The Herglotz's Theorems & Some Applications
 
56:44
We first recall two classical theorems of Gustav Herglotz on integral representations of positive harmonic functions and of holomorphic functions with positive real part. As a first application, we present a short proof of Caratheodory's Theorem for characterization of holomorphic functions with positive real part in terms of the Toeplitz kernel of the Taylor coefficients of the functions. After recalling the Stieltjes Inversion Formula we provide a second application to the spectral theory of linear operators in indefinite inner product spaces.

Authors: Anna Mándli, Robert Bosch LLC. Rui Li, SAS Institute Inc. Pu Wang, SAS Institute Inc. Abstract: Pu Wang: Automatic Singular Spectrum Analysis and Forecasting The singular spectrum analysis (SSA) method of time series analysis applies nonparametric techniques to decompose time series into principal components. SSA is particularly valuable for long time series, in which patterns (such as trends and cycles) are difficult to visualize and analyze. An important step in SSA is determining the spectral groupings; this step can be automated by analyzing the w-correlations (weighted correlations) of the spectral components. To illustrate, monthly data on temperatures in the United States for about the last 100 years are analyzed to discover significant patterns. Rui Li: Short-Term Wind Energy Forecasting with Temporally Dependent Neural Network Models As the penetration of renewable energy into the electrical grid is increasing worldwide, accurate forecasting of renewable energy generation is essential not only for grid operation and reliability, but also for energy trading and long-term planning. In this paper, we focus on short-term wind energy forecasting. The inherent variability and unpredictability of wind energy imposes great challenges upon many models. Conventional time series models, such as ARIMAX, often fail to capture nonlinear patterns in energy output, and a feedforward artificial neural network doesn’t take temporal dependency into account. In this paper, we apply state-of-art autoregressive artificial neural network (AR-ANN) models and recurrent neural network (RNN) models to wind energy forecasting. By capturing both the sequential pattern of energy output and the complex relationship between weather predictors and power generation, we can achieve better forecasting accuracy. These temporally dependent neural network structures can also be easily extended to model other nonlinear time series and temporal data. Anna Mándli: Time Series Classification for Scrap Rate Prediction in Transfer Molding In this paper, we present and evaluate methods for predicting critical increase in manufacturing scrap rate of automotive electronic products. Along with information on processes such as maintenance cycles, we analyze the sensor time series of the so-called transfer molding process, in which the electronic product is packaged into plastic for protection. Production data are organized in a two level hierarchy of the individual parts and of the sequence of parts. Since the main goal is to predict and warn about the future state of the process, we designed a training and prediction framework over certain production cycles. By using sensor and other information, we adapt known time series classifi- cation methods to predict increase in scrap rate in the near future. By using three months of manufacturing time series, we evaluate both feature based and dynamic time warping based methods that are capable of fusing a large number of production time series. As a main conclusion, we may warn the operators of increase in failures with an AUC above 0.7 by combining multiple approaches in our final classifier ensemble.

Numerical weather prediction
 
29:58
Numerical weather prediction uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. Though first attempted in the 1920s, it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic results. A number of global and regional forecast models are run in different countries worldwide, using current weather observations relayed from radiosondes, weather satellites and other observing systems as inputs. Mathematical models based on the same physical principles can be used to generate either short-term weather forecasts or longer-term climate predictions; the latter are widely applied for understanding and projecting climate change. The improvements made to regional models have allowed for significant improvements in tropical cyclone track and air quality forecasts; however, atmospheric models perform poorly at handling processes that occur in a relatively constricted area, such as wildfires.

Abstract: I will discuss the multifractal spectrum of the intersection of chordal SLEκ curves with the real line. For κ greater than 4, this intersection is a random fractal of almost sure Hausdorff dimension min 2−8/κ,1. We study the random sets of points at which the curve collides with the real line at a specified angle - or, equivalently, the local dimension of harmonic measure is prescribed - and compute an almost sure dimension spectrum describing the metric size of these sets. The talk is based on a joint work with Tom Alberts, Utah and Fredrik Viklund, KTH.

