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
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
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 show
Objective Machine learning is divided into: supervised learning, unsupervised learning, semi-supervised learning (can also be used Hinton said reinforcement learning) and so on. Here, the main understanding of supervision and
The common methods of machine learning are mainly divided into supervised learning (supervised learning) and unsupervised learning (unsupervised learning).Supervised
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 co
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
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). Using this model to map all the input to the corresponding output, the output is simply judged to achieve the purpose of classification, it also has the ability to classify the unknown data. In peop
Deep Learning (3) Analysis of a single-layer unsupervised learning network Zouxy09@qq.com Http://blog.csdn.net/zouxy09 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 understa
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

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 architec
