In the last decade, extreme learning machine (ELM), which is a new learning algorithm for single-hidden layer feed forward networks (SLFNs), has gained much attention in the machine intelligence and pattern recognition communities with numerous successful real-world applications. The ELM structure ...
Details of linear regression can be referenced in books talking about machine learning. For simplicity I'm going to discuss the gradient descent algorithm with a pretty simple linear regression model: ^y=wx+by^=wx+b where xx is the vector of training set, ^yy^ is the predicted vector, ww...
Similar guarantees are provable when additional constraints, such as cardinality constraints, are imposed on the output, though often slight variations on the greedy algorithm are required.

In this study, we propose a logistic model-based active learning procedure for binary response data named GATE algorithm. In addition to the common subject selection feature in active learning procedures, our algorithm can also identify the proper classification model with the given data. We propose...
With the development of artificial intelligence, path planning of Autonomous Mobile Robot (AMR) has been a research hotspot in recent years. This paper proposes the improved A* algorithm combined with the greedy algorithm for a multi-objective path planning strategy. Firstly, the evaluation function...
Then, we introduce CB-Boost ’s pseudo-code in Algorithm 1. The empirical C-bound of a distribution Q={π1,…,πn} of n weights over H={h1,…,hn} a set of n voters, on a learning sample S of m examples, is as follows. CQS=1−1m(∑i=1myi∑s=1nπshs(xi))2∑...

Wang [25] improved the greedy algorithm and introduced a multi-level subspace scheme with successive approximation, in which the errors of boundary nodes in present interpolation are the object of next interpolation. The interpolation accuracy is improved step by step and the size of linear ...
