A Review and Characterization of Progressive Visual Analytics

open access: yesInformatics, 2018
Progressive Visual Analytics (PVA) has gained increasing attention over the past years. It brings the user into the loop during otherwise long-running and non-transparent computations by producing intermediate partial results.

An Online Algorithm for Smoothed Online Convex Optimization [PDF]

open access: yesACM SIGMETRICS Performance Evaluation Review, 2019
We consider Online Convex Optimization (OCO) in the setting where the costs are m-strongly convex and the online learner pays a switching cost for changing decisions between rounds. We show that the recently proposed Online Balanced Descent (OBD) algorithm is constant competitive in this setting, with competitive ratio 3+O(1/m), irrespective of the ...

Adaptive Online Learning for the Autoregressive Integrated Moving Average Models

open access: yesMathematics, 2021
This paper addresses the problem of predicting time series data using the autoregressive integrated moving average (ARIMA) model in an online manner. Existing algorithms require model selection, which is time consuming and unsuitable for the setting of ...

To Transfer or Not: An Online Cost Optimization Algorithm for Using Two-Tier Storage-as-a-Service Clouds

open access: yesIEEE Access, 2019
Currently, Storage-as-a-Service (StaaS) clouds offer multiple data storage and access pricing options which usually consist of hot and cold tiers. The cold tier storage option offers a lower storage price while the hot tier storage option offers a lower ...

Online algorithms for market clearing

open access: yesJournal of the ACM, 2006
In this article, we study the problem of online market clearing where there is one commodity in the market being bought and sold by multiple buyers and sellers whose bids arrive and expire at different times. The auctioneer is faced with an online clearing problem of deciding which buy and sell bids to match without knowing what bids will ...

Online Graph Algorithms with Predictions [PDF]

open access: yes, 2022
Online algorithms with predictions is a popular and elegant framework for bypassing pessimistic lower bounds in competitive analysis. In this model, online algorithms are supplied with future predictions, and the goal is for the competitive ratio to smoothly interpolate between the best offline and online bounds as a function of the prediction error ...

Formal Analysis of Online Algorithms [PDF]

open access: yes, 2011
In [2], we showed how viewing online algorithms as reactive systems enables the application of ideas from formal verification to the competitive analysis of online algorithms. Our approach is based on weighted automata, which assign to each input word a cost in R≥0.
