ProCodeCG – BDV – Technical Series #8 – Machine Learning Object Detection with YOLO – 8 April 2019 – Day #3 #4

We finished the #3 and #4 session today 😉

We explored both darknet and darkflow object detection today. This is the example of darkflow object video with camera

We tried very hard to make either darknet or darkflow works on each computer

Some of the results today

 

The project today is to create our own dataset of 3 kind of instant noodle: Indomie, Supermie and MiSedap. We had to download the picture, put box around it and label it, make the system learn and then see if it can classify or detect the object

At the end of the class we were still figuring out about how to get the new weights to train our dataset. The process took lots of time, we had to continue the rest at home 🙂

ProCodeCG – BDV – Technical Series #8 – Machine Learning Object Detection with YOLO – 1 April 2019 – Day #1

Our training about Deep Learning and YOLO for object detection, Day #1 😉

Like usual, the first day of the workshop is about basic theories and then installing saga 🙂

Our target for today is installing Python, virtualenv, tensorflow, requests, numpy, cython, opencv, and nmv

but since there are lots of operating systems and configurations, we could go as far as installing virtualenv and tensorflow and for some: hello world in tensorflow

The complexity of the tasks is shown here 😀 *look at the faces LOL

Next week we will learn about object detection theories and continue the installations 😉

ProCodeCG Kids Coding Camp – Python Programming – Day #3

The last day of Kids Python Programming Coding Camp 🙂

Veyzha actually learned two things today: Python programming and GameMaker 😀 Veyzha had successfully made a simple calculator GUI in Python and then helped Kenzie to do the same thing 🙂

Kenzie finished the task to create a simple calculator with GUI and explore simple artificial intelligence in Python 😉

Vius had completed lots of difficult challenges. Including creating a pizza restaurant form that can calculate the price and the discount for different kind of pizzas and different kind of toppings for each kind of pizzas 😀

Ren finished task very quickly today 🙂 He went through encryption, decryption, virus, antivirus and encryption-decryption virus then simple artificial intelligence 😀

Ren helped Veyzha to debug the program 😉

 

Capt. Faris created his own applicable app with Android Studio 😀 Awesome 🙂

Our incredible Python Programmers 😉 Veyzha had to leave earlier so there were only 3 of them at the end of the class 🙂

Glad to be able to produce another class of Python Programmers! See you again kids, now you have the skills most people want so bad 🙂

ProCodeCG Kids Regular Coding Class – 10 Mar 2018

An extraordinary regular thing for us every Saturday: kids coding class 😉

Hello Capt. Awa 😉

Awa was really busy working on his vending machine project

the schematic

components

Awa is going to present this work in Malaysia very soon 🙂

Well, even a Captain needs a break 😀 *Awa having breakfast 😀

Fathan, is a determined game maker 🙂

Fathan worked for three straight hours improving this game 🙂

Fathan kept adding things to the game, and tried different ways to do things like displaying scores with two different ways 🙂

A very impressive game 🙂 It has every components required in this kind of game 😉

Sam is a focus fast learner

The first sprite

the first moves

and the game grew so quickly into a full featured one 🙂

Sam is certainly know how to create interesting games 🙂

Capt. Faris had loads of work and research to do

Faris was given a task to parse data crawled from instagram 🙂

And prepare other captain to catch up with the research 🙂

Aidia 🙂 A bubbly, cheerful and passionate little girl 🙂

Aidia likes to create things in Minecraft

 

Aidia was given a project to create a 2 storied house with elevator 🙂

Aidia always pays attention to little details 🙂

Danen was also working on his game and improving them 🙂 He worked on several games at the same time 🙂

Danen also discussed with Capt. Awa about the game

And produced something like this LOL

Vian (left) and Ain (right) were still doing the same Minecraft project

Vian was responsible to help Aidia learning more about Minecraft commands 😉

Aaaand, we had Capt. Malik back!!!

