As we all know, ChatGPT is the brand name of the AI service offered by OpenAI. Similarly, Bard is the brand name of a similar AI service offered by Google (In this article, we focus on ChatGPT).

ChatGPT is a generative AI model, which can generate human-like responses when prompted with text-based inputs.

So, what is generative AI and what can it do?

Versatile Capabilities of Generative AI

With a given prompt, generative AI can perform tasks such as code generation, document summarization, information extraction, marketing campaign creation, and even serve as a virtual assistant or chatbot.

But how can it generate content?

Well, it trains its AI model by utilizing components of Artificial Neural Networks (ANNs) with a large amount of existing text, audio, or video-based data as input data.

Limitations of Generative AI (WRT ChatGPT 3.5)

Can it give you an answer by analyzing the data you provide as input?

If the question inputs are simple, it can, but it can’t do it if we need to analyze the situation and predict all possible scenarios. Also, it doesn’t always provide the correct answers.

The Need for Advanced AI

Let’s assume that I have a dataset about an advertising campaign and I did research about my customers who consumed my products in the past, and I have so many data points about those customers, including their demographics, buying patterns, buying behaviors, educational and earning capacities. Based on the data, I am planning to launch a new product, and I need to develop potential product scenarios with AI. I cannot do that with the existing GPT-4.

The Future with AnalyzeGPT

So, can I achieve such a result with these AI technologies? Yes, we can. According to rumors and some AI leaks, the OpenAI team is currently working on a project called AnalyzeGPT/ InstructGPT, and its main goal is to address the mathematical reasoning issue in the current model.

There are research papers and publications on InstructGPT by the OpenAI team, and you can access them via the following link. (Link: InstructGPT)

Insights from a Chat with BingAI

Here are some screenshots of the chat I had with the GPT-4-powered BingAI chat tool (chat date: 2023-07-05), which has revealed more details about the AnalyzeGPT project. At a certain point during our conversation, it asked me not to reveal this secret to the public. ????

According to leaks from Bing Chat, it is scheduled for release in September 2023.
(I waited as promised ????)

Future Speculation

However, with the recent Microsoft event (2023 September 22) and the launch of Microsoft Copilot, the rumors will likely become true in the near future.

Why this Subscription and ANPR based Toll Collection System?

People use highways mainly to save time by avoiding traffic jams. When it comes to Sri Lankan expressways, people lose their gained time at the counters due to long queues, especially during peak hours. To overcome this issue, RDA Sri Lanka increased the number of toll plazas, but it did not provide a solution to the issue.

Both E02 and E03 expressways do not operate at their maximum traffic handling potential. Several studies and best practices by other countries suggest several best practices to maximize the traffic flow on existing expressways, such as congestion pricing and real-time travel management.

This study aims to evaluate a system to increase expressway usage while decreasing the queues at the toll plazas.

Traffic jam near Ja-Ela expressway exit toll gate between 7:00 pm - 7:30 pm (Weekday)

Let’s understand some technical terms and how we can apply them to the research.

What is ANPR Technology?: The advancement of computer vision-related artificial neural network (ANN) innovations in image text recognition systems enables Automatic Number Plate Recognition (ANPR) or Automatic License Plate Recognition (ALPR) technology.

Application: ANPR technology uses the scanned image of the number plate and converts it to a text and uses the text as the vehicle identification at the toll gates.

What is the Subscription Business Model?: Instead, of paying for the product or service each time the customer uses it, the subscription business model allows users to register and use the product or the service at regular intervals.

Application: Instead of regular payment collections, people have an option to subscribe to a particular expressway and travel without waiting in queues at toll gates.

What is MLFF?: The multi-lane free-flow (MLFF) is a system that allows free-flow high-speed tolling for all highway users.

The Proposed Expressway Toll Collection Mechanism.

A subscription-based tolling system should implement on top of an advanced technical tolling system.

MLFF is already implemented in many countries successfully. It is also equipped with ANPR technology and congestion pricing-related traffic management. Therefore, the MLFF mechanism can consider a subscription payment system instead of a regular payment system. Therefore, the study is focusing on the user acceptance of an automated, congestion-based, subscription payment collection system.

The proposed system is not suitable for non-regular expressway users. A limited number of MTC gates should operate to provide service for them.

Made in Japan cars are popular all over the world. Based on google search data, here I have analyzed the most popular Japanese car manufacturer and the popularity change over the years (from 2010 to 2020).

Toyota, Honda, Nissan, Suzuki, Mazda, Subaru, Mitsubishi, Daihatsu, and Isuzu are the most famous automobile manufacturers from Japan but in this analysis, I only selected the most famous 6 brands over the 10 years. We all know them even by their logos.

Now let’s see how the popularity of each of these changes based on world search patterns.

As per the data visualization video, Honda is the most popular Japanese car brand in the world. If you look carefully, there’s a popularity peek for Honda between June – September of most years. Also, slightly peek between March-May. You can understand it with the below chart as well.

Why is there a peek between June – September?

After carefully analyzing the search quarries, we found that most of the following events happen between June to September each year from 2010 to 2019.

• People look for next year’s model (upcoming model) details during this period.
• Release/ Introduction of a new car model – Eg. Honda Mobilio introduced in September 2013 and this caused the slight peak
• Announcement of newer models and the motor-shows

In the year 2020, the popularity of each car brand has dropped due to the world covid pandemic and due to lockdowns in most parts of the world.

Which part of the world and in which country do Honda most popular?

It’s not the USA or the American region. It’s Indonesia and the Asian region.

Here we focus on the most popular Japanese car brand, which is Honda brand but the same analysis can be done on all other brands.

