2. Optimizing databases in the cloud based on performance and cost savings
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : As cloud service providers becomes more prevalent, so does questions related to cost efficiency of hosted resources. Payment models for cloud hosted resources tend to be either subscription based or pay-as-you-go for computing resources, in this case for compound metrics of CPU, Data IO and Log IO. READ MORE

4. Active Learning for Solving Expensive Optimization Problems
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Many practical engineering and computer science problems can be translated into a global otimization problem where the task is to find the best (optimal) vector 𝒙𝒙∗ that gives the smallest possible function value 𝑓𝑓 = 𝑓𝑓(𝒙𝒙∗) for some function 𝑓𝑓() of interest. Often the function 𝑓𝑓() is expensive in the sense that it cannot be easily evaluated computationally or experimentally in terms of time and/or resources required. READ MORE
