The Sentimental Factor:Improving Review Classification via Human-Provided Information
Sentimental Factor Review Classification Human-Provided Information
2015/8/21
Sentiment classification is the task of labeling a review document according to the polarity of its prevailing opinion (favorable or unfavorable). In approaching this problem, a model builder often ha...
Improving Random Projections Using Marginal Information
Random Projections Marginal Information
2015/8/21
We present an improved version of random projections that takes advantage of marginal norms. Using a maximum likelihood estimator (MLE), marginconstrained random projections can improve estimation acc...
Improving accuracy and power with transfer learning using a meta-analytic database
Meta-analysis,fMRI,multiple comparison,machine learning
2012/11/23
Typical cohorts in brain imaging studies are not large enough for systematic testing of all the information contained in the images. To build testable working hypotheses, investigators thus rely on an...
Improving power posterior estimation of statistical evidence
Marginal likelihood Markov chain Monte Carlo Power posteriors Statistical evidence Tempering Thermo dynamic integration
2012/11/22
The statistical evidence (or marginal likelihood) is a key quantity in Bayesian statistics, allowing one to assess the probability of the data given the model under investigation. This paper focuses o...
Self-improving properties for abstract Poincaré type inequalities
Self-improving properties BMO and Lipschitz spaces John-Nirenberg inequalities generalized Poincare-Sobolev inequalities
2011/9/2
Abstract: We study self-improving properties in the scale of Lebesgue spaces of generalized Poincar\'e inequalities in the Euclidean space. We present an abstract setting where oscillations are given ...
Improving random number generators by chaotic iterations. Application in data hiding
Chaotic sequences Topological chaos Pseudorandom random number generator
2010/12/28
In this paper, a new pseudo-random number generator (PRNG) based on chaotic iterations is proposed. This method also combines the digits of two XORshifts PRNGs.
Improving PPM Algorithm Using Dictionaries
Text compression Markov model PPM Dictionary model
2011/2/22
We propose a method to improve traditional character-based PPM text compression algorithms. Consider a text file as a sequence of alternating words and non-words, the basic idea of our algorithm is to...
Improving efficiency scores of inefficient units with restricted primary resources
data envelopment analysis reallocation
2010/9/17
An important issue in Data Envelopment Analysis (DEA) is finding the efficiency scores of Decision Making Units (DMUs). For improving the efficiency scores of inefficient units, it is important to con...

An Inequality Improving the First Hermite-Hadamard Inequality for Convex Functions Defined on Linear Spaces and Applications for Semi-Inner Products
Hermite-Hadamard integral inequality Convex functions Semi-Inner Products
2008/7/2
An integral inequality for convex functions defined on linear spaces is obtained which contains in a particular case a refinement for the first part of the celebrated Hermite-Hadamard inequality. Appl...
