Decision Tree algorithm is one of the simplest yet most powerful Supervised Machine Learning algorithms. Decision Tree algorithm can be used to solve both regression and classification problems in Machine Learning. That is why it is also known as CART or Classification and Regression Trees. As the...
The following are the advantages of decision tree algorithm over other algorithms:It can be applied to both categorical & numerical data. Doesn't need much of Data Pre-processing. It can recover from outliers. Gives the privilege to add more parameters for better precision and accuracy. Can be...
Machine learning on trees has been mostly focused on trees as input. Much less research has investigated trees as output, which has many applications, such

This study thus establishes a comprehensive proof-of-concept that methodologies based on artificial intelligence can substantially accelerate tree-search algorithms without sacrificing accuracy. Results A machine-learning algorithm for accelerating the maximum-likelihood tree search...
Laser-scanned point clouds of forests make it possible to extract valuable information for forest management. To consider single trees, a forest point cloud needs to be segmented into individual tree point clouds. Existing segmentation methods are usually based on hand-crafted algorithms, such as ide...
In this chapter, we reviewed two classification techniques: KNN and SVM. The goal was to discover how these techniques work and ascertain the differences between them, by building and comparing models on a common dataset. KNN involved both unweighted and weighted nearest neighbor algorithms, and fo...
Finally, model was compared with standard machine learning (ML) algorithms and the proposed model outperformed all of them. The proposed model will aid in predicting novel and immunodominant TCEs of ZIKV. The predicted TCEs may have a high possibility of acting as prospective vaccine targets ...
