He has authored four books (10 editions) on computer architecture, now used in more than 120 universities around the world.

Abstract

Machine Learning (ML) has now taken over as the preferred method for building intelligent applications. Correspondingly, since ML systems are predominantly software applications, the software development process has transitioned from the traditional behavior-oriented process (programming) to a data-oriented process. Ideally, the ML system development workflow should follow the Software Development Life Cycle (SDLC) processes to utilize the lessons learned in traditional systems development. However, the data-centric nature of ML systems does not cater completely to this integration. This talk presents the state-of-the-art in Machine Learning System Development Lifecycle (ML SDLC) and brief descriptions of Machine Learning Operations (MLOps). Although the industry has undertaken significant measures to streamline the ML system development and deployment and several new processes are proposed by researchers, there is no accepted standard for the MLSDLC. In addition, with the current emphasis on building trustable ML/AI systems, their security mechanisms and explainability of prediction features have also become important, especially for critical applications. As such, we propose a security and explainability augmented ML system development life cycle.
