Repository made for the Final Project of the Social Networks & Online Markets Course of the Masters in Data Science Course at the Sapienza University of Rome. The main purpose of the project was assessing the effect of link recommenders on emergent phenomena like popularity bias, the echo chamber effect and polarization on networks.

Simulation of Opinion Dynamics models on graphs

Uncertainty-driven heterogeneous collective opinion dynamics, corresponding to the manuscript entitled "Leveraging Uncertainty in Collective Opinion Dynamics with Heterogeneity"

Agent-based simulation of social interaction (Social Force Model and Self-Propelled Brownian Particles)

Spreading Processes on Networks

This depository contains the code to run PASOM--An agent-based model simulating science attitudes. Outputs from the simulations were used for the paper, “Toxic behaviour facilitates echo chamber formation: An agent-based modelling simulation of science attitudes based on Spiral of Silence Theory” submitted to Plos One.

Multi-Agent Simulation of Collective Behavior (Pedestrian Crowd)

Estimate perceived and actual opinion polarisation from multi-wave cross-sectional survey data (here the European Social Survey)

Network Diffusion Library - (for NetworkX and iGraph)

Python implementation of the noisy voter model with poll-induced delays.

Networks, beliefs, and asset prices: codes

Continuous-time noisy voter model

Code for Maths in Action Dissertation Project

Dataset & code used in "Modelling and Predicting Online Vaccination Views Using Bow-tie Decomposition"

Convenient exit time & exit probability plot creator for q-voter model on graphs

Homework and exercises from course Network Dynamics and Learning

"Tensor Decomposition to Capture Spatiotemporal Patterns of Coupled Oscillator and Opinion Dynamics" by Agam Goyal and Hanbaek Lyu

Software that simulates voting processes and compares electoral systems. A network of voters is generated by the Stochastic Block Model or a distance-based model. Opinion dynamics are run on the network with options for zealots and media bias. Different electoral systems are supported with high flexibility to accommodate real-world systems.”
