How to debug a neural network that is not working?
We have so many choices of neural network architectures now and days that it can be difficult for beginners to decided on which one to use for a given problem. And even when you have the right architectures, sometimes your network just wont learn a thing. So like in any coding, their are unit tests you can try to debug your network. Here are a few ones:
1) Pass a single data through your network and look at the output. Is it the right size ? If not, check your model and make sure you output the right thing.
2) Train your neural network with one single data. Is it able to output the perfect target after a of couple thousand epoch (you have only one data so you will need more epoch then usual) ? If not, you may have a bug your network because a sufficient large network should at least be able to learn by heart that one sample.
3) Now that you've got 1 and 2 working. Train your network with your dataset that you split into two categories: Training and Validation. Your validation will be use at each X epoch to see how the network it behaving with new data. In this phase, you will want to see if your network is able to over fit on your data. If it can't, it probably means that you may not have the right architectures for your problem and dataset.
Do you have other ways to test your uncooperative network ? If so, let us know how you debug it in the comments ! I'm sure everyone reading this would love to know more about this !.
🧁 Big O notation🧁
Anyone can write code, but writing the most optimal one is that what counts. Big O notation is used in Computer Science to describe the performance or complexity of an algorithm. Here we have two main aspects Time and Space complexity, our goal is to be as close to O(1) and as far from O(n!) as possible.
Alternative Big O notations(fun) version:
O(1) = O(yeah)
O(log n) = O(nice)
O(nlogn) = O(k-ish)
O(n) = O(ok)
O(n²) = O(my)
O(2ⁿ) = O(no)
O(n^n) = O(fuck)
O(n!) = O(mg!)

I’m sure this type of question has been asked to every programmer at least once or twice. 🤦🏼♀️I don’t think we should be upset with these questions. If people can’t figure out what you do with computers, and you’re doing reasonably well money-wise, they end up thinking you’re something like a wizard. 💁🏼♀️Their resulting misconceptions can go from funny, to cute, to horribly wrong.🙅🏼♀️ ⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️⁉️DO you have any funny stories write me down in the comments⬇️⬇️⬇️

How to level up your discipline to not only become a better programmer, but to become a better anything 👨💻⠀
Self-discipline is very much like a muscle that needs to be exercised. Being able to put off instant gratification for longer-term success is a very valuable skill that has a resounding impact on your life ⚒️⠀
Here are my 3 tips to help you build your discipline muscles:⠀
✅ Prioritize getting into and staying in 'The Zone' ⠀
Chunk a period of time to be 100% distraction free in order to work. Start small and give it your all. If you can do more than the time you allotted, do more. The issue for most people is just finding the motivation to start. You'll find that once you get started on your work, the motivation and flow state comes on its own.⠀
✅ Develop a “Growth Mindset”⠀
In a growth mindset, people understand that their talents and abilities can be developed through effort, good teaching and persistence. They believe everyone can get smarter if they work at it regardless of how long it takes.⠀
✅ Get your sleep⠀
Poor sleep can contribute to a variety of physiological and psychological complications, including high blood pressure, diabetes, weight gain, heart disease, paranoia, mood swings, depression, and anxiety. Inadequate sleep is also a productivity and discipline killer.⠀
What are some of your tips to improve discipline? What was difficult for you to improve in? Lmk down below, have a wonderful week 🥃⠀

