Content: How glass box models can provide X AI without compromising resultsPhoto by on These models are often referred to as black box models. We have set of input features, then we give these features to our model, which then does complex calculation, and comes to decision. However, we do not know exactly how the model comes to its decisions, which features it finds important or even what it looks at. In some cases, it is not terribly important for humans to fully understand how the model works...

Content: Typically, fair machine learning research focuses on a single decisionmaker and assumes that the underlying population is stationary. However, many of the critical domains motivating this work are characterized by competitive marketplaces with many decisionmakers. Realistically, we might expect only a subset of them to adopt any non-compulsory fairness-conscious policy, a situation that political philosophers call partial compliance. This possibility raises important questions: how does the stra...

Content: Energy-based models (EBMs) are a simple yet powerful framework for generative modeling. They are based on a trainable energy function which defines an associated Gibbs measure, and they can be trained and sampled from via well-established statistical tools, such as MCMC. Neural networks may be used as energy function approximators, providing both a rich class of expressive models as well as a flexible device to incorporate data structure. In this work we focus on shallow neural networks. Buildin...

Content: In this paper we develop a concrete and fully implementable approach to the optimization of functionally generated portfolios in stochastic portfolio theory. The main idea is to optimize over a family of rank-based portfolios parameterized by an exponentially concave function on the unit interval. This choice can be motivated by the long term stability of the capital distribution observed in large equity markets, and allows us to circumvent the curse of dimensionality. The resulting optimization...

Content: \textit{Stochastic gradient descent} (SGD) is of fundamental importance in deep learning. Despite its simplicity, elucidating its efficacy remains challenging. Conventionally, the success of SGD is attributed to the \textit{stochastic gradient noise} (SGN) incurred in the training process. Based on this general consensus, SGD is frequently treated and analyzed as the Euler-Maruyama discretization of a \textit{stochastic differential equation} (SDE) driven by either Brownian or L\'evy stable moti...

We engineer a noise model that combines all three noise channels and simulates the evolution of the quantum computer using its calibrated erro...

Content: An unobservable form of retrocausality is at the center of this work. It emerges by legitimately time-symmetrizing the quantum description of the reversible process between two one-to-one correlated measurement outcomes. This leaves the quantum description unaltered but shows that it is the quantum superposition of unobservable time-symmetrization instances each of which hosts a causal loop: a quantum measurement that retrocausally changes the input state of the unitary transformation that led t...
