The proof relies on an interesting encoding argument. Uniform and preferential attachment trees are among the simplest examples of such dynamically growing networks. The statistical problems we address in this talk regard discovering the past of the network when a present-day snapshot is observed. Such problems are sometimes termed "network archeology". We present a few results that show that, even in gigantic networks, a lot of information is preserved from the very early days.

He graduated in electrical engineering at the Technical University of Budapest in , and received his Ph. His research main interests include the theory of machine learning, combinatorial statistics, inequalities in probability, random graphs and random structures, and information theory. Examples are: aerospace, transportation, medical devices, financial systems. In this talk I will outline my research activity as for model based synthesis and verification of software based control systems and show how the general purpose algorithms and tools developed have been used in specific application domains.

In simulated environments e. In real-world settings, exploration is costly, and a potentially dangerous proposition, as it requires experimenting with actions that have unknown consequences. In this talk, I will present our work towards rigorously reasoning about safety of exploration in reinforcement learning.

I will discuss a model-free approach, where we seek to optimize an unknown reward function subject to unknown constraints. Both reward and constraints are revealed through noisy experiments, and safety requires that no infeasible action is chosen at any point. I will also discuss model-based approaches, where we learn about system dynamics through exploration, yet need to verify safety of the estimated policy.

Our approaches use Bayesian inference over the objective, constraints and dynamics, and -- under some regularity conditions -- are guaranteed to be both safe and complete, i. I will also present recent results harnessing the model uncertainty for improving efficiency of exploration, and show experiments on safely and efficiently tuning cyber-physical systems in a data-driven manner.

He received his Ph. Many Cyber-Physical Systems are indeed control systems: the software part is designed to control the physical part, so that some desired behavior is achieved. Applications of such Cyber-Physical Control Systems are ubiquitous: smart grids, electrical engineering, aerospace, automotive, biology, and so on. Recently, many methodologies have been presented on automatically synthesizing controllers for Cyber-Physical Systems.

In this talk, I will present a selection of such methodologies, mainly focusing on my own contributions. RF-powered computing enables the redesign of personal computing devices in a battery-less manner. While there has been substantial work on the underlying methods for RF-powered computing, practical applications of this technology has largely been limited to scenarios that involve simple tasks.

This talk discusses how RFID technology, typically used to implement object identification and counting, can be exploited to realize a battery-free smart home. In particular, this talk considers the coexistence of several battery-free devices, with different transmission requirements - periodic, event-based, and real-time - and proposes a new approach to dynamically collect information from devices without requiring any a priori knowledge of the environment. As four special cases, the context may be a search query, a slot for an advertisement, a social media user, or an opportunity to show recommendations.

We want to compare many alternative ranking functions that select results in different ways. This research provides a method to use traffic that was exposed to a past ranking function to obtain an unbiased estimate of the utility of a hypothetical new ranking function. The method is a purely offline computation, and relies on assumptions that are quite reasonable. We show further how to design a ranking function that is the best possible, given the same assumptions.

Learning optimal rankings for search results given queries is a special case. Experimental findings on data logged by a real-world e-commerce web site are positive. New research challenges arise in this information space due to the intrinsic decentralized data creation and management, the lack of superimposed schema, and the availability of huge volumes of data covering diverse domains.

In this talk, I will give an overview of my research activities in the areas of graph querying and explanation languages, knowledge discovery from graphs, and social networks. I will also outline some ongoing research activities centered around the marriage between machine learning and knowledge representation and reasoning. Learning in the limit is one of the main computational models of learnability. A learner is modeled by a computational device which inductively generates hypotheses about an input language and stabilizes in the limit on a correct guess.

Contrary to other models of learning, this model allows to decide questions of the following type: Is it the case that some learning constraint or learning strategy is necessary for learning some language class? I will discuss the case of so-called "U-shaped learning", a prominent and as-of-yet not well-understood feature of human learning in many contexts.

The study of the effective or computable content and relative strength of theorems is one of the main areas of recent research in Computable Mathematics and Reverse Mathematics. I will outline a framework in which the following questions can be addressed: Given two theorems, is one stronger than the other or are they equivalent? Is it the case that one theorem is reducible to the other by a computable reduction? Given a problem, what is the complexity of its solutions to computable instances?

I will discuss the case of Hindman's Finite Sums Theorem, which is the subject of a number of long-standing open problems in the area. The focus of this talk is to discuss how the numerical formats of data impacts the energy efficiency of the computation, and how to trade-off accuracy with power savings. Machine Learning and Deep Learning are used as case studies to present the key ideas and the benefits derived by a flexible format to represent numerical data.

One of the reasons for their success is the fact that these frameworks are able to accurately capture the nature of large-scale computation. In particular, compared to the classic distributed algorithms or PRAM models, these frameworks allow for much more local computation.