With the introduction of the Apple iPhone series, companies identified that so-called smartphones are not really smart anymore. From 2002 to 2012, Nokia was the market leader. Their Symbian OS had its limitations but the company rejected to compete with Apple with similar technology or tie-up with booming android OS.

Below graphical analysis will show how the Mobile phone market share (world) varies from 2010 to 2020 and how Nokia lose the game over Apple and Samsung.

Samsung manufactures a whole range of mobile phones targeting various audiences while Apple is following the broad differentiation strategy.

Apple products are more expensive but there are Samsung products (Samsung Galaxy S series and Note series) developed to compete with the high-end customers while Samsung has introduced a low cost and medium cost mobile phone series for all types of buyers. (Samsung A series, M series, J series and etc.)

If we select the same data and filter it with a rich country and a medium-income country, the target audience gap can be easily seen.

Below visualization displays the mobile phone market share change from 2010 to 2020 in Australia.

Australians have more disposable income, therefore they are using Apple products.

The below visualization displays the mobile phone market share change from 2010 to 2020 in Sri Lanka.

In a Market like Sri Lanka, the Samsung is the market leader while Apple phones are having below 10% of market share.

One important fact can be noticed from all three visualizations. The Chinese budget mobile phone manufacturer, Xiaomi is boosting its market share with a shorter period of time in all three visualizations.

Innovation is the key and the customers can expect the unexpected with the current rivalry among the above four brands and also other upcoming brands.

What is Time Travelling or Travel Through Time? 

Well, Simply it can define as a Slow Ageing.

Let’s assume that you have a twin brother and you born in 1990. Now you and your twin brother, both are 27 (as at 2017) and just assume that you can slow the time on your clock (frame) by half relative to your brother. After two (2) years, you synchronize your clock or frame with your brother’s. Therefore when your brother gets 31, you still not reaching to 31, you are 29. Then, it means you have travel through the Time. You went to 2021 but you are still 29 and your twin brother is 31. This means you have traveled to the FUTURE. Yes, now you can say that “there is a time for me which I can control”

WAIT!!!!! Is there Really a Time for Me?

Yes, what I have mentioned above has scientifically proven by the great scientist, Sir. Albert Einstein with his Special Relativity Theory. According to his theory, maximum speed a particle can ever achieve is, c = 3×10⁸ m/s (approx.) and when a particle getting closer to the “c” relative to earth, time on particle will slow relative to the time on earth. Bellow mentioned, time dilation Lorentz equation can use to show above assumption. 

According to the equation, if you can travel at the speed of V = 2.5981×10⁸ m/s for two years, (you left on your 27th birthday) when you come back, you will be younger than your twin brother. You can join your twin brother’s 31^st  birthday party and you can celebrate your 29th birthday with him. 

That’s the way to have a time for me.  

This theory is a complex and by searching for Lorentz Transformation learning material, you will get more new knowledge. If you want to learn more about Einstein’s Relativity, bellow video will help you to understand the basics.  

The movie, Interstellar directed by Christoper Nolan used above phenomenon in his movie.

Hi Guys and Gals, Maths Guy is back as promised to teach you the Mind Reading Game.

Please read MathsGuy.Com/Mind-Reading-Game  blog post before continue reading this blog post, otherwise you will be clueless…..  

Still can’t you figure out the trick? Then, let’s learn the trick behind the mind reading game and feel the beauty of Mathematics. Hope you can remember the steps and answers

Well what is the animal you thought? 

Is it Elephant?

Oh yeh!!!!!!

OK, Here is the Magic behind the mind reading game

I’m not gonna analyze all the steps because all of you guys are smart enough to understand it by reading following basics of Maths.

Ok tell me, what’s the answer of 9×9, it’s 81 right? Then what about 7×9, 15×9, 785×9?

Now what are the answers?

7×9 = 63

15 x 9 = 135

785 x 9 = 7065

Now, we shall move on to the next step of the trick. (Next step is If you get more than one digit answer, then again repeat the above step until you get a single digit answer.)

ok, what is the sum of the digits? 

8+1 = 9

6+3 = 9

1+3+5 = 9

7+0+6+5=18; again, 1+8 = 9

Got it?????

Theory : If you multiply any number from 9 and add up the digits until you get one digit answer, you  will always get 9 as your answer. So, at the end I know that the number you have in your mind is 5. (9-4 = 5) Then before the trick, I carefully selected a famous animal who live on the land and I forced you to think about the ELEPHANT.

I have created a simple maths game, computer program (Desktop Version, Windows Only) and by using below link, download it and trick your friends easily. (totally different from above game)

 Hi guys & gals, this is my first blog post on MathsGuy.Com

Ok then, let’s play the mind reading game.  (You may follow the steps or you can watch bellow video)

• Think of any number. Yes any number! (Eg: 8)
• Then, multiply it by 3 (Eg: 8×3)
• Ok, then add 1 (One) to the total you get.
• Then again multiply your answer by 3 
• Then subtract 3 from your answer. Ok?
• Fine, then add the numbers of your answer. (Eg: If your answer is 52, then 5+2 = 7)
• If you get more than one digit answer, then again repeat the above step until you get a single digit answer. (Eg: If your answer was 438, then 4+3+8=15, then 1+5=6)
• OK now you have a single digit number in your mind. Now, subtract 4 from the number you get.
• Now assign relevant English letter of your number. (Eg: 1=A, 2=B, 3=C etc.)
• Now you have a letter in your mind, Yes? 
• Now think of an animal name starting from your letter who lives in land.
• OK? 

Then what is the last letter of the animal you thought? Wait, don’t spell!!!!! I’m gonna read your mind  

Is it ” T “

I have developed a simple python based code so you can use it as a guideline. Please refer bellow simple steps to proceed with the game.

As I promised you earlier, here is the video with easy guidelines.
