1. 1. Online Sample Selection for Resource Constrained Networked Systems

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Philip Sjösvärd; Samuel Miksits; [2022]
   Nyckelord :Online learning; Sample Selection; Real-time Learning; Random Forest; Reservoir Sampling; Relevance and Redundancy; Binned Distribution; Autoregressive Model; Change Detection; Model Re-computation;

   Sammanfattning : As more devices with different service requirements become connected to networked systems, such as Internet of Things (IoT) devices, maintaining quality of service becomes increasingly difficult. Large data sets can be obtained ahead of time in networks to train prediction models offline, however, resulting in high computational costs. LÄS MER

3. 2. Online Learning with Sample Selection

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Cong Gao; [2021]
   Nyckelord :data-driven engineering; online learning; sample selection; model recomputation; datadriven teknik; online-lärande; dataurval; omberäkning av modeller;

   Sammanfattning : In data-driven network and systems engineering, we often train models offline using measurement data collected from networks. Offline learning achieves good results but has drawbacks. For example, model training incurs a high computational cost and the training process takes a long time. LÄS MER

4. 3. Statistical Approach for the Design of Refresh-Free eDRAM with Retention Timing Constraint

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Arturo Prieto; [2019]
   Nyckelord :Memory; eDRAM; DRAM; SRAM; IC; Refresh; Statistics; Importance Sampling; Monte Carlo; Technology and Engineering;

   Sammanfattning : In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. LÄS MER

5. 4. Non-periodic sampling schemes for control applications

   Uppsats för yrkesexamina på avancerad nivå, Signaler och System

   Författare :Tommy Norgren; Jonathan Styrud; [2010]
   Nyckelord :Non-periodic sampling; discrete PID-control; self-triggered; event-triggered; periodic sampling; anti-stick algorithm; adaptive thresholds; boliden plant; iggesund papermill;

   Sammanfattning : In recent years, research in the field of automation has been advancing quickly in the direction of wireless networks of sensors and actuators. This development has introduced a need to reduce the amount of communication. A number of different alternative schemes have been proposed. LÄS MER

7. 5. Efficient Reconstruction of Two-Periodic Nonuniformly Sampled Signals Applicable to Time-Interleaved ADCs

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Kameswaran Vengattaramane; [2006]
   Nyckelord :Nonuniform Sampling; Reconstruction; Time-varying FIR filter design; Two-channel time-interleaved ADC; Aperture delay mismatch compensation;

   Sammanfattning : Nonuniform sampling occurs in many practical applications either intentionally or unintentionally. This thesis deals with the reconstruction of two-periodic nonuniform signals which is of great importance in two-channel time-interleaved analog-to-digital converters. LÄS MER
