supervised learning : In short, given a certain training sample (it is important to note that the sample is both data and data corresponding to the results), using this sample training to get a model (can be said to be a function), and then use this model to map all the input to the corresponding output, The output is then simply judged so that the problem of classification (or regression) is achieved. Simply make a distinction, the classification is discrete data, regression is continuous data.

Earlier, we mentioned supervised learning, which corresponds to non-supervised learning in machine learning. The problem with unsupervised learning is that in untagged data, you try to find a hidden structure. Because the examples provided to learners arenot marked, so there is no error or reward signal to evaluate the potential solution. This differs from supervised learning and intensive learning unsupervised
The common methods of machine learning are mainly divided into supervised learning (supervised learning) and unsupervised learning (unsupervised learning).Supervised learning, which is often said to be classified , is trained to obtain an optimal model (a set of functions, the best of which is optimal under a certain evaluation criterion) through the training sample ( known data and its corresponding output

without concept marks (classifications) are studied to discover the structural knowledge in the training sample set. Here, all the tags (categories) are unknown. Therefore, the training sample is of high ambiguity.The common unsupervised learning algorithms are clustering.The above describes supervised learning. Recalling the data set at the time, the table shows that each piece of data in the data set has been labeled negative or positive, i.e. beni

I have read some papers at ordinary times, but I always feel that I will slowly forget it after reading it. I did not seem to have read it again one day. So I want to sum up some useful knowledge points in my thesis. On the one hand, my understanding will be deeper, and on the other hand, it will facilitate future surveys. You can al

Usage· This tool combines the functionality of the ISO Clustering tool with the maximum likelihood classification tool. Outputs a classified raster. As an option, it can also output feature files.· The feature file generated by this tool can be used as input to other classification tools, such as the
I. Main Ideas
When deep learning is applied to target detection, Data enhancement usually increases the training data volume without the additional tag cost. Data enhancement reduces overfitting and increases algorithm performance. This article mainly verifies whether data enhancement can be used as the main component of the unsupervised feature learning architecture. Implementation path: first, some image blocks are randomly collected as seed images,
Unsupervised learningUnlike supervised learning, data is not labeled (categorized) in unsupervised learning. Unsupervised learning requires algorithms to find the inherent laws of these data and classify them. (as in the data, and there is no label, it can be seen that the data set can be divided into three categories, it is an
Machine learning is divided into supervised machine learning, unsupervised machine learning, and semi-supervised machine learning. The criterion for dividing it is whether the training sample contains human-labeled results. (1) Supervised machine learning: a function is learned from a given set of training data, and when new data arrives, the result can be predicted based on this function. The training set requirements for supervised learning are both
machine learning is divided into two types: supervised learning and unsupervised learning . Next I'll give you a detailed introduction to the concepts and differences between the two methods. Supervised Learning (supervised learning): train through an existing training sample (known data and its corresponding output) to obtain an optimal model, and then use this model to map all new data samples to the corresponding output, The optimal model also has
The last three weeks of Andrew Ng's machine learning were recently followed by the linear regression (Linear Regression) and logistic regression (logistic Regression) models in machines learning. Make a note here.Also recommended a statistical study of the book, "Statistical Learning method" Hangyuan Li, Book short, only 200 pages, but the content is basically covered the theoretical basis of machine learning.Notes Machine learning : It is a subject of computer -based probabilistic statistical m

In the process of learning deep learning, the main reference is four documents: the University of Taiwan's machine learning skills open course; Andrew ng's deep learning tutorial; Li Feifei's CNN tutorial; Caffe's official website tutorial;
Comparing these data, there was a sudden confusion: the DA and Andrew Tutorials used a lot of space to introduce unsupervised self-coding neural networks, but they were hardly involved in the caffe of L

Deep networking has the following drawbacks: The deeper the network, the more training samples are needed. If the use of supervision will require a large number of samples, or small-scale samples can easily lead to overfitting. (Deep network means more features, machine learning faces multiple features: 1, multi-Sample 2, Rule 3, Feature selection) the optimi

1. Maximum likelihood and maximum probability
Because it is not a class background, when we first came into contact with the maximum likelihood, it was always strange why it was called the maximum likelihood instead of the maximum probability?
It was later known that the maximum likelihood was used to estimate unknown parameters. The maximum probability expression is more suitable for solving the variable with the maximum probability when known parameters are known. For example:
Max L (θ) = θ 1x
