1. 21. Prediction of the gain in classification performance from combining multiple imaging modalities

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Roman Denkin; [2023]
   Nyckelord :;

   Sammanfattning : In this work, we investigate the relationship between different image modalities and classification performance, aiming to predict the potential gain in classification accuracy when combining multiple modalities. We analyze mathematical and statistical measures and develop novel reconstruction measures (RMSE and RSSIM) to assess information distribution between different image modalities. LÄS MER

3. 22. Efficient Traffic Monitoring in IoT Networks for Attack Detection at the Edge

   Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Engla Jansson; [2023]
   Nyckelord :;

   Sammanfattning : The Internet of Things has rapidly expanded over the years, and with this comes significant security risks, with attacks increasing at an alarming rate. A way to detect attacks in the network is by having each device send traffic monitoring information to an edge device that can investigate if any devices have been exploited. LÄS MER

4. 23. Neural Networks for Predictive Maintenance on Highly Imbalanced Industrial Data

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Oscar Montilla Tabares; [2023]
   Nyckelord :Class Imbalance; Cost Sensitivity; Cost-Sensitive Learning; Focal Loss; Binary Classification; Machine Learning; Deep Learning;

   Sammanfattning : Preventive maintenance plays a vital role in optimizing industrial operations. However, detecting equipment needing such maintenance using available data can be particularly challenging due to the class imbalance prevalent in real-world applications. LÄS MER

5. 24. A Machine Learning Approach to Skin Cancer Delineation on Photoacoustic Imaging

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

   Författare :Alice Fracchia; [2023]
   Nyckelord :Skin cancer; carcinoma; photoacoustic imaging; ultrasound imaging; machine learning; dimensionality reduction; sandpiles algorithm; active contour; multilayer perception MLP ; convolutional neural networks CNN ; autoencoder; Physics and Astronomy;

   Sammanfattning : Skin cancer is a growing public health concern due to its prevalence among the population. Current clinical procedures require high invasiveness and multiple surgeries, which are responsible for patient discomfort and high medical expenses. LÄS MER

7. 25. An Empirical Investigation of The Effect of Proxy Response and The Merits of Its Remedial Measures

   Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Charles Edward Okon; Randi Kalanika Assalaarachchi; [2023]
   Nyckelord :missing data; proxy response; missingness mechanism; error-in-variable; logistic regression; Monte-Carlo simulation; missing at random; complete case analysis; proxy substitution; multiple imputation; inverse probability treatment weighting;

   Sammanfattning : In the event of missing data, substitution of data from proxy sources are usually considered a very useful alternative when available to avoid the problem of missingness. Nonetheless, research has also shown that this approach often induces “response bias”. LÄS MER
