Unless otherwise stated, the course runs on Tuesdays, 9.30-12.00 and 13.00-15.30, in Room 43-2.43
Course material, notes, references, software, manuals, links to external sources such as manuals, etc. are collected in this page and linked below when relevant.
We will work on some or all of the exercises given in the schedule for the course day; unless otherwise stated, you are expected to continue with the remaining exercises as home work. Depending on how difficult they turn out to be, we may or may not go through a solution the following course day.

NB: You are not expected to be able to reproduce the details of the book's formulas for adjusting weights,
but you should understand the overall feed-forward, back-propagation mechanism. We will also look at one or both of two tools for building and training neural nets which you can find at http://www.geocities.com/adotsaha/NNinExcel.html, produced by Angshuman Saha; you should read this page and the explanations provided by the two tools. NB: These tools run as Excel sheets, so they should be easy to run open and test. |
Exercises: Note with exercises about Neural Networks,
question 7.1-7.4; if time 7.5.
Questions 7.5-7.6 recommended as homework. Second and last part of the written assignment. You should send you answer as one pdf or word file by electronic mail to henning@ruc.dk at latest Sunday, November 11. You must give a short presentation to the other students 13-nov-2007 - or before if you are ready for it :). |

QA | 3-jan-2008 10.00-14.00 |
Question-and-answer session
Preparation for the exam |
Please send questions or topics you want explained in advance to your teacher. If no questions or indications of interest have been received by 2-jan-2008 at 12.00, this session is cancelled. | |
X | 10-jan-2008 | EXAM |
Advices and guidelines for the exam There will be a slot of total 30 min's for the exam of each student, including examiner's evaluation. Examination may take about 15-20 min's, and you are expected to start with a presentation of your written assignment, part 2, of perhaps 5 to 7 min's, which will be followed by a discussion. The examiners will most likely also ask a question to part of the course literature which is not directly related to your assignment; questions may also be asked in relation to written assignment, part 1, and possibly other parts of the course curriculum. Those of you who did not give in written assignment part 2 cannot make a presentation, so expect more questions in the entire course curriculum. An advice: The presentation of the assignment needs not be fancy, it's the content that matters. A possible structure could be: Which problem did I approach, how did I approach it, and what did I learn .... Another advice: The report that you gave in for the assignment is not in itself assessed in the exam, so if you you are aware of any weak points, you need not "defend" or "repair" but you can (if you like) take these as points for discussion. If there is any doubt, contact your teacher. Detailed time schedule is found in the exam letter that has been sent to you by email. |
