Dark Data: Why What You Don’t Know Matters

Group: Section for Information, Data and Analysis (IDA)
Speaker: David J. Hand, Imperial College London
Date: 02 November, 2020
Time: 13:00 - 14:00
Location: https://uofglasgow.zoom.us/j/92128593434?pwd=enhTc2xvKyt5Njd5MDU3K1p0ZkFDdz09

Dark data are data you don’t have. It might be that you want today’s data, but all you have is yesterday’s. It might be that certain types of cases are missing from your sample. It might be that the recorded values are inaccurate – no measuring instrument is perfect. It might be that the process of collecting the data changes those very data themselves. It might be that you have only summary values, like averages, which tell you nothing about extremes. Or it might be data that has been collected and stored but not analysed – perhaps they were collected for regulatory compliance reasons. I outline a taxonomy of fifteen types of dark data, showing just how serious the consequences can be. But then I go further, showing strategies for coping with dark data, and even how to take advantage of it in a strategic application of ignorance.

Adaptive Pointwise-Pairwise Learning-to-Rank for Content-based Recommendation and Period-aware Content-based Attention for Time Series Forecasting

Group: Information Retrieval (IR)
Speaker: Yagmur Gizem Cinar, Laboratoire d’Informatique de Grenoble, Univ. Grenoble Alpes, Grenoble, France
Date: 02 November, 2020
Time: 16:00 - 17:00
Location: https://uofglasgow.zoom.us/j/99150712088?pwd=RVJFVzh1MVFsUFlCcjRrZk54Z2xQQT09

Abstract:  

In this talk, she will present (i) adaptive pointwise-pairwise learning-to-rank for content-based recommendation and (ii) period-aware content-based attention for time series forecasting. 

(i) Ranking is widely used in information retrieval, recommendation and natural language processing applications. When designing search or recommender systems and, especially, “learning to rank” strategies, one typically faces the issue of choosing which one of the “pointwise”, “pairwise” and “listwise” approaches should be adopted. Each approach has its own advantages and drawbacks. They focus on the pointwise and pairwise approaches, and extend the standard pointwise and pairwise paradigms for learning-to-rank in the context of personalized recommendation, by considering these two approaches as two extremes of a continuum of possible strategies. It consists of a surrogate loss, adaptive pointwise-pairwise learning-to-rank loss, that models how to select and combine these two approaches adaptively, depending on the context (query or user, pair of items, etc.)

(ii)  Recurrent neural networks (RNNs) recently received considerable attention for sequence modelling and time series analysis. Many time series contain periods, e.g. seasonal changes in weather time series or electricity usage at day and night time. Here, they first analyze the behaviour of RNNs with an attention mechanism with respect to periods in time series. Period-aware attention mechanism for sequence-to-sequence RNNs is designed to capture periods in time series with or without missing values.

Short Bio: Yagmur Gizem Cinar is a postdoctoral researcher at Laboratoire d’Informatique de Grenoble, Univ. Grenoble Alpes, Grenoble, France. She was a postdoctoral research scientist at Naver Labs Europe, France (2018-2020). She received her PhD on Sequence Prediction with Recurrent Neural Networks in the Context of Time Series and Information Retrieval Search Sessions at Univ. Grenoble Alpes in 2019, and MSc degrees in Artificial Intelligence and Electrical Engineering at KU Leuven in 2015 and 2014, respectively. Her research interests are machine learning, deep sequential learning and multi-modal learning.

A Shameless (Wireless) PLUG: A graphical language for closed monoidal categories

Group: Programming Languages at University of Glasgow (PLUG)
Speaker: Dan Ghica, University of Birmingham/Huawei
Date: 10 November, 2020
Time: 15:00 - 16:00
Location: Online

I am pleased to announce that Dan Ghica of The University of Birmingham & Huawei, shall be giving a talk.

Details to be confirmed.

Location

I will be sending the details through PLUG's mailing list, and the SPLS Zulip instance.

More information about PLUGs mailing list can be found here: http://www.dcs.gla.ac.uk/plug/

As with previous Wireless PLUGs I ask that everyone:

  1. join promptly at the advertised start of the session, and we will begin on the academic hour;
  2. start with their camera's turned-off and microphone's muted; and
  3. in the pursit of transparency, and if you are happy to do so, please ensure you can be identified by your user name.

Questions

Should one wish to ask question's during the talk then please use the chat or 'raise a hand' feature. Should the speaker not see these interrupts, I will actively interrupt. I will confirm on the day if the speaker is okay with audio interrupts by attendees.

During question time, I will moderate the questions so please use the chat and 'raise a hand' feature to get my attenion.

A Shameless (Wireless) PLUG: Temporal Language-Integrated Query

Group: Programming Languages at University of Glasgow (PLUG)
Speaker: Simon Fowler, University of Glasgow
Date: 24 November, 2020
Time: 15:00 - 16:00
Location: Online

I am pleased to announce that our own Simon (Fowler) shall be giving a talk.

Temporal data is data that varies over time. There are two dimensions of temporal data: the first is transaction time, which records how the state of the database changes over time (for example, allowing reconstruction of the database at a given point in time), and the second is valid time, which models how the modelled reality changes over time (for example, promotions or salary increases in an HR system).

Temporal data is everywhere. Despite the inclusion of some temporal features in the SQL:2011 standard, mainstream DBMSes have little to no support for temporal data, and so application developers either have to turn to expensive proprietary solutions or implement temporal functionality themselves in an ad-hoc manner.

In this line of work, we build upon support for *language integrated query*, where queries are written within a host language and compiled to efficient SQL, to implement temporal support via query rewriting.

We introduce core languages for transaction time and valid time queries, and formalise translations into a language without explicit temporal support. Leveraging existing work on query normalisation, we also introduce language-level support for temporal joins, which are absent from the SQL:2011 standard.

Building on the formal development, we implement support for temporal querying in the Links web programming language.

[Work in progress. Joint work with James Cheney.]
