Quick Answer: What Do You Mean By Noisy Data?

What is noisy data and how do you handle it?

The simplest way to handle noisy data is to collect more data.

The more data you collect, the better will you be able to identify the underlying phenomenon that is generating the data.

This will eventually help in reducing the effect of noise..

How can data mining remove noisy data?

Smoothing, which works to remove noise from the data. Techniques include binning, regression, and clustering. 2. Attribute construction (or feature construction), where new attributes are con- structed and added from the given set of attributes to help the mining process.

What do you mean noise?

Noise is unwanted sound considered unpleasant, loud or disruptive to hearing. From a physics standpoint, noise is indistinguishable from sound, as both are vibrations through a medium, such as air or water. The difference arises when the brain receives and perceives a sound.
