Photo of the week: Autumn in the garden
Ich bleibe beim herbstlichen Thema. Hier ist der wilde Wein (der vermutlich kein wilder Wein, sondern ein anderes Rankgewächs ist) erst dabei, sich rot zu verfärben. Heute strahlt die ganze hintere Gartenecke in leuchtendem Rot. Sonnige Oktobertage sind mit das beste am Jahr.

Accelerated Gradient Methods with Biased Gradient Estimates: Risk Sensitivity, High-Probability Guarantees, and Large Deviation Bounds
We study trade-offs between convergence rate and robustness to gradient errors in first-order methods. Our focus is on generalized momentum methods (GMMs), a class that includes Nesterov's accelerated gradient, heavy-ball, and gradient descent. We allow stochastic gradient errors that may be adversarial and biased, and quantify robustness via the risk-sensitive index (RSI) from robust control theory. For quadratic objectives with i.i.d. Gaussian noise, we give closed-form expressions for RSI us…

Is a Dissipative System Always a Gradient System or a Gradient Like System?
We find that to the dynamics of a given dissipative system a $p=1$ differential form can be associated with a general decomposition into a potential term and a non-potential residual part. If the residual part is absent the form is closed and the system is gradient system or gradient like. If it is non-closed, in the differential form approach, it remains non-closed under a variable change of coordinates, i.e., the system is not a gradient one or a gradient like in any coordinate system. On the…