Today, I attended an all day company culture / introduction session. (I tried hiding behind my 3 monitors but they eventually found me 😅)
To be fair, it was interesting learning about different part of the organisation that I didn’t know existed (yes, there is a world beyond software development 😂).
We did lots of group activities throughout the day. The one activity that marked me though, was the ice breaker about sharing an embarrassing story with the group... You wouldn’t imagine some of the stories.. Let’s say that I’m glad I’m a Software Engineer 😄
Now it’s your turn, tell me an embarrassing story that happened to you ❗️
Exercising is one of the best thing we developers can do for ourselves.
Sitting for hours behind a computer is really bad for your body but specially for your back.
Since I started to program in 2018, my back and my condition has got worse. So I decided to go to sport this year.
To be honest, I didn’t know exactly what to do, because I don’t like to go to the gym and because in the past I’ve done soccer and kickboxing, I decided to go do kickboxing again.
The results are already kind of impressive. I don’t die when I go upstairs, I am happier, I have more energie, I am not tired the whole day and I haven’t less back pain (I still have to buy that chair 😬). Sporting has also positive impacts at your brain while learning and at your mental health.
Do you have practice some sport? If so, what? If not, would you like to?
It’s International Day of Women and Girls in STEM and I am so proud to be part of this #womeninstem community. •
Being first generation came with a lot of challenges that may have been alleviated by access to knowledge. This was specially true when I was considering getting a PhD. So in the spirit of celebrating women and girls in STEM, let’s talk pros and cons of getting a PhD.
- Flexible time schedule
- Tuition is paid and you get a stipend - You get a Masters degree along the way - Pursuit of intellectually stimulating work - You become an expert in your field - Freedom to pick your project - Travel for conferences and collaborations
- Lack of gender, ethnic and racial diversity - No set schedule, so a tendency to overwork and burn out
- Social isolation - Stipend is very low (15-30k / year)
- PhDs take > 5 years to complete
- After Masters is done, requirements to get the PhD can be vague
- May make you overqualified for the job you want •
These are specific to my experience so please share your own, friends!

Получилось ли у тебя нарисовать свои собственные графические спрайты ❔
#codewithNab [3/30]. Learned another topic and surprisingly I didn't knew there is something like Truthy & Falsy Operators. Using it in if/else statement makes things much more simpler and easier. Once I finished this topic then there was another easy coding challenge which was quiet easy to complete.
Now my next topic will be related to function and I'll be covered that and rest of this section tomorrow.
I'm planning to finish this section i.e Basics of JS Language tomorrow and start then next section which is much more interesting then this one.
Good night 🌙

Version 2 of the website is live❗️
The past iteration was just about getting something live as quickly as possible. This update, on the other hand, is focused on design and user experience updates.
The biggest change you’ll notice is the product card. I wanted to provide as much detail as possible without adding clutter, which is tough enough considering a card can get crowded rather quickly but 99% of traffic is also mobile so that adds more space constraint. After some testing I decided that displaying the item name and adding a button showing the user where they are about to be routed would provide the most benefit to the user while maintaining a clean design.
But user experience enhancements aren’t always entirely visual. I was also able to optimize the product images and reduce their size by an average of 30% while maintaining quality. This should help improve load times significantly!
Overall really happy with the progress! Check out the site if you want and let me know what you think!

🇷🇺 ru 👇 Do you know the history of computers? Maybe you worked at an 8-bit computer. Do you interest in old computers now?
It seems that there are a lot of old pc lovers, thus at the end of 2019, we have a release of legendary Commodore 64. This version has a full-size keyboard. This model looks like the old original, but it has HDMI and USB. You can buy TheC64(that's the name) for about 200 USD. You can learn some history in the Warsaw Museum of old computers. If you can't visit it in Warsaw I am making a video on my youtube channel.
А знаете ли вы историю компьютеров? Может быть сами когда-то работали за 8-битным компютером. Интересуетесь ли сейчас старыми компьютерами?
Похоже что таких любителей много, раз в конце 2019го вышла очередная версия легендарного Commodore 64. Эта версия включает полноразмерную работающую клавиатуру. Аппарат в целом выглядит как старый оригинал, но теперь есть HDMI выход, возможность загружать программы и игры с современных носителей. TheC64 можно купить за 200 с чем-то долларов.
В Варшаве можно познакомиться с историей в музее старых компьютеров, а у кого нет такой возможности , то вас для готовлю интересный обзор.

