00:00

I truly think it's insane that I can

00:02

build a powerful machine learning model

00:04

nowadays just by chatting to an AI

00:06

assistant I remember when I first

00:08

started my career doing Predictive

00:10

Analytics was hard really hard with AI

00:14

tools and services on the rise the

00:16

barrier to learning anything really has

00:18

been lowered or at the very least you

00:20

can learn whatever you want quicker if

00:22

you know what tools to use and how to

00:24

use them in the most efficient way in

00:27

today's video I'll show you the simplest

00:30

way I know to build a strong machine

00:32

learning model with no actual coding

00:34

involved I used pcan who have kindly

00:37

also sponsored this video but as always

00:40

all opinions thoughts and Reflections on

00:42

the tool will of course be absolutely of

00:45

my own whether you're a machine learning

00:47

newbie or have some or maybe lots and

00:50

lots of experience training your own

00:51

models I'd encourage you to stick around

00:54

as you'll get to see how simple and

00:56

effective it can be to utilize the

00:58

latest Technologies to build build your

01:00

own machine learning models regardless

01:02

of your experience and I say regardless

01:05

of experience because even though you

01:07

can build precise models with zero

01:10

coding involved you can of course adjust

01:12

your code within pcan I'll show you

01:14

later how so I'll walk you through how I

01:17

built a revenue forecasting model but

01:19

you could obviously predict other things

01:21

like LTV customer turn or winback

01:24

marketing mix or how to up and cross

01:26

sell you can try and build your own

01:28

model the same way by the way ass

01:30

signing up to pcan is completely free

01:32

I'll put the link in the description

01:34

below along with the link to the exact

01:37

data set that I used so after I logged

01:40

in straight away I got to interact with

01:42

the pcan AI assistant the way the

01:44

assistant works is that it asked me some

01:47

guiding questions to help me build my

01:49

machine learning model so I answered the

01:52

first question and told the AI assistant

01:55

that I would like a revenue forecast

01:56

model at the customer level this simply

01:59

means that I want to predict what the

02:01

revenue is for each and every customer

02:04

the assistant is pretty smart as it

02:06

recommended the subject of my prediction

02:09

which was the customer of course and my

02:11

target value which was the revenue and

02:14

all I had to do was to confirm that all

02:17

was good so far then I got another

02:19

guiding question asking me how far into

02:21

the future I'd like to predict the

02:23

revenue for each customer you can choose

02:26

whatever you want really next week month

02:28

quarter or even year but I went with

02:31

probably the most popular future time

02:33

Horizon a month year then the tool asked

02:36

me on what recurring basis I'd like to

02:38

make these Revenue predictions again I

02:41

went with something simplistic here so I

02:43

said that I'd like the frequency of the

02:45

predictions to be monthly I also had the

02:48

options to trigger my predictions based

02:50

on specific events for example when a

02:52

customer makes a purchase but for this

02:54

exercise for this model I chose to go

02:57

with predicting on a monthly basis then

03:00

pcan generated the Predictive Analytics

03:03

question for me all I had to do was to

03:05

confirm that everything still looked

03:07

good and I moved on to connecting to my

03:10

data I uploaded my CSV file which is

03:12

actually a kaggle competition file that

03:14

was cleaned up a bit and as I said

03:16

before the link is in the description

03:18

below so you can go ahead and download

03:21

it and build your own machine learning

03:23

model now of course pcon has a bunch of

03:26

connectors when it comes to connecting

03:28

to your data sets so if you have

03:30

something sitting on SQL servers or with

03:33

popular Cloud providers that's not a

03:36

problem at all pcan is um capable of

03:39

processing lots and lots of information

03:41

as it uses data bricks so you should

03:43

feel confident about loading massive

03:46

data sets after the file upload was

03:48

complete I simply sent it to the chat

03:51

and let the tool do its work with

03:52

analyzing the data the AI assistant

03:55

looked at the schema of the file and

03:57

recommended the column mappings of the

03:59

data set based on the schema for each

04:01

column type I quickly saw what the data

04:03

type was I confirmed that everything

04:06

looked good and moved on this time the

04:09

tool actually figured it out that the

04:11

user ID column was the customer ID the

04:14

amount represented the revenue for each

04:16

transaction and the event time was the

04:19

date or timestamp that I needed again I

04:22

confirmed that everything looked good

04:25

and then I got a summary with my

04:27

predictive question the schema my Target

04:30

table Target value column Target table

04:32

date column and the target entity pcan

04:36

did all the heavy lifting for me in the

04:38

background so now all I had to do was to

04:41

click on generate notebook and then go

04:43

to it to see what's actually in there

04:46

think of the predictive notebook that I

04:47

just generated as the brains or the

