How can these anomalies be spotted? 2.6MB And, for many, this is the first and major disadvantage. In computer science, in the context of data storage, serialization is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer, or transmitted across a network connection link) and reconstructed later in the same or another computer environment. The logistic regression model is often used over linear regression, particularly when it comes to modeling probabilities of outcomes. This makes unsupervised learning a less complex model compared to supervised learning techniques. After this we train our very own machine learning model without writing a single line of code! . In machine learning, while working with scikit learn library, we need to save the trained models in a file and restore them in order to reuse it to compare the model with other models, to test the model on a new data. Random forest algorithm can use both for classification and the regression kind of problems. Making a classifier. 39 Views.
