1. 11. Hybrid Extended Isolation Forest : Anomaly Detection for Bird Alarm

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

   Author : Viktor Holmér; [2019]
   Keywords : ;

   Abstract : The Isolation Forest algorithm is a random forest based anomaly detection algorithm utilizing isolation to determine anomality of data. The Hybrid Isolation Forest and Extended Isolation Forest algorithms were independently developed to overcome two separate issues with the Isolation Forest algorithm. READ MORE

5. 14. Obtaining Entropy via Coarsening: Microscopic Restrictions on Constitutive Equations

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Veronica Wallängen; [2012]
   Keywords : ;

   Abstract : Entropi och temperatur presenteras som fältvärden definierade i termer av lokala medelvärden av atomistiska storheter i rumtiden, och därmed tydliggörs ett icke-traditionellt samband mellan makroskopisk termodynamik och mikroskopisk fysik, utan sannolikhetsfördelningar och medelvärden över ensembler. Genom att analysera beskrivningar av ett termomekaniskt system på olika skalor visas hur termodynamikens andra lag måste begränsa konstitutiva ekvationer snarare än processer och hur detta är relaterat till begreppet reproducerbarhet samt hela existensen av en makroskopisk teori.
