Machine learning for the kids with Scratch || Machine Learning for kids ||Day 1

[Music] hello hello an audible hello am i audible to everyone can you hear me okay so we will wait for one or two minutes okay because we have one or two minute time after that we will start our class okay so good afternoon everyone how are you all how was your day i hope you are really good okay so today we are going to learn about first thing coding for kids okay so first we will see what is coding why we are using the coding okay see for human as we know for human being we have it suppose we have english language we have hindi language we have spanish we have german right so for computer also we have several languages okay because a computer is the machine and computer don't understand our languages okay even computer don't know what is english so if you want to talk with your computer if you want to give any instruction to your computer so we can do with the help of coding okay so we can say whatever we are searching in the computer whatever suppose if you want to shut down your computer if you want to start your computer okay so this all are the instruction to our computer even in mobile phone also we have the same thing like suppose if you want to start your youtube or if you want to start your facebook instagram or anything okay so how we will do that with the help of our coding we can do all these things so we can say with the help of coding we can create any animation we can create any mobile apps we can create any games so this all are the coding okay so understood everyone what is coding okay so now we will start our main part for today machine learning okay so this machine learning is for the kids okay like the age group five two 18 20 we can say okay so first of all what is machine learning anybody know what is machine learning anyone have any idea what is machine learning okay so first thing what is machine learning before machine learning we will see what is artificial intelligence okay see we have some machine do you know we have our automatic car yes all of you so in that we have to give some intelligence to that car right even if you will take your washing machine in the washing machine if you will set anything like if you want to increase the temperature right if you want to increase any mode or anything so for that we will require some intelligence to our machine right so with the help of artificial intelligence we can do that so we can say in general artificial intelligence is your set of program okay so now see we have some example which is related to your artificial intelligence okay do you know we have alexa we have siri yes all of you so why we are using alexa even you can see like hey alexa please play this song or hey alexa please do this thing right so you are giving the command by using text by using your speech right internally how alexa is finding all these things just because of intelligence see we are a human being so we have intelligence right but how you will intelligent your machine machine in the sense like your computer like your laptop your mobile phone or we can say the machine like your any robots okay so with the help of our artificial intelligence with the help of machine learning we can give all these commands okay see we have some image recognization okay like if you will open the camera do you know we have snapchat filter like you can uh put any dog face or you can put any specs like that so how we can do all this thing with the help of machine learning okay but so now we will see the next part how this is possible okay so we can say this is possible with the help of our machine learning okay and here we have some data we have some algorithms so by using that data by using some algorithm by using some training data we can do all these things okay so now i will explain you how you will do this okay let me show you so now we will just search so what you have to search here you need to open your google chrome what you can do you can write all these steps in your notebook and after the class you can just perform this okay so see here you need to just search for machine learning for the kids okay you have to press your enter button you will get your first link which is see https scholar machine learning for the kids dot co dot uk okay so this website is from the uk and we are using this website to create our program which is related to our machine learning okay so over here we need to just click on get started so see you are a first time user okay so you need to sign up so once you will click on sign up it will ask you a parent teacher or leader of coding club so you can select your first option over here you have to just click on sign up once you will click on sign up it will ask you your email id your password everything so put your email id and password so you are able to create your account here okay so what i will do for today or is if you don't want to create your account you need to just click on try it now okay so once you will click on try it now you will get this interface which is your machine learning project okay so today we are going to create about cat and dog project so cat and dog project means what we will take some cat image we will take some dog image so based on our coding based on our training data what will happen machine automatically will recognize who is cat and who is stock okay because we have to give some intelligence to our machine okay so how we will do this you need to click on add a new project see this one over here we have to write our project name so i want to write my project name cat and dog you can write any project name here after that the recognization type see here we have four types of recognization type okay we have text we have images we have numbers we have sounds okay so for today we want to recognize the image right see we have some cat image we have some dog image right so if you want you need to take a images here so once you will