Kafka-ML: connecting the data stream with ML/AI frameworks

Cristian Martín, Peter Langendoerfer, Pouya Soltani Zarrin et al.

Machine Learning (ML) and Artificial Intelligence (AI) have a dependency on data sources to train, improve and make predictions through their algorithms. With the digital revolution and current paradigms like the Internet of Things, this information is turning from static data into continuous data streams. However, most of the ML/AI frameworks used nowadays are not fully prepared for this revolution. In this paper, we proposed Kafka-ML, an open-source framework that enables the management of TensorFlow ML/AI pipelines through data streams (Apache Kafka). Kafka-ML provides an accessible and user-friendly Web User Interface where users can easily define ML models, to then train, evaluate and deploy them for inference. Kafka-ML itself and its deployed components are fully managed through containerization technologies, which ensure its portability and easy distribution and other features such as fault-tolerance and high availability. Finally, a novel approach has been introduced to manage and reuse data streams, which may lead to the (no) utilization of data storage and file systems.

Providing reliability and auditability to the IoT LwM2M protocol through Blockchain

Cristian Martín, Iván Alba, Joaquín Trillo et al.

Blockchain has come to provide transparency, reliability as well as to increase the security in computer systems, especially in distributed ones like the Internet of Things (IoT). A few integrations have been proposed in this context so far; however, most of these solutions do not pay special attention to the interoperability of the IoT, one of the biggest challenges in this field. In this paper, a Blockchain solution has been integrated into the OMA Lightweight M2M (LwM2M), a promising industry IoT protocol for global interoperability. This integration provides reliability and auditability to the LwM2M protocol enabling IoT devices (LwM2M clients) to transparently interact with the protocol. Furthermore, a missing reliable API to allow users and applications to securely interact with the system and an interface to store critical information like anomalies for auditability have been defined.
