About The Program
Keysight’s Applied AI Research group is developing adaptive neural modeling frameworks that enable AI systems to evolve across changing simulation, measurement, and experimental conditions. A central challenge is to design neural models that can dynamically adapt their input and output structures —adding or removing signals, channels, or targets—without full retraining or costly reconfiguration.
This internship focuses on building dynamic I/O schema mechanisms for neural networks implemented in libtorch (C++ API for PyTorch) . Your work will enable AI models to flexibly adapt to new use cases, reduce retraining time, and lower compute costs while improving scalability and reusability across Keysight’s engineering AI ecosystem.
Role Overview
As a PhD Intern in Machine Learning Systems , you will design and prototype runtime-adaptive neural models capable of modifying their input/output schemas dynamically.
You will explore how libtorch-based architectures can adjust tensor structures, model heads, and data mappings without full reinitialization—enabling schema-aware, modular AI models .
You’ll collaborate with machine learning, runtime, and simulation experts to integrate these mechanisms into Keysight’s AI modeling stack, driving more efficient, versatile, and future-proof model workflows.