Capt. Faris (left) helped Capt. Malik to install things required to catch up with our research and projects 😉

Two of the best captains of ProCodeCG 😉

Malik was going to be help Faris to do Machine Learning research

So Malik has to install Python, TensorFlow and all the dependencies 🙂

We had a students of Business and Management, Telkom University visiting our class and did some interviews, including to the CFO, Capt. Syahna 😀

Can’t wait until the next Saturday 🙂 See you kids very soon 😉

ProCodeCG Kids Regular Coding Class – ESPectro Programming & Open Topics – 6 Jan 2018

Hello Saturday class 🙂

We had a newcomer: Firaas 🙂

There was a problem with Firaas’ laptop: it wouldn’t let browser to browse 😀 Capt. Azriel (green shirt) tried to help

Capt. Faris (dark grey ProCodeCG jacket) and Capt. Ain (grey shirt) helped too

It took 3 captains and we still couldn’t figure it out 😀

So we took different laptop and let Firaas started learning basic programming with Minecraft Hour of Code peacefully 🙂

Yep, it’s done! 🙂

and then Blockly Games

Next, CodeCombat 🙂

Capt. Ain helped

Firaas learned for 3 straight hours 🙂

So he deserved some Minecraft time 5-10 mins before the class ended 🙂

Ain learned a new thing: BlocklyCraft 🙂 A drag-and-drop Minecraft Modding programming 🙂

Capt. Faris gave Ain a jump start 🙂

Ain will be given the task to explore BlocklyCraft 🙂

Nafis was assigned to debug his project all over again 😀

start from scratch

ready to test

the LCD didn’t work

but the ultrasonic sensor worked

trying to make LCD works

it did, and counting 🙂

then we added buzzer, and it worked 🙂 we still hadn’t time to figure out how to make it beep when it counts 🙂

Cinta was doing another challenge in Python

Creating a Hangman game 🙂

These girls collaborating to create the questions 😀

The result

And for the next session, Cinta wanted to do some Minecraft Modding 🙂

While Azriel had a bad headache LOL

We were trying to figure out this code to create a triangle in Minecraft using BlocklyCraft

We had tried every possible ways

And yet it still didn’t work

And kept giving us false result :((

So we called Faris for help

And he found out that something was wrong with the converter and it kept crashing the server

Apparently the converter from Blockly to JavaScript didn’t work smoothly.

So we assigned another task to Azriel: creating structures with RedStone

And our research, conducted by Capt. Faris had shown lots of progress

now the algorithm can count objects

So we add another data sets

we used bigger data set for higher precision

comparison of left: larger dataset, right: smaller dataset

the counting

the dataset

how to change dataset

we need place to run the training because the last time we tried, Google Cloud Engine didn’t work 😦

Will be reporting again next week 🙂

ProCodeCG Kids Regular Coding Class – Open Topics – 16 Dec 2017

Our open topics class 🙂 Let’s see how many topics do we have today 😉

Capt. Faris, ready to continue our research about TensorFlow etc. 🙂

We’re researching how to recognize certain object in real time with a camera 🙂

Yep it works 😉

It certainly recognizes persons

and cellphone

Nice! Now we are going to add more objects and train it to be able to recognize the new objects 🙂

Ain was busy working on his assignments (while also preparing for kids coding camp because he’s going to be captain on duty ;))

Ain had successfully created a simulation of wheels going up and down slopes 🙂

And a simulation of some round objects falling into some surface

We’re trying to simulate molecule behavior 🙂

Captains bonding before the class 😀

Capt. Cinta was so busy catching up with Python programming

She go through all the examples in the handout and ready to be given a new project  🙂

Emma is back 🙂 She is the only one in the class learning C/C++ for AI programming 🙂 She was also given a task to explore Python AI Library as a comparison and just in case we need her to help us with the TensorFlow project 🙂

While J still stuck in finding ways to create a running text in Minecraft

So he created something else instead 🙂

J was still figuring out how to solve the problem with piston limit 🙂

While Azriel started to learn RedStone

Azriel created automatic door with pressure plate and with lever 🙂 There’s so much things to explore with this new skill 🙂

And now we have two web programmers: Nadine

and Nanin 🙂

They both started to learn HTML and create  their own website design 🙂

They look so happy 🙂

These girls type their own code and make some changes to the color, background, size and fonts 🙂

