The difficulties with the k-nearest neighbor algorithm is option c. none of the above.

<h3>What problems does the K-nearest Neighbor algorithm have?</h3>

An unlabelled point is given a label based on its proximity to all other nearby labelled points. This is how it works. Its main drawbacks are that picking the "right" value of K is challenging and that it is highly computationally inefficient.

Hence, The supervised machine learning technique known as the k-nearest neighbors (KNN) can be used to tackle classification and regression issues. It is simple to use and comprehend, but it has the important problem of becoming noticeably slower as the amount of data in use increases.

A ___ is a node (or a device) that connects two different networks together and allows them to communicate.
stellarik [79]

Answer:

The answer is Hub

Explanation:

A hub, also called a network hub, is a common connection point for devices in a network. Hubs are devices commonly used to connect segments of a LAN. The hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

  • Your computer is running more slowly than usual
  • Your computer crashes frequently
  • Your computer has pop-up ads or other unwanted behavior
  • Your default homepage or search engine has changed without your permission
  • You see new icons or programs on your desktop that you didn't install

• What advantage does a circuit-switched network have over a packet-switched network? What advantages does TDM have over FDM in
lions [1.4K]

Answer:

Advantages of both circuit switched networks and TDM are given below:

Explanation:

Advantages of circuit switched network over packet switched network:

  • Circuit switched network has the advantage of being physically connected and having a dedicated channel for communication between the sender and the receiver which also makes it more reliable. Packet switched networks do not have a dedicated channel hence, they are not that reliable.
  • Circuit switched networks are used for voice calls because there is no timing jitter or delay in these types of networks while packet switched networks do not offer this advantage.

Advantages of TDM over FDM in a circuit switched network:

  • TDM is time division multiplexing i.e. multiple information is sent in different time intervals but on the same frequency. While FDM sends information using different frequencies. So, the advantage of using TDM is that the information will be sent from the sender to the receiver using only a single frequency.
  • Using TDM, bandwidth is saved because it only sends information on a single frequency unlike FDM.
  • In TDM, there is low chance of interference between signals since they are sent in different time intervals from the sender to the receiver. While FDM has a higher chance of interference.

Write a filter that reads in a sequence of integers and prints the integers, removing repeated values that appear consecutively.
lara31 [8.8K]

Answer:

Following is the code for filter:

public class filter

{ public static void main(String[] args)

{ int x = StdIn.readInt();

System.out.print(" " + x + " ");

while(!StdIn.isEmpty())

{ int y = StdIn.readInt();

    if(y != x)

          System.out.print(" " + y + " ");

    x = y;

    }

    }

    }

Explanation:

  • A public class filter is used.
  • The main function will accept a single argument as string[], it is also known as java command line argument.
  • Now the Stdln.readInt is used to read the integers in the sequence and store it in integer x.
  • The value stored in variable x will be printed using System.out.print
  • Now unless the Stdln.readInt gets an empty value, check each value of sequence and store in variable y.
  • If y is not equal to previous value x, print it and shift the value of y into x.
  • Repeat the loop again.

i hope it will help you!
