WebMar 1, 2024 · Traditional data cleaning focuses on quality issues of a dataset in isolation of the application using the data—Cleaning Before ML—which can be inefficient and, counterintuitively, degrade... WebMar 2, 2024 · Data cleaning is a key step before any form of analysis can be made on it. Datasets in pipelines are often collected in small groups and merged before being fed into a model. Merging multiple datasets means that redundancies and duplicates are formed in the data, which then need to be removed. WebApr 20, 2024 · ML community has been focusing on understanding the impact of noises to ML models without actually doing data cleaning. On one hand, many ML algorithms are robust to noises — there has been research showing that the noise introduced during the training process, via e.g., asynchronous execution and lossy data compression and … red burning face symptoms