And they help each other, of course 🙂

Vian 🙂 Got some help from Ain to make what’s in his head reality 🙂

Vian always has interesting ideas, and Ain always knows how to implement it 🙂

so they make a great team 🙂

The result 🙂

Tyo did lots of research about how to connect Java to Microsoft Excel 🙂

Tyo was still working on the project to generate invoice from from Java 🙂 Awesome work and endurance Tyo 🙂

Another activities in the class:

Capt. Fizhan trying to fix Nanin’s won’t-connect-to-internet laptop 🙂

And these two little bros of Ain were playing with Ain’s work 😀

Lots of topics and progress as always! 🙂 Can’t wait until the next class 😉

ProCodeCG Kids Regular Coding Class – Open Topics – 9 Sept 2017

Hello!

This Saturday we had two newcomers 🙂 This one is Al 🙂

Al learned intro to programming with Minecraft Hour of Code 🙂

After he finished task one, Al continued to learn about procedures with LightBot 😉

Then he continued with Blockly Games 🙂 Lots of work today Al, well done 🙂

The second newcomer is Adit 🙂

Adit learned the same things Al did 🙂

Adit was tutored by Capt. Faris 🙂

Finished the first task

and then move on to the next 🙂 Adit seemed so excited 🙂

Emma was still working TicTacToe strategy

The code generated some errors after Emma added a new function

Well, with a code looking like this, we certainly need time to find out the problem 🙂

Aidia started to create games 🙂 With the guide of Capt. Faris 🙂

Aidia already had ideas in mind about the game she was going to create 🙂

Aidia was so excited to create her own sprites 🙂

Finally, Aidia’s first game 🙂

She just couldn’t stop 😉

Ain! He came with lots and LOTS of progress 🙂

From all the tasks and challenges, he created this “Kresek Terbang” game 🙂

The game is so neatly created and detail, using brilliant tricks and techniques

Like usual, Ain never do anything less than excellent 🙂 Look at how many sprites and object he created 😀

Ain also uses a very smart way to put objects in random while the screen moving to the left

Ain gave lots of tricks and idea to Vian 🙂

Vian was going to make what’s in his head happen 🙂

Vian learned lots of new tricks to make his ideas happen 🙂 Well done Vian 🙂

Vian also wanted to create his own logo 😀

So we let him express his creativity for a whiel 😀

Ajil’s game now working just fine 🙂 Last week we had the GameMaker kept hiccuping 😀

Ajil tested all the game he had created

Making sure all is running smoothly 🙂 Next week Ajil will be ready to learn something new 🙂

Tyo had a new idea for a new project 🙂

He wanted to create a temperature converter 🙂

Tyo is a very determined boy. He insisted to write his own code, line per line. He refused to copy paste examples from the internet 🙂  Tyo has a problem with casting this variable to integer

Capt. Faris helped him out 🙂

So this is going to be Tyo’s homework and we’ll see the progress next week 🙂

Look at what Capt. Faris learned in the class while teaching 🙂

Capt. Faris showed Capt. BR his ProCodeCG Attendance App with Face Recognition 😉

Faris took my pics last week and let the code learn, and now it recognize my face 🙂

Not yet recognize Capt. BR

Because the system has only learned Faris’ and my face, Capt. BR was identified as Faris 😀 Later Faris took pics of Capt. BR, feed it to the system, and it can recognize Capt. BR too 🙂 Awesome!

Well, when Faris’ laptop goes like this, that means the class is over 🙂

See you next week! 🙂

 

ProCodeCG Kids Regular Coding Kids – Open Topics – 2 Sep 2017

ProCodeCG Open Topics Kids Coding Class 🙂

These girls, Echa and Aidia arrived early 🙂

They’re ready to learn more about programming with Minecraft 🙂

Echa and Aidia started to learn Minecraft Designer before they start coding with JavaScript on Spigot Server 🙂

Neila joined the group of Minecraft Modding with Echa and Aidia 🙂

They logged in to the same Spigot Server so they can play and code together 🙂

Capt. Faris (grey jacket) helped the girls with starting up the server and logging in to it 🙂

Ain! So excited to see the progress 🙂

Ain has created an amazing game with nine levels 🙂

The game is very well and carefully designed 🙂

Each levels offers different challenges *that escalates in an unpredictable way 😀

