  Choo, Feng-Xuan (University of Waterloo, 2018-05-17)

  Building large-scale brain models is one method used by theoretical neuroscientists to understand the way the human brain functions. Researchers typically use either a bottom-up approach, which focuses on the detailed ...

• Optimization Methods for Semi-Supervised Learning 

  Cheung, Edward (University of Waterloo, 2018-05-17)

  The goal of this thesis is to provide efficient optimization algorithms for some semi-supervised learning (SSL) tasks in machine learning. For many machine learning tasks, training a classifier requires a large amount of ...

• Deep Context Resolution 

  Chen, Junnan (University of Waterloo, 2018-05-17)

  Conversations depend on information from the context. To go beyond one-round conversation, a chatbot must resolve contextual information such as: 1) co-reference resolution, 2) ellipsis resolution, and 3) conjunctive ...

• RAMP: RDMA Migration Platform 

  Memon, Babar Naveed (University of Waterloo, 2018-05-16)

  Remote Direct Memory Access (RDMA) can be used to implement a shared storage abstraction or a shared-nothing abstraction for distributed applications. We argue that the shared storage abstraction is overkill for loosely ...

• An Experimental Analysis of Multi-Perspective Convolutional Neural Networks 

  Tu, Zhucheng (University of Waterloo, 2018-05-16)

  Modelling the similarity of sentence pairs is an important problem in natural language processing and information retrieval, with applications in tasks such as paraphrase identification and answer selection in question ...

• Detecting Feature-Interaction Hotspots in Automotive Software using Relational Algebra 

  Muscedere, Bryan James (University of Waterloo, 2018-05-14)

  Modern software projects are programmed by multiple teams, consist of millions of lines of code, and are split into separate components that, during runtime, may not be contained in the same process. Due to these complexities, ...

• Effective Use of SSDs in Database Systems 

  Ghodsnia, Pedram (University of Waterloo, 2018-05-07)

  With the advent of solid state drives (SSDs), the storage industry has experienced a revolutionary improvement in I/O performance. Compared to traditional hard disk drives (HDDs), SSDs benefit from shorter I/O latency, ...

• Exploring New Forms of Random Projections for Prediction and Dimensionality Reduction in Big-Data Regimes 

  Karimi, Amir-Hossein (University of Waterloo, 2018-05-01)

  The story of this work is dimensionality reduction. Dimensionality reduction is a method that takes as input a point-set P of n points in R^d where d is typically large and attempts to find a lower-dimensional representation ...

• Contact-sensing Input Device Manipulation and Recall 

  Elkin, Lisa (University of Waterloo, 2018-04-30)

  We study a cuboid tangible pen-like input device similar to Vogel and Casiez’s Conte. A conductive 3D-printed Conte device enables touch sensing on a capacitive display, and orientation data from an enclosed inertial ...

• Using Automata Theory to Solve Problems in Additive Number Theory 

  Rajasekaran, Aayush (University of Waterloo, 2018-04-30)

  Additive number theory is the study of the additive properties of integers. Perhaps the best-known theorem is Lagrange’s result that every natural number is the sum of four squares. We study numbers whose base-k representations ...

• On the Utility of Adding An Abstract Domain and Attribute Paths to SQL 

  Ma, Weicong (University of Waterloo, 2018-04-30)

  Albeit its popularity today, RDBMS and the relational model still have many limitations. For example, one needs to pay premature attention to naming issues in the schema designing phase; and the syntax for conjunctive ...

• Space Efficient Data Structures and Algorithms in the Word-RAM Model 

  El-Zein, Hicham (University of Waterloo, 2018-04-30)

  In modern computation the volume of data-sets has increased dramatically. Since the majority of these data-sets are stored in internal memory, reducing their storage requirement is an important research topic. One way ...

• Web Data Integration for Non-Expert Users 

  El-Roby, Ahmed (University of Waterloo, 2018-04-26)

  oday, there is an abundance of structured data available on the web in the form of RDF graphs and relational (i.e., tabular) data. This data comes from heterogeneous sources, and realizing its full value requires integrating ...

• Complexity of Left-Ideal, Suffix-Closed and Suffix-Free Regular Languages 

  Brzozowski, Janusz; Sinnamon, Corwin (Springer, 2017-03-06)

  A language L over an alphabet Σ is suffix-convex if, for any words x,y,z∈Σ∗, whenever z and xyz are in L, then so is yz. Suffix-convex languages include three special cases: left-ideal, suffix-closed, and suffix-free ...
