WebProblem: different data sources (e.g. sales department, customer billing department, …) Differences: styles of record k eeping, conventions, time periods, primary keys, errors External data may be required (“overlay data”) Transformation: reformat for specific data mining algorithms (we’ll come back to this) WebSep 12, 2024 · This has a smoothing effect on the input data and can also reduce the chances of overfitting in the case of small data sets. Equal Frequency Binning: bins have an equal frequency. Equal Width Binnin g : bins have equal width with a range of each bin are defined as [min + w], [min + 2w] ‚Ķ. [min + nw] where w = (max ‚Äì min) / (no of bins). WebApr 25, 2024 · In your example data looks like this [0,4,12,16,16, 18, 24, 26, 28]. So if you choose frequency = 3 you end up with 3 bins: [0,4,12] [16,16, 18] [24, 26, 28] last element of bin 1 =12 first element bin 2 = 16 - bin boundary = (12+16)/2 = 14 - same logic also works for the second case. – El Burro Apr 25, 2024 at 13:11 onyx theatre nevada city
