Estimating future burned areas under changing climate in the EU-Mediterranean countries

  
Science of The Total Environment, Vol. 450-451 (April 2013), pp. 209-222, https://doi.org/10.1016/j.scitotenv.2013.02.014

Abstract

The impacts of climate change on forest fires have received increased attention in recent years at both continental and local scales. It is widely recognized that weather plays a key role in extreme fire situations. It is therefore of great interest to analyze projected changes in fire danger under climate change scenarios and to assess the consequent impacts of forest fires. In this study we estimated burned areas in the European Mediterranean (EU-Med) countries under past and future climate conditions. Historical ...

 

Random forests

  
Machine Learning, Vol. 45, No. 1. (2001), pp. 5-32, https://doi.org/10.1023/a%3a1010933404324

Abstract

Random forests are a combination of tree predictors such that each tree depends on the values of a random vector sampled independently and with the same distribution for all trees in the forest. The generalization error for forests converges a.s. to a limit as the number of trees in the forest becomes large. The generalization error of a forest of tree classifiers depends on the strength of the individual trees in the forest and the correlation between them. Using a random ...

Predicting habitat suitability with machine learning models: The potential area of Pinus sylvestris L. in the Iberian Peninsula

  
Ecological Modelling, Vol. 197, No. 3-4. (August 2006), pp. 383-393, https://doi.org/10.1016/j.ecolmodel.2006.03.015

Abstract

We present a modelling framework for predicting forest areas. The framework is obtained by integrating a machine learning software suite within the GRASS Geographical Information System (GIS) and by providing additional methods for predictive habitat modelling. Three machine learning techniques (Tree-Based Classification, Neural Networks and Random Forest) are available in parallel for modelling from climatic and topographic variables. Model evaluation and parameter selection are measured by sensitivity-specificity ROC analysis, while the final presence and absence maps are obtained through maximisation of ...

 

Does the interpolation accuracy of species distribution models come at the expense of transferability?

  
Ecography, Vol. 35, No. 3. (March 2012), pp. 276-288, https://doi.org/10.1111/j.1600-0587.2011.06999.x

Abstract

Model transferability (extrapolative accuracy) is one important feature in species distribution models, required in several ecological and conservation biological applications. This study uses 10 modelling techniques and nationwide data on both (1) species distribution of birds, butterflies, and plants and (2) climate and land cover in Finland to investigate whether good interpolative prediction accuracy for models comes at the expense of transferability – i.e. markedly worse performance in new areas. Models’ interpolation and extrapolation performance was primarily assessed using AUC (the ...

 

The Neighbor Search approach applied to reservoir optimal operation: the Hoa Binh case study

  
No. hal-00698200. (2006)

Abstract

[Conclusion] The focus of this thesis is to show, through a real-case application, how the NS can be useful to improve the decision-making process for multi-objectives reservoir operation planning. After a survey of the principal techniques employed in literature to solve such problems, the NS algorithm has been discussed. Further, the case-study has been presented. Hoa Binh is the largest reservoir in Vietnam, providing 40% of its total power supplies and protecting the capital Hanoi from major flooding events. This double purpose generates conflicts in its management ...

Neural Turing machines

  
(10 Dec 2014)

Abstract

We extend the capabilities of neural networks by coupling them to external memory resources, which they can interact with by attentional processes. The combined system is analogous to a Turing Machine or Von Neumann architecture but is differentiable end-to-end, allowing it to be efficiently trained with gradient descent. Preliminary results demonstrate that Neural Turing Machines can infer simple algorithms such as copying, sorting, and associative recall from input and output examples. ...

Sparse Algorithms Are Not Stable: A No-Free-Lunch Theorem

  
Pattern Analysis and Machine Intelligence, IEEE Transactions on, Vol. 34, No. 1. (January 2012), pp. 187-193, https://doi.org/10.1109/tpami.2011.177

Abstract

We consider two desired properties of learning algorithms: *sparsity* and *algorithmic stability*. Both properties are believed to lead to good generalization ability. We show that these two properties are fundamentally at odds with each other: a sparse algorithm cannot be stable and vice versa. Thus, one has to trade off sparsity and stability in designing a learning algorithm. In particular, our general result implies that $\ell_1$-regularized regression (Lasso) cannot be stable, while $\ell_2$-regularized regression is known to have strong stability properties ...

