As Language Models Scale, Low-order Linear Depth Dynamics Emerge
Buddhika Nettasinghe, Geethu Joseph
Large language models are often viewed as high-dimensional nonlinear systems and treated as black boxes. Here, we show that transformer depth dynamics admit accurate low-order line…

Minimal Actuator Selection for Linear Time Invariant Systems
Luca Ballotta, Geethu Joseph
Selecting a few available actuators to ensure the controllability of a linear system is a fundamental problem in control theory. Previous works either focus on optimal performance,…

Pointwise-Sparse Actuator Scheduling for Linear Systems with Controllability Guarantee
Luca Ballotta, Geethu Joseph, Irawati Rahul Thete
This paper considers the design of sparse actuator schedules for linear time-invariant systems. An actuator schedule selects, for each time instant, which control inputs act on the…
