Thesis Abstract The aim of this work is to address two major weaknesses of existing database interfaces by: developing eeective tools for the implementation of tailorable database interfaces, and developing eeective visualisations of sophisticated data modelling constructs. The thesis introduces an integrated approach, whereby an object-oriented graphical toolkit is fully integrated with an obj...

In this paper we propose a simple and efficient method for improving stochastic gradient descent methods by using feedback from the objective function. The method tracks the relative changes in the objective function with a running average, and uses it to adaptively tune the learning rate in stochastic gradient descent. We specifically apply this idea to modify Adam, a popular algorithm for tra...

As is well known, the Bible opens with the Creation and recounts the carefree life of the first two people in Paradise. This blissful state soon comes to an end when Adam and Eve are driven from Paradise. Eve is told: “In pain shall you bring forth children, yet your desire shall be for your husband” (Gen. 3, xvi). “Now Adam knew Eve his wife, and she conceived and bore Cain, saying, I have got...

Robot game is a two-player vector addition game played on the integer lattice Z. Both players have sets of vectors and in each turn the vector chosen by a player is added to the current configuration vector of the game. One of the players, called Eve, tries to play the game from the initial configuration to the origin while the other player, Adam, tries to avoid the origin. The problem is to de...
