AI

### About

AI, short for Artifical Intelligence, is a term first coined by renowned AI pioneer, software engineer and author John McCarthy in 1956. It describes an intelligence which is neither human nor animal, but man-made. For decades after, AI dominated the realm of science fiction, such as in the novels of Isaac Asimov or the Terminator movies, before slowly becoming reality in the 2000s.

### Development of AI

As with many groundbreaking technologies, AI was brought about by military requirements to quickly and precisely analyze enemy movements, especially the flight paths of incoming missiles. The AEGIS system, employed on many NATO warships, is an example of a crude but effective AI that adapts to threats that are facing the ship and "learns" the probable flightpaths of incoming missiles, but as a technology developed in the early 2000s, it is limited in its capabilities.

In the 2010s, Text Transformers, Voice cloning and Image generation AIs slowly became available to the public. These were largely used for entertainment purposes, generating largely nonsensical but amusing stories or responses similar to what a human might say if they were heavily intoxicated. Cleverbot was one of the first transformer AIs to become well regarded, while projects such as Microsoft Tay were quickly taken down by their developers as they began to respond to users with racist and illegal responses, such as denying the holocaust. This would be a repeating pattern for many early "chatbots", transformer AIs that people could chat with for entertainment.

In the 2020s, the technology eventually became refined enough to be useful, with Image Generation AIs becoming good enough to fool art critics into believing their works were man-made and sparking widespread controversy, especially as Deepfakes of voices from important people such as Presidents and Ministers were used to create difficult diplomatic situations. But it was OpenAI's ChatGPT that took the world by storm, as the first Text Transformer that was not only useful and semi-consistant, but able to learn and adapt to roleplay as various characters, create food recipes, write engaging stories and many, many more.

To this day, ChatGPT is the gold standard for AI thanks to its flexibility and adaptability, although many competitors such as Microsoft Azure have begun to try and get a share of the market.

### Neuro-sama's origins

At around this time in circa 2018, a young turtle began to use AI's for projects furthering his programming skills- Videos of his AI's landing rockets from around this time still exist, and in 2019, he created an AI that could play the game Osu!.

Seeking a way to show off his achievements, he started streaming the gameplay on Twitch, which led to him attempting to find a fitting way to engage with viewers... eventually, Airis, the first AI-child of his creation, was born... and soon abandoned in favor of the more refined Neuro-sama who was built on top of her codebase.

### Neuro as an AI

In essence, Neuro is another Text Transformer type AI. She receives chat messages, processes them, and generates a response that most likely matches what they were asking for, based on her pool of knowledge on the subject. The generated text is then fed through a Text to Speech service, generating her voice which is played on stream, synchronized to her Vtuber model's mouth movements.

Since her creation, several elements have been added and improved upon, most notably a long-term memory of events and people that she met, as well as a filter system which prevents Neuro from responding to controversial topics, talk about harming herself, or engage in pornographic roleplay.

When playing a game, a second AI assists her with Computer Vision, allowing her to recognizes shapes and images for processing both by the Gameplay AI and the Text Transformer AI, primarily allowing her to play the game, but occasionally also comment on the gameplay. A similar Computer Vision AI is used when she watches videos or looks at pictures, albeit with a higher resolution and higher fidelity as there is a stark contrast between an Osu circle and, for instance, a fanart of her.

When singing, another seperate AI uses a clone of her voice to sing a song thats loaded into the system- The regular Text to Speech voice is paused during this time.

Her body movements are currently not controlled by AI but are a pre-recorded loop of movements by Anny, although the V2 model can dance in tune with the music when singing. This is also not AI, but data from an audio-visualizer fed into her body movements.

### Hallucinations

AI of all forms are known to spontanously create false information due to the way their memory works. By chopping words and information down to Tokens and then re-arranging these tokens into new information, they often generate data that has nothing to do with the rest of the data or simply makes no sense- Which in Transformer AIs can have wildly different effects, from simply misspelling words by rearranging the letters, to generating what are typically called "Hallucinations".

In Transformers, hallucinations can be (but not limited to):

- Descriptions of events that they state as fact, but that never happened

- People added to stories that don't exist in the context of the story

- Changing the names, genders, races, occupation and background of existing people

- "Forgetting" previous information as it was tokenized down into nonsense, or tokenized as "false"

- Irrational fear of things that dont exist and never happened

- An incoherent mess of letters and words that, when spoken, create an eldritch screech of pure horror.

Neuro has been known to exhibit all of these on a frequent basis, creating large parts of her lore by stating complete fiction as fact.