The fundamental question that arises in this context is though: can we leverage this additional power to obtain even faster parallel algorithms? A prominent example here is the fundamental graph problem of finding maximum matching. It is well known that in the PRAM model one can compute a 2-approximate maximum matching in O log n rounds.

However, the exact complexity of this problem in the MPC framework is still far from understood. Lattanzi et al. These techniques, as well as the approaches developed in the follow up work, seem though to get stuck in a fundamental way at roughly O log n rounds once we enter the near-linear memory regime.

It is thus entirely possible that in this regime, which captures in particular the case of sparse graph computations, the best MPC round complexity matches what one can already get in the PRAM model, without the need to take advantage of the extra local computation power. In this talk, we finally show how to refute that perplexing possibility.

That is, we break the above O log n round complexity bound even in the case of slightly sublinear memory per machine. The first part will explain the main properties of blockchain applications. During the second part, we will show how blockchain properties can have an impact on security and show some examples of past vulnerabilities suffered by blockchain-based systems.

What are good starting points for people who want to try working in this field? The talk will focus on challenges for basic graph problems e. The trend is likely to rely on the use of space based systems in a growing number of services or applications that can be either safety-of-life critical or business and mission-critical.

The various and possible cyber-attacks on space segments, ground stations and its control segments are meanwhile well known and experienced in many cases. We address the Cybersecurity specific aspects of space missions, the specific threats to space mission from cyberspace, and analyze the set of all the possible countermeasures.

Recently OT has been very successfully used for domain adaptation in many applications in computer vision, texture analysis, tomographic reconstruction and clustering. We introduce a new regularizer OT which is tailored to better preserve the class structure. We give the first theoretical guarantees for an OT scheme that respects class structure. We give an accelerated proximal--projection scheme for this formulation with the proximal operator in closed form to give a highly scalable algorithm for computing optimal transport plans.

Our experiments show that the new regularizer preserves class structure better and is more robust compared to previous regularizers. This can be motivated, for instance, by wireless networks in which we combine direct device-to-device communication with communication via the cellular infrastructure.

I will show how to quickly build up a low-diameter, low-degree network of global edges i. In this work, we study a specific aspect of this problem: How to determine familial, relatives relations among a large group of individuals, while keeping genomic DNA data private or almost private. There are several commercial companies that provide such service, albeit in completely non private manner: The individual customers supply their entire genomic DNA information to these companies.

We describe the moderator model, where customers keep their DNA information locally, and a central moderator matches pairs of persons who are likely to be related. These persons then engage in a secure two party computation, which checks more accurately for familial relations, and does not leak any additional information.

The entire protocol leaks only a bounded amount of information to the moderator or to any other party. Despite their differences, all those projects have the same common goal, which is to extract profitable knowledge from very large datasets using cutting-edge data mining and machine learning techniques. I will therefore show the validity of the solutions proposed by measuring their impact on key performance indicators of interest.

However, in these days with the advanced defensive methods that are followed by network administrators classical exfiltration techniques are rendered useless. This talk presents two innovative exfiltration techniques that rely on Covert Channels and seems to be able to circumvent the major network administrators defences.

In this talk, we present an improved guarantee of 6. Finally, we also consider the semi-supervised setting. Given an oracle that returns whether two given points belong to the same cluster in a fixed optimal clustering, we should that few queries are sufficient to recover a clustering that is arbitrarily close to the optimal one.

Does the depth of your pockets impact your protocols? In particular, their financial capacity seems to be irrelevant. In the latest trend to guarantee that secure multi-party computation protocols are fair and not vulnerable to malicious aborts, a slate of protocols has been proposed based on penalty mechanisms.

We look at two well-known penalty mechanisms, and show that the so-called see-saw mechanism Kumaresan et al. Depending on the scheme, fairness is not affordable by everyone which has several policy implications on protocol design. To explicitly capture the above issues, we introduce a new property called financial fairness.

Despite early successes, the rise of adversarial machine learning has called into question the robustness of many such approaches. In adversarial machine learning, an attacker learns how to generate a malicious object in such a way that it gets classified as benign by a target classifier. My talk will discuss adversarial machine learning in the domain of JavaScript exploits. I will review existing classifiers for the detection of JavaScript exploits, and outline techniques to obfuscate exploits automatically so that they no longer get identified.

Our work shows that, in order to achieve JavaScript exploit detectors that are robust to adversarial samples, much still needs to be done. Indeed, combinatorial topology has been identified as a universal framework in which many different models for distributed computing can be expressed, and using combinatorial topology has been shown to be quite useful for analyzing the complexity of problems in these models.

