So, here's what I would say.

فيما يلي ما أود قوله؛

I would say that the first example of recognizing someone's picture from

وهو يتعلق بأن المثال الأول الخاص بتمييز صورة شخص ما من بين

a bunch of tagged photographs is definitely a supervised classification example.

.مجموعة من الصور الفوتوغرافية الموسومة بعلامة هو بالتأكيد مثال على تصنيف خاضع للإشراف

This is something that Facebook does all the time when it does

ويشبه هذا الأمر ما يفعله Facebook طوال الوقت عندما يتعرف على

recognition on the photos that you upload there.

.الصور التي يتم تحميلها

Another popular one is recommender systems like Netflix and Pandora.

.تتمثل الطريقة الشهيرة الأخرى في أنظمة التوصية مثل Netflix وPandora

They look at the stuff that they know that you like already, and they try to

تطلع الأنظمة على المواد التي يعرفون أنها تعجبك بالفعل، ويعمدون نحو

figure out what the features of, of those things are, those movies or those

تحديد ميزات هذه الأشياء أو الأفلام أو

songs, and it recommends more movies or songs that have similar features to you.

.الأغاني، كما يوصون بالمزيد من الأفلام أو الأغاني التي تتضمن ميزات مشابهة لك

Fraud is probably not an example of supervised classification and

وفي الغالب لا يعد الاحتيال مثالاً على التصنيف الخاضع للإشراف

that's because we haven't really defined what a weird-looking transaction is.

.وهذا بسبب أننا لم نحدد بعد ماهية المعاملات الغريبة

We don't have an example of what that might mean.

.وليس لدينا مثال عما قد يعنيه الاحتيال

So there's ways that you could still do this, but

إذن، ثمة طرق لا يزال بإمكانكم اتباعها للقيام بذلك، ولكن

this would be an example of unsupervised learning and

يمكن أن يكون ذلك مثالاً على التعلم غير الخاضع للإشراف

we'll talk about that a little bit more later in the class.

.وسنتحدث بشأن ذلك بعد قليل في الفصل الدراسي

Another thing that's usually unsupervised learning is clustering, so

،والشيء الآخر الذي لا يُعد في الغالب تعلمًا غير خاضع للإشراف هو نظام المجموعات

in this example, we don't know what the types of students are.

.فنحن لا نعرف أنواع الطلبة كما في المثال

We might not even know how many different types we're looking for.

.نحن أيضًا قد لا نعرف كم عدد الأنواع المختلفة التي نبحث عنها

There's still ways that we can approach this problem, but

ولا تزال هناك أساليب يمكننا اتباعها للوصول إلى حل لهذه المشكلة، ولكن

this isn't an example where you have a big bank of training data where you

هذا ليس مثالاً تتوفر لكم فيه الكثير من بيانات التدريب حيث تعرفون

already know the correct answer.

.بالفعل الإجابة الصحيحة
