Extended Essay

Students completing the IB Diploma are required to completd the Extended Essay as part of the Diploma core. You may elect to do your Extended Essay for Computer Science if you wish (subject to supervision capabilities).

Choosing a topic

Recommended

  • Extended essays should begin with “to what extent”. Should be a question rather than just a topic.
  • The best Computer Science EE's are those that specifically compare related technologies/protocols/algorithms against each other in a measured evaluation (this could be search, sort, encryption, compression, path finding, machine learning, ... whatever)

Examples of bad topics:

  • The virus VBS/Love Letter. Why was it so effective in it’s attacks? – Could be ok but needs refinement so emphasis is technical not social.
  • Are hackers really malicious individuals? – Too broad, opinion based, sociological rather than technical.
  • To what extent will quantum computing mean an end to network security? - Too broad, unable to conduct meaningful primary research
  • Which operating system out of Windows or Linux will give a better and more efficient performance? – Define criteria for better and efficient? Under what context? Don’t just take statistics off a website. Conduct primary research as well (install on two identical computers?)

Cautions

  • Artificial Intelligence topics are quite common. Quite a few are done very poorly (lack of genuine technical expertise being displayed). That said there are some very good ones so it can be done – just be cautious.
  • Getting historical is a mistake. A comparison analysis of algorithms etc is really essential.
  • Stay away from the ethics / advantages / disadvantages of social networks etc - this is ITGS not CS
  • Moores law – they get 100s of these each year. Stay away from HISTORY
  • WEBSITES, USERS, HISTORY – predominately ITGS topics not CS.
  • The effects of the technology – these EE belong under ITGS (where as studying the technology itself – this belongs under CS)

Maching learning
Certainly the flavour of the month. Be aware that means the markers will receive lots of them, so yours needs to be good to stand out from the crowd. What could you do? Some aspects of ML you could use to narrow your EE:
Machine Learning

  • Learning methods: Supervised, unsupervised, reinforcement learning
  • Decide on efficacy measure: Spead of decision making, adaptability, innovation, insight
  • Branches of ML: Computational learning theory, Adversarial Machine Learning, Quantum Machine Learning, Predictive Analysis, Robot Learning, Grammar Induction, Meta-Learning
  • Available tools: ai-one, Protege, IBM Watson, TensorFlow, Amazon Web Services, OpenNN, Apache Spark, Caffe, Veles
  • Topics: Machine Learning Algorithms, Computer Vision, Supervised Machine Learning, Unsupervised Machine Learning, Deep Learning, Neural Networks, Reinforcement Learning, Predictive Learning, Bayesian Network, Data Mining

Timeline Expectations

These are the completion expectations I apply to students who wish to do their EE in Computer Science.
Computer Science expectations for Extended Essays

Pre-meeting in early March

  • Proposed focus, question, programming elment.
  • Agreement on what the student needs to do in order to refine the question & proposed program by the next meeting.

Late March meeting

  • Topic and proposed programming element to be approved/locked in this meeting (scope, feasible)
  • First formal reflection to be written following this meeting

Deadline: 28 March 2018

May deadline

  1. Background research finished
    • except where new research is required to explain the programming results (ie: the primary research)
  2. Program finished
    • though data collection could be ongoing - project dependant and requires pre-approval
  3. Need to be able to start writing up results of the primary research (program) and secondary research after this date.

Submit your draft EE and notes as they currently stand.

Deadline: 16 May 2018

June meeting

  • Action plan for the summer to be agreed upon.
  • Second formal meeting to be written as a reflection

Deadline: 20 June 2018

August deadline

  • Full draft which includes results of the programming portion.
  • Formal feedback on full draft to be provided pre-Biarritz

Deadline: 24 August 2018

October deadline

  • Final version submitted

Deadline: 1 October 2018

Post-Biarritz viva voce

  • All done, let's celebrate!

Deadline: 17 October 2018
