Building Suitable Datasets for Soft Computing and Machine Learning Techniques from Meteorological Data Integration: A Case Study for Predicting Significant Wave Height and Energy Flux

Abstract

Meteorological data are extensively used to perform environmental learning. Soft Computing (SC) and Machine Learning (ML) techniques represent a valuable support in many research areas, but require datasets containing information related to the topic under study. Such datasets are not always available in an appropriate format and its preparation and pre-processing implies a lot of time and effort by researchers. This paper presents a novel software tool with a user-friendly GUI to create datasets by means of management and data integration of meteorological observations from two data sources: the National Data Buoy Center and the National Centers for Environmental Prediction and for Atmospheric Research Reanalysis Project. Such datasets can be created using buoys and reanalysis data through customisable procedures, in terms of temporal resolution, predictive and objective variables, and can be used by SC and ML methodologies for prediction tasks (classification or regression). The objective is providing the research community with an automated and versatile system for the casuistry that entails well-formed and quality data integration, potentially leading to better prediction models. The software tool can be used as a supporting tool for coastal and ocean engineering applications, sustainable energy production, or environmental modelling; as well as for decision-making in the design and building of coastal protection structures, marine transport, ocean energy converters, and well-planned running of offshore and coastal engineering activities. Finally, to illustrate the applicability of the proposed tool, a case study to classify waves depending on their significant height and to predict energy flux in the Gulf of Alaska is presented.

Artificial intelligence an enabler for sustainable engineering decision-making in uncertain environment: a review and future propositions

“…The emotional neural network helped in modelling the hourly river flow contributing to the water resource monitoring and river engineering sustainability. Furthermore, machine learning algorithms helped in developing sustainable dams and addressing other problems related to coastal and ocean engineering (G omez-Orellana et al, 2021). Another interesting topic reviewed with respect to SE is resource utilization for sustainability.…”

“…Machine learning techniques showed meaningful understandings for water assets management, fulfilling the research in SE with respect to water dam research (Yahya et al , 2020). Considering meteorological data required to operate environmental learning, machine learning techniques significantly predict energy flux and significant wave height (Gómez-Orellana et al , 2021). Gómez-Orellana et al (2021) discussed the importance of software tools based on machine learning to address the problems related to ocean and coastal engineering, sustainable energy manufacturing and environmental modelling, which helps enhance SE.…”

“…This module can be evaluated by measuring the response time defined as the time taken between sending a request to the server and the task completion [93]. Response time is the most appropriate evaluation metric to evaluate analytics latency and system availability [94]. 3) Data Consistency Handler: In this module, diverse data manipulation procedures are applied on the inconsistent IoT data, such as noisy data cleansing and filtering, depending on the data type and system purpose.…”

Analyzing the effectiveness of MEMS sensor and IoT in predicting wave height using machine learning models

“…In coastal and offshore engineering, the prediction of wave parameters is an essential topic. A variety of models and methodologies have been used for wave height prediction, such as artificial neural networks (ANN) [12,13], adaptive neuro-fuzzy inference systems [14,15], and other soft computing technologies [16] have been recognized as novel approaches for developing intelligent systems, and related approaches have been utilized to predict wave height characteristics. Machine learning (ML) is also a unique approach to predict wave heights.…”