 

A survey of multiple classifier systems as hybrid systems

  
Information Fusion, Vol. 16 (March 2014), pp. 3-17, https://doi.org/10.1016/j.inffus.2013.04.006

Abstract

A current focus of intense research in pattern classification is the combination of several classifier systems, which can be built following either the same or different models and/or datasets building approaches. These systems perform information fusion of classification decisions at different levels overcoming limitations of traditional approaches based on single classifiers. This paper presents an up-to-date survey on multiple classifier system (MCS) from the point of view of Hybrid Intelligent Systems. The article discusses major issues, such as diversity and decision ...

 

Comparing and combining physically-based and empirically-based approaches for estimating the hydrology of ungauged catchments

  
Journal of Hydrology, Vol. 508 (January 2014), pp. 227-239, https://doi.org/10.1016/j.jhydrol.2013.11.007

Abstract

[Highlights] [::] Methods for estimating various hydrological indices at ungauged sites were compared. [::] Methods included a TopNet rainfall-runoff model and a Random Forest empirical model. [::] TopNet estimates were improved through correction using Random Forest estimates. [::] Random Forests provided the best estimates of all indices except mean flow. [::] Mean flow was best estimated using an already published empirical method. [Summary] Predictions of hydrological regimes at ungauged sites are required for various purposes such as setting environmental flows, assessing availability of water resources or ...

 

Shifts in Arctic vegetation and associated feedbacks under climate change

  
Nature Climate Change, Vol. 3, No. 7. (31 July 2013), pp. 673-677, https://doi.org/10.1038/nclimate1858

Abstract

Climate warming has led to changes in the composition, density and distribution of Arctic vegetation in recent decades1, 2, 3, 4. These changes cause multiple opposing feedbacks between the biosphere and atmosphere5, 6, 7, 8, 9, the relative magnitudes of which will have globally significant consequences but are unknown at a pan-Arctic scale10. The precise nature of Arctic vegetation change under future warming will strongly influence climate feedbacks, yet Earth system modelling studies have so far assumed arbitrary increases in shrubs ...

 

A statistical explanation of MaxEnt for ecologists

  
Diversity and Distributions, Vol. 17, No. 1. (1 January 2011), pp. 43-57, https://doi.org/10.1111/j.1472-4642.2010.00725.x

Abstract

MaxEnt is a program for modelling species distributions from presence-only species records. This paper is written for ecologists and describes the MaxEnt model from a statistical perspective, making explicit links between the structure of the model, decisions required in producing a modelled distribution, and knowledge about the species and the data that might affect those decisions. To begin we discuss the characteristics of presence-only data, highlighting implications for modelling distributions. We particularly focus on the problems of sample bias and lack ...

 

Knowledge discovery by accuracy maximization

  
Proceedings of the National Academy of Sciences, Vol. 111, No. 14. (24 April 2014), pp. 201220873-5122, https://doi.org/10.1073/pnas.1220873111

Abstract

[Significance] We propose an innovative method to extract new knowledge from noisy and high-dimensional data. Our approach differs from previous methods in that it has an integrated procedure of validation of the results through maximization of cross-validated accuracy. In many cases, this method performs better than existing feature extraction methods and offers a general framework for analyzing any kind of complex data in a broad range of sciences. Examples ranging from genomics and metabolomics to astronomy and linguistics show the versatility ...

 

Mapping land cover from detailed aerial photography data using textural and neural network analysis

  
International Journal of Remote Sensing, Vol. 28, No. 7. (1 April 2007), pp. 1625-1642, https://doi.org/10.1080/01431160600887722

Abstract

Automated mapping of land cover using black and white aerial photographs, as an alternative method to traditional photo?interpretation, requires using methods other than spectral analysis classification. To this end, textural measurements have been shown to be useful indicators of land cover. In this work, a neural network model is proposed and tested to map historical land use/land cover (LUC) from very detailed panchromatic aerial photographs (5 m resolution) using textural measurements. The method is used to identify different land use and management ...

