Improving Dribbling, Passing, and Marking Actions in Soccer Simulation 2D Games Using Machine Learning

1 code implementation7 Jan 2024 Nader Zare, Omid Amini, Aref Sayareh, Mahtab Sarvmaili, Arad Firouzkouhi, Stan Matwin, Amilcar Soares

The RoboCup 2D Soccer Simulation League is a stochastic, partially observable soccer environment in which 24 autonomous agents play on two opposing teams.

Denoising Opponents Position in Partial Observation Environment

no code implementations23 Oct 2023 Aref Sayareh, Aria Sardari, Vahid Khoddami, Nader Zare, Vinicius Prado da Fonseca, Amilcar Soares

Our idea is to predict opponent positions while they have yet to be seen in a finite number of cycles using machine learning methods to make more accurate actions such as pass.

Pyrus Base: An Open Source Python Framework for the RoboCup 2D Soccer Simulation

1 code implementation22 Jul 2023 Nader Zare, Aref Sayareh, Omid Amini, Mahtab Sarvmaili, Arad Firouzkouhi, Stan Matwin, Amilcar Soares

To conquer the challenges of C++ base codes and provide a powerful baseline for developing machine learning concepts, we introduce Pyrus, the first Python base code for SS2D.

A semi-supervised methodology for fishing activity detection using the geometry behind the trajectory of multiple vessels

1 code implementation12 Jul 2022 Martha Dais Ferreira, Gabriel Spadon, Amilcar Soares, Stan Matwin

To this end, we leverage the unsupervised nature of cluster analysis to label the trajectory geometry highlighting the changes in the vessel's moving pattern which tends to indicate fishing activity.
