InfoLab fika meeting
Monday 19 Nov
: Scale-free networks well done
Location: 19120, Time: 15:00-16:00

Every Monday we meet in room 120, House 19 to discuss various topics related to the analysis of human-generated information. This time we will discuss the paper:

Scale-free networks well done (https://arxiv.org/abs/1811.02071)

Participants are expected to read the paper in advance. This is also part of the reading course on network science (if you are a PhD student and want credits, more info here:  http://www.it.uu.se/research/group/infolab/netsciphd/netscireadings2018 ). Each meeting starts at 15:00 (please have coffee/tea ready: they can be made in the local kitchen, and espresso can be bought at the lab) and ends at 16:00. The meetings are informal, open and no registration is needed, but if you tell us in advance there are higher chances to get some cookies or cakes. A list of topics is maintained at <http://www.it.uu.se/research/group/infolab/fika>.

SysCon Seminar
22 November
Lennart Ljung, Linköping University: Data Science: From System Identification to (Deep) Learning and Big Data
Location: ITC 2347, Time: 13:15


Welcome to a seminar by

Prof. Lennart Ljung (homepage)
Linköping University

Abstract:
Data science is a topic of great interest which has reached considerable current attention. It includes central research areas such as machine learning, deep learning and "big data”. Despite the extensive nomenclature and wide application areas associated with data science, it is stressed in this presentation that there are only a few central concepts. The use of data science to build mathematical models of dynamic systems - System Identification - is a useful template to illustrate and explain the basic concepts.

DoCS seminar
22 November
Marc Brockschmidt, Microsoft Research Cambridge: Learning from Programs with Graphs
Location: 1113, Time: 15:15

Learning from large corpora of source code ("Big Code") has seen increasing interest over the past few years. A first wave of work has focused on leveraging off-the-shelf methods from other machine learning fields such as natural language processing. While these techniques have succeeded in showing the feasibility of learning from code, and led to some initial practical solutions, they often forego explicit use of known program semantics. In a range of recent work, we have tried to solve this issue by integrating deep learning techniques with program analysis methods in graphs. Graphs are a convenient, general formalism to model entities and their relationships, and are seeing increasing interest from machine learning researchers as well. In this talk, I present two applications of graph-based learning to understanding and generating programs and discuss a range of future work building on the success of this work.

SysCon Seminar
29 November
Dr. Manon Kok: Magnetic Field SLAM
Location: 2244, Time: 13:15

In this talk I will discuss our recent work on scalable magnetic field SLAM in 3D using Gaussian process maps. We use local anomalies in the magnetic field as a source of position information. These anomalies are for instance due to the presence of ferromagnetic material in the structure of buildings and in objects such as furniture. We build local magnetic field maps using three-dimensional hexagonal block tiling. To make our approach computationally tractable we use reduced-rank Gaussian process regression in combination with a Rao–Blackwellised particle filter. We show that it is possible to obtain accurate position and orientation estimates using measurements from a smartphone, and that our approach provides a scalable magnetic field SLAM algorithm in terms of both computational complexity and in terms of map storage.

DoCS/CSD seminar
30 November
Pierre Flener: Solving Combinatorial Problems without Knowing How to Solve Them
Location: ICT 1111, Time: 14:15-15:00

Solving technologies for combinatorial problems abound: mixed-integer programming (MIP), Boolean satisfiability (SAT), satisfiability modulo theories (SMT), constraint programming (CP), local search, etc, and hybrids. No technology dominates the others or shares a modelling language with them. Unbeknownst to many, it has become possible to model the constraints (and objective function) of a combinatorial problem upon learning a single fully declarative high-level modelling language and, upon experiments with solvers of different technologies, to choose a winning technology and solver, without knowing (in depth) how the solvers work.
I present one such language, MiniZinc, to the toolchain of which my research group contributes. I show how the high-level MiniZinc abstractions of common combinatorial structures enable very readable short models of complex problems. These abstractions are directly reasoned upon by CP and SMT solvers, sometimes with great effect, but translated for MIP solvers into linear (in)equalities over integer variables, and for SAT solvers into clauses over Boolean variables. This allows MIP and SAT modellers to reuse well-known encodings systematically rather than tediously or erroneously rediscovering them.
For most managers, engineers, and scientists, the time to achieve a particular solution speed or quality is drastically reduced by such model-once-solve-everywhere toolchains.
