Title: Quantum Graph Reachability Problem

Abstract: Graph reachability is a fundamental problem in database theory and many other areas of computer science. In this talk, we consider quantum graph reachability problem, which originally arose in verification and analysis of quantum programs and model-checking quantum systems, but may also interest database community. We will discuss the following issues: 1. How we can naturally define a graph structure in the state Hilbert space of a quantum system from its (discrete-time) dynamics? 2. Why the approaches to classical graph reachability problem do not work for quantum reachability problem? 3. Strongly connected component decomposition theorem for quantum graphs. At the end of the talk, a series of open problems will be pointed out, including possible applications to database search in future quantum computers.

Title: Big Data Integration

Abstract: The Big Data era is upon us: data arebeing generated, collected and analyzed at an unprecedented scale, and data-driven decision making is sweeping through all aspects of society. Since the value of data explodes when it can be linked and fused with other data, addressing the big data integration (BDI) challenge is critical to realizing the promise of Big Data. BDI differs from traditional data integration in many dimensions: (i) the number of data sources, even for a single domain, has grown to be in the tens of thousands, (ii) many of the data sources are very dynamic, as a huge amount of newly collected data are continuously made available, (iii) the data sources are extremely heterogeneous in their structure, with considerable variety even for substantially similar entities, and (iv) the data sources are of widely differing qualities, with significant differences in the coverage, accuracy and timeliness of data provided. This talk presents techniques to address these novel challenges faced by big data integration, and identifies a range of open problems for the community.

Title: Hybrid Human-Machine Big Data Integration

Abstract: Data integration cannot be completely addressed by automated processes. We proposed a hybrid human-machine method that harnesses human ability to address this problem. The framework first uses machine algorithms to identify possible matching pairs and then utilizes the crowd to compute actual matching pairs from these candidate pairs. In this talk, I will introduce our two systems on hybrid human-machine big data integration. (1) DIMA: A distributed in-memory system on big-data integration that can use SQL to integrate heterogenous data. DIAM can be used to identify candidate matching pairs in big data integration. (2) CDB: A crowd-powered database system that provides declarative programming interfaces and allows users to utilize an SQL-like language for posing crowdsourced queries. CDB can be used to refine the candidate pairs in big data integration.

Title: Transforming Bell's Inequalities into State Classifiers with Machine Learning

Abstract: Quantum information science has profoundly changed the ways we understand, store, and process information. A major challenge in this field is to look for an efficient means for classifying quantum state. For instance, one may want to determine if a given quantum state is entangled or not. However, the process of a complete characterization of quantum states, known as quantum state tomography, is a resource-consuming operation in general. An attractive proposal would be the use of Bell's inequalities as an entanglement witness, where only partial information of the quantum state is needed. The problem is that entanglement is necessary but not sufficient for violating Bell's inequalities, making it an unreliable state classifier. Here we aim at solving this problem by the methods of machine learning. More precisely, given a family of quantum states, we randomly picked a subset of it to construct a quantum-state classifier, accepting only partial information of each quantum state. Our results indicated that these transformed Bell-type inequalities can perform significantly better than the original Bell's inequalities in classifying entangled states. We further extended our analysis to three-qubit and four-qubit systems, performing classification of quantum states into multiple species. These results demonstrate how the tools in machine learning can be applied to solving problems in quantum information science.

Title: A Separability-Entanglement Classifier via Machine Learning

Abstract: The problem of determining whether a given quantum state is entangled lies at the heart of quantum information processing, which is known to be an NP-hard problem in general. Despite the proposed many methods such as the positive partial transpose (PPT) criterion and the k-symmetric extendibility criterion to tackle this problem in practice, none of them enables a general, effective solution to the problem even for small dimensions. Explicitly, separable states form a high-dimensional convex set, which exhibits a vastly complicated structure. In this work, we build a new separability-entanglement classifier underpinned by machine learning techniques. Our method outperforms the existing methods in generic cases in terms of both speed and accuracy, opening up the avenues to explore quantum entanglement via the machine learning approach.

Title: Machine Learning for Frustrated Classical Spin Models

Abstract: In this talk, we will apply the machine learning method to study classical XY model on frustrated lattices, such as triangle lattice and UnionJack lattice. The low temperature phases of these frustrated models exhibit both U(1) and Z2 chiral symmetry breaking, and therefore they are characterized by two order parameters, and consequently, two successive phase transitions as lowering the temperature. By using classical Monte Carlo to generate a large number of data to feed computer, we use methods such as the principle component analysis (PCA) to analyze these data. We find that the PCA method can distinguish all different phases and locate phase transitions, without prior knowledge of order parameters. Our work offers promise for using machine learning techniques to study sophisticated statistical models, and our results can be further improved by using principle component analysis with kernel tricks and the neural network method.

