Private Learning Implies Online Learning: An Efficient Reduction
Gonen, Alon, Hazan, Elad, Moran, Shay
Differential Private Learning and Online Learning are two well-studied areas in machine learning. While at a first glance these two subjects may seem disparate, recent works gathered a growing amount of evidence which suggests otherwise. For example, Adaptive Data Analysis [15, 14, 24, 19, 3] shares strong similarities with adversarial frameworks studied in online learning, and on the other hand exploits ideas and tools from differential privacy. A more formal relation between private and online learning is manifested by the following fact: Every privately learnable class is online learnable. This implication and variants of it were derived by several recent works [20, 9, 1] (see the related work section for more details). One caveat of the latter results is that they are non-constructive: they show that every privately learnable class has a finite Littlestone dimension. Then, since the Littlestone dimension is known to capture online learnability [26, 5], it follows that privately learnable classes are indeed online learnable. Consequently, the implied online learner is not necessarily efficient, even if the assumed private learner is.
Secure and Private AI Udacity
What's the earliest we can predict cancer survival rates, and what schools do the best job of educating children? You can only answer these questions with very rare access to private and personal data, but access to this personal data requires that you master methods for the principled protection of user privacy. While not all privacy use cases have been solved, the last few years have seen great strides in privacy-preserving technologies. This free course will introduce you to three cutting-edge technologies for privacy-preserving AI: Federated Learning, Differential Privacy, and Encrypted Computation. You will learn how to use the newest privacy-preserving technologies, such as OpenMined's PySyft.

Cascading Non-Stationary Bandits: Online Learning to Rank in the Non-Stationary Cascade Model
Non-stationarity appears in many online applications such as web search and advertising. In this paper, we study the online learning to rank problem in a non-stationary environment where user preferences change abruptly at an unknown moment in time. We consider the problem of identifying the K most attractive items and propose cascading non-stationary bandits, an online learning variant of the cascading model, where a user browses a ranked list from top to bottom and clicks on the first attractive item. We propose two algorithms for solving this non-stationary problem: CascadeDUCB and CascadeSWUCB. We analyze their performance and derive gap-dependent upper bounds on the n-step regret of these algorithms. We also establish a lower bound on the regret for cascading non-stationary bandits and show that both algorithms match the lower bound up to a logarithmic factor. Finally, we evaluate their performance on a real-world web search click dataset.
Reinvention in the age of AI - IoT Agenda
In the economic game of survival of the fittest, reinvention is a constant theme. Where would Samsung be today if it still sold dried fish? For example, Uber is often mentioned as an example of an industry disruptor that displaced jobs for incumbent taxi drivers. However, a recent analysis of Uber's impact on U.S. cities showed that Uber not only increased the number of jobs for drivers by 50% on average, but the wages for Uber drivers were about 10% higher. The same is true for technological progress -- while it does disrupt the way things were done in the past, it also opens the door for new opportunities and skills.
Matrix-Free Preconditioning in Online Learning
Cutkosky, Ashok, Sarlos, Tamas
We provide an online convex optimization algorithm with regret that interpolates between the regret of an algorithm using an optimal preconditioning matrix and one using a diagonal preconditioning matrix. Our regret bound is never worse than that obtained by diagonal preconditioning, and in certain setting even surpasses that of algorithms with full-matrix preconditioning. Importantly, our algorithm runs in the same time and space complexity as online gradient descent. Along the way we incorporate new techniques that mildly streamline and improve logarithmic factors in prior regret analyses. We conclude by benchmarking our algorithm on synthetic data and deep learning tasks.

QuesNet: A Unified Representation for Heterogeneous Test Questions
Yin, Yu, Liu, Qi, Huang, Zhenya, Chen, Enhong, Tong, Wei, Wang, Shijin, Su, Yu
Understanding learning materials (e.g. test questions) is a crucial issue in online learning systems, which can promote many applications in education domain. Unfortunately, many supervised approaches suffer from the problem of scarce human labeled data, whereas abundant unlabeled resources are highly underutilized. To alleviate this problem, an effective solution is to use pre-trained representations for question understanding. However, existing pre-training methods in NLP area are infeasible to learn test question representations due to several domain-specific characteristics in education. First, questions usually comprise of heterogeneous data including content text, images and side information. Second, there exists both basic linguistic information as well as domain logic and knowledge. To this end, in this paper, we propose a novel pre-training method, namely QuesNet, for comprehensively learning question representations. Specifically, we first design a unified framework to aggregate question information with its heterogeneous inputs into a comprehensive vector. Then we propose a two-level hierarchical pre-training algorithm to learn better understanding of test questions in an unsupervised way. Here, a novel holed language model objective is developed to extract low-level linguistic features, and a domain-oriented objective is proposed to learn high-level logic and knowledge. Moreover, we show that QuesNet has good capability of being fine-tuned in many question-based tasks. We conduct extensive experiments on large-scale real-world question data, where the experimental results clearly demonstrate the effectiveness of QuesNet for question understanding as well as its superior applicability.
