What is the Min Sketch algorithm and how does it efficiently estimate the frequency of elements in a data stream?
The Min Sketch algorithm is a probabilistic data structure used to estimate the frequency of elements in a data stream. It works by maintaining a set of hash functions and a small array of counters. When an element is encountered in the stream, it is hashed using the hash functions, and the corresponding counters are updated. By keeping track of the minimum counter value for each element, the algorithm can provide an efficient estimation of the frequency of elements in the data stream with a small amount of memory usage.

How can one determine the running time of an algorithm?
The running time of an algorithm can be determined by analyzing its efficiency in terms of the number of operations it performs as the input size increases. This is often done using Big O notation, which describes the worst-case scenario for the algorithm's time complexity. By evaluating the algorithm's steps and how they scale with input size, one can estimate its running time.
How to find the running time of an algorithm?
To find the running time of an algorithm, you can analyze its efficiency by considering the number of operations it performs in relation to the input size. This is often done using Big O notation, which describes the worst-case scenario for how the algorithm's performance scales with input size. By analyzing the algorithm's complexity, you can estimate its running time and compare it to other algorithms to determine efficiency.
How can the RANSAC algorithm be utilized to estimate a homography matrix for robustly matching corresponding points in two images?
The RANSAC algorithm can be used to estimate a homography matrix by iteratively selecting random sets of corresponding points in two images and calculating the homography matrix for each set. The set with the most inliers (points that fit well with the estimated homography) is then chosen as the best estimate. This helps in robustly matching corresponding points between the two images.
What criteria determine the admissibility of a heuristic in problem-solving algorithms?
The admissibility of a heuristic in problem-solving algorithms is determined by its ability to provide a lower bound estimate of the cost to reach the goal state without overestimating. A heuristic is considered admissible if it never overestimates the cost to reach the goal, ensuring that the algorithm will find the optimal solution.
If the tcp round trip time rtt is currently 30 msec and the following acknowledgements come in after 26 32 and 24 msec respectively what is the new rtt estimate using the jacobson algorithm use a0.9?
RTT = alpha * RTT + (1-alpha)*M RTT = 30 RTT = 0.9 * 30 + 0.1 * 26 = 29.6 RTT = 0.9 * 29.6 + 0.1 * 32 = 29.84 RTT = 0.9 * 29.84 + 0.1 * 24 = 29.256 hope it's right

Why do the star appear close yet they are far away?
Because your eyes and brain are designed to most efficiently estimate the distance of things that can hurt you, things you can eat, and things with which you can procreate the species, not to efficiently estimate the distance of things that may look pretty and impressive but don't have much practical importance in your daily life.

What is the method used to calculate the recombination frequency between the linked genes based on the data provided?
The method used to calculate the recombination frequency between linked genes is called the mapping function, which uses the observed frequency of recombinant offspring to estimate the distance between the genes on a chromosome.
Why do you use envelope detection in an M-ary Frequency Shift Keying noncoherent Modulator?
Envelope detection is used in an M-ary Frequency Shift Keying noncoherent modular because LOs are not required. Moreover, an estimate of 1dB of more power compared to the Frequency Shift Keying coherent demodulation.
