weka machine learning

The 1NN nearest neighbor algorithm for machine learning, called IB1 in Weka, is because instance base 1, which is a lazy learning algorithm based only on an instance of the nearest neighbor.The following summarizes, Weka in the IB1 source of

Conditions such as the following descriptive narrations:① If a constrained inequality GI is a convex (convex) function (a linear function belongs to a convex function)② constrained equation hi are affine (affine) functions (Shaped like H (w) =wtx+b)③ and exists W makes for all I,gi (W) In these if, there must be ω?,α?,β, so that Omega is the solution of

The previous article introduced the ARFF format, which is a proprietary WEKA format. Generally, We need to extract or obtain data from other data sources. WEKA supports conversion from CVS or from databases. The interface is shown in figure The WEKA installation directory contains a data directory containing some test data for testing and

1. write a new learning scheme. If you need to implement a learning algorithm that does not have a special purpose for WEKA, or if you want to experiment with machine learning, or you just want to learn more about the internal operation of an induction algorithm through hand

I personally think we can directly discuss data mining.AlgorithmAnd WEKA are too impatient to use. I learned data mining methods directly from the beginning. Some methods are difficult and boring. What I often think about is not the method itself, but "What is this ?". After WEKA is used, some things gradually become clearer, because the input and output give people a very intuitive feeling, and the

Clustering Algorithms are called unsupervised learning in data mining, which is opposite to supervised learning. Semi-Supervised Learning) The general process of clustering algorithms is divided: 1. Read the sample to be predicted 2. initialize the clustering algorithm (and set parameters) 3. Cluster samples using Clustering Algorithms 4. Print the clusterin

What is machine learning?"Machine learning" is one of the core research fields of artificial intelligence, its initial research motive is to let the computer system have human learning ability to realize artificial intelligence.In fact, since "experience" is mainly in the fo