 

Vulnerability of Pinus cembra L. in the Alps and the Carpathian mountains under present and future climates

  
Forest Ecology and Management, Vol. 259, No. 4. (05 February 2010), pp. 750-761, https://doi.org/10.1016/j.foreco.2009.10.001

Abstract

Proactive management should be applied within a forest conservation context to prevent extinction or degradation of those forest ecosystems that we suspect will be affected by global warming in the next century. The aim of this study is to estimate the vulnerability under climate change of a localized and endemic tree species Pinus cembra that occurs in the alpine timberline. We used the Random Forest ensemble classifier and available bioclimatic and ecological data to model present and future suitable areas for ...

 

Novel methods improve prediction of species' distributions from occurrence data

  
Ecography, Vol. 29, No. 2. (1 April 2006), pp. 129-151, https://doi.org/10.1111/j.2006.0906-7590.04596.x

Abstract

Prediction of species’ distributions is central to diverse applications in ecology, evolution and conservation science. There is increasing electronic access to vast sets of occurrence records in museums and herbaria, yet little effective guidance on how best to use this information in the context of numerous approaches for modelling distributions. To meet this need, we compared 16 modelling methods over 226 species from 6 regions of the world, creating the most comprehensive set of model comparisons to date. We used presence-only ...

 

The Need for Open Source Software in Machine Learning

  
J. Mach. Learn. Res., Vol. 8 (December 2007), pp. 2443-2466

Abstract

Open source tools have recently reached a level of maturity which makes them suitable for building large-scale real-world systems. At the same time, the field of machine learning has developed a large body of powerful learning algorithms for diverse applications. However, the true potential of these methods is not used, since existing implementations are not openly shared, resulting in software with low usability, and weak interoperability. We argue that this situation can be significantly improved by increasing incentives for researchers to ...

 

Batch mode reinforcement learning based on the synthesis of artificial trajectories

  
In Annals of Operations Research, Vol. 208, No. 1. (2013), pp. 383-416, https://doi.org/10.1007/s10479-012-1248-5

Abstract

In this paper, we consider the batch mode reinforcement learning setting, where the central problem is to learn from a sample of trajectories a policy that satisfies or optimizes a performance criterion. We focus on the continuous state space case for which usual resolution schemes rely on function approximators either to represent the underlying control problem or to represent its value function. As an alternative to the use of function approximators, we rely on the synthesis of “artificial trajectories” from the ...

A few useful things to know about machine learning

  
Commun. ACM, Vol. 55, No. 10. (October 2012), pp. 78-87, https://doi.org/10.1145/2347736.2347755

Abstract

Machine learning algorithms can figure out how to perform important tasks by generalizing from examples. This is often feasible and cost-effective where manual programming is not. As more data becomes available, more ambitious problems can be tackled. As a result, machine learning is widely used in computer science and other fields. However, developing successful machine learning applications requires a substantial amount of “black art” that is hard to find in textbooks. This article summarizes twelve key lessons that machine learning researchers ...

 

The rise and fall of supervised machine learning techniques

  
Bioinformatics, Vol. 27, No. 24. (15 December 2011), pp. 3331-3332, https://doi.org/10.1093/bioinformatics/btr585

Abstract

Machine learning is of immense importance in bioinformatics and biomedical science more generally (Larrañaga et al., 2006; Tarca et al., 2007). In particular, supervised machine learning has been used to great effect in numerous bioinformatics prediction methods. Through many years of editing and reviewing manuscripts, we noticed that some supervised machine learning techniques seem to be gaining in popularity while others seemed, at least to our eyes, to be looking ‘unfashionable’. ...

 

Q-learning

  
Machine Learning In Machine Learning, Vol. 8, No. 3-4. (1 May 1992), pp. 279-292, https://doi.org/10.1007/bf00992698
Keywords: machine-learning   q-learning  

Abstract

Q-learning (Watkins, 1989) is a simple way for agents to learn how to act optimally in controlled Markovian domains. It amounts to an incremental method for dynamic programming which imposes limited computational demands. It works by successively improving its evaluations of the quality of particular actions at particular states. This paper presents and proves in detail a convergence theorem for Q-learning based on that outlined in Watkins (1989). We show that Q-learning converges to the optimum action-values with probability 1 so long ...
