Traffic congestion caused by greater competition for limited parking spaces in the world's major cities is a growing problem. To overcome this challenge, a study has been carried out to use a smart parking application that utilises machine learning algorithms to help predict future car parking occupancy rates at Port Macquarie campus of Charles Sturt University (CSU), Australia. Parking data was collected over a five-week period and the WEKA Machine learning Workbench was used to identify high-performing algorithms for predicting future parking occupancy rates. In the initial phase, some well known algorithms were used to investigate occupancy rates. In the next phase of the study, student class timetable data was used to enhance prediction accuracy and investigate parking occupancy trends. While most algorithms proved to be accurate in stable conditions, the KStar algorithm appeared to produce better results during highly variable conditions.

Recognizing named entities in Adverse Drug Reactions narratives is a crucial step towards extracting valuable patient information from unstructured text and transforming the information into an easily processable structured format. this motivates using advanced data analytics to support data-driven pharmacovigilance. Yet existing biomedical named entity recognition (NER) tools are limited in their ability to identify certain entity types from these domain-specific narratives, resulting in poor accuracy. To address this shortcoming, we propose our novel methodology called Tiered Ensemble learning System with Diversity (TELS-D), an ensemble approach that integrates a rich variety of named entity recognizers to procure the final result. there are two specific challenges faced by biomedical NER: the classes are imbalanced and the lack of a single best performing method. the first challenge is addressed through a balanced, under-sampled bagging strategy that depends on the imbalance level to overcome this highly skewed data problem. To address the second challenge, we design an ensemble of heterogeneous entity recognizers that leverages a novel ensemble combiner. Our experimental results demonstrate that for biomedical text datasets: (i) a balanced learning environment combined with an ensemble of heterogeneous classifiers consistently improves the performance over individual base learners and (ii) stacking-based ensemble combiner methods outperform simple majority voting based solutions by 0.3 in F1-score.

Analog circuits play important roles in modern electronic systems. Incipient fault diagnosis of analog circuits is a recognized challenging research direction due to the difficulty of fault feature extraction and identification. this paper proposes an early fault diagnosis algorithm for analog circuits based on multilayer extreme learning machine (ML-ELM).Its basic idea comes from the Auto-encoder(AE) and the Extreme learning Machine (ELM). the proposed method which combines the characteristics of both, so it has the ability of feature extraction and fast training speed. In this method, the time domain sampling signal of the circuit can be directly used as the fault sample, and the unsupervised feature extraction is carried out layer by layer through the deep network, the diagnosis results are obtained after the supervised classification by the traditional ELM algorithm. the whole process does not rely on multi-step iterative and reverses fine-tuning. the experimental results of the Sallen-Key band-pass filter circuit and Leapfrog low-pass filter circuit show that the method has not only high diagnosis accuracy, but also fast diagnosis speed. Because this method gets rid of the tedious manual feature extraction and complex signal processing, it improves the training efficiency and makes the method more universal.

Nowadays application scopes of deep learning research in the machine learning subfield have been gradually expanded, mainly in the field of computer vision and natural language processing. However, in the latter NLP field, there is very little semantic excavation research on agricultural literature data. this paper bases on the attempting to combine relevant paradigms of semantic mining techniques and characteristics of agricultural digest data, for the service of providing new methods and technologies of information acquisition and analysis in the agricultural information domain. data cleaning methods and data mining experiment are mainly based on deep learning algorithms, which are Seq2Seq and attention mechanism. Finally, through qualitative evaluation and quantitative evaluation of the experimental results, which based on the ROUGE evaluation index system, the experiment shows that the semantic mining model has reached the optimal level of model evaluation in the certain range.

Diabetes is one of the worlds major health problems according to the World Health Organization. Recent surveys indicate that there is an increase in the number of diabetic patients resulting in an increase in serious complications such as heart attacks and deaths. Early diagnosis of diabetes, particularly of type 2 diabetes, is critical since it is vital for patients to get insulin treatments. However, diagnoses could be difficult especially in areas with few medical doctors. It is, therefore, a need for practical methods for the public for early detection and prevention with minimal intervention from medical professionals. A promising method for automated diagnosis is the use of artificial intelligence and in particular artificial neural networks. this paper presents an application of Multi-Layer Feed Forward Neural Networks (MLFNN) in diagnosing diabetes on publicly available Pima Indian Diabetes (PID) data set. A series of experiments are conducted on this data set with variation in learning algorithms, activation units, techniques to handle missing data and their impact on diagnosis accuracy is discussed. Finally, the results are compared with other states of art methods reported in the literature review. the achieved accuracy is 82.5% best of all related studies.
