Design of Low-power Analog Circuits in Advanced Technology Nodes using the Gm/ID Approach

Simon Olivier Berner, Christian Enz, Hung-Chi Han

The Gm/ID approach has proven to be an efficient technique for the design of low-power analog circuits. Until now it was mostly demonstrated on older CMOS technology nodes. In this paper we will show that the Gm/ID methodology still holds for advanced tech ...

On the Granularity of Explanations in Model Agnostic NLP Interpretability

Pascal Frossard, Yves Rychener

Current methods for Black-Box NLP interpretability, like LIME or SHAP, are based on altering the text to interpret by removing words and modeling the Black-Box response. In this paper, we outline limitations of this approach when using complex BERT-based c ...

Bitfiltrator: A general approach for reverse-engineering Xilinx bitstream formats

James Richard Larus, Sahand Kashani, Seyedmahyar Emami

As the usage of FPGAs spreads, engineers will inevitably employ them in ways unforeseen-or unwanted-by their manufacturers. Xilinx's toolchains offer multiple points for customizing the FPGA compilation flow, but all flows must end with Vivado as it is the ...

Implicit Gradient Alignment in Distributed and Federated Learning

Martin Jaggi, Yatin Dandi, Luis Felipe Barba Flores

A major obstacle to achieving global convergence in distributed and federated learning is the misalignment of gradients across clients, or mini-batches due to heterogeneity and stochasticity of the distributed data. In this work, we show that data heteroge ...

An Accelerated First-Order Method for Non-convex Optimization on Manifolds

Christopher Arnold Criscitiello, Nicolas Boumal

We describe the first gradient methods on Riemannian manifolds to achieve accelerated rates in the non-convex case. Under Lipschitz assumptions on the Riemannian gradient and Hessian of the cost function, these methods find approximate first-order critical ...
