1. 1. Ordering Classifier Chains using filter model feature selection techniques

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

   Författare :Robin Gustafsson; [2017]
   Nyckelord :multi-label classification; classifier chain; label dependence;

   Sammanfattning : Context: Multi-label classification concerns classification with multi-dimensional output. The Classifier Chain breaks the multi-label problem into multiple binary classification problems, chaining the classifiers to exploit dependencies between labels. Consequently, its performance is influenced by the chain's order. LÄS MER

3. 2. Robust Image Hash Spoofing

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Författare :Azadeh Amir Asgari; [2016]
   Nyckelord :Robust hash function; Hamming distance; Block mean value; Spoofing attack;

   Sammanfattning : With the intensively increasing of digital media new challenges has been created for authentication and protection of digital intellectual property. A hash function extracts certain features of a multimedia object e.g. an image and maps it to a fixed string of bits. LÄS MER

4. 3. Working with emotions : Recommending subjective labels to music tracks using machine learning

   Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

   Författare :Johan Brodin; [2016]
   Nyckelord :machine learning music;

   Sammanfattning : Curated music collection is a growing field as a result of the freedom and supply that streaming music services like Spotify provide us with. To be able to categorize music tracks based on subjective core values in a scalable manner, this thesis has explored if recommending such labels are possible through machine learning. LÄS MER

5. 4. Visualization of live search

   Master-uppsats, Interaktiva och kognitiva system; Tekniska högskolan

   Författare :Olof Nilsson; [2013]
   Nyckelord :search technology; search engine; information retrieval; live search; query completion; facet; recall; precision; machine learning; document classification; linear classifier; document categorization; document clustering; multi-label classification; labelling; hamming loss; f-score; visualization; information visualization; distance-similarity metaphor; spatialized display; visual information-seeking mantra; user interface; spatialization; document processing;

   Sammanfattning : The classical search engine result page is used for many interactions with search results. While these are effective at communicating relevance, they do not present the context well. LÄS MER
