Jun 24, 2012 - Abstract: The success of machine learning algorithms generally depends on data representation, and we hypothesize that this is because different representations can entangle and hide more or less the different explanatory factors of variation behind the data. Almost no one is thinking about 'how to program in the language of OpenCog' even though it has the potential of far surpassing any of the existing probabilistic programming languages out there. Apr 12, 2013 - Generative models provide a probabilistic model of the predictors, here the words w, and the categories z, whereas discriminative models only provide a probabilistic model of the categories z given the words w. Mar 24, 2013 - If I had a hypergraph re-writing system, than I would have a place where I could unify natural language processing, logical reasoning and machine learning, all in one place. Although This paper reviews recent work in the area of unsupervised feature learning and deep learning, covering advances in probabilistic models, auto-encoders, manifold learning, and deep networks. Jan 22, 2014 - These assessments represent the unweighted average of probabilistic forecasts from three separate models trained on country-year data covering the period 1960-2011. Jun 10, 2013 - In their paper, "Montague Meets Markov: Deep Semantics with Probabilistic Logical Form," presented at the Second Joint Conference on Lexical and Computational Semantics (STARSEM2013) in June, Erk, Mooney and colleagues announced There is a common saying in the machine-learning world that goes: "There's no data like more data. Fortunately in recent years Machine Learning folks discovered Bayes and are now doing loads of interesting work with properly probabilistic models. I'm struggling with getting a unified view, from all perspectives. A machine-learning technique (see here) applied to all of the variables used in the two previous models, plus a few others of possible relevance, using the 'randomforest' package in R. Political economy makes particle physics look easy, if put in the proper perspective! Ng's (Stanford) youtube lectures in machine learning .) The algorithmic machine learning paradigm is in great contrast to the traditional probabilistic approaches of 'data modeling' in which I had been groomed both as an undergraduate and in graduate school. In these terms, the goal of most “machine learning” applications is to maximize (regularized/penalized) likelihood on the training corpus, or sometimes with respect to a held-out corpus if there are unmodeled parameters such as quantity of regularization. For a slightly different perspective on this you might want to watch http://videos.syntience.com/ai-meetups/smamfm.html . Jan 1, 2014 - To understand learning of parameters for probabilistic graphical models  To understand actions and decisions with Kevin P. Deterministic and hence would almost inevitably overfit the data unless the real-world variation really was tiny. This both because matters become more technological (by accident) and because the systems are more complicated. Murphy, “Machine Learning: A Probabilistic Perspective”, MIT Press, 2012. Jan 29, 2011 - It gives perspective and context to anyone that may attempt to learn to use data mining software such as SAS Enterprise Miner or who may take a course in machine learning (like Dr.
