IntroductiontoMachineLearning
From: VideoLectures on Fri, Apr 01 2011 7:21 AM
This talk gives an overview of machine learning from a practical perspective. Starting with examples of problems we might want to solve (in vision, signal processing, and geospatial inference), and the assumptions we have to make in order to get anywhere, it then covers a number of different sup...

SemanticTechnologiesOriginsLinkedDataandBeyond
From: VideoLectures on Fri, Apr 01 2011 7:21 AM
In this talk, Barry Norton gives an introduction to the semantic technologies that are applied in many of the approaches presented in the bootcamp. The emphasis is on the technologies applied in Linked Data and in associated lightweight APIs and services. Particular attention is paid to aspects ...

DataminingandMachinelearningalgorithms
From: VideoLectures on Fri, Apr 01 2011 7:21 AM
The purpose of these lectures today is to review a few rather basic Machine Learning algorithms, while trying to see them from a Data Mining perspective. Thus, we will discuss the very notion of modelling, its role within the process of Knowledge Discovery from Data, and some of the particularit...

DirectedGraphicalModels
From: VideoLectures on Fri, Apr 01 2011 7:20 AM
In this talk I introduce the basic concepts of directed graphical models. I then introduce the EM algorithm and discuss learning in latent variable models, considering several mixture models (discrete latent variables), probabilistic PCA (continuous latent variables) and extensions. Next, I desc...

IntroductiontoMachineTranslation
From: VideoLectures on Fri, Apr 01 2011 7:19 AM
Machine Translation has evolved notably in the last two decades. This talk introduces the main concepts related to Machine Translation. First, IBM word alignment models are described. Then, phrase-based models are explained as a natural extension of word alignment models. Finally, syntactic appr...

ThrottlingPoissonProcesses
From: VideoLectures on Mon, Mar 28 2011 7:31 PM
We study a setting in which Poisson processes generate sequences of decision-making events. The optimization goal is allowed to depend on the rate of decision outcomes; the rate may depend on a potentially long backlog of events and decisions. We model the problem as a Poisson process with a thro...

Domaanalogavmestnemparku
From: VideoLectures on Mon, Mar 28 2011 7:30 PM
Učenci dobijo nalogo o reformaciji. Na poti domov skozi mestni park, si želijo, da bi kipi, ki predstavljajo to obdobje, oživeli in jim povedali kaj o sebi. Ali se lahko take sanje uresničijo?

MultilingualDiscoveryinEuropeana
From: VideoLectures on Mon, Mar 28 2011 7:30 PM
Multilingual Information Access is not difficult, just very expensive. Not development cost, but maintenance cost are the real bottleneck. Multilingual Information Access is all about resources and little about technology. Be extremely explicit in what you are going to offer and be certain that ...

OnlineLearninginTheManifoldofLowRankMatrices
From: VideoLectures on Mon, Mar 28 2011 7:30 PM
When learning models that are represented in matrix forms, enforcing a low-rank constraint can dramatically improve the memory and run time complexity, while providing a natural regularization of the model. However, naive approaches for minimizing functions over the set of low-rank matrices are ...

ShadowDirichletforRestrictedProbabilityModeling
From: VideoLectures on Mon, Mar 28 2011 7:30 PM
Although the Dirichlet distribution is widely used, the independence structure of its components limits its accuracy as a model. The proposed shadow Dirichlet distribution manipulates the support in order to model probability mass functions (pmfs) with dependencies or constraints that often aris...
