hi everyone welcome to hedgehog hollow on

LDRs inspiration week I hope you enjoyed

our new-release close up earlier in the

week and today I'm going to be sharing

with you how to use the Builder card

dies so these are a really neat

invention from LDRs so inside of here

you have a number of dies in this one

there's 11 pieces and I'm going to show

you first of all how to cut your card

base so the idea of the Builder card is

that they have an area that does not cut

that you can then create shaped card

bases with so this is a piece of brown

12 by 12 card stock that I cut in half

width ways and I'm gonna put my die on

here because it looks like the camera is

having issue just focusing on that brown

cardstock so you can see here and this

was a six inch wide piece 12 inches long

that I've cut down ready to use my build

a card on and so I'm gonna pop my piece

down here I already have my die clay and

I'm gonna be using my Gemini Junya it's

my favorite die-cutting machine two

years and I'm gonna grab a piece of

masking tape that I had ready to go and

I what I'm gonna do is I'm gonna tape

this in place so if you look at the

reverse the die this area here

doesn't actually cut so you want to

align this up with the edge of your card

and I'm going to stick this down or I

want it to cut and what it's gonna do is

it's going to cut us a shaped card base

I'm gonna move it down just a smidge so

that we make sure we have that top and

bottom and so not by not cutting on that

fold we're gonna end up with a pumpkin

shaped card which i think is gonna be a

really good fun so I'm going to just run

this through my Gemini and so what you

can see is I have a really neat pumpkin

shaped card so I have my build a card

that is pumpkin shaped and you can

actually move this a little bit closer

if you want to so what you want to make

sure I tend to just add this on because

I find that a thicker piece just gives

me a better

and stronger fold and so I make sure

these two little teeth line up with that

fold on the edge of my cardstock you can

actually move it out a little bit more

if you wanted to because it doesn't have

any cut area in here so you can line it

up however you want to cut it also

depends how you're going to be

decorating your card as well so we are

also going to cut out our decorative

pieces here and I'm going to lift this

one thing and I'm going to be using some

of the happy for paper so this is the

Becky Pierce paper pack that I showed

you lots and lots of pretty designs and

the LDRs paper packs have a really fun

kind of feel to them but they're also

thicker they're almost like a thin

cardstock so I'm going to send to this

up how I want my pieces to look so I'm

going to make sure that I have a few of

the different critters on this you can

line it up however you would like to and

I'm going to pop this again through my

Gemini machine and so here I have my

pretty pumpkin piece which also has a

little bit of a beveled edge to it

you'll also notice that my card base has

that same pretty beveled edge it just

adds a nice finishing touch and of

course this piece is now going to fit

over our card base perfectly so I'm just

gonna add some tape runner you're gonna

add on some tape runner here this is the

scrapbook com1 this is a great adhesive

as is the tonic funky tape runner and so

I'm going to add that on to my card base

here and so it gives me a really nice

border for adding that on and on that

top piece I'm still going to add some

tape

and so if I'm adding tape to a tricky

area the glass tonight is perfect for

that because I can use my tape runner as

normal and then pull it away and the

tape only add ears to the paper anything

left over is on here and it's just super

easy I just rub it off like that and I

knew what I'm going to do is add a

really simple sentiment to this I'm

going to use some white cardstock and my

Misti and I'm going to use the happy

full sentiments and they're really

pretty sentiments that will just kind of

stand alone really nicely and this is

just a piece of white stamping cardstock

and I'm going to tie this together with

the new ink cubes so these are the same

wonderful LDRs hybrid inks that are now

in cube format so if you are challenged

by space constraints these are perfect

and I store mine in one of the deflector

washi tape storage units because they

just work absolutely perfectly for your

ink cubes so you can see they're easy

peasy to stamp out and because this is a

hybrid ink if I wanted to add any color

to it I don't need to because it's a

detailed stamp I can do that without

having to worry about it because I can

use watercolor or I can use

alcohol-based markers I'm not going to

have any problems and now when I go to

trim this I line up one part of the

image using the guide that's actually in

my trimmer so I know that that guide is

straight and so I cut side one and then

I use that straight edge against the

guide and then it's like two and so I

just keep working around and that

squares up my piece of paper to my

sentiment it's a really easy way to do

that

on the final side there and I'm gonna

bat it on some pretty cardstock so I'm

gonna bat it on some of the wicked

Winnie cardstock and I think I'm gonna

use some orange let's kind of use up

some of that pretty orange so again this

because this piece is not measured in

any way I line up my sentiment in that

corner there and they're very easy for

me to start cutting because I know that

two of my sides were already matted

pretty perfectly and so I can just trim

