some aspects certainly changed, Of course, this change is not necessarily caused by disease (often referred to as noise), but the occurrence and detection of anomalies is an important starting point for disease prediction. Similar scenarios can also be applied to credit fraud, cyber attacks, and so on.General outlier detection methods are based on statistical methods, based on the method of clustering, and some special methods to detect outliers, the

Outlier is one of the key points of model optimization, the previous knowledge of outliers only know that even outliers are far from the mean, but how far is far enough, in fact, different models have different considerations, based on the impact of the model is different, so can endure the outliers are different.1, the type of the exception valueFrom the two-dim

similar to the original data after filling, and the overall characteristics of the data are basically maintained during the filling process.Second, the abnormal valueOutliers are also very hated a kind of dirty data, outliers tend to pull up or pull down the overall situation of the data, in order to overcome the impact of outliers, we need to deal with outliers

The above enumerated user behavior is more general, the recommendation

different behavior, calculate the different user/item similarity. Like Dangdang or Amazon, "the person who bought the book also bought ...", "the person who viewed the book also viewed ..." They are weighted according to the extent to which the different behaviors reflect user preferences, resulting in a user's overall preference for items. In general, explicit user feedback is larger than implicit weights, but relatively sparse, after all, the n

Big Data Glossary The emergence of big data has brought about many new terms, but these terms are often hard to understand. Therefore, we use this article to provide a frequently-used big data glossary for your in-depth understanding. Some of the definitions refer to relevant blog articles. Of course, this glossary does not contain 100% of all terms. If you think there are any omissions, please let us know.
