Fish survival prediction in an aquatic environment using random forest model

Abstract

In the real world, it is very difficult for fish farmers to select the perfect fish species for aquaculture in a specific aquatic environment. The main goal of this research is to build a machine learning that can predict the perfect fish species in an aquatic environment. In this paper, we have utilized a model using random forest (RF). To validate the model, we have used a dataset of aquatic environment for 11 different fishes. To predict the fish species, we utilized the different characteristics of aquatic environment including pH, temperature, and turbidity. As a performance metrics, we measured accuracy, true positive (TP) rate, and kappa statistics. Experimental results demonstrate that the proposed RF-based prediction model shows accuracy 88.48%, kappa statistic 87.11% and TP rate 88.5% for the tested dataset. In addition, we compare the proposed model with the state-of-art models J48, RF, k-nearest neighbor (k-NN), and classification and regression trees (CART). The proposed model outperforms than the existing models by exhibiting the higher accuracy score, TP rate and kappa statistics.

Transfer learning with fine-tuned deep CNN ResNet50 model for classifying COVID-19 from chest X-ray images

“…Confusion Matrix, Precision, Recall, F1 Score, and Accuracy are the standard evaluation method for the classification model. As the name suggests, the Confusion Matrix gives us a matrix as output and describes the complete performance of the model [58] . It has four terminologies including True Positive (TP), False Positive (FP), False Negative (FN), and True Negative (TN).…”

An internet of things framework for real-time aquatic environment monitoring using an Arduino and sensors

“…The range of pH value is 6.02-8.39, 8.57-8.87, 6.00-7.83, 6.51-8.30 and 3.84-3.95 for pond 1, pond 2, pond 3, pond 4, and pond 5, respectively. The pH range of pond 1 is suited for fish production according to the standard reference value, 6.5-8.5 [23]. The received pH value, 8.57-8.87 from pond 2 is greater than the ideal value.…”

Selecting goldfish broods use the weighted product and simple additive weighting methods

“…Attribute weight functions as a positive rating, while the cost attribute, including attribute ratings, functions negatively. This method uses multiplication as the attribute rating link, where the rating of each attribute must be increased first with the appropriate weight [1], [12], [19]- [24]. This process is the same as the normalization process.…”
