Beyond Model Readiness: Institutional Readiness for AI Deployment in Public Systems
Erika Fille Legara, Elmo Domino Jose, Paula Joy Martinez
Many public-sector artificial intelligence systems fail not at the point of model development, but at the point of deployment. Systems that perform well in internal testing may sti…
The Hamilton-Jacobi Theory of Deep Learning
Jose Marie Antonio Miñoza, Erika Fille T. Legara, Christopher P. Monterola
In this paper, training a neural network is identified, exactly, as a search through Hamilton--Jacobi initial-value problems: each gradient step selects the initial data of a visco…
Student Flow Modeling for School Decongestion via Stochastic Gravity Estimation and Constrained Spatial Allocation
Sebastian Felipe R. Bundoc, Paula Joy B. Martinez, Sebastian C. Ibañez +1
School congestion, where student enrollment exceeds school capacity, is a major challenge in low- and middle-income countries. It highly impacts learning outcomes and deepens inequ…
An analysis of network filtering methods to sovereign bond yields during COVID-19
Raymond Ka-Kay Pang, Oscar Granados, Harsh Chhajer +1
In this work, we investigate the impact of the COVID-19 pandemic on sovereign bond yields. We consider the temporal changes from financial correlations using network filtering meth…
Phase Transition in Taxi Dynamics and Impact of Ridesharing
Bo Yang, Shen Ren, Erika Fille Legara +4
We develop a numerical model using both artificial and empirical inputs to analyze taxi dynamics in an urban setting. More specifically, we quantify how the supply and demand for t…
Spatial Patterns in Urban Systems
Hoai Nguyen Huynh, Evgeny Makarov, Erika Fille Legara +2
Understanding the morphology of an urban system is an important step toward unveiling the dynamical processes of its growth and development. At the foundation of every urban system…
A Dynamical Model of Twitter Activity Profiles
Hoai Nguyen Huynh, Erika Fille Legara, Christopher Monterola
The advent of the era of Big Data has allowed many researchers to dig into various socio-technical systems, including social media platforms. In particular, these systems have prov…
Inferring Passenger Type from Commuter Eigentravel Matrices
Erika Fille Legara, Christopher Monterola
A sufficient knowledge of the demographics of a commuting public is essential in formulating and implementing more targeted transportation policies, as commuters exhibit different…
Simulating Congestion Dynamics of Train Rapid Transit using Smart Card Data
Nasri Bin Othman, Erika Fille Legara, Vicknesh Selvam +1
Investigating congestion in train rapid transit systems (RTS) in today's urban cities is a challenge compounded by limited data availability and difficulties in model validation. H…
Agent-based model of competition in a social structure
Erika Fille Legara, Anthony Longjas, Rene Batac
Indirect competition emerged from the complex organization of human societies, and knowledge of the existing network topology may aid in developing effective strategies for success…
