Adversarial Machine Learning: On The Deeper Secrets of Deep Learning

Danilo V. Vargas, Associate Professor
Faculty of Information Science and Electrical Engineering, Kyushu University
Email: vargas@inf.kyushu-u.ac.jp

Abstract

Recent research has found out that Deep Neural Networks (DNN) behave strangely to slight changes in the input. This tutorial will talk about this curious, and yet, still poorly understood behavior. Moreover, it will dig deep into the meaning of this behavior and its links to the understanding of DNNs.

In this tutorial, I will explain the basic concepts underlying adversarial machine learning and briefly review the state-of-the-art with many illustrations and examples. In the latter part of the tutorial, I will demonstrate how attacks are helping to understand the behavior of DNNs as well as show how many defenses proposed are not improving the robustness. There are still many challenges and puzzles left unsolved. I will present some of them as well as delineate a couple of paths to a solution. Lastly, the tutorial will be closed with an open discussion and promotion of cross-community collaborations.

Brain-Inspired Spiking Neural Network Architectures for Deep, Incremental Learning and Knowledge Representation   

Prof. Nikola Kasabov
Director, Knowledge Engineering and Discovery Research Institute, Auckland University of Technology, Auckland, New Zealand
Email: nkasabov@aut.ac.nz              

ABSTRACT

The 2 hour tutorial demonstrates that the third generation of artificial neural networks, the spiking neural networks (SNN) are not only capable of deep, incremental learning of temporal or spatio-temporal data, but also enabling the extraction of knowledge representation from the learned data and tracing the knowledge evolution over time from the incoming data. Similarly to how the brain learns, these SNN models do not need to be restricted in number of layers, neurons in each layer, etc. as they adopt self-organising learning principles of the brain. The tutorial consists of 2 parts:

  1. Algorithms for deep, incremental learning in SNN.
  2. Algorithms for knowledge representation and for tracing the knowledge evolution in SNN over time from incoming data. Representing fuzzy spatio-temporal rules from SNN.
  3. Selected Applications

The material is illustrated on an exemplar SNN architecture NeuCube (free software and open source along with a cloud-based version available from www.kedri.aut.ac.nz/neucube). Case studies are presented of brain and environmental data modelling and knowledge representation using incremental and transfer learning algorithms. These include: predictive modelling of EEG and fMRI data measuring cognitive processes and response to treatment; AD prediction; understanding depression; predicting environmental hazards and extreme events.

It is also demonstrated that brain-inspired SNN architectures, such as the NeuCube, allow for  knowledge transfer between humans and machines through building brain-inspired Brain-Computer Interfaces (BI-BCI). These are used to understand human-to-human knowledge transfer through hyper-scanning and also to create brain-like neuro-rehabilitation robots. This opens the way to build a new type of AI systems – the open and transparent  AI.

This tutorial will first introduce the main randomization-based learning paradigms with closed-form solutions such as the randomization-based feedforward neural networks, randomization based recurrent neural networks and kernel ridge regression. The popular instantiation of the feedforward type called random vector functional link neural network (RVFL) originated in early 1990s. Other feedforward methods are random weight neural networks (RWNN), extreme learning machines (ELM), etc. Reservoir computing methods such as echo state networks (ESN) and liquid state machines (LSM) are randomized recurrent networks. Another paradigm is based on kernel trick such as the kernel ridge regressionwhich includes randomization for scaling to large training data. The tutorial will also consider computational complexity with increasing scale of the classification/forecasting problems. Another randomization-based paradigm is the random forest which exhibits highly competitive performances.The tutorial will also present extensive benchmarking studies using classification and forecasting datasets.

Abstract

This tutorial addresses the advances in deep Bayesian learning for sequence data which are ubiquitous in speech, music, text,

image, video, web, communication and networking applications. Spatial and temporal contents are analyzed and represented to fulfill a variety of tasks ranging from classification, synthesis, generation, segmentation, dialogue, search, recommendation, summarization, answering, captioning, mining, translation, adaptation to name a few. Traditionally, “deep learning” is taken to be a learning process where the inference or optimization is based on the real-valued deterministic model. The “latent semantic structure” in words, sentences, images, actions, documents or videos learned from data may not be well expressed or correctly optimized in mathematical logic or computer programs. The “distribution function” in discrete or continuous latent variable model for spatial and temporal sequences may not be properly decomposed or estimated. This tutorial addresses the fundamentals of statistical models and neural networks, and focus on a series of advanced Bayesian models and deep models including recurrent neural network, sequence-to-sequence model, variational auto-encoder (VAE), attention mechanism, memory-augmented neural network, skip neural network, temporal difference VAE, stochastic neural network, stochastic temporal convolutional network, predictive state neural network, and policy neural network. Enhancing the prior/posterior representation is addressed. We present how these models are connected and why they work for a variety of applications on symbolic and complex patterns in sequence data. The variational inference and sampling method are formulated to tackle the optimization for complicated models. The embeddings, clustering or co-clustering of words, sentences or objects are merged with linguistic and semantic constraints. A series of case studies, tasks and applications are presented to tackle different issues in deep Bayesian learning and understanding. At last, we will point out a number of directions and outlooks for future studies. This tutorial serves the objectives to introduce novices to major topics within deep Bayesian learning, motivate and explain a topic of emerging importance for natural language understanding, and present a novel synthesis combining distinct lines of machine learning work.