I used to think that technology was brilliant. That computers functioned much better than humans can and if there was a technical issue, it was my fault (the user) for not being smart enough to use the technology....
Now I get nervous when I realize people like ME are building all the technology out there.. that hundreds of thousands of people are trusting me, little ol' JoCee Porter, to build a system to do crazy calculations, keep their private information secure, and be able to handle every edge case....
This sometimes makes me so nervous, because as @pilot_pete has made clear, we are all only human and with the best of intentions, we make mistakes, forget semicolons, bring back old code with a rose, just to comment it out again.
I especially get nervous when I think about how hardware sucks with floating point arithmetic... Like there is not really a way to represent small exact decimals on a computer just a close enough approximation to a number (it is all 0s and 1s after all, try representing 1/3 with that), and that systems like airplanes are using these mostly correct, but still off numbers for computing... That it only takes a single carry bit to be off to cause issues (looking at you Boeing)..
But in reality, humans are pretty good at what they do. If you engineer things right with tests, server side and client side validation, following industry standards and best security practices, although there will ALWAYS be bugs, there will only be a 1 in 11 million chance your airplane will crash! .
TL;DR computers are stupid, humans are pretty smart.
🚀Day  of #100daysofcode
One month of non stop codding! Quiet great experience i can say, and i am not planning to stop. Moving on to next 30 days...
👨💻Today i was working updating recipe servings, so if you want to increase or decrease serving for certain number of people, all the ingredients and time are getting updated.
After that i was making model, view and controller for list of ingredients that goes on right site of the user interface. So you can add or delete some of ingredients.
Tomorrow moving on to building model, view and controller for likes (adding recipes to favorite list). ➖➖➖
What are your plans for tomorrow? 🤔

A: When inplace=True is passed, python performs the operation in place (it returns nothing)
>>> df.some_operation( inplace=True);
When inplace=False is passed (this is the default value), python performs the operation and returns a copy of the object
>>> new_df = df.some_operation( inplace=False);

💻 [01 / 100 ] #100daysofcode
🙏 Today I've kicked off my second 100daysofcode and I'm really excited. The requirement for a completed is day is to code at least 2 hours. I'm not limited to a specific technology but I'll mostly wrap my head around reactjs and the likes. The goal for this challenge is to recap my daily improvements, inspire you and build up my portfolio.
✔ On day 1 I started to create my decision web app which I wrote in vanilla js half a year ago. Now I'll rebuild it with react, add more features to it, implement firebase and finally deploy it to the real world. I've set up the environments and have installed all necessary npm packages. Now it's time to start with the UI and create the components. Let's see where it will take me!
My girlfriend also got a new camera. So be prepared for higher quality images😂
Have a great time coding your dreams💪

This month I've taken on some new habits to keep me sane 🧠and engaged - one of them is #gratitudeattitude!
There's an abundance of studies 📚that rave about the mental health benefits of gratitude practice. Writing it down, such as keeping a gratitude journal, is even better because it uses a different part of your brain and makes it "stick" better. The basic concept is that if you pump yourself with positive thoughts and create these neural pathways, over time you'll have so many "positive snippets" in your brain from this exercise that it will change the way you think and you'll more easily be able to see the positivity in life because you've formed these connections deep in your brain.
Keeping a journal 📔can be a bit time consuming, especially if you're a mom like me, a #bosslady or just a general every day #hussler, so I thought I'd share how I've been practicing #gratitude: ✨Become aware of whenever you're feeling stressed, or have a free moment in your day (lunch, driving into work, walking to the bus stop, etc.) and trigger your gratitude thinking ✨Take 30 seconds to just list out 5 things you are grateful for in that moment - you can do more if you want! For example:
💚 "I am grateful for the sun because it feels good on my skin and is making me feel warm"
💚 "I am grateful for having a car that is reliable so I can go to my job that brings me joy"
💚 "I am grateful for my son that fills my day with smiles and gives me sloppy kisses" ✨That's it! Try doing this several times a day, especially when you're finding yourself stressed, or angry or just down.
I'm grateful for having a flexible job that allows me to travel with the people I love and do what I love at the same time! What are you grateful for today?
