Assume:
There are hundred students and each on
of them are working on a common
project.
Ideally, being consistent implies that a student works everyday on the project at-least once.
If we have data like this:
Student 1 work day 1(worked)
day 2(worked)
day 3(took a break)
etc
Now is there any algorithm that can be used to check and rank students based on consistency ?
EDIT:
This is not a homework problem. I am developing a plugin in java that rates group work according to consistency. So I was wondering if there was an algorithm that can accurately predict consistency. I was thinking about using standard deviation but if there is something more precise, it would help.
I believe the quantity you are looking for is called variance. This describes consistency, if you were to say, use the time each day that a student works.

Now. I build a formula for news to get list hot news.
have any factor as pageview, time,content.
what does a solution for this problem?
Thanks
You can try a machine learning approach for this problem.
Extract your features, and give each a numeric value (you can use
the Bag of Words model for content). Note that some feature selection algorithm might be needed.
Manually label large enough set of examples - and give each of them a score according to its importance.
Use linear regression and build a function that evaluates each article and gives it a score.
Now that you have your regression function, you can use it to give score to each article. Use it to achieve the raw score.
For post processing - combine this score with the time in a second function to get the article's final score. #MattBall's suggested link seems like reasonable approach.

I am planning to display an android calendar in my application. I want to select a date to use in my application. I need to know whether there is an algorithm for a calendar.
I must not use any open source application.
Generating an arbitrary Gregorian calendar pretty much amounts to determining the day of the week of the starting day and, for Februaries, determining whether the year is a leap year.
The best and most famous date algorithm is Conway's Doomsday Rule, http://en.wikipedia.org/wiki/Doomsday_rule

I have a big database of jobs, each job has numerical and non numerical attributes like(position,field,salary, needed experience...)
and applicants to jobs that determine some attributes like(age, expected salary...)
I want to create an application that do automatic matching between the jobs and the appropriate candidates*What is the best Algorithm to apply (data mining or artificial intelligence) to implement this app.*
thx for your replies
It seems that what you want is a recommendation algorithm, not matching algorithm.
There is not best recommendation algorithm which work for all cases. You should look into several algorihms and select which suits best for your situation. I recommend you to look at Apache Mahout which implements lots of such recommendation algorithms and is an open-source library.

I want to know if is there any specific algorithm that can be followed to understand the meaning of a word/sentence/paragraph. Basically, I want to write a program that will take text/paragraph as input and try to find out what its meaning is. And thereby highlight the emotions within the text.
Also, if there is an algorithm to understand things, can the same algorithm be applied to itself? It reduces the quest further to a point where we become interested in knowing meaning of meaning OR rather definition of definition.
You want Natural Language Processing and Semantic Technology. This is still a flourishing area in computer science. Look at things such as a Semantic Reasoner. You can start with Jena. There are also other things you can look at such as Academic Thesis papers.

I am starting a new project which have an interface like picasa 3. Please let me know what all documents i have to prepare in advance before starting the project. Right now i am only developer but in the future other developers may join.
Is there any third-party components which will help me simplify the task of theming and creating buttons?
Thanks in advance,
John
Indeed your question is actually 2 questions. For things to prepare when starting a development project:
schedule and cost estimation report (use a cost estimation software)
project design specification
project logical block diagram (can be UML or just Visio)
technological feasibility report
business presentation based on the above documents
depending on your venture model, you may be required to present your investors with further reports and presentations.
