At Estonian local elections in October 2005 for the first time in the world binding country-wide remote Internet voting took place: whole Estonian electorate had a possibility to cast the vote via Internet. Approximately 2 % of actual voters made use of this possibility. The e-voting surveys show that the attitude of the Estonian public toward e-voting was and is positive; gender, income, educa...

The existing (election) voting systems, e.g., representative democracy, have many limitations and often fail to serve the best interest of the people in a collective decision-making process. To address this issue, the concept of liquid democracy has been emerging as an alternative decisionmaking model to make better use of “the wisdom of crowds”. However, there is no known cryptographically sec...

The famous result of Gibbard and Satterthwaite shows that every voting procedure is manipulable if the voters can have any preferences over the candidates. That is, a voter may improve the voting result by not voting according to his true preference. Approval voting, introduced by Brams and Fishburn, is not manipulable if preferences are dichotomous: each voter only distinguishes between accept...

We discuss sincere voting when voters have cardinal preferences over alternatives. We interpret sincerity as opposed to strategic voting, and thus de…ne sincerity as the optimal behavior when conditions to vote strategically diminish. When voting mechanisms allow for only one message type (simple voting mechanisms) we show that eliminating some conditions for strategic voting, individuals’ opti...

Middleware is a class of software systems above the operating system which is becoming widely used for programming distributed systems. Voting is a fundamental operation when distributed systems involve replicated components. However, support for voting in middleware is very limited. This paper describes issues involved with supporting voting, and more general data fusion, in middleware. We des...

Despite the large improvements in performance attained by using deep learning in computer vision, one can often further improve results with some additional post-processing that exploits the geometric nature of the underlying task. This commonly involves displacing the posterior distribution of a CNN in a way that makes it more appropriate for the task at hand, e.g. better aligned with local im...
