Expert Solution & Answer
Chapter 8, Problem 13E
Explanation of Solution
Concept of frequency
- Frequency is the logarithm of number of occurrences of the term that is divided by the number of terms in the document.
- The concept of term frequency does not make sense when it comes to small
databases with few attributes with each containing only a few words. - The relevance of any term does not depend on the number of occurrences of the term.
- The logarithmic increase in the term frequency is not a good indicator when the domain is very small...
Explanation of Solution
Similarity of two tuples
- The similarity of two tuples can be measured by cosine similarity metric.
- The only difference is that the values that...

1. Smart Home Automation:o Connect a temperature sensor and a fan to a home gateway.o Configure the home gateway so that the fan is activated when the temperature exceedsa set threshold (e.g., 30°C).2. WiFi Network Configuration:o Set up a wireless LAN with a unique SSID.o Enable WPA2 encryption to secure the WiFi network.o Implement MAC address filtering to allow only specific clients to connect.3. WLC Configuration:o Deploy at least two wireless access points connected to a Wireless LAN Controller(WLC).o Configure the WLC to manage the APs, broadcast the configured SSID, and applyconsistent security settings across all APs.
