I released a new iPhone app 5 days ago. Already it has received high ratings, and many downloads, so I think it can be quite successful. (It's currently ranked in the top 10 paid music apps.) What do you think is the best release strategy: Release many micro-updates, often. (Just 1 or 2 new features per update, as they are completed.)...
I am looking for a fast and efficient way to calculate the frequency of list items in python: list = ['a','b','a','b', ......] I want a frequency counter which would give me an output like this: [ ('a', 10),('b', 8) ...] The items should be arranged in descending order of frequency as shown above. ...
I can't find any understandable information on this topic. On the dutch wikipedia, I found that you can apply a z-transform which produces a formula in this form: www.music.mcgill.ca/~gary/618/week1/img15.gif This FIR filter is used as an example: upload.wikimedia.org/math/b/9/e/b9e2ed5184f98621922f716e5216f33d.png With the z-transform...
I found the code below on stackoverflow and it works well in finding the most common words in a string. But can I exclude the counting on common words like "a, if, you, have, etc"? Or would I have to remove the elements after counting? How would I do this? Thanks in advance. <?php $text = "A very nice to tot to text. Something nice to ...
Hello, I need a way to get the inout from the microphone and determine the the average frequency. Is there a library or something to handle this? Thanks ...
Counting distinct values in excel - frequency function yes I have read http://stackoverflow.com/questions/1425289/counting-distinct-values-in-excel-frequency-function I am try to count a column with different numbers column contains (search) 1 3 7 9 5 1 3 9 4 result looking for; C1 C2 1 = 2 2 = 0 3 = 2 4 = 1 etc ...
Hi all! hmmm, i need to get how important is the word in entire document collection that is indexed in the lucene index. I need to extract some "representable words", lets say concepts that are common and can be representable to whole collection. Or collection "keywords". I did the fulltext indexing and the only field i am using are te...
I want to find the interface supplied by windows to change the CPU frequency and core voltage. Thanks! ...
The company I work for have millions of documents that are stored and shared on multiple network drives mapped to users' drives (e.g.] d:\ to \server1\, etc). What I'd like to implement is to crawl over network drives and let users find files fast using a full-text indexing. My current indexing strategy is Lucene.net But I am not su...
Hi Given the following list ['Jellicle', 'Cats', 'are', 'black', 'and', 'white,', 'Jellicle', 'Cats', 'are', 'rather', 'small;', 'Jellicle', 'Cats', 'are', 'merry', 'and', 'bright,', 'And', 'pleasant', 'to', 'hear', 'when', 'they', 'caterwaul.', 'Jellicle', 'Cats', 'have', 'cheerful', 'faces,', 'Jellicle', 'Cats', 'have', 'bright', 'bl...
i create a table for transaction table using mysql... i need to retrieve the frequent transaction data from that table... how find the frequent data from the table help me! ...
I have a hash in Ruby that is storing the word frequency of a string, with the word as the key and the frequency as the value. words = a_string.split(/ /) freqs = Hash.new(0) words.each { |word| freqs[word] += 1 } freqs = freqs.sort_by {|x,y| y } freqs.reverse! freqs.each do |word, freq| puts word+' '+freq.to_s end I've read that...
I've got a sample size of 180 data points. Its somewhat of a noisy sine wave. Trying to figure out the period / frequency of the data . Working in Xcode - read over the Accelerate framework but it seems very complex. Any suggestions on how to get the period / frequency of the data ? ...
I'm looking for a (preferably simple) way to find and order the most common bytes in a python stream element. e.g. >>> freq_bytes(b'hello world') b'lohe wrd' or even >>> freq_bytes(b'hello world') [108,111,104,101,32,119,114,100] I currently have a function that returns a list in the form list[97] == occurrences of "a". I need th...
Hi -- I'm writing a .Net class library that's to connect to a specific Wifi network whose name is known in advance, when the signal strength is above a certain threshold. It all works beautifully, EXCEPT that peformance is a bit spotty. I have a polling thread that repeatedly calls WlanGetAvailableNetworks(). This loop performs wel...
Hi, I try to change the frequency of a single soundfile. I managed to do that in android with the SoundPool thing. But the result sounds really bad. So I stepped about the Fourier Transformation - but I am not sure if this is what I am looking for. I want to load a single file and change the frequency of that file every time that file...
I have a defrecord called a bag. It behaves like a list of item to count. This is sometimes called a frequency or a census. I want to be able to do the following (def b (bag/create [:k 1 :k2 3]) (keys bag) => (:k :k1) I tried the following: (defrecord MapBag [state] ...
Hi, I've got a FFT magnitude spectrum and I want to create a filter from it that selectively passes periodic noise sources (e.g. sinewave spurs) and zero's out the frequency bins associated with the random background noise. I understand sharp transitions in the freq domain will create ringing artifacts once this filter is IFFT back to t...
Hi guys. I am working on an application which has a large array containing lines of numbers, transNum[20000][200]//this is the 2d array containing the numbers and always keep track of the line numbers I am using a nested loop to look for the most frequent items. which is for(int i=0/*,lineitems=0*/;i<lineCounter;i++) { for(in...
My aim is to have a set of frequencies like 2 frequencies that represent the bits (0 and 1). I want to send those frequencies to the audio out through sound card. At the other end I connect the cord to mike in of the sound card. I like to sense that signal (generated series of 2 fixed frequencies) from other computer and re-form the data...
