Mllib is a machine learning library provided by spark. By calling the algorithm encapsulated by mllib, machine learning applications can be easily constructed. It provides a wealth of machine learning algorithms, such as classification, regression, clustering and recommendation algorithms. In addition, mllib standardizes the API for machine learning algorithms, making it easier to combine multiple […]

Click to watch the big guy share The success of deep learning is based on a large number of clean data and deep models, but the data and models are often not ideal in real scenes, for example, there are many label noises in the data, or considering the reasoning speed of the model, the […]

The notes are reproduced in GitHub project：https://github.com/NLP-LOVE/Introduction-NLP 10. Text clustering As the saying goes, birds of a feather flock together. When people get data, they need to sort out, archive similar data together, and automatically discover the similarity between a large number of samples. This task of archiving according to similarity is called clustering. 10.1 […]

Hello readers, in this article, we try to use sklearn library to compare the implementation and results of K-means clustering algorithm and principal component analysis (PCA) in image compression. The effect of the compressed image is evaluated by the reduction of occupancy and the difference from the original image. The purpose of image compression is […]
