• Abstract: Discussions on indeterminism in physics focus on the possibility of an open future, i.e. the possibility of having potential alternative future events, the realisation of one of which is not fully determined by the present state of affairs. Yet, can indeterminism affect also the past, making it open as well? We show that by upholding principles of finiteness of information one can entail such a possibility. We provide a toy model that shows how the past could be fundamentally indeterminate, while also explaining the intuitive (and observed) asymmetry between the past -- which can be remembered, at least partially -- and the future -- which is impossible to fully predict.

  Under dynamic traffic scenarios, planning based on deterministic predictions is not trustworthy. The authors propose to quantify uncertainty during forecasting using approximation which deterministic approaches fail to capture. The effect of dropout weights and long-term prediction on future state uncertainty has been studied.

  We take a step back to analyze how the human capability to anticipate the future can be transferred to machine learning algorithms. A recent study on human psychology explains that, in anticipating an occurrence, the human brain counts on both systems. In this work, we study the impact of each system for the task of action anticipation and introduce a paradigm to integrate them in a learning framework.

• Prospective Learning: Principled Extrapolation to the Future [45.287871145154135]
  Learning evolve a process which can update decision rules based on past experience such that future performance improves. Traditionally machine learning is often evaluated under the assumption that the future will be identical to the past in distribution or adversarial dynamics. Here we reformulate the learning problem to one that centers around this idea of dynamic futures that are partially learnable. We argue that prospective learning more accurately characterizes many real world problems that (1) currently lack adequate explanations for how natural intelligences solve them.

• Dense Uncertainty Estimation via an Ensemble-based Conditional Latent Variable Model [68.34559610536614]
  We argue that the aleatoric uncertainty is an inherent attribute of the data and can only be correctly estimated with an unbiased oracle model. We propose a new sampling and selection strategy at train time to approximate the oracle model for aleatoric uncertainty estimation. Our results show that our solution achieves both accurate deterministic results and reliable uncertainty estimation.

• The quantum mechanics of the present [0.0]
  We propose a reformulation of quantum mechanics in which the distinction between definite and indefinite becomes the fundamental primitive. Inspired by suggestions of Heisenberg, Schrodinger and Dyson, we propose that the distinction between past, present and future is derivative of the fundamental distinction between indefinite and definite.

• Why the Future Cannot be Open in the Quantum World [0.0]
  An open future means that the value observed when measuring a physical quantity in the future is not determined. Many interpretations regard quantum mechanics as deterministic. I argue that, although quantum mechanics cannot predict the future with certainty, the quantum mechanical world must be deterministic.

  Credit assignment in reinforcement learning is the problem of measuring an action's influence on future rewards. We adapt the notion of counterfactuals from causality theory to a model-free RL setup. We formulate a family of policy algorithms that use future-conditional value functions as baselines or critics, and show that they are provably low variance.

  In the wild, a plausible succession of events is governed by the rules of causality which cannot easily be derived from a finite training set. We propose a novel theoretical framework to perform causal-temporal future prediction by embedding information on spacetime. We demonstrate successful applications in causal imagetemporal and future video frame prediction on a dataset of images.

• Indeterminism, causality and information: Has physics ever been deterministic? [0.0]
  We show that there exist alternative stories to be told in which classical mechanics can be interpreted as a fundamentally indeterministic theory. On the one hand, this leaves room for the many possibilities of an open future, yet, it brings into classical physics some of the conceptual issues typical of quantum mechanics.
