Model Selection by Algorithm Validation

INTRODUCTORY/ADVANCED

Summary
One of the central challenges in machine learning today relates to the high parameter complexity of models and their relation to a large amount of heterogeneous, noisy data. What is the relevant information in the data to select a model / hypothesis from a hypothesis class? Machine learning research has answered this question to a scientifically satisfactory degree in supervised learning, i.e., classification and regression. Without teacher provided guidance, however, model selection and validation still appears to be a magic engineering art mostly dominated by heuristics fundamental ML algorithms The course willl cover traditional model selection methods like AIC, BIC, but also the stability method and a novel approach based on information theory. The resulting selection score, called posterior agreement criterion, requires hypotheses to agree on two different instances drawn from the same data source. Such a robustness criterion captures the spirit of cross-validation and ensures that hypotheses of models are selected according to the signal in the data and are not significantly affected by noise.

Syllabus
Algorithms and Gibbs distributions, Maximum Entropy method, AIC, BIC, stability selection,
Information Theoretic Model Validation, algorithms as time evolving posterior distributions; examples in approximate sorting, aproximate spanning trees,pipeline tuning in biomedical applications.

Deep Learning for Computer Aided Detection/Diagnosis in Radiology and Pathology

INTERMEDIATE

Summary
Medical imaging is getting more important in modern medicine including radiology, pathology, surgery, neuroscience, etc. In case of radiology, there are several shortcomings in case of typical diagnostic radiology, due to the qualitative reading of a human observer. In addition, the rapid development of recent medical imaging equipment which produce a tremendous amount of image data makes the typical medical image reading nearly impractical. Recently, deep learning shows better accuracy for detection and classification in computer vision, which could be rapidly applied to medical imaging areas. I'll introduce methodology of data science including machine learning, and deep learning, and deep learning based applications in computer vision, computer aided diagnosis in radiology and pathology. In addition, I'll suggest some practical considerations on application of these technology to clinical workflow including efficient labeling technology, interpretability and visualization (No blackbox), uncertainty (Data level, Decision level), reproducibility of deep learning, novelty in supervised learning, one-shot or multi-shot learning due to Imbalanced data set or rare disease, deep survival, and physics induced machine learning.

A Methodical and Cost-effective Approach to Optimization/Generalization of Deep Learning Networks

INTRODUCTORY

Summary
This course will start with the introduction of two basic machine learning subsystems: Feature Engineering (e.g. CNN for Image/Speech Feature Extraction) and Label Engineering, e.g. Multi-layer Perceptron (MLP). The great success of DNN in broad applications of deep learning networks hinges upon the rich nonlinear space embedded in their nonlinear hidden (neuron) layers. However, we face two major challenges: (1) the curse of depth and (2) the ad hoc nature of deep learning. Fortunately, many solutions have been proposed to effectively overcome the 'vanishing gradient' problem due to the curse of depth. In particular, we shall elaborate (a) cross-entropy (with amplified gradients) effective to surrogate the 0-1 loss; (b) the merit of ReLu-neurons and (c) the vital roles of bagging, mini-batch, and dropout.
It is widely recognized that the ad hoc nature of deep learning renders its success at the mercy of trial- and-errors. To combat this problem, we advocate a methodic and cost-effective learning paradigm (MINDnet) to train multi-layer networks. In particular, MINDnet elegantly circumvents the curse of depth by harnessing a new notion of omni-present supervision, i.e. teachers hidden within a sort of 'Trojan-horse' traveling along with the forward-propagating signals from the input to hidden layers. Therefore, one can directly harvest teacher’s information at any hidden-layer in the MLP, i.e. , no- propagation (NP) will be required. This will lead to a new and slender 'inheritance layer' to summarize (inherit) all the discriminant information embedded in the previous layer. Moreover, by augmenting the inheritance layer with additional randomized nodes and applying again back-propagation (BP) learning, the discriminant power of the network can be further enhanced. Finally, we have compared MINDnet with several popular learning models on real-world datasets, including CIFAR images, MNIST, mHealth, HAR, Yale, Olivetti, Essex datsets. Our preliminary simulation seems to suggest some superiority by MINDnet. For example, for the CIFAR-10 dataset, 97.9%+/-0.16% (MINDnet) > 97.4% (CutNet) > 96.0% (DenseNet) > 93.6% (ResNet).