Evolution of Neural Networks

Email: risto@cs.utexas.edu

 Abstract

Evolution of artificial neural networks has recently emerged as a powerful technique in two areas. First, while the standard value-function based reinforcement learning works well when the environment is fully observable, neuroevolution makes it possible to disambiguate hidden state through memory. Such memory makes new applications possible in areas such as robotic control, game playing, and artificial life. Second, deep learning performance depends crucially on the network architecture and hyperparameters. While many such architectures are too complex to be optimized by hand, neuroevolution can be used to do so automatically. Such evolutionary AutoML can be used to achieve good deep learning performance even with limited resources, or state=of-the art performance with more effort. It is also possible to optimize other aspects of the architecture, like its size, speed, or fit with hardware. In this tutorial, I will review (1) neuroevolution methods that evolve fixed-topology networks, network topologies, and network construction processes, (2) methods for neural architecture search and evolutionary AutoML, and (3) applications of these techniques in control, robotics, artificial life, games, image processing, and language.

Experience Replay for Deep Reinforcement Learning
A Comprehensive Review

Abstract

Reinforcement learning is expected to play an important role in our AI and machine learning era, this is evident by latest major advances, particularly in games. This is due to its flexibility and arguably minimum designer intervention especially when the feature extraction process is left to a robust model such as a deep neural network. Although deep learning alleviated the long-standing burden of manual feature design, another important issue remains to be tackled, that is the experience-hungry nature of RL models which is mainly due to bootstrapping and exploration. One important technique that will play a centre stage role in tackling this issue is experience replay. Naturally, it allows us to capitalise on the already gained experience and to shorten the time needed to train an RL agent. The frequency and depth of the replay can vary significantly and currently a unifying view and a clear understanding of the issues related to off-policy and on-policy replay is generally lacking. For example, on the far end of the spectrum, extensive experience-replay, although should conceivably help reduce the data-intensity of the training period, when done naively, put significant constrains on the practicality of the model and requires both extra time and space that can grow significantly; relegating the method impractical. On the other hand, in its optimal form, whether it is a target re-evaluation or a re-update, when importance sampling ratio uses bootstrapping, the methods computational requirements matches other model based RL methods for planning. In this tutorial we will be tackling the issues and techniques related to the theory and application of deep reinforcement learning and experience replay, and how and when these techniques can be applied effectively to produce a robust model. In addition, we will promote a unified view of experience replay that involves replaying and re-evaluation of the target updates. What is more, we will show that the generalised intensive experience replay method can be used to derive several important algorithms as special cases of other methods including n-steps true online TD and LSTD. This surprising but important view can help immensely the neuro-dynamic/RL community to move this concept further forward and will benefit both the researchers and practitioners in their quest for a better and more practical RL methods and models.

Description

Deep reinforcement learning combined with experience replay allows us to capitalise on the gained experience; capping the model appetite for new experience. Experience replay can be performed in several ways some of which may or may not be suitable for the problem in hand. For example, intensive experience replay, if performed optimally, could shorten the learning cycle of an RL agent and allow it to be taken away from the virtual arena such as games/simulation to the physical/mechanical arena such as robotics. The type of intensive training required for RL models, which can be afforded by a virtual agent, may not be tolerated, or may at least not be desired, for a physical agent. Of course, one way to move to the mechanical world is by utilising model-free policy gradient (search) methods that are based on simulation and then migrate/map the model to the physical world. However, constructing a simulation for the physical world is a tedious process that requires extra time and calibration making it impractical to the type of pervasive RL models that we hope to achieve. In both cases, whether it is a policy gradient or value-function with policy iteration, experience replay plays and important role to make them more practical. For example, for policy gradient methods adopting a softmax policy is preferable over the ε-greedy policy as it can approach asymptotically a deterministic policy after some exploration, while ε-greedy will always have a fixed percentage of exploratory actions regardless of the maturity of the policy being developed/improved.

