To continue with my ‘Life as a STOR-i MRes Student’Ìý blogging thread, I have decided to reflect on my previous term (Lent term). This provides me with an opportunity to review the work and activities that I have been involved with between Christmas and Easter 2020. To find out more about life as an MRes student before Christmas, please read my previous post from this thread.

Upon returning from the Christmas break, I was reunited with my colleagues and friends at the STOR-i annual conference (see post). This was a great opportunity to network with key researchers from Statistics, Operational Research and Industry.

Lent term focussed on independent work with a view to give us an insight into life as a PhD student. This involved completing two research projects working with an academic in the field. I worked on

  • Slot Scheduling in Air Transportation with Professor Konstantinos Zografos (see my blog post here)
  • Missing Data with Dr Robin Mitra
These projects provided a great opportunity to work with an expert in their field as well as carry out independent research.Ìý

Another enjoyable part of Lent Term was the problem solving days. This involves a company visiting STOR-i with an industrial problem that may lend itself to either statistics and/or OR, then we work in teams with an aim to provide guidance on a solution. The three problem solving days were:

  • Tesco
    Machine Learning Predictions and Optimisation: Fuel PricingÌýÌý
  • BBC
    Temporal clustering
  • Electricity North West
    Assessing the Plausibility of Data
Masterclass with Prof. Brendan Murphy
Masterclass with Prof. Laura Albert

During Lent term we also had masterclass’ which involved external academics presenting work in their research area. This was another opportunity to network as well as learn about important areas in statistics and OR. The three masterclass’ were:

  • Model-based Clustering and Classification with Professor Brendan Murphy, University College DublinÌý
    (See the blog post I wrote on thisÌýhere)
  • Public Sector OR with Professor Laura Albert, University of Wisconsin Madison
    (See my relevant blog postÌýhere)
  • Bayesian Optimisation with Professor Peter Frazier, Cornell UniversityÌý
    (This was done virtually due to the coronavirus outbreak, many thanks to Peter for making this work)Ìý

Unfortunately the final masterclass (Ranking and Selection for Simulation Optimisation with Professor Barry Nelson from Northwestern University) was cancelled due to the outbreak of the COVID-19 pandemic. This world-wide emergency meant that Lent term came to an abrupt and premature end as we, like many others, were asked to work from home. This meant that many activities and deadlines were postponed. However, working from home has provided me with an opportunity to demonstrate a different style of learning. STOR-i have supported us in working from home by transferring much of our contact and planned events online.

Lent term also involved many social aspects as well. The ¶¶Òõ̽̽App Netball Team won their first (and only) match of the season. We had a term jam-packed with birthdays among the MRes, so there was plenty of celebration! I also went to the ¶¶Òõ̽̽App Undergraduate Conference where many of my friends in undergraduate degrees presented their work.

Whilst Lent term ended in the strangest of circumstances, I appreciate the new working from home skills I have acquired and I feel very grateful for the online platform in which we have been able to continue as close to normal as possible. I thoroughly enjoyed Lent Term and I feel more equipped than ever to continue on my academic journey into a PhD.

Life as a STOR-i MRes Student: Michaelmas Term /stor-i-student-sites/eleanor-darcy/2020/01/14/life-as-a-stor-i-mres-student-michaelmas-term/?utm_source=rss&utm_medium=rss&utm_campaign=life-as-a-stor-i-mres-student-michaelmas-term /stor-i-student-sites/eleanor-darcy/2020/01/14/life-as-a-stor-i-mres-student-michaelmas-term/#comments Tue, 14 Jan 2020 15:46:27 +0000 http://www.lancaster.ac.uk/stor-i-student-sites/eleanor-darcy/?p=278

Introducing my ‘Life as a STOR-i MRes Student’Ìý blogging thread, starting with an overview of Michaelmas term. I decided to complete a blogging thread on my MRes year because it will provide me with an opportunity to reflect on my time as a student at STOR-i as well inform others about the course. I started the STOR-i MRes programme in October 2019, I have already learnt many new skills and topics and thoroughly enjoyed myself during the term.Ìý

In the first week of term, we started with an introductory day to meet some of the staff and students, as well as to learn what STOR-i is all about and what the programme entails. This was followed by a two-day excursion to the Lake District; this was a great opportunity to build relationships with my peers as well as staff and other students. The Away Day included many team-building activities, from designing a team logo and printing it onto a t-shirt to canoeing across Lake Windermere in an orienteering challenge. By the time we came back to Lancaster to start the term properly, we had really got to know each other and were able to support each other through the rest of the term.

STOR-i Away Day 2019

The first half of Michaelmas term consisted of four modules to introduce us to the basic knowledge required for the rest of the year. This included Inference and Modelling, Stochastic Simulation, Deterministic Optimisation and Probability and Stochastic Processes. Within each topic, we had lectures, weekly exercises and workshops to assist with our understanding. Alongside these modules, we attended lectures regarding training for research and industry.

In the second half of term, we completed contemporary topic sprints on a weekly basis. This involved attending a lecture on a Monday morning to gain an overview of the topic and our task, then we would research the topic in teams for 4 days and present it back to an expert in the field later in the week. This was a great way to build on our teamwork, research and presentation skills. The topics were

  • Statistical Leaning for Decision lead by Professor David Leslie,
  • Modelling Paradigms for Complex and Novel Data forms lead by Professor Idris Eckley,
  • Computational Statistics lead by Professor Paul Fearnhead,
  • Optimising under Uncertainty lead by Professor Adam Letchford.

Following the sprints, we chose one topic to explore further and write a report on our findings. I chose Optimisation under Uncertainty and wrote my report on the Stochastic Knapsack Problem with Random Weights. This is an optimisation problem where we have a set of items with different, unknown weights but known reward. We want to choose a set of items to go in the knapsack (which has some maximum capacity) so that the total reward of the knapsack is maximised. Whilst writing this report, I read a lot of the relevant literature and broadened my knowledge on the topic as a whole.

Outside of my studies, I attended many of the events that STOR-i hosted, including a cheese and wine evening as well as the STOR-i Christmas Meal. This allowed me to meet more students and relax outside of studying. Additionally, I started playing netball for ¶¶Òõ̽̽App Graduate College, this has been a great way to meet other postgraduate students from different disciplines. I have thoroughly enjoyed the MRes programme so far and look forward to seeing what the Lent term brings.

Whilst Michaelmas term was busy and challenging, I have thoroughly enjoyed every moment in learning new topics and making new friends.