Syllabus
Session 1:
Introduction of two basic machine learning subsystems:
- Feature Engineering: CNN for Image/Speech Feature Extraction
- Label Engineering: multi-layer deep learning networks
Introduce supplementary (SVM-based) subsystems for validation and prediction and highlight their
vital roles in optimization and generalization.
Introduce an effective surrogate function (to surrogate the 0-1 loss) in the training phase:
- How/why cross-entropy offers amplified gradients.

Introduce network friendly training metrics:
• equivalent optimization metrics: LSE (Gauss), FDR (Fisher) and Mutual Information (Shannon).

Session 2:
Derive Back-propagation (BP) Algorithm for
- back-propagation of 1st-order (gradient) and 2nd-order (Hessian) functions
Discuss effective remedies for tackling the vanishing gradient problem in deep networks:
- ReLu-neuron
- bagging, minim-batch, and dropout
Introduce MINDnet learning paradigm:
- Why the acronym MIND: Monotonically INcreasing Discriminant (MIND).
- A simple solution to overcome the Curse of Depth: No-propagation (NP) learning algorithm
o How to harness the teacher information “hidden” in the hidden layer?
- How to use a small number of nodes (inheritance layer) to fully summarize (inherit) all the
useful information embedded in the entire previous layer?
- To highlight the vital role of BP/NP hybrid learning.
Session 3:
Elaborate the detailed procedure to successively construct MINDnets with gradually growing depth:

• (vertical expansion)= full Inheritance with a small number of nodes
• (horizontal expansion)= Inheritance Theorem + random nodes

Demonstrate that the prediction accuracy indeed improves as the MINDnet grows deeper:
• Via a Synthetic dataset, we shall conduct an extensive comparative study of various machine
learning tools in the literature.
- compare MINDnet with other existing networks based real-world datasets such as CIFAR,
MNIST, Yale, Olivetti, Essex, mHealth, HAR, etc.

More than Words can Say: Machine and Deep Learning for Speaker, Language, and Emotion Recognition from Speech

INTRODUCTORY/INTERMEDIATE

Summary
Speech conveys many types of information to the listener. Beyond just the words, the speech signal provides information about what language is being spoken, who is speaking, the emotional state of the speaker, and the acoustic environment in which the speech is occurring. Such extra-word information can be useful for many areas such as secure access, device personalization, audio searching, and medical interactions. Powerful machine learning techniques, including statistical, geometric, and neural pattern recognition, have been successfully applied over several decades to successfully and effectively build systems for automatically recognizing these types of characteristics from challenging, real-world speech recordings. In this tutorial we will introduce the audience to the fundamentals behind speaker, language, and emotion recognition, going from the science behind speech production to the machine learning building blocks underpinning modern recognition systems. We will describe the details of implementing these recognition systems covering the critical role of data in the training and testing of systems. Important areas of domain adaptation, channel compensation, diarization, and effective evaluation design and interpretation will also be covered.

Deep Learning and Kernel Machines

INTRODUCTORY/INTERMEDIATE

Summary
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, stacked autoencoders, deep Boltzmann machines, deep generative models and generative adversarial networks. 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. In this way the bigger picture will be revealed for neural networks, deep learning and kernel machines, and future perspectives will be outlined.

Syllabus
The material is organized into 3 parts:
- Part I Neural networks, support vector machines and kernel methods - Part II Restricted Boltzmann machines, kernel machines and deep learning - Part III Deep restricted kernel machines and future perspectives 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.
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.

Summary
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
