Handling Missing Data in Decision Trees: A Probabilistic Approach [article]

Pasha Khosravi, Antonio Vergari, YooJung Choi, Yitao Liang, Guy Van den Broeck
2020 arXiv   pre-print
Concurrently, missing data is a prevalent occurrence that hinders performance of machine learning models. As such, handling missing data in decision trees is a well studied problem.  ...  Decision trees are a popular family of models due to their attractive properties such as interpretability and ability to handle heterogeneous data.  ...  The authors would like to thank Steven Holtzen for initial discussions about expected prediction for decision trees.  ...

A compositional approach to probabilistic knowledge compilation

Giso H. Dal, Alfons W. Laarman, Arjen Hommersom, Peter J.F. Lucas
2021 International Journal of Approximate Reasoning  
However, these methods require a computationally intensive compilation step in search of these patterns, which effectively prohibits the handling of larger BNs.  ...  In this paper, we propose a solution to this problem by extending WMC methods with a framework called Compositional Weighted Model Counting (CWMC).  ...  Data locality plays a major role in performance. Quite simply, there are more cache misses for monolithic representations than there are for composed representations.  ...

EntropyDB: A Probabilistic Approach to Approximate Query Processing [article]

Laurel Orr, Magdalena Balazinska, Dan Suciu
2019 arXiv   pre-print
We present EntropyDB, an interactive data exploration system that uses a probabilistic approach to generate a small, query-able summary of a dataset.  ...  Departing from traditional summarization techniques, we use the Principle of Maximum Entropy to generate a probabilistic representation of the data that can be used to give approximate query answers.  ...  Sketches have the benefit of being able to handle streaming data but are usually built to handle a limited number of queries.  ...

Probabilistic DL Reasoning with Pinpointing Formulas: A Prolog-based Approach

2019 Theory and Practice of Logic Programming  
To this purpose, we introduced a probabilistic semantics, named DISPONTE, in order to combine description logics (DLs) with probability theory.  ...  The probability of a query can be then computed from the set of its explanations by building a Binary Decision Diagram (BDD).  ...  Example 8 Consider, for example, the rule ∃ defined as ({(x : ∃S.C), miss(z, {(x, z) : S, z : C})}, {}) → {{anon(y), ((x, y) : S), (y : C)}} handling existential restrictions.  ...

Acknowledgements There are many people to which I am indebted during this last step in my seemingly life-long journey as a student! Foremost, I would like to thank my advisor Daniel.  ...  Big thank you to Iacopo and Corinne who helped us in many ways and showed us some special places in Switzerland.  ...  The TM approach predicts missing location data as well as the PD approach, however, our approach outperforms the PD method for predicting missing proximity data.  ...

A probabilistic graphical model approach in 30 m land cover mapping with multiple data sources [article]

Jie Wang, Luyan Ji, Xiaomeng Huang, Haohuan Fu, Shiming Xu, Congcong Li
2016 arXiv   pre-print
A probabilistic graphical model (PGM) approach is proposed in this research for 30 m resolution land-cover mapping with multi-temporal Landsat and MODerate Resolution Imaging Spectroradiometer (MODIS)  ...  Independent classifiers were applied to two single-date Landsat 8 scenes and the MODIS time-series data, respectively, for probability estimation. A PGM was created for each pixel in Landsat 8 data.  ...  RF is an ensemble classifier that consists of multiple decision trees. It can maintain accuracy when missing values exist (Rodriguez-Galiano, Ghimire, et al. 2012; ).  ...

Probabilistic Forecasting of Surface Ozone with a Novel Statistical Approach

Nikolay V. Balashov, Anne M. Thompson, George S. Young
2017 Journal of Applied Meteorology and Climatology  
In this way, when a regression is developed for a specific regime, data from the other regimes are also used, with weights based on their similarity to this specific regime.  ...  This approach, regression in SOM (REGiS), yields a distinct model for each regime taking into account both the training cases for that regime and other similar training cases.  ...  Using various meteorological variables, the CART method generates a decision tree with a number of categories, which represent various modes of ozone pollutionsome are polluted, some are moderate, and  ...

A probabilistic and decision-theoretic approach to the management of infectious disease at the ICU

Peter J.F. Lucas, Nicolette C. de Bruijn, Karin Schurink, Andy Hoepelman
2000 Artificial Intelligence in Medicine  
In this paper, we describe the development of a probabilistic and decision-theoretic system that aims to assist clinicians in diagnosing and treating patients with pneumonia in the intensive-care unit.  ...  The patient data that were available were of limited value in the initial construction of the models because of problems of incompleteness. In particular, detailed temporal information was missing.  ...  Moreover, these systems offer a natural environment for facilities of decision support that assist clinicians in handling hard clinical problems. The reasons for this are twofold: 1.  ...

2019 IEEE Access  
In this paper, a new process learning framework that is based on probabilistic learning and predicate logic is proposed.  ...  This paper targets a methodology of learning processes given data and the learning algorithm finds out the logical operators that bind the events described in data and model it using predicate logic.  ...  Though this approach provides great control to the user, the user needs to control the mechanism for handling the data flow.  ...
