Long-Term Probabilistic Forecast of Vegetation Conditions Using Climate Attributes in the Four Corners Region
McPhillips, Erika, Lee, Hyeongseong, Xie, Xiangyu, Baylis, Kathy, Funk, Chris, Gu, Mengyang
Weather conditions can drastically alter the state of crops and rangelands, and in turn, impact the incomes and food security of individuals worldwide. Satellite-based remote sensing offers an effective way to monitor vegetation and climate variables on regional and global scales. The annual peak Normalized Difference Vegetation Index (NDVI), derived from satellite observations, is closely associated with crop development, rangeland biomass, and vegetation growth. Although various machine learning methods have been developed to forecast NDVI over short time ranges, such as one-month-ahead predictions, long-term forecasting approaches, such as one-year-ahead predictions of vegetation conditions, are not yet available. To fill this gap, we develop a two-phase machine learning model to forecast the one-year-ahead peak NDVI over high-resolution grids, using the Four Corners region of the Southwestern United States as a testbed. In phase one, we identify informative climate attributes, including precipitation and maximum vapor pressure deficit, and develop the generalized parallel Gaussian process that captures the relationship between climate attributes and NDVI. In phase two, we forecast these climate attributes using historical data at least one year before the NDVI prediction month, which then serve as inputs to forecast the peak NDVI at each spatial grid. We developed open-source tools that outperform alternative methods for both gross NDVI and grid-based NDVI one-year forecasts, providing information that can help farmers and ranchers make actionable plans a year in advance.

Uncertainty-aware Bayesian machine learning modelling of land cover classification
Bilson, Samuel, Pustogvar, Anna
Land cover classification involves the production of land cover maps, which determine the type of land through remote sensing imagery. Over recent years, such classification is being performed by machine learning classification models, which can give highly accurate predictions on land cover per pixel using large quantities of input training data. However, such models do not currently take account of input measurement uncertainty, which is vital for traceability in metrology. In this work we propose a Bayesian classification framework using generative modelling to take account of input measurement uncertainty. We take the specific case of Bayesian quadratic discriminant analysis, and apply it to land cover datasets from Copernicus Sentinel-2 in 2020 and 2021. We benchmark the performance of the model against more popular classification models used in land cover maps such as random forests and neural networks. We find that such Bayesian models are more trustworthy, in the sense that they are more interpretable, explicitly model the input measurement uncertainty, and maintain predictive performance of class probability outputs across datasets of different years and sizes, whilst also being computationally efficient.

Fuzzy Temporal Protoforms for the Quantitative Description of Processes in Natural Language
Fontenla-Seco, Yago, Bugarín-Diz, Alberto, Lama, Manuel
In this paper, we propose a series of fuzzy temporal protoforms in the framework of the automatic generation of quantitative and qualitative natural language descriptions of processes. The model includes temporal and causal information from processes and attributes, quantifies attributes in time during the process life-span and recalls causal relations and temporal distances between events, among other features. Through integrating process mining techniques and fuzzy sets within the usual Data-to-Text architecture, our framework is able to extract relevant quantitative temporal as well as structural information from a process and describe it in natural language involving uncertain terms. A real use-case in the cardiology domain is presented, showing the potential of our model for providing natural language explanations addressed to domain experts.

Top 10 Data Innovation Trends During 2020
If I were to choose what was hottest trend in 2020, it would not be a single item in this top 10 list. The hottest trend would be a hybrid (convergence) of several of these items. That hybrid would include: Observability, coupled with Edge and the ever-rising ubiquitous IoT (sensors on everything), boosted by 5G and cloud technologies, fueling ever-improving ML and DL algorithms, all of which are enabling "just-in-time" intelligence and intelligent automation (for data-driven decisions and action, at the point of data collection), deployed with a data-literate workforce, in a sustainable and trusted MLOps environment, where algorithms, data, and applications work harmoniously and are governed and secured by AIOps. If we learned anything from the year 2020, it should be that trendy technologies do not comprise a menu of digital transformation solutions to choose from, but there really is only one combined solution, which is the hybrid convergence of data innovation technologies. From my perspective, that was the single most significant data innovation trend of the year 2020.
