Tikhonov and Sobolev regularisers compared to user-based KNN collaborative filtering

Collaborative filtering is used to predict the preference or rating of a user for a certain item. Collaborative filtering is based on the notion that similar users rate similarly. A lot of research is done on how to improve this algorithm, mostly with deep learning. A less investigated field for recommender systems is graph signal processing....

Vehicle Choice and System Performance: The Influence of a Dynamic Pricing User-Based Relocation Strategy: Stated Choice and Field Experiments in a Free-floating E-moped Sharing System

Free-floating moped sharing systems are becoming more and more popular and provide new ways to travel inside urban areas. The vehicles offer the flexibility of one-way transportation, though the downside is that it creates a spatiotemporal imbalance of the vehicle distribution within the system. The operators of such systems are challenged to...

User-Based Rebalancing by Dynamic Pricing in Free-Floating Vehicle Sharing: A Case Study with Multiple Living Labs

Dynamic pricing can be used for better fleet distribution in free-floating vehicle sharing (FFVS), and thus increase utilization and revenue for the provider by reducing the supply-demand asymmetry. Supply-demand asymmetry refers to the existence of an undersupply of vehicles at some locations at the same time as underutilization of vehicles at...

Dynamic Pricing for User-Based Rebalancing in Free-Floating Vehicle Sharing: A Real-World Case

Dynamic pricing can be used for better fleet distribution in free-floating vehicle sharing (FFVS), and thus increase utilization and revenue for the provider by reducing supply-demand asymmetry. Supply-demand asymmetry refers to the existence of an undersupply of vehicles at some locations at the same time as underutilization of vehicles at...

Reade: Connecting People - Users' Dynamics and its Architectural Representation

A rehabilitation Center building proposal in the center of Amsterdam. The design is derived from a research on the main user groups in a rehabilitation center and the dynamics among them, with an architectural result of the representation of these dynamics.
