In the proposed algorithm, the authors use two steps to maximise an ML metric to obtain first the frequency offset and then timing. A fast Fourier transform algorithm is used to estimate the frequency offset. Using these two estimates, the channel is identified. A simple iterative algorithm is...
The most essential factors connected with input data that are used to classify the data are known as features. Defining specific qualities of an item called features is critical in classification. For classification, features extracted from visual objects are employed [20]. ML is a branch of AI...
That’s why forecasting is commonly used in business and finance. Semi-Supervised ML Algorithms Supervised and unsupervised machine learning algorithms are very common for the majority of AI tasks today. Here’s a simple cheat sheet to facilitate your choice of a machine learning algorithm: How ...
Machine learning algorithms are widely used in ATS systems like Alguliyev, Aliguliyev, Isazade, Abdi, and Idris (2019), Shetty and Kallimani (2017), Yousefi-Azar and Hamey (2017). Machine learning algorithms are categorized as: supervised, unsupervised, or semi-supervised. Supervised Learning ...
This repository collects some codes that encapsulates commonly used algorithms in the field of machine learning. Most of them are based on Numpy, Pandas or Torch. You can deepen your understanding to related model and algorithm or revise it to get the cu
In supervised learning, each data point is labeled or associated with a category or value of interest. An example of a categorical label is assigning an image as either a ‘cat’ or a ‘dog’. An example of a value label is the sale price associated with a used car. The goal of supe...
In total, 1011 myopic children aged 6 to 18 years participated in this study. Cross-sectional datasets were used to optimize the ML algorithms. The input variables included age, sex, central corneal thickness (CCT), spherical equivalent refractive error (SER), mean K reading (K-mean), and...
Finally, it is showed that the extracted features can also be used in feature based probabilistic SLAM methods such as Kalman Filters, Information Filters, and Particle Filters after applying merging procedure. Since the plane segments are already registered, the data association problem can be ...

A large number of features can bog down some learning algorithms, making training time unfeasibly long.Support vector machinesare well suited to scenarios with a high number of features. For this reason, they have been used in many applications from information retrieval to text and image classifi...
