Generating Exams and Formative Feedback

Franked, Lennart January 2018 (has links)
Creating an exam that ensures an even coverage over all the Intended Learning Outcomes and at the same time ensures that to pass, the student should have passed all the Intended Learning Outcomes can be a difficult task. After an exam have been graded, formative feedback should be given to the students, especially in those cases where they did not pass the exam. This can be a time consuming process, and because of this, it is not always possible to give as good feedback as one would otherwise like. In this project an exam tool was created, for assisting in creating exams and give individual formative feedback to the students after an exam. By storing all the questions in a database, where each question is connected to an Intended Learning Outcome, along with writing the questions in a standardised format, with regards to point representations, grading rubrics and references it becomes possible to automatically generate exams. Generated individual feedback is created by combining the information in the question together with the students result. The feedback provides motivation of given grade, which topics a student should read up on, along with recommended reading instructions. In those cases a student got a full mark, it is also possible to provide further study instructions, this can be anything from recommended articles and book chapter, to courses. Differential privacy have been used to anonymize the grade distribution to make it possible to show the students how the exam went, without risk exposing what grade a certain student got. The exam tool created achieves all of these goals, however there are still much room for improvement. The anonymisation function needs further development, since differential privacy is not suitable for small datasets. The usability of the interface and feedback reports needs more work. However in its current state it is fully functional and have been used in numerous courses.

Discrete Small Sample Asymptotics

Kathman, Steven Jay Jr. 05 January 2000 (has links)
Random variables defined on the natural numbers may often be approximated by Poisson variables. Just as normal approximations may be improved by saddlepoint methods, Poisson approximations may be substantially improved by tilting, expansion, and other related methods. This work will develop and examine the use of these methods, as well as present examples where such methods may be needed. / Ph. D.

Generating Functions : Powerful Tools for Recurrence Relations. Hermite Polynomials Generating Function

Rydén, Christoffer January 2023 (has links)
In this report we will plunge down in the fascinating world of the generating functions. Generating functions showcase the "power of power series", giving more depth to the word "power" in power series. We start off small to get a good understanding of the generating function and what it does. Also, off course, explaining why it works and why we can do some of the things we do with them. We will see alot of examples throughout the text that helps the reader to grasp the mathematical object that is the generating function. We will look at several kinds of generating functions, the main focus when we establish our understanding of these will be the "ordinary power series" generating function ("ops") that we discuss before moving on to the "exponential generating function" ("egf"). During our discussion on ops we will see a "first time in literature" derivation of the generating function for a recurrence relation regarding "branched coverings". After finishing the discussion regarding egf we move on the Hermite polynomials and show how we derive their generating function. Which is a generating function that generates functions. Lastly we will have a quick look at the "moment generating function".

Integrace Sociálních sítí / Integrace Sociálních sítí

Mašíček, Viktor January 2010 (has links)
Social networks are the current phenomenon, and their integration begins to gain importance. Basic idea is to pair identical pieces of information stored in various social networks and to detect inconsistencies between them. The most important data that need to be integrated are user profi les and lists of contacts. In our work, we propose the integration of both the pro files and lists of contacts, and even groups of users that could be created in social networks. Implementation is not part of the work. However the proposal suggests the creation of Main social network in form of a web application, that brokers the integration to end users. From the perspective of users it is bene cial to display data from all social networks in one place and automate detection of di erences. User's data could be used for commercial purposes, of course, within legal limits. From this perspective, the biggest contribution of Main social network is a social graph. It consists of various social graphs of social networks. Additionally it would contain information about membership of users in social networks. The proposal consists of three main parts: main processes of the Main social network, its data model and means of gathering information from different networks. The design of data model was partially inspired by existing...

XSLT Benchmarking / XSLT Benchmarking

Mašíček, Viktor January 2012 (has links)
The main goal of this work was to create an XSLT Benchmark, to compare available XSLT processors. At first, we determined main criteria of XSLT processors (price, correctness, speed, memory usage, support, OS and UX), which we discussed. Next, we summarized existing XSLT processors, described individual types of processors (program, library and browser) and measured criteria price, support, OS} and UX. We had to create appropriate test environment to measure criteria correctness, speed and memory usage. Created program XSLT Benchmarking is one of the main benefits of this work. The program also includes tests. We created tests based on 5787 downloaded XSLT files. Tests were created based on the analysis of these files. Firstly, we researched common features of XSLT files (used elements, used XSLT versions, output format etc.). Secondly, we researched focuses of their usages. Next big benefit of this work is a summary of results of tests from different views. We discussed other criteria and features of tested processors. Finally, we summarized possible extensions of our program and also of our analysis.

Generating Signal by Trellis and Study on its Recovery

Tsai, Wen-Jung 31 August 2006 (has links)
Signal model and observation model are commonly used to describe a dynamic system model in system identification or estimation such as Kalman filtering. The signal model is usually described by a linear dynamical equation driven by generating noise. The observation model is composed of a linear transformed signal and an additive white Gaussian noise. In this thesis, we set the generating noise to be a white binary sequence. This discrete generating noise makes the generating signal to be discrete. In contrast, the conventional generating signal is continuous. Discrete signal is simpler than the continuous signal. However, there still are too many states for this discrete signal. Therefore, defining the states and reducing the number of states are important in our work. In this thesis, we apply the tree structure to define the states. The number of states is reduced by focusing on the most probable working states. Afterwards, we apply two methods to recover the white sequence using the observation data. One is the Viterbi method; the other is Extended Kalman filter. Both methods are based upon the concept of signal states. Finally, we compare the error rates with the signal generated by continues phase modulation method.
