WEBVTT

00:00.920 --> 00:06.260
And it's this time again, when we look at the podium of how our models are performing across the board.

00:06.260 --> 00:12.050
You already know the answer, but we should look at it anyway and and and have a giggle.

00:12.320 --> 00:17.900
Uh, so we first look at the constant model that just guesses the average value from the training data

00:17.930 --> 00:18.590
set.

00:18.950 --> 00:22.880
And if we look at that number, it was 146.

00:23.000 --> 00:26.150
It's looking distinctly lower in here right now.

00:26.150 --> 00:28.070
And I think you probably know why.

00:28.370 --> 00:34.100
Uh, then we looked at a traditional machine learning model that was able to beat the average, which

00:34.100 --> 00:36.260
we would hope it would, but not by masses.

00:36.470 --> 00:42.050
Uh, we looked at the random forest approach, which was the best of the traditional machine learning

00:42.050 --> 00:44.510
approaches coming in at 97.

00:44.510 --> 00:51.140
We did compare it with a human being and showed that human could beat the basic, simple features,

00:51.140 --> 00:53.870
but was beaten by random forest model.

00:54.140 --> 01:00.290
Uh, GPT four zero was the best of the various frontier models we looked at, and absolutely crushed

01:00.290 --> 01:04.610
it with 76 way outperforming this human.

01:04.820 --> 01:13.600
And then today we've looked at the, uh, fine tuned bass llama, 3.18 billion parameters quantized

01:13.600 --> 01:15.310
all the way down to four bits.

01:15.430 --> 01:21.190
Uh, and we saw that that was at 396, devastatingly bad.

01:21.280 --> 01:29.290
Uh, and it was only slightly better when we quantized to eight bits, instead coming in at $301 of

01:29.290 --> 01:29.950
error.

01:30.160 --> 01:36.550
Uh, so clearly we're off to a bad start with llama 3.1, but in some ways that's exciting because the

01:36.550 --> 01:37.780
challenge is on.

01:37.870 --> 01:45.640
Uh, we've got the the model here ready for us to try and explore how we can make it better.

01:45.640 --> 01:53.410
And our target is to try and be competitive with a model like GPT four, which is, you know, has trillions

01:53.410 --> 01:54.460
of parameters.

01:54.460 --> 01:59.530
If we can be competitive with that in this particular task, and we can do it with an open source model

01:59.530 --> 02:04.240
that's for free, then we have achieved a great thing.

02:04.240 --> 02:05.080
Okay.

02:05.110 --> 02:11.690
And so in summary, at this point, at this juncture, you have reached 80% of your way in this journey

02:11.690 --> 02:14.120
and that is absolutely fantastic.

02:14.120 --> 02:15.260
I'm so happy you.

02:15.290 --> 02:16.190
Are sticking at it.

02:16.190 --> 02:17.660
I'm so happy you're here.

02:17.660 --> 02:20.690
I got to tell you, the 20% that's still to come.

02:20.690 --> 02:21.740
It's the best.

02:21.740 --> 02:23.060
It is the best.

02:23.090 --> 02:25.820
The juiciest content is what's to come.

02:25.820 --> 02:27.860
As we look at training this model.

02:27.860 --> 02:32.540
And then in the finale next week, we really put everything together.

02:32.540 --> 02:35.210
I mean, it's just it's going to be a crescendo.

02:35.210 --> 02:37.160
It's going to get better and better.

02:37.160 --> 02:38.300
Hang in there.

02:38.330 --> 02:40.250
All of the good stuff is to come.

02:40.250 --> 02:44.870
So what we're doing next time, there's some more hyperparameters.

02:44.870 --> 02:49.760
I know that these hyperparameters can be a bit grueling, but this is where the really important stuff

02:49.760 --> 02:50.390
is learned.

02:50.390 --> 02:54.530
So there's some hyperparameters that control training that I'll explain to you.

02:54.560 --> 03:00.020
We're then going to set up something called a supervised fine tuning SFT trainer, which is where it

03:00.020 --> 03:00.830
all happens.

03:00.830 --> 03:03.650
And then we're going to kick off training.

03:03.650 --> 03:10.970
You're going to be training your own proprietary large language model, uh, based on, uh, llama 3.1

03:10.970 --> 03:11.720
based model.

03:11.720 --> 03:15.320
And we're going to be doing it, uh, in the next session.

03:15.320 --> 03:17.210
So I will see you there.
