What is the primary trade-off between lossy and lossless data compression methods?
Lossy compression reduces file size by discarding some information, while lossless compression preserves all data but achieves less reduction.
Lossless compression always achieves smaller file sizes than lossy compression by removing all redundant data.
Lossy compression preserves all original data but compresses it more efficiently than lossless compression.

The choice between perfect fidelity and efficiency reshaped digital communication forever

What is the primary trade-off between lossy and lossless data compression methods?
Lossless compression removes unnecessary data to reduce file size more than lossy compression.
Lossy compression sacrifices some data accuracy for smaller file size, while lossless compression preserves all data but achieves less reduction.
Lossy compression always preserves all original data but compresses it more efficiently than lossless.

Information Gain
Information gain measures how much a feature reduces uncertainty in decision trees
4 Feb 2026
0
How does information gain help in constructing decision trees for classification?
By choosing the feature with the highest number of unique values regardless of class distribution.
By selecting the feature that maximizes the reduction in entropy, thus best separating the classes at each node.
By minimizing the total number of features used in the tree without considering class separation.