Pierre Del Moral, INRIA (Bordeaux-Sud Ouest Research Center) Ensemble Kalman-Bucy filters
 
45:01
London Probability Seminar 4/11/2016 https://nms.kcl.ac.uk/probability/events.php?pastFuture=past Pierre Del Moral, INRIA (Bordeaux-Sud Ouest Research Center) On the stability and the uniform propagation of chaos properties of Ensemble Kalman-Bucy filters The Ensemble Kalman filter is a sophisticated and powerful data assimilation method for filtering high dimensional problems arising in fluid mechanics and geophysical sciences. This Monte Carlo method can be interpreted as a mean-field McKean-Vlasov type particle interpretation of the Kalman-Bucy diffusions. In contrast to more conventional particle filters and nonlinear Markov processes these models are designed in terms of a diffusion process with a diffusion matrix that depends on particle covariance matrices. Besides some recent advances on the stability of nonlinear Langevin type diffusions with drift interactions, the long-time behaviour of models with interacting diffusion matrices and conditional distribution interaction functions has never been discussed in the literature. One of the main contributions of the article is to initiate the study of this new class of models The article presents a series of new functional inequalities to quantify the stability of these nonlinear diffusion processes. In the same vein, despite some recent contributions on the convergence of the Ensemble Kalman filter when the number of sample tends to infinity very little is known on stability and the long-time behaviour of these mean-field interacting type particle filters. The second contribution of this article is to provide uniform propagation of chaos properties as well as Lp-mean error estimates w.r.t. to the time horizon. Our regularity condition is also shown to be sufficient and necessary for the uniform convergence of the Ensemble Kalman filter. The stochastic analysis developed in this article is based on an original combination of functional inequalities and Foster-Lyapunov techniques with coupling, martingale techniques, random matrices and spectral analysis theory. This is joint work with Julian Tugaut.

Growth of (finite) Perturbations in Spatiotemporal Systems. Application to Ensemble Weather Fore...
 
01:08:12
- By: José Manuel Gutiérrez Llorente, Instituto de Física de Cantabria - IFCA (CSIC-UC), Santander - Date: 2012-05-23 14:30:00 - Description: Modern meteorology is concerned with the nonlinear dynamics of the atmosphere and ocean (ensemble prediction, etc.). However, although low dimensional chaos is nowadays well known, much less is understood about spatiotemporal systems with a large number of degrees of freedom, as those describing the atmosphere-ocean evolution. The nonlinear effects that drive the dynamics of finite perturbations are a key factor for the understanding of error growth and ensemble prediction in these systems. However, most of the methods used currently in meteorology rely on findings from the low dimensional world and do not take into account the interactions between space and time inherent of these systems. In this talk we focus on the singular features of spatiotemporal chaos, as opposed to low-dimensional dynamics, paying attention to the interplay between spatial and temporal dynamics. To this aim we consider not only infinitesimal dynamics (characterized by the Lyapunov spectrum), but also the properties of finite growth in the edge of predictability. A recent analogy introduced with the scaling (fractal) growth of rough interfaces (such as the propagation of a fire interface in a sheet of paper) provides a framework for the analysis and characterization of the spatial and temporal dynamics of these systems, and their interplay. As an illustrative example we analyze data from the DEMETER project, an state-of-the-art ensemble forecast system for seasonal forecasting, which includes multiple models and initial conditions.

I just experienced a visible cloud of energy, which moved down the river I was next to. It was singular, with no other "clouds" or "must" around. It was "raining" energy inside the cloud itself, which I felt as it passed through me. So I'm wondering if anyone else has experienced anything like this, or any other unusual events recently? I and I'm sure many more, would love to hear your experiences if you'd care to share them in the comments below.

As an intuitive empath and a physical channel, I feel and see energy very intensely. I use the expanded information that I access, along with cutting edge quantum information, to help us paint a clearer picture of what's currently happening to humanity and our planet. 🌈🌎🌈 I work with people both one-to-one and in groups, to assist them in accessing the abilities of their true inner being. In this way, I kind of hold the bicycle seat for others, accessing the energies, so that they can access their own magic and miracles in the spiritual world. I find that this helps people step into their own life's purpose and understand the larger story of what's currently taking place on the planet today.

Randomized Low-Rank Approximation and PCA: Beyond Sketching, Cameron Musco
 
22:58
I will discuss recent work on randomized algorithms for low-rank approximation and principal component analysis (PCA). The talk will focus on efforts that move beyond the extremely fast, but relatively crude approximations offered by random sketching algorithms. In particular, we will see how advances in Johnson-Lindenstrauss projection methods have provided tools for improving the analysis of classic iterative SVD algorithms, including the block power method and block Krylov methods. The key insight is to view the iterative algorithms as denoising procedures for coarse sketching methods. I will discuss how this view can be used to analyze a simple block Krylov method, showing that the algorithm gives (1+epsilon) near optimal PCA and low-rank approximation in just O(1/sqrtepsilon) iterations. Despite their long history, this analysis is the first of a Krylov subspace method that does not depend on the matrixs spectral gaps. I will also survey open questions in the analysis of iterative methods, promising work on approximate PCA via stochastic optimization, fast sampling methods for low-rank kernel matrix approximation, and faster techniques for singular value decomposition targeted at specific downstream tasks, such as principal component regression.
