Statistical modeling: the two cultures (with comments and a rejoinder by the author)

Statistical Science, Vol. 16, No. 3. (August 2001), pp. 199-231,


There are two cultures in the use of statistical modeling to reach conclusions from data. One assumes that the data are generated by a given stochastic data model. The other uses algorithmic models and treats the data mechanism as unknown. The statistical community has been committed to the almost exclusive use of data models. This commitment has led to irrelevant theory, questionable conclusions, and has kept statisticians from working on a large range of interesting current problems. Algorithmic modeling, both in ...


Speed/accuracy trade-offs for modern convolutional object detectors

In 2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR 2017) (2017), pp. 7310-7319,


The goal of this paper is to serve as a guide for selecting a detection architecture that achieves the right speed/memory/accuracy balance for a given application and platform. To this end, we investigate various ways to trade accuracy for speed and memory usage in modern convolutional object detection systems. A number of successful systems have been proposed in recent years, but apples-to-apples comparisons are difficult due to different base feature extractors (e.g., VGG, Residual Networks), different default image resolutions, as well as different hardware and software platforms. We ...


Re-evaluation of MODIS MCD43 Greenland albedo accuracy and trends

Remote Sensing of Environment, Vol. 138 (November 2013), pp. 199-214,
Keywords: accuracy   albedo   greenland   mcd43   modis   remote-sensing  


[Highlights] [::] The MODIS 16-day snow albedo product is in general agreement with Greenland in situ data. [::] Analysis from 2000 to 2012 reveals negative trends leading to enhanced absorption of solar energy. [::] In 2012, albedo anomalies were more than two standard deviations below the 2000–2009 mean. [Abstract] In this study, the accuracy of the MODerate resolution Imaging Spectroradiometer (MODIS) combined Terra (MOD) and Aqua (MYD) 16-day albedo product (MCD43) is evaluated through comparisons with eleven years of in situ measurements at 17 automatic weather ...


Accuracy assessment of a remote sensing-based, pan-European forest cover map using multi-country national forest inventory data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Vol. 6, No. 1. (February 2013), pp. 54-65,


A pan-European forest cover map (FMAP2006) was produced using a novel automated classification approach using remotely sensed data from fine resolution satellite instruments. In contrast to previous classification accuracy assessments of such continental scale land cover products, the current study aimed for a reliable assessment at different geographical levels: pan-European, regional and local level. A unique data set consisting of detailed field inventory plots was provided via a collaboration with the national forest inventories (NFIs) in Europe. Close to 900,000 field ...

Combined Global Surface Summary of Day and European Climate Assessment and Dataset daily meteorological data sets (around 9000 stations) were used to build spatio-temporal geostatistical models and predict daily air temperature at ground resolution of 1 km for the global land mass. Predictions in space and time were made for the mean, maximum, and minimum temperatures using spatio-temporal regression-kriging with a time series of Moderate Resolution Imaging Spectroradiometer (MODIS) 8 day images, topographic layers (digital elevation model and topographic wetness index), and ...


The drama of uncertainty

Climatic Change In Climatic Change, Vol. 100, No. 1. (1 May 2010), pp. 77-85,


[Excerpt] Concluding remarks. We do not have consensus among stakeholders/decision makers, climate scientists, and social scientists on the relative importance of reducing uncertainty about future regional climate change for decision making. And we may never have such consensus. In this regard we are faced with an instance of meta-deep uncertainty. While it makes sense that there may be different perspectives on this issue based on what aspect of regional adaptation to climate change one is considering, it is also clear that perspectives are still too far apart. ...


Finding the right pixel size

Computers & Geosciences, Vol. 32, No. 9. (November 2006), pp. 1283-1298,


This paper discusses empirical and analytical rules to select a suitable grid resolution for output maps and based on the inherent properties of the input data. The choice of grid resolution was related with the cartographic and statistical concepts: scale, computer processing power, positional accuracy, size of delineations, inspection density, spatial autocorrelation structure and complexity of terrain. These were further related with the concepts from the general statistics and information theory such as Nyquist frequency concept from signal processing and equations ...


