KNN-WG Screenshot Version 1.0 License Commercial $34.95 Platform Windows Supported Languages English The K-nearest neighbors (K-NN) method is a valuable approach that originated as a non-parametric statistical pattern recognition procedure used to differentiate between diverse patterns based on a selection criterion. This technique provides researchers with the ability to generate future data. KNN operates by resampling the values from the observed record conditionally, based on the specified conditional relationship. This simplistic technique is considered the most promising non-parametric method for generating weather data.One of the most popular applications of K-NN is the generation of weather data. It is based on recognizing a similar pattern of target data within 641 Accesses AbstractPiezoelectricity or piezoelectric science remained an interesting phenomenon for some crystals since its discovery in 1880. The discovery of piezoelectric properties in polycrystalline ceramics around 1944 led to the establishment of an interesting connection between piezoelectricity and crystal symmetry analogous to the magnetic phenomenon. With the volatile nature of the widely used lead zirconate titanate (PZT) being an alarming toxic issue in the environment during processing and handling, identifying new lead-free substitutes with similar properties become an incentive for replacements of PZT ceramics. Of numerous piezoceramics, sodium–potassium niobates (KNN) have been established as promising polycrystalline candidates as potential replacements for PZTs. These materials can be processed easily using the simple double sintering conventional technique. Their properties are strongly dependent on various factors such as compositional formula, impurities/substituents, preparation method, sintering conditions like type, temperature and time, etc. The density, structural and microstructural properties that predominantly control the piezoelectric behavior are strongly dependent on the preparation process. The requirement to minimize the evaporation of constituent materials and simultaneously obtain high density, uniform microstructure, and desired crystal phase polycrystalline ceramics demands careful sintering. The chapter focuses on the sintering of certain KNN-based polycrystalline piezoceramics by different sintering techniques like conventional, microwave techniques and reports on the structural and electrical properties.

Image source: to Wikipedia Cardiovascular is the leading cause of death globally [1]. It is a combination of different heart and blood vessels such as heart diseases, heart attacks, stroke, heart failures, arrhythmia, heart valve problems, etc. High blood pressure, high cholesterol, diabetes, physical inactivity are some major causes for increasing the risk of getting this disease. By minimizing behavioral risk factors such as smoking, unhealthy diet, using alcohol, and physical inactivity this disease can be prevented.If people can be aware in advance about this disease before it turns into a more risk level, we can minimize the number of deaths and high-risk level patients at a considerable amount. With the aid of development in Machine Learning and high computational power have driven exponential advancement in Artificial intelligence in the field of medicine, where people can use these technologies and come up with a model and do the predictions to identify the likelihood of people getting this disease in earliest stages.In this article, a machine learning model has proposed and implemented to identify the likelihood of a person is having this disease or not by concentrating on factors like factual information, results of medical examinations, and patient information gathered from an online dataset [2]. K Nearest Neighbors algorithm which is a well-known and well-performing classification algorithm was used to implement this model.Algorithm SelectionK Nearest Neighbors is a simple algorithm but works incredibly in practice that stores all the available cases and classifies the new data or case based on a similarity measure. It suggests that if the new point added to the sample is similar to the neighbor points, that point will belong to the particular class of the neighbor points. In general, KNN algorithm uses in search applications where people looking for similar items. K in the KNN algorithm denotes the number of nearest neighbors of the new point which needed to be predicted.KNN algorithm is also known as a lazy learner because there is less learning phase of the model due to it’s pretty fast learning ability. Instead, it memorizes the training dataset and all the work happens at the time the prediction is requested.How does the algorithm work?Figure 1: Simple explanation of the KNN algorithm. Image by Tharuka SewwandiWhen we add a new point to a dataset using the KNN algorithm we can predict which class the new point is belonging to. In order to start the.

Python Implementation of K-Nearest Neighbours (kNN) AlgorithmK-Nearest Neighbours is considered to be one of the most intuitive machine learning algorithms since it is simple to understand and explain. Additionally, it is quite convenient to demonstrate how everything goes visually. However, the kNN algorithm is still a common and very useful algorithm to use for a large variety of classification problems. If you are new to machine learning, make sure you test yourself on an understanding of both of this simple yet wonderful algorithm.Read more on Medium: is a Python implementation of the K-Nearest Neighbours algorithm.It is important to note that there is a large variety of options to choose as a metric; however, I want to use Euclidean Distance as an example. It is the most common metric used to calculate distances among vectors since it is straightforward and easy to explain.Let’s compare our implementation with the one provided by scikit learn. I am going to use a simple toy dataset that contains two predictors, which are age and salary. Thus, we want to predict if a customer is willing to purchase our product. Finally, I will define both models and fit our data. Please refer to the KNN implementation provided above. I am selecting 5 as our default k value. Note that for the latter model the default metric is minkowski, and with p=2 is equivalent to the standard Euclidean metric.ResultsThe accuracy turned out to be 0.93, which is a pretty good result. The figure attached below is a visualization of our test set results. I am providing a single figure since both models are identical. However, I personally suggest using implementations that are provided already since our implementation is simple and inefficient. Moreover, it is just more convenient not to keep writing the exact same code every time. 1  What is the basis of KNN method for implementation?

More 1  What is the basis of KNN method for implementation? To simulate weather variables for a new day (t+1), days with similar characteristics as those simulated for day t are selected from the historical record. One of these nearest neighbors is then selected according to a defined probability distribution or kernel and the observed values for the day subsequent to that nearest neighbor are adopted as the simulated values for day t+1 (Sharif et al., 2007). In this software following steps were followed (For further details, refer to Sharif and Burn, 2006): Step1: Compute regional means of the aim variables across the S stations for each day of the historical record. Step 2: According to Yates et al. (2003) we should use a temporal window of 14 days that the window are considered as potential candidates to the current feature vector. Step 3: Compute mean vector of the station for each day. Step 4: Compute the covariance matrix, Ct for the current day t using the data block of size L×p. S Less
