The Dictionary class generally provides better performance compared to the Hashtable class. The Dictionary class is implemented as a generic collection and uses hashing and indexing techniques optimized for performance. It has better lookup and retrieval times, especially for large data sets. The Hasht...
Encryption is a reversible process. After encryption, you can decrypt the data to its original form, ensuring that authorized individuals can access and comprehend the information. This property distinguishes encryption from irreversible techniques like hashing, which convert data into a fixed-length stri...

1) I think this helped a lot. I was confused what the hashing trick was doing. I was thinking perhaps the value of a feature, say 5a9ed9b0, was REPLACED by an integer. So, I understand now that one-hot-encoding is still being used, it is just the indexing of the data which is...
Hashingis a technique of converting a large String to a small String that represents the same String. A shorter value helps in indexing and faster searches. HashSet also uses HashMap internally. It internally uses a link list to store key-value pairs already explained inHashSetin detail and ...
