Book Description
April 2018 Full COLOR 8 1/2 by 11 inches The Public Assistance Program and Policy Guide provides an overview of the Presidential declaration process, the purpose of the Public Assistance (PA) Program, and the authoritiesauthorizing the assistance that the Federal Emergency Management Agency provides under the PA Program. It provides PA policy language to guide eligibility determinations. Overarching eligibility requirements are presented first and are not reiterated for each topic. It provides a synopsis of the PA Program implementation process beginning with pre-declaration activities and continuing through closeout of the PA Program award. When a State, Territorial, or Indian Tribal Government determines that an incident may exceed State, Territorial, Indian Tribal, and local government capabilities to respond, it requests a joint Preliminary Damage Assessment (PDA) with the Federal Emergency Management Agency (FEMA). Federal, State, Territorial, Indian Tribal, local government, and certain private nonprofit (PNP) organization officials work together to estimate and document the impact and magnitude of the incident.

Mathematics for Machine Learning
Author: Marc Peter Deisenroth
Publisher: Cambridge University Press
ISBN: 1108569323
Category : Computers
Languages : en
Pages : 392
Book Description
The fundamental mathematical tools needed to understand machine learning include linear algebra, analytic geometry, matrix decompositions, vector calculus, optimization, probability and statistics. These topics are traditionally taught in disparate courses, making it hard for data science or computer science students, or professionals, to efficiently learn the mathematics. This self-contained textbook bridges the gap between mathematical and machine learning texts, introducing the mathematical concepts with a minimum of prerequisites. It uses these concepts to derive four central machine learning methods: linear regression, principal component analysis, Gaussian mixture models and support vector machines. For students and others with a mathematical background, these derivations provide a starting point to machine learning texts. For those learning the mathematics for the first time, the methods help build intuition and practical experience with applying mathematical concepts. Every chapter includes worked examples and exercises to test understanding. Programming tutorials are offered on the book's web site.

The Russian Way of War
Author: Lester W. Grau
Publisher: Mentor Military
ISBN: 9781940370194
Category : History
Languages : en
Pages : 0
Book Description
Force Structure, Tactics, and Modernization of the Russian Ground Forces The mighty Soviet Army is no more. The feckless Russian Army that stumbled into Chechnya is no more. Today's Russian Army is modern, better manned, better equipped and designed for maneuver combat under nuclear-threatened conditions. This is your source for the tactics, equipment, force structure and theoretical underpinnings of a major Eurasian power. Here's what the experts are saying: "A superb baseline study for understanding how and why the modern Russian Army functions as it does. Essential for specialist and generalist alike." -Colonel (Ret) David M. Glantz, foremost Western author on the Soviet Union in World War II and Editor of The Journal of Slavic Military Studies. "Congratulations to Les Grau and Chuck Bartles on filling a gap which has yawned steadily wider since the end of the USSR. Their book addresses evolving Russian views on war, including the blurring of its nature and levels, and the consequent Russian approaches to the Ground Forces' force structuring, manning, equipping, and tactics. Confidence is conferred on the validity of their arguments and conclusions by copious footnoting, mostly from an impressive array of primary sources. It is this firm grounding in Russian military writings, coupled with the authors' understanding of war and the Russian way of thinking about it, that imparts such an authoritative tone to this impressive work." -Charles Dick, former Director of the Combat Studies Research Centre, Senior Fellow at the Defence Academy of the United Kingdom, author of the 1991 British Army Field Manual, Volume 2, A Treatise on Soviet Operational Art and author of From Victory to Stalemate The Western Front, Summer 1944 and From Defeat to Victory, The Eastern Front, Summer 1944. "Dr. Lester Grau's and Chuck Bartles' professional research on the Russian Armed Forces is widely read throughout the world and especially in Russia. Russia's Armed Forces have changed much since the large-scale reforms of 2008, which brought the Russian Army to the level of the world's other leading armies. The speed of reform combined with limited information about their core mechanisms represented a difficult challenge to the authors. They have done a great job and created a book which could be called an encyclopedia of the modern armed forces of Russia. They used their wisdom and talents to explore vital elements of the Russian military machine: the system of recruitment and training, structure of units of different levels, methods and tactics in defense and offence and even such little-known fields as the Arctic forces and the latest Russian combat robotics." -Dr. Vadim Kozyulin, Professor of Military Science and Project Director, Project on Asian Security, Emerging Technologies and Global Security Project PIR Center, Moscow. "Probably the best book on the Russian Armed Forces published in North America during the past ten years. A must read for all analysts and professionals following Russian affairs. A reliable account of the strong and weak aspects of the Russian Army. Provides the first look on what the Russian Ministry of Defense learned from best Western practices and then applied them on Russian soil." -Ruslan Pukhov, Director of the Moscow-based Centre for the Analysis of Strategies and Technologies (CAST) and member of the Public Council of the Russian Federation Ministry of Defense. Author of Brothers Armed: Military Aspects of the Crisis in Ukraine, Russia's New Army, and The Tanks of August.
