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

Standard

We finished the #3 and #4 session today 😉

IMG_9638

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

IMG_9639

IMG_9640

IMG_9645

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

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

Today we will test object detection with darknet and darkflow configuration

photo6150062494501152961

It of course took a lot of effort and resources (in terms of time and computational resources :D)

photo6150062494501152962

Every participants are free to decide darkflow or darknet. But both implementations are expected.

ProCodeCG Kids Regular Coding Class – 6 April 2019

Standard

Saturday’s Coding Squad 🙂

IMG_9014

Capt. Faris is given a project to detect hoax and real news

IMG_8976

plus investigating the neural nets architecture being used by our machine learning platform

IMG_9039

The codes

IMG_9040 IMG_9052

Hafiz’s Plant vs Zombie Game is getting better and better 😉

IMG_8977 IMG_8981

we need to add lots codes to add more features to the game

IMG_8990 IMG_8991

IMG_8993 IMG_8994

Now the game has the randomly generated points (the yellow dots)

IMG_8998 IMG_8999

it also now has flowers that can shoot peas 🙂

IMG_9033

Hafiz has to repeat the process for lots of sprites

IMG_9035

and then define scoring and rules of the game. Lots of hard work but fun 🙂

IMG_9053

Sulaiman is going to choose his own project today 🙂

IMG_8978

We borrowed Aidia’s book to find a suitable project for Sul 🙂

IMG_9004 IMG_9003

IMG_9006 IMG_9010

IMG_9012

After a while, Sul finally chose this one 🙂

IMG_9013

The result 🙂

IMG_9026

and then Sul started to create running text structure like Capt. Awa was doing earlier

IMG_9055

Syadad started creating games today 🙂

IMG_8979

The first sprite

IMG_8986 IMG_8987

Object movement test

IMG_8989

The other sprite to be eaten by the first sprite

IMG_9005

room setup

IMG_9017

Yayyy, Syadad’s first game 🙂

IMG_9037

more object arrangements and background

IMG_9042

We will add scoring in the next class 😉

IMG_9050

Aidia is improving her sophisticated locker system design 😉

IMG_8980 IMG_8984

Aidia added more structures to her world

IMG_8985 IMG_8988

She brought some books for references

IMG_9009

So whatever Aidia created in her world is pure her creativity; she combined lots of ideas into unique structures

IMG_9028

IMG_9034

Capt. Awa asked for a challenge and so the challenge was creating a running text structure

IMG_8983

No one has ever created this before because of it’s tricky nature. By using piston the furthest shift is 7 blocks

IMG_8995

But Awa wouldn’t be a Captain if he wasn’t qualified 🙂 He brilliantly overcome the limitation by making it circular 🙂

IMG_9020

The structure. Unbelievable. Impressive. Outstanding. 🙂

IMG_9022

Awa tried several structures before finally found the correct one

IMG_9023

Minecraft can be used to learn many things including logic, problem solving, creativity, including mechanical structures and electronics logics 😉

IMG_9025

Experimenting with the machine

IMG_9032

adding shield to make it waterproof 😀

IMG_9054

Andra is still going through the intro to coding 🙂

IMG_9008

Today he learned about function through pattern

IMG_9018

IMG_9019 IMG_9029

And then moved on to more challenges. Next week Andra will learn visual coding with actual coding scripts 🙂

Standard

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

IMG_8664 IMG_8665

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

photo6127299760537840124

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

photo6129897330988656723

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

photo6129897330988656722

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

IMG_8118

Aidia created some rollercoasters and our plan is to add counter to count how many cycles a cart has gone through

IMG_8123

Sam is still working on adding more features and improving the UI/UX of his Juz’amma App 🙂

IMG_8069

IMG_8082

We’re finding ways to give user the info about how many verses have been memorized

IMG_8088

There are some alternatives: with progress bar, with checklist, or numbers

IMG_8089

For now each verse has a check list, the next is how to show the summary 😉

IMG_8129

Badi has made excellent progress!

IMG_8070

The website is done!

IMG_8074

With the booking calendar!

IMG_8075

whoaaa this is incredible 🙂

IMG_8079 IMG_8073

Fadhlan is making his way to make the micro servo securely planted on the platform

IMG_8084 IMG_8091

Fadhlan is enjoying things like this

IMG_8096

Thing most kids are avoiding 😀

IMG_8098

Nice installation

IMG_8104

Undergone navigating and mapping test

IMG_8117

the readings 🙂 The remaining problem is the wheels wouldn’t move. Will check on that next week

IMG_8120

Capt. Faris explored deeper about faking image, videos and voice

IMG_8080

He is really doing a serious research

IMG_8107

He even investigated how to do deep learning from a 6 months chatting history

IMG_8125

Abil started to create his shooting game today

IMG_8081

The assets are finished but not yet the code 😉

IMG_8085

IMG_8110

Syadad had finished lots of Minecraft Hour of Code Series and LightBots at home

IMG_8108

Today he started a Blockly Games journey 😉

IMG_8112 IMG_8114

After Syadad is done with Blockly and CodeCombat then we will start creating games 😉

IMG_8122

IMG_8127

Every kid has their own pace and interests, that’s why they have to be treated personally and differently the bring out their best 😉
