### Event Detection in Noisy Streaming Data with Combination of Corroborative and Probabilistic Sources. (arXiv:1911.09281v1 [cs.LG])

Global physical event detection has traditionally relied on dense coverage of physical sensors around the world; while this is an expensive undertaking, there have not been alternatives until recently. The ubiquity of social networks and human sensors in the field provides a tremendous amount of real-time, live data about true physical events from around the…

### Band-limited Training and Inference for Convolutional Neural Networks. (arXiv:1911.09287v1 [cs.LG])

The convolutional layers are core building blocks of neural network architectures. In general, a convolutional filter applies to the entire frequency spectrum of the input data. We explore artificially constraining the frequency spectra of these filters and data, called band-limiting, during training. The frequency domain constraints apply to both the feed-forward and back-propagation steps. Experimentally,…

### Mixed curvature almost flat manifolds. (arXiv:1911.09212v1 [math.DG])

We prove a mixed curvature analogue of Gromov’s almost flat manifolds theorem for upper sectional and lower Bakry-Emery Ricci curvature bounds.

### Fast Non-Parametric Learning to Accelerate Mixed-Integer Programming for Online Hybrid Model Predictive Control. (arXiv:1911.09214v1 [math.OC])

Today’s fast linear algebra and numerical optimization tools have pushed the frontier of model predictive control (MPC) forward, to the efficient control of highly nonlinear and hybrid systems. The field of hybrid MPC has demonstrated that exact optimal control law can be computed, e.g., by mixed-integer programming (MIP) under piecewise-affine (PWA) system models. Despite the…

### On the Discretization of Robust Exact Filtering Differentiators. (arXiv:1911.09232v1 [eess.SY])

This paper deals with the design of discrete-time algorithms for the robust filtering differentiator. Two discrete-time realizations of the filtering differentiator are introduced. The first one, which is based on an exact discretization of the continuous differentiator, is an explicit one, while the second one is an implicit algorithm which enables to remove the numerical…

### Iterative Peptide Modeling With Active Learning And Meta-Learning. (arXiv:1911.09103v1 [q-bio.BM])

Often the development of novel materials is not amenable to high-throughput or purely computational screening methods. Instead, materials must be synthesized one at a time in a process that does not generate significant amounts of data. One way this method can be improved is by ensuring that each experiment provides the best improvement in both…

### Autoregressive Modeling of Forest Dynamics. (arXiv:1911.09182v1 [q-bio.QM])

In this work, we employ autoregressive models developed in financial engineering for modeling of forest dynamics. Autoregressive models have some theoretical advantage over currently employed forest modeling approaches such as Markov chains and individual-based models, as autoregressive models are both analytically tractable and operate with continuous state space. We perform time series statistical analysis of…
