play00:00

all you need to learn machine learning

play00:01

in 2024 is a laptop and a list of the

play00:05

steps you need to take I'm a student

play00:07

researcher working for an ex meta

play00:09

professor and have had interviews with

play00:11

Google deepmind Amazon and other cool

play00:13

companies but it took me over 3 years to

play00:16

get to this point so today I will share

play00:18

how I would learn machine learning if I

play00:20

could start over by revealing the six

play00:23

key steps you need to take let's get

play00:25

going in general all these steps don't

play00:28

have to be strictly completed in any

play00:30

particular order but I would not start

play00:32

with the final and arguably most

play00:34

important step that said what I do

play00:36

highly recommend is to start with

play00:38

learning the basics of python python is

play00:41

the programming language used by pretty

play00:42

much everyone to work on machine

play00:44

learning and every other step on this

play00:46

list Builds on top of it this mainly

play00:48

applies to beginners that don't know

play00:50

what a list or a dictionary are and that

play00:53

don't know how to write a simple if else

play00:55

statement or a for loop I would even go

play00:57

as far as saying you need to learn on

play01:00

what a list comprehension and what class

play01:02

inheritance are and honestly I don't

play01:04

know what else to say than just type in

play01:07

Python tutorial or course on YouTube or

play01:10

Google and get started there's so much

play01:12

amazing free content out there but you

play01:14

should always keep in Minds to actively

play01:16

code along the tutorial enjoy getting

play01:19

into machine learning with python but

play01:21

don't go too in depth this lets you

play01:23

start with a fun experience because at

play01:25

some point you will also have to learn

play01:28

maths now you could argue that you don't

play01:31

need mouths because so much is already

play01:33

automated and taken care of by cool

play01:35

python libraries which is true but you

play01:38

will need to know all the fundamentals

play01:40

of calculus linear algebra and

play01:42

probability Theory to understand pretty

play01:44

much any machine learning approach that

play01:47

said you really don't need complex maths

play01:49

most of the maths is high school or

play01:51

entry-level College maths like you just

play01:54

need to understand what the derivative

play01:56

of a function is and how to compute it

play01:58

you need to know what a matrix is is and

play02:00

how the dot product works there again

play02:02

are amazing resources out there that are

play02:04

free like these courses right here or a

play02:07

website called Can Academy I mean you

play02:09

can even learn most of what you need on

play02:11

brilliant.org sadly not sponsored or you

play02:14

just go to college and take the

play02:15

mandatory maths classes for any

play02:17

engineering major I'll tell you about my

play02:19

absolute favorite resource for learning

play02:21

the fundamental Maths for new networks

play02:24

after we cover the next important steps

play02:26

this already shows you that you don't

play02:28

need to hustle through all the courses

play02:30

there are in the beginning in fact I

play02:32

wouldn't even recommend that because it

play02:34

can be very frustrating and just not fun

play02:36

whenever you don't understand some maths

play02:38

later on you can always revisit it by

play02:41

just Googling learn the basics and then

play02:43

continue on to the next fun step

play02:46

learning about the ml developer stack so

play02:48

now you know the basics of python and if

play02:51

you haven't already can learn some basic

play02:53

tools like Jupiter notebooks and

play02:55

libraries like pandas numpy and matplot

play02:58

lip numpy is a library for doing mouths

play03:00

with matrices or arrays it's a great

play03:02

starting point because you can now

play03:04

implement the mouths that you just

play03:05

learned about and see how simple it is

play03:08

to compute a DOT product between two

play03:09

matrices met plot lip is a tool for

play03:12

visualizing data and graphs and just

play03:14

seeing what maths you are doing and in

play03:17

my opinion at least visualizing stuff is

play03:19

fun and just very useful finally pandas

play03:22

is a great tool for dealing with data

play03:24

that is in tabular format a lot of

play03:26

machine learning problems deal with

play03:27

tabular data and pandas lets you again

play03:30

very easily manipulate those and

play03:32

