Machine Learning using Python: how do I use matplotlib to plot the SVM? -


i'm new machine learning (using python). referred few books, not able figure out how plot svm using matplotlib.

please me plot following:

from sklearn.svm import svc features_train=[[0,0],[1,1],[2,2]] label_train=[1,2,3] features_test=[[1,2],[2,1]] clf=svc() clf.fit(x,y) pred=clf.predict(features_test) print(pred)

try code below , read comments. tyro. more detail may catch link mlextend in getting better insight of svm having matplotlib under it's hood.

import numpy np import pandas pd # more detail catch link below sklearn import svm mlxtend.plotting import plot_decision_regions import matplotlib.pyplot plt   # create arbitrary dataset example df = pd.dataframe({'planned_end': np.random.uniform(low=-5, high=5, size=50),                'actual_end':  np.random.uniform(low=-1, high=1, size=50),                'late':        np.random.random_integers(low=0,  high=2, size=50)} )  # fit support vector machine classifier x = df[['planned_end', 'actual_end']] y = df['late']  clf = svm.svc(decision_function_shape='ovo') clf.fit(x.values, y.values)   # plot decision region using mlxtend's awesome plotting function plot_decision_regions(x=x.values,                    y=y.values,                   clf=clf,                    legend=2)  # update plot object x/y axis labels , figure title plt.xlabel(x.columns[0], size=14) plt.ylabel(x.columns[1], size=14) plt.title('svm decision region boundary', size=16)

however, if unaware of pandas follow link: http://pandas.pydata.org/ docs. hope works

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...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
