So, here is how this looks to a machine learning person.

.حسنًا، هذا هو ما يبدو للشخص الذي يقوم بالتعلم الآلي

We're going to produce what's called a scatter plot.

.سنقوم برسم ما يُسمى بالرسم المبعثر

And, for simplicity, I'll just use two features.

.وللتبسيط، لن أستخدم إلا هاتين الميزتين فقط

There's tempo and intensity.

.هناك الإيقاع والشدة

And, tempo might go from relaxed to fast, and intensity, for

،قد يتدرج الإيقاع من البطء إلى السرعة

the time being, will be light or soaring.

.والشدة ستكون خفيفة أو مرتفعة، في الوقت الحالي

So, the song, Let it Go is mid-range in tempo, but quite intense.

.إذن، أغنية Let it Go هي أغنية ذات إيقاع متوسط ولكن بشدة مرتفعة

So, it would be a data point right over here.

.لذلك، ستكون نقطة البيانات الخاصة بها هنا

In for those songs, you can extract those features.

.وبالنسبة لتلك الأغاني، يمكنكم استخراج تلك الميزات

And, each song becomes a dot in this two

وكل أغنية تصبح نقطة في

dimensional diagram of tempo and intensity.

.هذا الرسم ثنائي الأبعاد الذي يضم الإيقاع والشدة

This is slow song, it's very intense.

.هذه أغنية بطيئة ولكن شدتها مرتفعة

And, this is a slow song that's just very light.

.وهذه أغنية بطيئة للغاية ذات شدة خفيفة

So, I'm adding here data points for many songs.

.لذلك، أضيف هنا نقاط البيانات للعديد من الأغاني

And, suppose, the green ones are the ones that Katie likes.

.ولنفترض أن تلك النقاط الخضراء هي النقاط التي تحبها Katie

Where as the red ones over here, are the ones that she doesn't like.

.بينما النقاط الحمراء هنا، هي التي لا تحبها

Suppose we encounter a new song with features for

لنفترض أننا نواجه أغنية جديدة تقع ميزاتها

right over here, in the spectrum.

.هنا مباشرة، في النطاق

Just looking at the data itself, that Katie would like this song, or

وبمجرد النظر إلى البيانات نفسها، نرى أن Katie قد تحب هذه الأغنية أو

doesn't like this song.

.لا تحب هذه الأغنية

So, just check the box on the right for like, or don't like.

."لذلك، ما عليكم سوى تحديد المربع على اليمين للاختيار "تحب" أو "لا تحب
