Rock Paper Scissor Game through Actor Model in Scala

4 minute read

I had an opportunity to attend a wonderful course during my first year of Ph.D. at the GSSI. The course was offered by Prof. Rocco De Nicola. It was on The principles of Concurrent and Distributed Programming. One of the projects for the course was to develop a program to simulate a three-player distributed Rock/ Paper/Scissor Game. It’s a game we all would have played at some point in our lives.

A Machine Learning-Driven Approach for Proactive Decision Making in Adaptive Architectures

Published in International Conference on Software Architecture (ICSA) 2019, Hamburg, Germany, 2019

Self-adaptation is nowadays considered to be the best solution to dynamically reconfigure a system in the occurrence of deviations from the expected quality of service (QoS) parameters. However, data-and event-driven systems, such as IoT applications, impose new heterogeneity, interoperability, and distribution issues, that make uncertainty on the QoS stability even harder. Typical adaption techniques make use of reactive approaches, an after-the-fact adaptation that starts when the system deviates from the expected QoS parameters. What we envision is instead a proactive approach to anticipate the changes before the event of a QoS deviation. More specifically, we propose IoTArchML, a machine learning-driven approach for decision making in aiding proactive architectural adaptation of IoT system. The approach i) continuously monitors the QoS parameters; ii) predicts, based on historical data, possible deviations from the acceptable QoS parameters; iii) considers a list of possible alternative solutions to prevent the QoS deviation; iv) selects the optimal solution from the list; and v) checks whether the envisioned solution satisfies the overall system QoS requirements. We, therefore, move the focus from self-adaptive architectures to self-learning architectures, enabling the architectures to learn and improve over a period of time.

ArchLearner: leveraging machine-learning techniques for proactive architectural adaptation

Published in European Conference on Software Architecture (ECSA) 2019, Paris, France, 2019

Self-adaptation is nowadays considered as one of the possible solutions to handle the uncertainties faced by software at run-time. This is especially true in the case of IoT systems. These uncertainties can, in turn, affect the system QoS (Quality Of Service). In this tool demo, we present a machine learning driven proactive decision-making tool named ArchLearner, for aiding architectural adaptation. The tool enables the given IoT system to i) automatically identify the need for adaptation at an early stage; ii) perform automated decision making for generating the best adaptation strategy; iii) gather the feedback of the selected decision for continuous improvement. It also enables the architects/developers to i) visualize the adaptation process in near real-time; ii) specify the required configurations; iii) visualize the real-time QoS data.
