How to choose the most suitable machine learning algorithm for your regression problem

The performance of different machine learning algorithms depends on the size and structure of the data. Therefore, unless we use traditional trial and error experiments, we have no clear way to prove that a choice is right.

Machine Learning Algorithm Overview: Random Forest & Logistic Regression

In any machine learning model, there are two sources of error: bias and variance. To better illustrate these two concepts, assume that a machine learning model has been created and the actual output of the data is known, trained with different parts of the same data, and as a result the machine learning model produces different parts of the data.

Machine Learning Algorithm Summary: Artificial neural network, deep learning and other

Learning methods depending on the type of data, there are different ways to model a problem. In the field of machine learning or artificial intelligence, people first consider the way of learning algorithms. In the field of machine learning, there are several main ways of learning.   It is a good idea to classify the algorithm according to the learning style, so that people can choose the most suitable algorithm according to the input data to get the best results when modeling and algorithm selection. Supervised learning: Under supervised learning, input data is called "training data", each group training number ...

What is machine learning? Why is it so important?

Machine learning is a multi-disciplinary subject that has emerged in the past 20 years and involves many disciplines such as probability theory, statistics, approximation theory, convex analysis, and computational complexity theory.

Machine learning algorithm spicy, for small white I, the scissors are still messy, and I sort out some of the pictures that help me quickly understand. Machine Learning algorithm Subdivision-1. Many algorithms are a class of algorithms, and some algorithms are extended from other algorithms-2. From two aspects-2.1 learning methods supervised learning Common application scenarios such as classification problems and regression problems common algorithms include logistic regression (logistic regression) and reverse-transmission neural networks (back propagation neural netw ...

Machine learning = statistics on "new bottled old wine"

This paper raises objections to this view, thinking that machine learning ≠ data statistics, deep learning has made a significant contribution to our handling of complex unstructured data problems, and artificial intelligence should be appreciated.

How to choose the appropriate machine learning algorithm

Machine learning is a combination of art and science. No machine learning algorithm can solve all the problems. There are several factors that can influence your decision to choose a machine learning algorithm.

Logic regression of "machine learning"

"Machine learning" logic regression advantage: The calculation cost is not high, easy to understand and realize, disadvantages: easy to fit, classification accuracy may not be high. What we want is to receive all the input and then predict the category. Output 0 or 1 in the case of two classes. A function of this nature, perhaps the original you have contacted, is called the Heaviside step function, that is, the unit steps functions. But this momentary jump is actually difficult to deal with. So, here we take the sigmoid function. G (z) =11+e?z in order to achieve logist ...