The tutorial is timely and novel in its treatment and packaging of the topic. It will lay the necessary foundation for a unified overview of the subject. Which will allow other researcher to take it to the next level and will allow the subject area to take off on solid and unified grounds.

It turns out that extensive experience replay can be used as a generalised model from which several n-steps modern reinforcement learning techniques can be deduced, offering an easy way to unify several popular reinforcement learning methods and giving rise to several new more.

In this tutorial I will be giving a step by step detailed overview of the framework that allows us to safely deploy replay methods.
The tutorial will review all major advances of RL replay algorithms and will categorise them into: occasional replay, regular replay, and intensive regular replay.

Bellman equations are the fundamental of individual RL updates, however all the n-steps aggregate methods that have driven the latest breakthrough of RL need different treatment.

The unified view through experience replay offer a new theoretical framework to study the inner traits/properties of those techniques. For example, convergence of several new RL algorithms can be proven by proving the convergence of the unified replay algorithm and then projecting each algorithm as a special case of the general method.

• To contrast traditional replay with the more recent re-evaluation that has been termed as replay

Target audience and session organisation:

The target audience are researchers and practitioners in the growing reinforcement learning community who are seeking a better understanding of the issues surrounding combining experience replay, deep learning and off-policy learning in their quest for a more practical methods and models.

The tutorial will take 2 hours to be completed and will provide code that can be easily run on Octave or MATLAB.

The two-hour tutorial will be delivered into two integrated sections, the first will cover the theory and the second will cover the application. The presenters will alternate between each other on both the theoretical part and the application part. Two applications will be covered one is the game of packman and the other is a hacked mini robot that will learn to navigate in small 2x1m easy to assemble arena. The robot is a cheap affordable robot, such as Lego, that is equipped with a Raspberry PI module and camera. It will use vision and deep learning combined with experience replay to learn to perform a homing task. The audience will be provided with the Octave/MATLAB code to experience first-hand with the algorithms and see how they are developed form the inside. The code is general enough to be reused for other RL problems. For remote access audiences the code will be shared on Git, so they will be able to experiments with the model directly and a web camera will be mounted on top of the small robot arena to broadcast how the robot will gradually learn to navigate towards it home using vision to learn an optimal path and using infra-red sensors for obstacle avoidance behaviour. For those attending the tutorial they can SSH to the controlling laptop, to which the intensive processing is off-boarded, in order to try and change the Octave code that is driving the robot and see its effect. If a VPN can be setup, then the same the remote audiences can be provided with the same experience.

 Abstract

Data stream mining has gained a lot of attention in recent years as an exciting researc

h topic. However, there is still a gap between the pure research proposals and the practical applications to real world machine learning problems. In this tutorial we are going to introduce attendees to data stream mining procedures and examples of big data stream mining applications. Besides the theory we will also present examples using the \skmultiflow framework, a novel open source Python framework.

 Abstract

Deep Neural Networks (DNNs) are a fundamental tool in the modern

development of Machine Learning. Beyond the merits of properly designed training strategies, a great part of DNNs success is undoubtedly due to the inherent properties of their layered architectures, i.e., to the introduced architectural biases. In this tutorial, we analyze how far we can go by relying almost exclusively on these architectural biases. In particular, we explore recent classes of DNN models wherein the majority of connections are randomized or more generally fixed according to some specific heuristic, leading to the development of Fast and Deep Neural Network (FDNN) models. Examples of such systems consist of multi-layered neural network architectures where the connections to the hidden layer(s) are left untrained after initialization. Limiting the training algorithms to operate on a reduced set of weights implies a number of intriguing features. Among them, the extreme efficiency of the resulting learning processes is undoubtedly a striking advantage with respect to fully trained architectures. Besides, despite the involved simplifications, randomized neural systems possess remarkable properties both in practice, achieving state-of-the-art results in multiple domains, and theoretically, allowing to analyze intrinsic properties of neural architectures (e.g. before training of the hidden layers’ connections). In recent years, the study of randomized neural networks has been extended towards deep architectures, opening new research directions to the design of effective yet extremely efficient deep learning models in vectorial as well as in more complex data domains.

This tutorial will cover all the major aspects regarding the design and analysis of Fast and Deep Neural Networks, and some of the key results with respect to their approximation capabilities. In particular, the tutorial will first introduce the fundamentals of randomized neural models in the context of feedforward networks (i.e., Random Vector Functional Link and equivalent models), convolutional filters, and recurrent systems (i.e., Reservoir Computing networks). Then, it will focus specifically on recent results in the domain of deep randomized systems, and their application to structured domains (trees, graphs).
