This is particularly important for the Foreign Exchange (Forex) market owing to its high volatility which is affected by both internal and external market factors. Volatility is considered to be one of the significant obstacles for accurate directional prediction in the forex market. Although research efforts have been made to couple dynamic volatility with trend prediction models, most previous studies have been conducted subjected to unrealistic assumptions pertaining to volatility which have led to unsatisfactory results. This indicates that traders still face serious challenges when deriving more accurate predictions on the direction of the forex market, in order to remain profitable in the market. This study presents a directional prediction model for the forex market incorporating the dynamic volatility inherent to the market using intraday data. This was achieved by identifying different volatility levels that exist in the market using techniques such as change point analysis and clustering while Support Vector Machines (SVMs) are utilized to capture the directional movement of the market. The proposed solution is validated using different metrics and the results indicate that it outperforms the standard trend prediction method subjected to the nature of the input variables used when constructing the SVM models.","PeriodicalId":308901,"journal":{"name":"2022 6th SLAAI International Conference on Artificial Intelligence (SLAAI-ICAI)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127791590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we tackle the problem of determining the entry and exit points for firefighting Unmanned Aerial Vehicles (UAVs) when approaching and leaving the wildfire zone. The entry and exit point are scored based on the time the UAVs spend in the fire zone and the time to reach the fire zone. The problem is formulated as a regression model, which is tackled using machine learning algorithms, namely decision trees and random forest. The methods are simulated and evaluated on synthetic data, and the results show that the approach was able to provide accurate rankings of the entry and exit points.","PeriodicalId":308901,"journal":{"name":"2022 6th SLAAI International Conference on Artificial Intelligence (SLAAI-ICAI)","volume":"390 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131506371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant identification and disease classification are two major agricultural research areas, focusing on introducing computerized systems rather than manual methods. Many researchers used various identification and classification techniques using computer-based systems as human classification errors lead to risk and high cost. Medicinal plant identification needs an expert to correctly identify plants because misidentifying poisonous plants as medicinal plants causes fatal cases. Further, taking diseased medicinal plants to prepare medicines and herbal products may have adverse effects. Therefore, this study proposed a computerized method to identify medicinal plants and classify their diseases to overcome such shortcomings. In this work, a comparison is done with Convolutional Neural Network (CNN) architecture from scratch and Transfer Learning with several experiments.

Most of these ADAS are vision-based and in order to operate them properly, these systems require a clear vision which is challenging to acquire during the night. Considering this limitation, the study presented explores the possibility of translating night-time images to clear and visible day-time images which can be used for ADAS instead of poor-quality night-time images. Even though there exist many deep-learning-based techniques to transform images between two domains, most of them highly depend on pixel-to-pixel paired datasets during training. It is challenging to develop such a dataset, particularly in dynamic roadside environments. Hence, this study proposes unsupervised deep learning with the popular Cycle-GAN model to cater the problem. Another challenging task is accessing the quality of the Cycle-GAN generated images. Since there do not exist pixel-to-pixel paired images, to compare the quality of the regenerated images, Blind Referenceless Image Spatial Quality Evaluator (BRISQUE), a referenceless image quality evaluation technique, is utilised to evaluate the performance of the model. The synthesized output of the trained Cycle-GAN indicated an average BRISQUE score of 28.0416, whereas that of the original day-time images was 26.2156. This exhibits that the Cycle-GAN was able to generate synthesised day-time images with unpaired night images with significant similarity to the actual day-time images.

Emergency vehicles happen to wait at signalized intersections with fixed cycle timing.

In online interviews the candidate faces the interview panel virtually, limiting the opportunity of the panel to observe facial expressions, body language and other soft skills of the candidate. Analyzing the required soft skills and attitudes for a particular job is a good parameter in the long term to judge the suitability of a candidate to hold on for the job. Yet, selecting the most suitable candidate who is good ‘on paper’ as well as good ‘in person’ is very challenging. This research proposes a method of identifying emotions of candidates based on a captured video sequence of the candidate during the interview. Finally the developed model will be able to calculate the most prevalent emotion of the candidate during the interview. Thus, it is expected that fine-grained speaker-specific continuous emotion recognition system developed in this research will help online interview panels to select the most suitable candidate by giving extra information about the candidates in online interviews. The system consists of four main modules for image preprocessing, feature extraction, identification of feature occurrences and intensities and classification of emotions. The system is capable of classifying the emotions with 68% accuracy using the Mini_Xception method. The model can be further improved by having a uniform training data set, which is a challenge. As future work it was identified to develop a prediction model for the suitability of each candidate for the advertised post.","PeriodicalId":308901,"journal":{"name":"2022 6th SLAAI International Conference on Artificial Intelligence (SLAAI-ICAI)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115909208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sri Lanka is well renowned for production of quality rubber. This study is undertaken to forecast natural rubber (NR) prices for upcoming years in Sri Lanka. Since rubber is a storable intermediate good, current population heavily depends on future prices. Before the year 2011, rubber has good price scale, but due to the lack of government intervention the rubber price has been decreased after 2011. With change of rubber price, the accurate forecast is extremely important in executing policies and making decisions for the future of rubber industry. Moreover, there is no research studies can be found which attempts to forecast monthly NR prices in Sri Lanka by using machine learning techniques. Monthly rubber prices from June 2005 to January 2019 was considered for this study. 80% of the data was used to fit the model and the rest was used for model performance evaluation. All the unit root tests confirmed that the first difference of log series was stationary. ARIMA (1,1,1) model was selected as the best model with lower Akaike Information Criterion (AIC) among the other candidate models which exhibits RMSE of 22.5039 and MAE of 16.6923. To find a better model which cater the instability of the NR prices properly, a dynamic machine learning technique, Time Delay Neural Network (TDNN) was employed. The architecture of the identified TDNN model with the hyper-parameter tunning consists of one hidden layer with sixteen neurons, and 1:16 time delays and exhibits lower errors: RMSE of 0.01347 and MAE of 0.0074. It can be concluded that TDNN perform better than the ARIMA model in forecasting NR prices Sri Lanka.","PeriodicalId":308901,"journal":{"name":"2022 6th SLAAI International Conference on Artificial Intelligence (SLAAI-ICAI)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130960865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research study, Received Signal Strength Indicators (RSSI) and ML-based solutions are proposed for indoor localization. Although the RSSI-based position techniques are much more interested in position estimation, as it does not require any additional hardware, the precision remains a significant issue because of the considerable fading effects, multipath propagation, and different parameters in the indoor environments. This research study examines ML-based Indoor Positioning Systems (IPS) using different signal filtering techniques. In this work, RSSI signals are filtered separately using three filters, Moving Average, Gaussian and Median, and the impact on position estimation is observed. To examine each filter’s performance, the error is compared in terms of statistical figures of RMSE (Root Mean Squared Error) and R2 (Coefficient of Determination). Most widely used Random Forest Regression (RFR) and Extra Tree Regressor (ETR) have been used as the Supervised ML techniques, and results are compared. According to the experimental results, the above filters can reduce the position estimation error to a maximum of 12 cm, which is negligible in many IPS applications with the ETR ML technique.","PeriodicalId":308901,"journal":{"name":"2022 6th SLAAI International Conference on Artificial Intelligence (SLAAI-ICAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116876236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
