  1. 6. On Systematically Exploring the State Space for Events with SFCs

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Younis Akel; Gianmarco Iachella; [2023-08-07]
    Keywords : Autonomous driving systems; scenario-based testing; space-filling curve SFC ; characteristic stripe patterns CSP ; permutations; state-space; areas of interest AOI ;

    Abstract : In the process of developing autonomous driving systems (AD systems), ensuring safety remains a constant and continuous priority. Scenario-based testing is a popular approach to guarantee the safety of AD systems, which however meets challenges in terms of diversity and efficiency of generation, as well as evaluating existing test case datasets in terms of their coverage of the different variations of a particular maneuver.

  3. 7. Comparing the Locality Preservation of Z-order Curves and Hilbert Curves

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Alex Nordin; Adam Telles; [2023-08-03]
    Keywords : space-filling curve; software engineering; software testing;

    Abstract : Developing and testing software in the automotive industry and in the research of autonomous vehicles requires the costly querying of multidimensional data recorded from such a vehicle’s various sensors. Through encoding such data using space filling curves, faster queries could be achieved by reducing multiple dimensions into a singular dimension, while exploiting the patterns that emerge in the one-dimensional representation to still get accurate search results.

  4. 8. Systematically Analyzing Synthetic Automotive Data to support Space Filling Curves-based Maneuver Detection

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Alexandre Rancati-Palmer; Christopher Axt; [2023-08-03]
    Keywords : Morton; Carla; autonomous driving; edge case;

    Abstract : Context: In autonomous driving system development, the identification of maneuvers within large datasets is progressively becoming more complex, primarily due to the inherent complexity arising from the multidimensional nature of the data describing these maneuvers. In this context, algorithms based on Space-Filling Curves can be an effective way to index datasets by creating a single-dimensional representation of the maneuvers. READ MORE

  5. 9. Credit Card Fraud Detection by Nearest Neighbor Algorithms

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Ramin Maghsood; [2023-04-13]
    Keywords : Fraud; Bank Fraud; Credit Card Fraud; Fraud Detection; Nearest Neighbor Algorithms;

    Abstract : As the usage of internet banking and online purchases have increased dramatically in today’s world, the risk of fraudulent activities and the number of fraud cases are increasing day by day. The most frequent type of bank fraud in recent years is credit card fraud which leads to huge financial losses on a global level. READ MORE

  6. 10. An Attempt at Pricing Zero-Coupon Bonds under the Vasicek Model with a Mean Reverting Stochastic Volatility Factor

    University essay from KTH/Matematik (Avd.)

    Author : Benjamin Neander; Victor Mattson; [2023]
    Keywords : Zero-coupon bond; Vasicek model; Two-factor interest rate model; Stochastic volatility.; Nollkupongobligation; Vasicek model; Räntemodell med två faktorer; Stokastisk volatilitet.;

    Abstract : Empirical evidence indicates that the volatility in asset prices is not constant, but varies over time. However, many simple models for asset pricing rest on an assumption of constancy. READ MORE
