Flat Minima

Neural Computation, 1997
We present a new algorithm for finding low-complexity neural networks with high generalization capability. The algorithm searches for a “flat” minimum of the error function. A flat minimum is a large connected region in weight space where the error remains approximately constant.

Flat and weakly flat projection algebras

Algebra Universalis, 2002
The concept of a projection algebra was introduced by \textit{H.\ Ehrig} and his collaborators as an algebraic version of ultrametric spaces. This concept is useful in computer science as a convenient tool for algebraic specification of process algebras. By \(\mathcal{PRO}\) is denoted the category of projection algebras.

FlatQuant: Flatness Matters for LLM Quantization

International Conference on Machine Learning
Recently, quantization has been widely used for the compression and acceleration of large language models (LLMs). Due to the outliers in LLMs, it is crucial to flatten weights and activations to minimize quantization error with equally spaced ...

Numerical and experimental analysis of strip cross-directional control and flatness prediction for UCM cold rolling mill

Journal of Manufacturing Processes, 2018
In cold rolling of strip, flatness defects typically appear in strip when subjected to heterogeneous thickness reductions across the width of strip.

Fixed-time trajectory tracking for a quadrotor with external disturbances: A flatness-based sliding mode control approach

Aerospace Science and Technology, 2019
This study proposes a flatness-based fixed-time sliding mode control strategy to address the trajectory tracking problem for a quadrotor with external disturbances. Based on the differential flatness theory, the underactuated dynamics of the quadrotor is

Flat Frog

ACM SIGGRAPH 2012 Computer Animation Festival, 2012
Flat Frog is based on the misadventures of two rustic frogs that are always anxious to cross the road in search of females. Ever the ignorant optimists, the two rubes manage to get run over again and again out on the road but this never seems to dampen.

Flatness-Based Model Predictive Control for Quadrotor Trajectory Tracking

IEEE/RJS International Conference on Intelligent RObots and Systems, 2018
The use of model predictive control for quadro-tor applications requires balancing trajectory tracking performance and constraint satisfaction with fast computation.

Pullback-Flat Acts are Strongly Flat

Canadian Mathematical Bulletin, 1991
AbstractLet 5 be a monoid. A right S-system A is called strongly flat if the functor A ⊗ — (from the category of left S-systems into the category of sets) preserves pullbacksand equalizers. (This concept arises in B. Stenström, Math. Nachr. 48(1971), 315-334 under the name weak flatness). The main result of the present paper is a proof that for A to be

Modeling flatness deviation in face milling considering angular movement of the machine tool system components and tool flank wear

Precision engineering, 2018
The torsional angle, χYDeg, of a machine tool-device-spindle unit is formulated in a face-milling operation. As there is no angular compliance in the technical specifications for the machine tool, a novel method is proposed for the determination of the ...

Of Mud Flats, Mixed Mud Flats and Sand Flats

German Research, 2004
AbstractThe extended tidal mud flats found in various climate zones are a result of the tides. Using the southern North Sea as their research area, scientists study how ecological processes operate in the threatened “Wadden Sea ...
