  1. 21. Machine learning multicriteria optimization in radiation therapy treatment planning

    University essay from KTH/Matematisk statistik

    Author : Tianfang Zhang; [2019]
    Keywords : Radiation therapy; automated planning; machine learning; multicriteria optimization; dose mimicking; dose--volume criteria; Gaussian mixture model; expectation--maximization; exponential tilting; Strålterapi; automatisk planering; maskininlärning; flermålsoptimering; dosåterskapande; dos--volym-kriterier; gaussisk blandningsmodell; förväntning--maximering; exponentiell lutning;

    Abstract : In radiation therapy treatment planning, recent works have used machine learning based on historically delivered plans to automate the process of producing clinically acceptable plans. Compared to traditional approaches such as repeated weighted-sum optimization or multicriteria optimization (MCO), automated planning methods have, in general, the benefits of low computational times and minimal user interaction, but on the other hand lack the flexibility associated with general-purpose frameworks such as MCO.

  3. 22. Explainable AI - Visualization of Neuron Functionality in Recurrent Neural Networks for Text Prediction

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : John Dahlberg; [2019]
    Keywords : Explainability; Visualization; Recurrent Neural Networks; Neuron Functionality; Text Prediction; Förklaringsbarhet; Visualisering; Rekurrenta Neurala Nätverk; Neu- ronfunktionalitet; Textprediktering;

    Abstract : Artificial Neural Networks are successfully solving a wide range of problems with impressive performance. Nevertheless, often very little or nothing is understood in the workings behind these black-box solutions as they are hard to interpret, let alone to explain. READ MORE

  4. 23. Förekomst och angreppsgrad av gråmögel och ”purple spot of asparagus” i skånsk sparrisproduktion

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Lotten Lundgren; [2018]
    Keywords : sparris; Asparagus officinalis; gråmögel; Botrytis cinerea; Stemphylium vesicarium; Stemphylium botryosum; integrerat växtskydd;

    Abstract : Svensk sparrisodling växer, men produktiviteten, mätt som skörden i ton per hektar, är lägre än i närliggande produktionsländer. Medelskörden i Sverige var 1,6 ton per hektar år 2016, medan Tysklands preliminära medelskörd var 5,5 ton/ha år 2017. READ MORE

  5. 24. A Future in Sustainable Development : Backcasting the SDGs

    University essay from KTH/Miljöstrategisk analys (fms)

    Author : Mikael Angelstam; [2017]
    Keywords : 2030 Agenda; Sustainable Development Goals; Sustainable Development; Backcasting; Futures studies; Agenda 2030; Globala hållbarhetsmålen; Globala målen; Hållbar utveckling; Backcasting; Framtidsstudier;

    Abstract : In 2015 the 17 Sustainable Development Goals were adopted by 193 member states of the United Nations. The SDGs are highly ambitious and their underlying processes are interconnected by causal relationships. Work towards fulfilling them therefore requires considering how solutions for one goal will impacts others. READ MORE

  6. 25. Testing the Cretaceous Diversity of Ichthyosaurs and Their Extinction Hypotheses Using a Quantitative Approach

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Naz Acikkol; [2015]
    Keywords : diversity; ichthyosaurs; extinction; belemnites; ammonites; prey; predator; rock record; sampling bias; Cretaceous; mångfald; utdöende; fisködlor; belemniter; rovdjur; byte;

    Abstract : As portrayed in Before the Dinosaur: the Historical Significance of the Fossil Marine Reptiles, ichthyosaurs, as other Mesozoic marine amniotes, have been unfairly overshadowed by dinosaurs in both popular culture and the field of vertebrate palaeontology. Yet by the effort of dedicated researchers, work on these fish-like marine reptiles had never died out, and in fact a second wave of interest emerged in the late 20th century. READ MORE