04:50

control room of the entire model

04:52

building process I had my SQL queries in

04:56

here that the AI assistant built for me

04:58

you can also see that all of the steps

05:00

were clearly explained each query had a

05:03

name and was actually saved kind of like

05:06

a view so then the next query or sell

05:08

could utilize the data from the query

05:10

above for example the sampled customers

05:13

table could utilize the information from

05:15

the monthly sampling table so Pan's AI

05:18

assistant constructed the core set for

05:20

me by using the answers I provided to

05:23

the guided questions now what do I mean

05:26

by a coret it is the data that allowed

05:28

my model to to know what it needs to

05:30

learn and where it needs to learn from

05:33

so the coret was a final table that

05:35

consisted of all users sample dates and

05:38

the target value which in my case was

05:40

the revenue within 1 month after the

05:42

sample date now the last thing in my

05:45

notebook was the attribute section and

05:47

if you have no idea what this is don't

05:49

worry as I'm going to explain this in a

05:51

very simple way and attribute is the

05:54

data that my model will use to identify

05:57

and find the patterns that will then

05:59

tell my my model what the predictions

06:01

will be so when the model is training

06:03

it's learning the patterns to produce

06:06

the correct Target values long story

06:08

short use the training set to predict

06:11

your Target on an ongoing basis then use

06:14

your model in real life pcan also has

06:16

the option to add more attributes if I

06:18

wanted to so I could have easily added

06:21

more by adding more data whether it was

06:23

just me uploading some files or

06:25

connecting to one of the many databases

06:27

that are supported now of of course if I

06:30

added more data I could have just used

06:31

the AI assistant to replace my already

06:34

existing query so that it runs on my new

06:37

data set again no coding involved just

06:40

pure AI magic I wanted to keep my model

06:43

nice and light so I chose not to add any

06:45

more attributes I just went with the one

06:48

I already had my notebook had everything

06:51

I needed to train my model using the

06:53

data set I uploaded into the chat

06:55

earlier I hit run all which ran all of

06:58

my SQL queries

07:00

then I trained my model now I had two

07:03

options fastest which is by no surprise

07:06

fast as it only takes about 10 to 30

07:08

minutes to train a model and production

07:10

quality which provides better

07:12

performance but takes a little longer to

07:14

train I know it says several hours here

07:17

but my model was actually built in about

07:19

an hour or so the time it takes will of

07:22

course depend on how complex your

07:23

machine learning model is so once I hit

07:26

train model P can quickly rans some data

07:29

valid ations to check that my data was

07:30

actually fit for building a predictive

07:33

model and that was it I sat back and

07:35

waited for about an hour and I had my

07:37

Model results with some cool metrics and

07:40

visualizations that helped me to gauge

07:42

how good my model actually was I could

07:45

see on the model evaluation tab under

07:48

model performance that my model was very

07:51

precise meaning the model was very close

07:53

to the actual values the pan platform

07:56

has a really powerful engine behind it

07:58

hence the really good result results

07:59

clearly their data teams know what

08:02

they're doing now the model evaluation

08:04

tab has a bunch of other metrics as well

08:07

and I won't go through all of them but I

08:09

will highlight column importance which

08:11

was very useful to know in my model I

08:14

could see that the amount column was by

08:16

far the top contributing column to the

08:19

model predictions which makes sense

08:22

another helpful tab I used for

08:24

interpreting my Model results was the

08:26

model output tab I could quickly see

08:29

what the prediction was for each user

08:31

for each month I'm getting more and more

08:33

used to how much and how fast AI can do

08:35

things but at times it is still

08:37

mindboggling to me that it allows me to

08:40

do such difficult tasks like building a

08:42

strong machine learning model just by

08:44

interacting with an AI chat assistant

08:47

now does this mean that coding is

08:49

useless absolutely not the ability to

08:53

read write understand and interpret code

08:55

is still very very important in my

08:57

opinion just think of this who can

09:00

develop the better machine learning

09:01

model in a shorter time frame the person

09:04

who knows how to use the latest AI tools

09:06

but has no real technical expertise or

09:09

the person who also knows how to use the

09:12

latest AI tools and has extremely strong

09:15

technical skills surely the person with

09:17

the strong technical skills will be able

09:19

to fine-tune the model better and faster

09:21

using the same AI tools compared to the

09:24

person with little technical expertise

09:27

not to mention all of the underlying

09:29

math and statistical knowledge that is

09:31

of course also essential to building

09:33

good machine learning models anyway I'm

09:36

going to end this video here if you

09:38

enjoy content like this make sure to

09:41

check out some of my other videos right
