In this issue, the editor will bring you the classic algorithms and applications of how to start Python3 machine learning. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Using the new version of python3 language and the popular scikit-learn framework, algorithms and programming fly together, from shallow to deep, step by step into the world of machine learning. What I have learned is not only a course, but also the ability to keep thinking.

Basic syntax of Python3

Basic knowledge of advanced mathematics, linear algebra and probability theory

The basic knowledge of machine learning is required to be zero in the course.

Import android.content.Context

Import android.net.ConnectivityManager

Import android.net.NetworkInfo

Public class NetworkUtils {

Public static boolean isNetworkAvailable (Context c) {

Context context = c.getApplicationContext ()

/ / obtain all connection management objects for mobile phones (including the management of wi-fi,net, etc.)

ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService (Context.CONNECTIVITY_SERVICE)

If (connectivityManager = = null) {

Return false

} else {

/ / get the NetworkInfo object

NetworkInfo [] networkInfo = connectivityManager.getAllNetworkInfo ()

If (networkInfo! = null & & networkInfo.length > 0) {

For (NetworkInfo aNetworkInfo: networkInfo) {

/ / System.out.println (I + "= status = =" + networkInfo [I] .getState ())

/ / System.out.println (I + "= type = =" + networkInfo [I] .getTypeName ())

/ / judge whether the current network state is connected or not

If (aNetworkInfo.getState ()) = = NetworkInfo.State.CONNECTED) {

Return true

}

}

}

}

Return false

}

To determine whether the WIFI can be opened.

@ param context

@ return

, /

Public static boolean isWifiEnabled (Context context) {

ConnectivityManager mgrConn = (ConnectivityManager) context

.getSystemService (Context.CONNECTIVITY_SERVICE)

TelephonyManager mgrTel = (TelephonyManager) context

.getSystemService (Context.TELEPHONY_SERVICE)

Return ((mgrConn.getActiveNetworkInfo ()! = null & & mgrConn

.getActiveNetworkInfo () .getState () = = NetworkInfo.State.CONNECTED) | | mgrTel

.getNetworkType () = = TelephonyManager.NETWORK_TYPE_UMTS)

}

/ * *

Judge whether it is a 3G network.

@ param context

@ return

, /

Public static boolean is3rd (Context context) {

ConnectivityManager cm = (ConnectivityManager) context

.getSystemService (Context.CONNECTIVITY_SERVICE)

NetworkInfo networkINfo = cm.getActiveNetworkInfo ()

If (networkINfo! = null

& & networkINfo.getType () = = ConnectivityManager.TYPE_MOBILE) {

Return true

}

Return false

}

/ * *

Judge whether it is wifi or 3G network

@ param context

@ return

, /

Public static boolean isWifi (Context context) {

ConnectivityManager cm = (ConnectivityManager) context

.getSystemService (Context.CONNECTIVITY_SERVICE)

NetworkInfo networkINfo = cm.getActiveNetworkInfo ()

If (networkINfo! = null http://www.smxfk.com/)

& & networkINfo.getType () = = ConnectivityManager.TYPE_WIFI) {

Return true

}

Return false

}

}