Title: Gate sequence reuse in randomised benchmarking

Abstract: Quantum computing (applying quantum gates to quantum states) is so hot right now, but how good are your gates? Randomised benchmarking is an experimental technique aimed at estimating the average error in a set of gates. Due to its ease of implementation and propensity to produce favourable numbers, it is now the de facto standard. However, standard practice can lead to the wrong conclusions. Here I will use a simple analogy to convince you that one seemingly innocuous choice (sequence reuse) is not only problematic, but a symptom of a bigger problem. I will also provide a simple fix to this problem.




Dr Shenggang Ying, University of Technology Sydney

Recently he focuses on designing such quantum algorithms without the help of any quantum database or quantum oracle, which are much easier to implement and can manage real-world privacy-preserving tasks in the near future.



Title: Quantum Privacy-Preserving Perceptron

Abstract: With the extensive applications of machine learning, the issue of private or sensitive data in the training examples becomes more and more serious: during the training process, personal information or habits may be disclosed to unexpected persons or organisations, which can cause serious privacy problems or even financial loss. In this paper, we present a quantum privacy-preserving algorithm for machine learning with perceptron. There are mainly two steps to protect original training examples. Firstly when checking the current classifier, quantum tests are employed to detect data user's possible dishonesty. Secondly when updating the current classifier, private random noise is used to protect the original data. The advantages of our algorithm are: (1) it protects training examples better than the known classical methods; (2) it requires no quantum database and thus is easy to implement. Moreover, it can be simply generalized to deal with other machine learning tasks (for instance, association rule mining and decision tree learning) and preserve both parties' privacy.

Title: Contextual Intent Tracking for Personal Assistants

Abstract: A new paradigm of recommendation is emerging in intelligent personal assistants such as Apple's Siri, Google Now, and Microsoft Cortana, which recommends "the right information at the right time" and proactively helps you "get things done". This type of recommendation requires precisely tracking users' contemporaneous intent, i.e., what type of information (e.g., weather, stock prices) users currently intend to know, and what tasks (e.g., playing music, getting taxis) they intend to do. Users' intent is closely related to context, which includes both external environments such as time and location, and users' internal activities that can be sensed by personal assistants. The relationship between context and intent exhibits complicated co-occurring and sequential correlation, and contextual signals are also heterogeneous and sparse, which makes modeling the context-intent relationship a challenging task. To solve the intent tracking problem, we propose the Kalman filter regularized PARAFAC2 (KP2) nowcasting model, which compactly represents the structure and co-movement of context and intent. The KP2 model utilizes collaborative capabilities among users, and learns for each user a personalized dynamic system that enables efficient nowcasting of users' intent. Extensive experiments using real-world data sets from a commercial personal assistant show that the KP2 model significantly outperforms various methods, and provides inspiring implications for deploying large-scale proactive recommendation systems in personal assistants.

Title: Euclidean DBSCAN Revisited: From Static to Dynamic

Abstract: DBSCAN is a highly successful density-based clustering method for multi-dimensional points. Its seminal paper won the Test-of-Time Award at KDD 2014, and it has over 9000 citations at Google Scholar. Although DBSCAN has received extensive applications, its computational hardness was unsolved until the recent work at SIGMOD 2015. This talk focuses on the problem of computing DBSCAN clusters on a set of n points in d-dimensional space from scratch (assuming no existing indexes) under the Euclidean distance. More specifically, we first show the DBSCAN problem is “hard” in three or higher dimensional space. Motivated by this, we propose a relaxed version of the problem called ρ-approximate DBSCAN, which returns the same clusters as DBSCAN, unless the clusters are “unstable”. The ρ-approximate problem is “easy” regardless of the constant dimensionality. This talk further investigate the algorithmic principles for dynamic clustering by DBSCAN. Surprisingly, we prove that the ρ-approximate version suffers from the very same hardness when the dataset is fully dynamic. We also show that this issue goes away as soon as tiny further relaxation is applied, yet still ensuring the same quality of ρ-approximate DBSCAN.

Title: Big Data Meets the Microgrid: Challenges and Opportunities

Abstract: A microgrid is a discrete energy system consisting of distributed energy sources (including demand management, storage, and generation) and loads capable of operating in parallel with, or independently from, the main power grid. It paves a way to effectively integrate various sources of distributed generation, especially Renewable Energy Sources (RES), and meanwhile provides a good solution for supplying power in case of an emergency by having the ability to change between islanded mode and grid-connected mode. On the other hand, control and protection are big challenges in this type of network configuration, which draws our attention to utilize data analytics techniques for enabling smarter control in the microgrid ecosystem. With an extensive range of sensors installed in the microgrid, it has been continuously generating streaming machine-to-machine (M2M) data to support dynamic optimization of power generation, consumption and storage. Microgrids bring significant new challenges and opportunities to data management and data analytics, from data acquisition, data quality control, data compression, data fusion, data disaggregation, data mining, and data prediction. In this talk we will introduce this emerging area to the data management community, with an emphasis on the challenges and some promising research topics on large scale mcirogrid data analytics.
