However, there are more points possible for tackling an algorithm listed in Part 2 or 3. No matter which problem you choose for writing an algorithm, remember to answer the 2 questions at the end of the assignment as well.
May 20, The ancient skill of creating and performing spoken rhyme is thriving today because of the inexorable rise in the popularity of rapping.
This art form is distinct from ordinary spoken poetry because it is performed to a beat, often with background music. And the performers have excelled. Adam Bradley, a professor of English at the University of Colorado has described it in glowing terms.
And that raises an interesting question: Today, we get an affirmative answer thanks to the work of Eric Malmi at the University of Aalto in Finland and few pals.
These guys have trained a machine-learning writing algorithms to recognize the salient features of a few lines of rap and then choose another line that rhymes in the same way on the same topic. The result is an algorithm that produces rap lyrics that rival human-generated ones for their complexity of rhyme.
Various forms of writing algorithms crop up in rap but the most common, and the one that helps distinguish it from other forms of poetry, is called assonance rhyme. But they also assume a highly structured form of verse consisting of 16 lines, each of which equals one musical bar and so must be made up of four beats.
The lines typically, but not necessarily, rhyme at the end. To train their machine learning algorithm, they begin with a database of over 10, songs from more than rap artists.
Spotting assonant rhymes is not hard. The words must first be converted into phonemes assuming a typical American-English pronunciation. Finding rhymes is then simply a question of scanning the phonemes looking for similar vowels sounds while ignoring consonant sounds and spaces.
That immediately suggests a way of ranking the complexity of lyrics.
Malmi and co look for sequences of matching vowel sounds in the previous two lines or so. This measure has allowed them to rank all the rap artists in their database according to their rhyming density. The three rappers who head the list are Inspectah Deck, Rakim, and Redrama.
Rakim, in particular, is known for his multisyllabic rhymes. Curiously, the rapper Eminem, who is also famous for his multisyllabic rhymes, comes surprisingly low on the list.
They next set their machine learning algorithm, called DeepBeat, a task. Having mined the database, its goal is to analyze a sequence of lines from a rap lyric and then choose the next line from a list that contains randomly chosen lines from other songs as well as the actual line.
This it can do surprisingly well. Malmi and co start with a line from one rap lyric and ask the computer to search through the database for another line on the same topic that best rhymes.
It then repeats this process for the next line and so on.Of course, an algorithm can only be expressed as an actual program if all the details have been filled in. So, where do algorithms come from? Usually, they have to be developed, often with a lot of thought and hard work.
Skill at algorithm development is something that comes with practice, but there are techniques and guidelines that can help. Algorithmic Mathematics a web-book by Leonard Soicher & Franco Vivaldi This is the textbook for the course MAS Algorithmic Mathematics. This material is Firstly, to introduce the basic algorithms for com-puting exactly with integers, polynomials and vector spaces.
In doing so, the student is. In the sequential search algorithm, the minimum amount of work is done if the value being searched for is the ___value in the list. First The number of comparisions done by the selection sort algorithm does not grow at the same rate as the problem size n, instead it grows at approximately the __ of the rate.