The talk will also present some recent results about the application of combinatorial topology in the framework of distributed network computing. Such a response is usually selected either with a static attack-response mapping or by quantitatively evaluating all the available responses, given a set of pre-defined criteria. In contrast with most existing approaches to intrusion response, the proposed IRS effectively captures the dynamics of both the defended system and the attacker and is able to compose atomic response actions to plan optimal multi-objective long-term response policies to protect the system.

We evaluate the effectiveness of the proposed IRS by showing that long-term response planning always outperforms short-term planning, and we conduct a thorough performance assessment to show that the proposed IRS can be adopted to protect large distributed systems at run-time.

Capturing the rules that govern its control flow helps to understand the boundaries of its behaviour. That is the essence of the research field called process mining. A blockchain can be defined at large as an immutable distributed ledger on which transactions between peers are recorded. Transactions are cryptographically signed and are meant to transfer digital commodities between parties. The validation and publication of transactions is the job of the nodes called miners. Lately, the blockchains have undergone a paradigm shift from mere electronic cash systems to a universal platform endowed with internal programming languages, on top of which decentralised applications can be built.

That has been the turning point enabling the execution of processes on blockchains. This talk revolves around recent advancements in research concerning the execution and mining of processes on the blockchain. The discourse will include a focus on the automated discovery of behavioural specifications from process data, and, in turn, on the extraction of process data from blockchains.

The research field is however still limited when it comes to modelling and learning from videos, to reasoning on objects, parts and scenes and to developing universal representations and memory which fit multiple tasks. I would present my research and interests in the field. On the other hand, in practice, the input is often far from worst case, and has some predictable characteristics. A recent line of work has shown how to use machine learned predictions to circumvent strong lower bounds on competitive ratios in classic online problems such as ski rental and caching.

We study how predictive techniques can be used to break through worst case barriers in online scheduling. The makespan minimization problem with restricted assignments is a classic problem in online scheduling theory. We identify a robust quantity that can be predicted and then used to guide online algorithms to achieve better performance.

Our predictions are compact in size, having dimension linear in the number of machines, and can be learned using standard off the shelf methods. We then give an online algorithm that rounds any fractional assignment into an integral schedule. Specifically, this is achieved by linear programming relaxations in the Sherali-Adams hierarchy. We also provide subexponential time approximation algorithms based on linear programming for Khot's Unique Games problem, which have a qualitatively similar performance to previously known subexponential time algorithms based on spectral methods and on semidefinite programming.

Approaches towards clustering in axis-parallel or arbitrarily oriented affine subspaces differ in how they interpret the overall goal, which is finding clusters in data with high dimensionality. The adjacent image shows a mere two-dimensional space where a number of clusters can be identified.

If the subspaces are not axis-parallel, an infinite number of subspaces is possible. Hence, subspace clustering algorithms utilize some kind of heuristic to remain computationally feasible, at the risk of producing inferior results. For example, the downward-closure property cf. Projected clustering seeks to assign each point to a unique cluster, but clusters may exist in different subspaces.

The general approach is to use a special distance function together with a regular clustering algorithm. For example, the PreDeCon algorithm checks which attributes seem to support a clustering for each point, and adjusts the distance function such that dimensions with low variance are amplified in the distance function. Points are assigned to the medoid closest, considering only the subspace of that medoid in determining the distance.

The algorithm then proceeds as the regular PAM algorithm. If the distance function weights attributes differently, but never with 0 and hence never drops irrelevant attributes , the algorithm is called a "soft"-projected clustering algorithm.

Projection-based clustering is based on a nonlinear projection of high-dimensional data into a two-dimensional space. In the next step, the Delaunay graph [13] between the projected points is calculated, and each vertex between two projected points is weighted with the high-dimensional distance between the corresponding high-dimensional data points.

Thereafter the shortest path between every pair of points is computed using the Dijkstra algorithm. Not all algorithms try to either find a unique cluster assignment for each point or all clusters in all subspaces; many settle for a result in between, where a number of possibly overlapping, but not necessarily exhaustive set of clusters are found. An example is FIRES, which is from its basic approach a subspace clustering algorithm, but uses a heuristic too aggressive to credibly produce all subspace clusters.

This can be beneficial in the health domain where, e. An important question in such data is to compare and correlate patient conditions and therapy results along with combinations of dimensions. The number of dimensions is often very large, consequently one needs to map them to a smaller number of relevant dimensions to be more amenable for expert analysis.

This is because irrelevant, redundant, and conflicting dimensions can negatively affect effectiveness and efficiency of the whole analytic process. Another type of subspaces is considered in Correlation clustering Data Mining. Archiving the history of the blockchain ecosystem allows for simple, secure, and trustless bridges between networks.
