Cluster KL-UCB: Optimism for the Best, Pessimism for the Rest
(2022-06-28)The project presents an allocation strategy for the stochastic multi armed bandit when considering instances with a clustered structure. Using the architecture of the KL-UCB policy as a source of inspiration, an algorithm ... -
Convolutional neural networks for semantic segmentation of FIB-SEM volumetric image data
(2020-11-26)Focused ion beam scanning electron microscopy (FIB-SEM) is a well-established microscopy technique for 3D imaging of porous materials. We investigate three porous samples of ethyl cellulose microporous films made from ... -
Credit Card Fraud Detection by Nearest Neighbor Algorithms
(2023-04-13)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 ... -
Curve fitting with confidence for preclinical dose-response data
(2015-02-17)Abstract. In the preclinical stage of pharmaceutical drug development, when investigating the medicinal properties of a new compound, there are two important questions to address. The first question is simply whether the ... -
Decision Making Under Uncertainty: A Robust Optimization
(2014-10-02) -
Decision Policies for Early Stage Clinical Trials with Multiple Endpoints
(2022-11-11)Before a drug can be prescribed to patients, it must be shown to be safe and effective for a certain indication in a controlled clinical trial (known as Phase III). Such studies are costly to run and expose patients to ... -
Delayed-acceptance approximate Bayesian computation Markov chain Monte Carlo: faster simulation using a surrogate model
(2020-01-09)The thesis introduces an innovative way of decreasing the computational cost of approximate Bayesian computation (ABC) simulations when implemented via Markov chain Monte Carlo (MCMC). Bayesian inference has enjoyed ... -
Design and analysis of pre-clinical experiments using a method combining multiple comparisons and modeling techniques for dose-response studies
(2021-04-20)Abstract. Identifying and estimating the dose-response relationship between a compound and a pharmacological endpoint of interest is one of the most important and difficult goals in the preclinical stage of pharmaceutical ... -
Do viscous flows slip?
(2023-12-21)In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis ... -
Effective quasiparallelogram laws on elliptic curves over number fields
(2021-05-21)We introduce the classical theory of heights on projective space and prove explicit quasiparallelogram laws for the ordinary height and the naive height on elliptic curves over number fields with shortWeierstrass equations. ... -
Evidence based training in cross-country skiing: Predicting the force generated by the skier
(2019-12-11)Evidence based training has been around for for while, where data is collected and pre-defined measures are used to evaluate the training session. Skisens AB are presenting new methods to evaluate a session which can be ... -
Exploring a proxy to the CDS-Bond basis
(2013-06-20)This thesis investigates the behaviour of the CDS-bond basis dur- ing and after the 2008 nancial crisis. It is found that the basis plunges deep into negative territory and that the theory of a zero CDS-bond basis is ... -
FEASIBILITY ANALYSIS AND EFFICIENT ROUTING FOR A PARTIALLY AUTOMATED DELIVERY SYSTEM WITHIN CHALMERS CAMPUS
(2021-06-21)Abstract The use of autonomous driving robot transportation technology to solve the last mile delivery problem is a research hot spot in today’s logistics industry. This thesis aims to analyze the feasibility of applying ... -

Group Invariant Convolutional Boltzmann Machines
(2020-12-04)We investigate group invariance in unsupervised learning in the context of certain generative networks based on Boltzmann machines. Specifically, we introduce a generalization of restricted Boltzmann machines which is ... -
Incentives Schemes Under New Regulations
(2015-06-23)Due to the nancial crisis of 2007, regulatory authorities engaged in a fundamental reconsideration of how they approach nancial regulation and supervision. Therefore, that nancial crisis caused the need of a signi ... -
Incentives Schemes Under New Regulations

Investigation of portfolio strategies by means of simulation
(2022-07-01)Portfolio insurance strategies are constructed to limit an investors loss but still reward them when the market goes up. In this thesis we compare two portfolio insurance strategies, Constant proportion portfolio insurance ... -
Joint segmentation of multiple features with application to analysis of epilepsy and music.
(2015-04-29)Multivariate data is segmented into parts, called segments, with common characteristics. The segments are assumed to have an under- lying model structure. It is of interest to see whether the character- istic changes ... -
Knowing a Thousand Formulas Is Not The Same as Knowing Mathematics
(2021-09-07)This research is about how students at different levels of mathematical studies view, understand and study mathematics. The research is based on two theories on mathematical understanding, James Hiebert and Patricia ...