Ain has also created another game, a very detailed game with animations

He creates LOTS of sprites

and each sprite has LOTS of images for animations

This one is totally a detailed and determined kid 🙂

The game is about a watering can that can walk (while animating)

and when it approaches the plant and water it, the plant will grow 🙂

the code of how the plant changing sprite to give growing animation 🙂

And after demoing those two awesome games, Ain created another one

He hasn’t explained how this game work

because after Vian arrived, Ain was told to give ideas to Vian 😉

so they teamed up to create games together 🙂

Emma was still working on the Tic-Tac-Toe project

She was in the process of creating data structure and algorithm to make computer chooses the best possible move

She developed some functions and started to list move possibilities

the SPOTS variable shows the possible positions to move. The algorithm still choose the move closer to the upper left cell. Will be improved after the weighting process has been figured out.

Capt. Faris on duty 🙂

Very busy doing his research on ProCodeCG Attendance List with Face Recognition 🙂

Faris was doing some training to his code

So it will recognize his face and tell the system that he has logged in 🙂

The result of the matching process

And then he started to train the code with different datasets so it will recognize different person 😉

There are always so much things going on, and there will be more next week! 😉

 

ProCodeCG Kids Regular Coding Class – Open Topics – 22 July 2017

Whoaaa, got lots of things going on in our open topics class yesterday 🙂

Nico was learning GameMaker and tutored by Capt. Azriel and Capt. Faris 🙂 He created Flappy Bird dan Break Out Game 🙂

Dika created a Tilting Game for Android 🙂

There was some errors and Dika was hungry so he decided to eat first 🙂

Capt. Faris, while on duty he also did some research and exploration like usual 🙂

Faris likes challenges 🙂

 

He does CodeFights very often 🙂

Cinta still exploring about what to present on exhibition: hardware or software 🙂

Capt. Malik started to explore C 🙂

We’re planning to teach kids Artificial Intelligence in C 🙂 This is going to be useful for Malik’s ongoing projects 🙂

Malik installed CodeBlocks for C IDE

but it was so laggy we’re going to switch to CodeLite

Capt. Azriel!

Thanks so much for helping 🙂

Rafi examining his ESPectro while waiting for his Minecraft Server loading and connecting

There was a problem with Rafi’s Spigot Server. It wouldn’t connect to localhost. Will find out 🙂

Vian 🙂 He was in the mood of creating games 🙂

Vian created a totally new games with animation 😉 Capt. Cinta helped too 🙂

Koosha demonstrated how to do things we did with Scriptcraft with command block 🙂

Jundy had many ideas and things to do 🙂

but J was given a task to port what he created in Scriptcraft to command blocks

and so did Gyan 🙂

Tyo knows exactly what he’s going to present on Exhibition and he’s working seriously on it 😉

Capt. Faris helped us with some important syntaxes

And now it worked fine 🙂 Now it’s only finishing 🙂

Emma is a very focus programming. She just won’t stop 🙂

We’re opening a new topic: C programming for AI, for her 🙂

She’s also the only one in class using Linux 😉 So cool 🙂 Emma was given things to do at home because she had finished the handout 🙂

The class 🙂

So many interesting things and awesome progress like always, and next week there will be more! 🙂

This is Ruben 🙂 He had just started ESPectro Programming, and decided to use 2 sessions doing this 🙂

Another newcomer is Abdillah 🙂 Abdillah is experienced with robots and have won several competition 🙂 We give him a project to create counter with ultrasonic sensor 🙂

Aaaaanddd there was a big surprise: our little captain is back 🙂 Hello Awa 🙂

He was a little bit shy with his close-cropped haircut 😀

Awa with the Sr. 🙂

Awa Sr. helped Ruben with ESPectro libraries 🙂 Thanks sir! 🙂

Awa tested an ultrasonic sensor with ESPectro

And it worked with the help of Abdillah who finally figured out to find the correct pin out 🙂

We also had Clarence 🙂

With his awesome ideas 🙂

Clarence created a flight shooting simulation and he enhances it using AI

The class 🙂

Some kids didn’t come up for some reasons but more will show up next week 🙂