User Manual for the JRC Land Cover/Use Change Validation Tool

EUR - Scientific and Technical Research, Vol. 24683 (2011), pp. 1-23,


The JRC TREES-3 project aims at estimating forest cover changes at continental and regional levels for the tropical belt for the periods 1990-2000 and 2000-(2005)-2010 based on a systematic sample of forest cover change maps. An operational system has been developed for the processing and change assessment of a large data set of multi-temporal medium resolution imagery (sample units of 20 km x 20 km size analysed from with Landsat imagery). The main task is to assess as accurately as possible ...


Assessment of the adequacy of mathematical models

Agricultural Systems, Vol. 89, No. 2-3. (September 2006), pp. 225-247,


Models are mathematical representations of mechanisms that govern natural phenomena that are not fully recognized, controlled, or understood. They have become indispensable tools via decision support systems for policy makers and researchers to provide ways to express the scientific knowledge. Model usefulness has to be assessed through its sustainability for a particular purpose. Adequate statistical analysis is an indispensable step during development, evaluation, and revision phases of a model. Therefore, in this paper we discussed and compared several techniques to evaluate ...

Identifying strengths and limitations of pan-European forest cover maps through spatial comparison

International Journal of Geographical Information Science, Vol. 25, No. 11. (21 October 2011), pp. 1865-1884,


Detailed and harmonized information on spatial forest distribution is an essential input for forest-related environmental assessments, in particular, for biomass and growing stock modeling. In the last years, several mapping approaches have been developed in order to provide such information for Europe in a harmonized way. Each of these maps exhibits particular properties and varies in accuracy. Yet, they are often used in parallel for different modeling purposes. A detailed spatial comparison seemed necessary in order to provide information on the ...


Practical Implications of Design-Based Sampling Inference for Thematic Map Accuracy Assessment

Remote Sensing of Environment, Vol. 72, No. 1. (April 2000), pp. 35-45,


Sampling inference is the process of generalizing from sample data to make statements or draw conclusions about a population. Design-based inference is the inferential framework commonly invoked when sampling techniques are used in thematic map accuracy assessment. The conceptual basis of design-based inference is described, followed by discussion of practical implications of design-based inference, including (1) the population to which the inferences apply, (2) estimation formulas and their justification, (3) interpretation of accuracy measures, (4) representation of variability, (5) effect of ...

Free European data on forest distribution: overview and evaluation

Journal of Forest Science, Vol. 59, No. 11. (2013), pp. 447-457


A growing need for the evaluation of prospects and sustainability of forest resources calls for the availability of harmonized data on forest distribution. We described and evaluated nine datasets providing such information: Corine LandCover, four European forest maps and four tree species distribution maps. Apart from providing a condensed overview of these datasets, we focused on the match between selected forest maps and forest management plans (FMPs) of Slovakia, which can be thought of as highly accurate information on forest distribution. ...


Measuring the accuracy of species distribution models: a review

In 18th World IMACS Congress and MODSIM09 International Congress on Modelling and Simulation (July 2009), pp. 4241-4247


Species distribution models (SDMs) are empirical models relating species occurrence to environmental variables based on statistical or other response surfaces. Species distribution modeling can be used as a tool to solve many theoretical and applied ecological and environmental problems, which include testing biogeographical, ecological and evolutionary hypotheses, assessing species invasion and climate change impact, and supporting conservation planning and reserve selection. The utility of SDM in real world applications requires the knowledge of the model's accuracy. The accuracy of a model ...


Assessing the accuracy of land cover change with imperfect ground reference data

Remote Sensing of Environment, Vol. 114, No. 10. (19 October 2010), pp. 2271-2285,


The ground data used as a reference in the validation of land cover change products are often not an ideal gold standard but degraded by error. The effects of ground reference data error on the accuracy of land cover change detection and the accuracy of estimates of the extent of change were evaluated. Twelve data sets were simulated to allow the exploration of the impacts of a spectrum of ground data imperfections on the estimation of the producer's and user's accuracy ...