this down to even up all the way around

so you can see that how simple that was

to matter and we're just gonna add this

onto our little piece here and I'm gonna

use some foam pads these platonic craft

perfect ones I happen to just have these

two hand they are really nice as well

because they come in a big cube size so

you can cut these down with your

nonstick scissors or if you have a

larger sentiment you can just pop one

right on there I tend to use two because

I like a little bit more height depends

if you're putting them through the mail

or not you can choose what height you

would like your piece to be and I'm

gonna pop it on a little pretty angle

but that is how easy our build a card

dies are you've got lots of trimming

pieces if you want to use those on your

card it will stand up for you as well

it's got a nice base on there so I hope

you've enjoyed this quick tutorial it's

just a 10 minute quickie card that you

can also make at home using those new

supplies to the LDRs release don't

-------------------------------------------

Build a Neural Net in 25 Lines of Python - Duration: 5:55.

What is up guys, it's Adam back with another video and today we will be building a simple neural network in Python

But before we get started

I'd like to give a shout out to at I am Trask for writing the code used in this video

I'll give a link in the description to his blog post on neural nets without further ado. Let's get started

Alright guys, so I am currently an Adam text editor and we are going to start our Python file by importing numpy as MP

Next we're going to define our sigmoid function which in short if you don't understand what that is

It'll basically make all of our weights into one scale that goes from 0 to 1

all we are really doing is implementing the math that you see on screen right now, so

This function will have two parameters X and derivative

which will be set by default as false now if

Drivel to true we are going to return x times 1

Minus X and then outside of that if statement we will return 1 over 1 plus NP

exp for exponent 2 negative X

Now that our sigmoid function is defined. Let's write in the X and y components

For our neural net to train on so first we will set X as equal to NP or a open brackets

0 0 1 0

1 1

101 and

finally 1 1 1 so this is just going to be our input data and

now for the corresponding Y values y equals NPR a

0 0 1 1 dot T capital T that is for transpose so that we can use matrix

multiplication

So just to recap our neural net is trying to predict what the value of y is based on X

So if X is equal to 0 0 1 as it is in the first training sample

the output should be 0 because that is what the course why value for the x-component is

Next we are going to initialize a seed value with NP random

This will mean that the neural net will initialize the same random value every time

This is a good practice to always use and it will help a lot with debugging

Now we are going to make our synapse which if you know anything about neurons in our brain

It's something that connects two neurons to each other since we only have one hidden layer

We are only connecting the input to the output of our network

the input being our three x values and the output being our 1 Y value so

We will set a variable called sin 0 equal to 2 times MP dot random

3 comma 1

minus 1

This is for the 3 input X values and the 1 Y value

All right

so finally we are going to start training our network to do this start a for loop and iterate through it as many times as

You like a good number to start with for now will be?

10,000 if

This number is too low the network won't be able to update the weights enough for them to make the neural network work

Well, if it is too high, we will over fit our data making the neural net not work. Well with new data

Ok, so in our for loop layer 0 or the input layer is set to X and layer 1 or the output layer is set

to the sigmoid of NP dot dot which is for matrix multiplication l 0 sin 0

So basically we are multiplying the input layer by our synapse and setting it in a value from 0 to 1

Now, let's set a variable called L

1 underscore error

Which will compare our L 1 value to the actual Y value as we iterate through our loop this variable should get smaller and smaller

As our neural net gets more accurate

Next let's set a variable called l1 Delta to the l1 error times the sigmoid of l1

With the deriv equals true so that it runs that if statement we defined earlier

This will help all neural net not become too overconfident in its answers

Now, let's make synapse zero two plus equal NP

dot layer zero dot transpose and l1 Delta

This line will update the weights of our network

Finally outside of our for loop. Let's print out layer one

So our neural net is now basically done. Let's run it and see what the results are

You can see our network is pretty accurate

It thinks the first two X values are probably zero and then the last two are probably one

Congratulations, you just built your first neural network

So if you didn't understand anything that's going on in this code. That's okay

There's so much theory behind a lot of these concepts and it takes time to fully

Understand everything if you want to continue working with neural nets and machine learning

Please comment down below and I will also do a video on how I'm learning machine learning personally

Also, once again, thank you to at ion traps for writing the original code for this video

I think it's a really good introduction to neural nets. You can check them out below
