1
Welcome to machine learning.
2
What is machine learning?
3
You probably use it many times a day without even knowing it.
4
Anytime you want to find out something like, how do I make a sushi roll?
5
You can do a web search on Google, Bing, or Baidu to find out.
6
And that works so well because their machine learning software has figured out how to rank web pages.
7
Or when you upload pictures to instagram or snapchat
8
and think to yourself i want to tag my friends so they can see their pictures
9
well these apps can recognize your friends in your pictures
10
and label them as well that's also machine learning or
11
if you've just finished watching a star wars movie on a video streaming service
12
and you think what other similar movies could i watch well
13
the streaming service will likely use machine learning to recommend something
14
that you might like each time you use voice to text
15
on your phone to write a text message hey Andrew how's it going
16
or tell your phone hey Siri play a song by Rihanna
17
or ask your other phone okay Google show me Indian restaurants
18
near me that's also machine learning each time you receive an
19
email titled congratulations you've won a million dollars well maybe you're rich congratulations
20
or more likely your email service will probably flag it as spam.
21
That too is an application of machine learning.
22
Beyond consumer applications that you might use, AI is also rapidly making its way into big companies and into industrial applications. For example,
23
I'm deeply concerned about climate change and I'm glad to see
24
that machine learning is already hoping to optimize wind turbine power a generation.
25
Or in healthcare, it's starting to make its way into hospitals to help doctors make accurate diagnoses.
26
For recently, at Learning AI, I've been doing a lot of work putting computer vision into factories to help inspect
27
if something coming off the assembly line has any defects.
28
That's machine learning.
29
It's a science of getting computers to learn without being explicitly programmed.
30
In this class, you learn about machine learning and get to implement machine learning in code yourself.
31
Millions of others have taken the earlier version of this course, which is a course that led to the founding of Coursera,
32
and many learners ended up building exciting machine learning systems or even pursuing very successful careers in AI.
33
I'm excited that you're on this journey with me.
34
Welcome, and let's get started.

defect اسم/ˈdiːfɛkt/خَلَل, عَيْب
sushi اسم/ˈsuːʃi/سُوشِي
turbine اسم/ˈtɜː.baɪn/عَنَفَة, تُرْبِين

نطق يحتاج إلى انتباه

يستخدم المتحدث 8 من الصيغ المختصرة، مثل I'm, you're, you've. انطقها بصيغتها القصيرة كما تسمعها.

  • أصوات “sh” و“zh”: congratulations /kənˌɡɹæt͡ʃəˈleɪʃ(ə)nz/, sushi /ˈsuːʃi/

أصوات يجدها متحدثو العربية صعبة:

  • /p/ — ليس /b/: انطقه مع نفخة هواء: deeply /ˈdi(ː)pli/, rapidly /ˈɹæpɪdli/, pursue /pɚˈsu/, implement /ˈɪmpləmənt/, spam /spæm/
  • تتابع الصوامت — لا تضف حركة بينها: congratulations /kənˌɡɹæt͡ʃəˈleɪʃ(ə)nz/, rank /ˈɹæŋk/, implement /ˈɪmpləmənt/, spam /spæm/, defect /ˈdiːfɛkt/

كيف تتدرب بهذا الفيديو

  1. استمع إلى الفيديو كاملًا مرة واحدة دون أن تتكلم، ودوّن الكلمات التي لا تعرفها.
  2. ابدأ بسرعة 0.75×، وردّد جملة جملة، ثم عُد إلى السرعة العادية عندما يصبح الأمر سهلًا.
  3. سجّل صوتك وقارنه بالأصل، مع الانتباه إلى كلمات مثل congratulations, label, pursue.

ما هي تقنية التظليل الصوتي؟

التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