take a image you need to click on create button so understood you have to write your project name and you need to select your recognization type asa images yes everywhere after that we need to click on create button so once you will click on create button it will create one project for you as you can see we have cat and dog project and what is your recognization type this is image now you need to first click here what will happen you will get three things so first we have to train our machine right suppose if you want to uh to the performance like your stage performance in a dance so first you have to give some training to yourself right so here also if you want to create a machine who will recognize like who is stock and who is cat so first you have to train your machine right so how you will give the training you need to click on this train button okay once you will click on the train button you will get see click on the plus button on the right add your first bucket and here you will get add new label so we want cat and dog so you need to click on add new label your first label is scat click on add so here you will get your chart label after that your second label add to label here we have dog so you need to write talk click on add okay see we have cat label we have dog label right now after that what we have to do we have to take some images which is related to your cat we have to take some images which is related to the dog okay so here we have three option so what you can do either you can draw the cat shape okay so here you can draw the cat or is what we can do we can directly download the images from the internet okay so how we will do that so first i will minimize this okay after that see you have to take your screen like this and you need to take one more screen suppose i want to add one more google chrome you have to put your screen here so this is your second screen see we have two screen here right so in my second screen i will search for dock or first we have a cab so i will search for cat and you need to just go to the images so here you will get some cat image right so what we have to do we need to just drag and drop the image here suppose this is my first image wait it is loading okay so drag and drop your first image here see this is your first image i want one more image here so drag and drop your second image after that so at least we will require six to seven images here we can see we have a different types of cat we have colors like a black color white color so whatever color you want you can add your see we have this is our fourth image then we have our fifth image after that we can add this one also this one also so see how total how many in how many images we have now one two three four five six seven now same we will add some images in doc so what we have to do we need to just search for doc you will get some images so whatever image you want you can add yes so this is my first image this one is the second one if you will scroll down you will get lots of docsy third one fourth one i want to add this one as soon i want to add this black box also see we have some images so how many images you want you can add here so minimum you can add five to six images right so now see in our training data we have all these images right cat image stock image so again you have to go to back to your project see we already trained our model in the training part we have to label cat label talk label in the cat label we have some images which is related to your cat in the dog label we have some dog images right now you need to back to your project okay so you understood how you will train your model you have to specify some image here okay after that we will see how you will test your model how you will do loan and test okay so for that we need to click on learn and test so this is our second step in machine learning of model machine learning model okay so see what we have here what you done in now what you done here you have collected examples of images for a computer to use to recognize when images are cat or dog okay after that what we collected here seven examples of cat and nine examples of talk right after that what is the next step ready to start the computer training okay so you need to click on train new machine learning model okay so once you will click on train new machine learning model it means we are checking like whatever we added here that is correct or wrong okay so it will take around 30 to 40 second based on your internet speed just wait for a moment after that we have to open this project in our scratch okay so see everything is perfect till now so here we can test with our webcam or we can text with drawing so what you can do in the webcam you can just click on this your camera will start you can if you have a cat or dog you can just click the photo of cat and dog and based on that automatically that will recognize whether that is cat or talk okay now you need to again back to your project now we have to click on make so all of you you understood first step you have to train your model second step you have to test your model whether what you did that is correct or not after that you need to click on make so once you will click on make over here we have three option either you can open in your scratch three all else you can do in your python or else you can do you in your app inventor okay so for now we will open this in a scratch tree why because already we know what is scratch because in our previous class i told you what is scratch right so we need to click on scratch 3 everywhere after that it will show you one button which is open in scratch 3 once you will click on open in scratch 3 now it will give you scratch 3 user interface ok now all of you do you know what is scratch if you remember i took 10 days scratch course right yes okay so see in your scratch you will get one additional block which is your machine learning for the lack of whatever you did here like a we