What is the purpose of oversampling?

Oversampling is capable of improving resolution and signal-to-noise ratio, and can be helpful in avoiding aliasing and phase distortion by relaxing anti-aliasing filter performance requirements.

What is the science of polling?

Applications. Psephology is a division of political science that deals with the examination as well as the statistical analysis of elections and polls. People who practice psephology are called psephologists.

What does oversampling mean in statistics?

Both oversampling and undersampling involve introducing a bias to select more samples from one class than from another, to compensate for an imbalance that is either already present in the data, or likely to develop if a purely random sample were taken.

Does oversampling cause bias?

In the case of oversampling if you are doing it before splitting you would be adding bias to the accuracy because you will be comparing a data-point with it’s oversampled counterpart (which were generated artificially).

Which of the following are the disadvantages of oversampling?

Oversampling unnecessarily increases the ADC output data rate and creates setup and hold-time issues, increases power consumption, increases ADC cost and also FPGA cost, as it has to capture high speed data.