visualize the tables all those libraries

play03:34

also work very well with jupyter

play03:36

notebooks and are an essential part of

play03:38

learning machine learning as you will

play03:40

see by getting to know those Frameworks

play03:42

you will automatically improve your

play03:43

overall practical Python and ml skills

play03:46

but again only focus on the basics by

play03:49

following a few tutorials later when

play03:52

working on projects you'll really get to

play03:54

know the libraries so now let's get back

play03:56

to some Theory and finally actually

play03:58

learn about machine learning and deep

play04:00

learning okay up until now everything

play04:02

should honestly not take too long

play04:05

perhaps a few weeks depending on how

play04:07

much time you put in and at what level

play04:09

you already are but the ml courses I

play04:11

will now recommend do take some time the

play04:13

best and probably most famous machine

play04:15

learning course or collection of courses

play04:18

is the machine learning specialization

play04:20

by Andrew Nung the cool thing is that

play04:22

you here already get to know some

play04:23

machine learning Frameworks like psyched

play04:25

learn and tensorflow well I do have to

play04:28

admit I personally prefer and would

play04:30

recommend py Toge but learning one

play04:32

framework pretty much lets you already

play04:34

quickly adapt to the other one this

play04:36

course is absolute gold and it's free

play04:40

although this is the beginner course it

play04:41

is still very important they here teach

play04:44

a lot of classical ml Concepts and those

play04:47

are the things you need to be able to

play04:48

answer quite easily in ml interviews now

play04:51

remember when I teased my favorite

play04:53

resource for learning maths in neural

play04:55

networks well after learning about those

play04:57

in Andrew's course I would watch Andre

play04:59

kathi's neural network series he here

play05:02

implements a simple NLP model from the

play05:04

ground up and goes all the way up to a

play05:07

transform model he also goes through all

play05:09

the mths of back propagation and so on I

play05:11

cannot recommend this series enough

play05:13

since in Andrew NS and Andre kath's

play05:16

courses you already get some practical

play05:18

experience with the taught ml Concepts I

play05:20

would then continue on to the next more

play05:23

advanced and practical course the Deep

play05:25

learning specialization this course

play05:27

focuses more on implementing and

play05:29

training new Nets and the absolutely

play05:32

amazing thing here is that they also

play05:34

include hugging face which is a library

play05:36

that you pretty much cannot avoid it's

play05:38

really amazing and if you feel like this

play05:40

course doesn't teach you enough about

play05:42

hugging face you can also just go

play05:44

through the hugging face NLP course

play05:45

directly there you also learn even more

play05:47

advanced concepts in NLP well if you are

play05:50

interested in NLP that is so yeah those

play05:53

are the two or perhaps even three

play05:55

courses I would take and recommend by

play05:57

now you have learned a lot and worked on

play05:59

several smaller projects or rather

play06:01

tutorials now it's time to actually get

play06:04

your hands dirty and work on real

play06:05

projects I honestly think you here learn

play06:07

the most and there are two things I

play06:09

would work on first I would go to kagle

play06:12

and just work on challenges there are

play06:14

many available for any level try not to

play06:17

underestimate the complexity and start

play06:19

with simpler challenges so you don't get

play06:21

frustrated and demotivated and if you do

play06:24

take on more difficult ones that also

play06:26

come with prize money don't expect to

play06:28

win one it's really difficult to get to

play06:31

that point and you also need a lot of

play06:33

compute so okay after working on kegle

play06:36

challenges comes my final and favorite

play06:38

type of project to work on

play06:40

reimplementing a paper and recreating

play06:42

the results this is challenging and you

play06:44

will learn a lot and most importantly

play06:46

this type of project will definitely

play06:48

help you stand out on your ml

play06:49

application that said there are a few

play06:51

other simpler ways to stand out that you

play06:54

can already get started during your

play06:55

learning process so I'm sure you might

play06:57

want to watch this video right here

play06:59

where I reveal those techniques and tips

play07:03

bye-bye