have our cat model we have a dog model so that you will get here okay now what we have to do now we have to add some images which is your cat image we will add some so based on your machine learning whatever you given in the training phase based on that it will recognize that images chat image or doc image okay so first thing we have to add one backdrop here so what i will do i will click on choose a backdrop i want to do the painting here okay so what i will do i will take one color suppose red color you can draw we have to divide this okay so this is my first part you can write all these steps okay and after that class you have to perform this and in next sunday you have to show me okay because in next sunday also i will take a class okay see i want this color after that you can just change your color and here we have to give some dividation like this so this is my second part we can add like this here also see then what we want i want to write one text here which is in black color like this is my cat and the second part here we have a dock you understood how you will create your backdrop after that we have to add some sprite which is related to the cat and which is related to the dog okay so click on choose a sprite we can just search for dog so how many dogs we have we have one dog so this is my first one so for this talk we have to add some costume okay so see this is our first sprite how you will add a costume you need to click on costume from here see already we have four costumes here so we need to click on upload costume or else if you want you can just search here choose a costume suppose we want cat so you need to click on cat we have our first cat again choose a costume search for dog just randomly you can add some cat and dog images okay so we have this stock again we can choose a costume so you need to search for cat or is we have next option what we can do we can just search for cat image go to the images after that suppose if you want to download this image and you want to use this image you can just right click click on save images as click on save okay now come to your project what we can do choose a costume so if you want to choose existing costume you need to click on choose a costume or else what we have our next option upload costume so wait so this is my cat open you will get a cat here okay from here we can decrease the size like us up i want only 50. so understood how you will add a sprite see we added our backdrop and we added our sprite okay what is our next part we have to start our coding part right very good very good yogesh always we have to start from the event perfect you remember that right good so how we will start our coding we need to just click on event so when flag is clicked okay so when flag is clicked what we want here we want to go to the middle position like zero comma zero so zero and zero is our middle position okay which is the middle part okay so we want to go here so what we have to do when flag is split so where you will go where you will get your go to x and y inside the motion we have go to x and y which is 0 and 0 okay after that what we want we want to repeat this right like if the image is stat so what will happen this card will come to here if this is stop it will come here okay so we have to take a repeat where we have this repeat in the control we have our repeat see okay so here we need to take our if condition if see if this image like the costume image is equal to equal to your cat so where you will get that first we need to go to operator take this equals to sign okay now we have to just come to our machine learning if your recognization image right this if your recognization image instead of this image we need to take our costume image which is this because we added the costume here right yes so if that is equal to equal to your cat means this okay so what will happen we have to say this is the cat okay where you will get your say block you will get inside the looks here instead of hello we have to write this is cat okay what is this is scat for 2 second for example after that it has to be go to some position so suppose we have to take this position in the x minus 129 in the y minus eight okay so again you have to come to the motion take this go to x and y and here i will take this here now after that we have to show this cat so you need to just go to the looks you will get your show block here all of you remember where you will get every block and after waiting some second now we want another image right so for that you need to go to control you have to wait for suppose one second then we have to broadcast one message so where we will get our broadcast inside the event we have to broadcast suppose message one same we have to do for dog also so how we will do the dog what i will do i will right click here and you can just duplicate this and you need to put this block here so what is this if your recognization costume instead of cat we will take dog now so here we have to add the top if that is stock so it will say this is dock and we will take this position so what is this suppose 90 and 7 so here we will write 90 instead of y we will write 7 okay and it will broadcast one message now see if i will click on flap what will happen see this is cat so you will get this position see this is working but here we don't have our next image right so for that what we have to do we have to just change the costume okay so how we will change the costume what is the code for that means see here we have a broadcast message one so once we will receive that broadcast means once when i receive my message word i have to change the next costume so here you will get your next costume and again it will go to your origin position means go to 0 and 0 now see 0 and 0 now see what will happen this is cat perfect so you will get in see this is stock with the help of your machine learning now see this is classified this is cat this is stock okay so we can do all the
