions of the hierarchical representation are preserved for the downstream model. In addition we combine all mixture representations from various models as an ensemble representation. Finally, the application for information retrieval and other text mining tasks is presented in the course.

This course aims at exposing the audience an introduction to the fundamental theories and advanced methods on knowledge discovery from complex data with deep learning. It is a well-accepted fact that today we are drown with data. Further typically the data we face are complex data. Complex data refer to the most comprehensive data formats we encounter. By complex data, it is meant that the data may be non-structural, media data such as text, imagery, video, audio, and graphics/animation, and/or that the data may be in the other modalities including time-series data, sequential data, and relational data that violate the i.i.d. assumption such as the social network data, e-commerce data, financial interaction/transaction data, and cyber communication/attack data where the data can be represented as a multi-type node graph involving multiple players, and further that the data may be noisy, meaning that not only the data per se can be noisy, but also the given training labels, if there are any, can also be noisy, such as in the scenario of image annotation or classification where the given training labels can be imperfect (incorrect and/or incomplete). Consequently, complex data represent the most commonly encountered data in our daily life and also in almost all the real-world applications and thus, it is also extremely challenging to develop theories on complex data learning.
The course begins with an extensive introduction to the fundamental concepts and theories of knowledge discovery from complex data, as well as the relevant deep learning theories required for knowledge discovery from complex data; then the course showcases several important applications as case studies in the real-world as examples for knowledge discovery from complex data with deep learning.
The course consists of three an hour and half sessions. The syllabus is as follows:
