python - Document plotting using Pyplot and sklearn -


i looking gain insight layout of document set. casting them numbers array using following approach sklearn. 

  pipeline = pipeline([("vect", countvectorizer()),                        ("tfidf", tfidftransformer()),])    matrix = pipeline.fit_transform(docs).todense()

if cluster them use

    kmeans = kmeans(n_clusters=2).fit(matrix)     data2d = kmeans.transform(matrix)

then plot them using pyplot

    plt.scatter(data2d[:,0], data2d[:,1], c = categories)

however, generates kmeans representation of dataset. there anyway of summing values in matrix , plotting them can see how relative each other, without using kmeans. representation consistent eveytime.

for coming after me. principle in question known multidimensional scaling. here useful blog explains principles behind it. https://de.dariah.eu/tatom/working_with_text.html

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
