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…
Minimal Input Structural Modifications for Strongly Structural Controllability
Geethu Joseph, Shana Moothedath, Jiabin Lin
This paper studies the problem of modifying the input matrix of a structured system to make the system strongly structurally controllable. We focus on the generalized structured sy…
