حسنًا، لقد اقتربنا من النهاية نوعًا ما هنا.
All right so we kind of zoomed ahead to the end there.
إذن لنأخذ خطوة إلى الخلف ونراجع ما قمت به للتو ولكن ببطء أكبر.
So let's take a step back and walk through what I just did but much more slowly.
سترون جميع الخطوات التي قمت بها عندما قمت
You're going to see all the steps that I went through when I
بكتابة تعليمة Python البرمجية التي وضعت حد القرار.
wrote the Python code that just made that decision boundary.
وبنهاية مقطع الفيديو التالي أو مقطعي الفيديو التاليين،
And by the end of the next video or
ستكون لديكم القدرة على كتابة هذه التعليمة البرمجية بأنفسكم.
two, you will be able to write this code yourself.
والمكان الذي سنبدأ منه هو [LAUGH]‏ Google كعادتنا.
So the place that we start [LAUGH] as always maybe is Google.
وتوجد هناك مكتبة Python التي سأستخدمها كثيرًا في هذا الدرس،
So there's a Python library that I'm going to be using a lot in this lesson, and
وسوف نستخدم Google لمساعدتنا في الاستفادة من وثائق
we're going to be using Google to help us use the documentation of
هذه المكتبة لمعرفة كيفية استخدام بعض الدالات الموجودة بها.
that library to figure out how to use some of the functions that it has.
اسم هذه المكتبة هو scikit-learn، وعادةً يتم اختصاره إلى sk-learn.
The name of this library is scikit-learn, which is often abbreviated sk-learn.
إذن دعوني أعرفكم على هذا التقليد الآن.
So let me get you used to that convention now.
إذن سأقوم بالبحث عن sklearn
So I'm going to search google for sklearn and
واسم الخوارزمية التي استخدمتها للتو في google، وهي بالمصادفة مصنِّف بايز المبسط.
the name of the algorithm that I just used, which happens to be Naive Bayes.
وسوف نعود مجددًا إلى هذا الأمر ونتحدث عن وظيفة مصنِّف بايز المبسط بالضبط خلال وقت قصير.
We'll go back in a little bit and talk about what Naive Bayes does exactly.
ولكنني أريد أن أجعلكم تشغلون التعليمة البرمجية أولاً.
But first I want you to have you running the code.
إذن، ما سنبحث عنه هو مصنِّف بايز المبسط في sklearn.
So sklearn Naive Bayes.
لنرى ما الموجود.
See what's out there.
توجد هنا صفحة تتحدث عن مصنِّف بايز المبسط توفر
There's a page on Naive Bayes here that gives you
اشتقاقًا من صيغة مصنِّف بايز المبسط ومجموعة من حالات الاستخدام.
a derivation of the Naive Bayes formula and then a bunch of use cases,
ومن ضمن ذلك ما يسمى بمصنِّف بايز المبسط الغاوسي،
including something that says Gaussian Naive Bayes and, as it turns out,
وهذا هو ما سأستخدمه كما يتبين.
this is what I'm going to be using.
إذن لنعد إلى الصفحة السابقة لأني رأيت مصنِّف بايز المبسط الغاوسي كأحد
So let's head back because I saw Gaussian Naive Bayes as one of
النتائج الأخرى في Google.
the other results on Google.
وهذه هي. مصنِّف بايز المبسط الغاوسي،
That's this one. Gaussian Naive Bayes,
هذه هي الطريقة التي استخدمتها بالفعل لكتابة المصنِّف الذي رأيتموه للتو.
this is what the way that I actually wrote classifier that you just saw.
