Exploring The Possibility Of Artificial Intelligence: Understanding The Ins And Outs Of How Our Brains Work
Are you curious to see what makes up the human mind, and how you can create one yourself? All of these questions are explored in the sections of the Mind Book.
You’ll learn about the processes your brain goes through to take in and process information.
You will soon find out that there’s no need to think a computer cannot accomplish the same level of mental feats as humans do – at least in theory.
You’ll discover why something as simple as a scent can trigger a plethora of memories; how handling your toothbrush correlates to how your mind retains data; and when having Artificial Intelligence (AI) become as normal as using a washing machine will be commonplace.
This book offers data on exactly what makes us think, remember, and solve problems – making it easier for you to replicate these features on computers and other machines!
Our Brain Does A Remarkable Job Of Retrieving Information From Memory Using Patterns
The human brain is a fascinating organ, and one of its most intriguing abilities is the way it stores information in a strictly ordered fashion.
We can see this in action as we attempt to access memories from our past.
For example, when we take a walk down a sidewalk, we might find it difficult to remember the distinct details about people who passed us by.
However, if we encounter even just one small piece of those memories – like the scent of Grandma’s cookies baking – those stored away details come flooding back into our conscious mind.
What’s more remarkable is that there are numerous memory techniques based on this pattern principle: if you can pinpoint one portion of a chain-reaction sequence of events or interactions, the rest will become easier to recall.
Police sketch artists use this technique all the time; they show an individual a series of facial features and ask them to identify which ones remind them of an individual they know.
With just one piece of the puzzle (like eyebrows), they’re able to “trigger” their remembrance and put together the face as a whole image again.
In addition, simple thought experiments make it clear that information is stored on strict pathways within our minds.
Try recalling the alphabet backwards: although you can easily sing your ABCs forwards without missing any letters, doing so in reverse is much harder because there isn’t room for error when it comes to starting out of order!
It’s also difficult to play an instrument from something other than the beginning – you have difficulty playing pieces that you have memorized simply because your brain stores information sequentially – starting something in the middle feels strange and unnatural.
Ultimately, understanding how memory works has allowed us to craft clever techniques for unlocking these seemingly forgotten moments with incredible accuracy – all thanks to how your brain historically stores and organizes information according to patterns.
The Unique Power Of The Neocortex: How Pattern Recognition Helps Us Make Sense Of The World Around Us
The neocortex, which forms the outermost layer of the brain and makes up the majority of its mass, is uniquely big in humans and plays a hugely important role in our ability to think and remember.
It’s responsible for object recognition, language comprehension, body control, sorting information hierarchically (meaning organizing data like steps into sequences), and pattern recognition.
To illustrate how it works: when you look at a word, lower level recognizers fire off signals that correspond to the lines and shapes that make up each letter.
Higher-level recognizers then detect these patterns as well as combinations of letters that together create a complete word.
Thanks to all these recognizers, our brain can recognize things even if we only have part of the information or have never seen them before!
Recognizers are constantly firing off signals as our senses take in new stimuli so we can compare it with stored experiences from before.
The neocortex is key to our memory capacity and modern thinking skills – without it, none of these functions would be possible!
The Neocortex: The Master Networker Of The Brain
All the brain’s information-processing activities lead to one place: the neocortex.
This is where we do our thinking, and it’s connected to many parts of the brain, like the thalamus and hippocampus.
The thalamus is located in the midbrain, and is responsible for assessing whether a sensation, like a taste or smell, is pleasant or not before relaying that information to the insula part of the neocortex.
Meanwhile, the hippocampus plays an important role in remembering new events and recognizing faces — any kind of damage to this area of the brain can cause troubling symptoms like trouble learning new things seen in Alzheimer’s disease patients.
The cerebellum works together with the neocortex to complete certain instinctive reactions an individual may have.
The cerebellum once served as a primary control center for movement yet now most of those responsibilities are handled by our much larger neocortex.
The cerebellum still reigns over more refined movements such as dancing or handwriting – though not any less important!
Ultimately, all “roads” travel through the human brain will eventually lead to your neocortex – so don’t be afraid if you experience a bit of mental roadblock along your journey!
The Neuroscience Behind Human Creativity, Emotions And Intelligence
Though it might not seem like it, even seemingly intangible experiences such as creating art and feeling love are being produced by the brain.
Specifically, sensory input from the world is processed in the insula of the neocortex, where spindle cells work to create those complex emotions.
These cells connect distant parts of the neocortex, so they can be hard to control or make sense of when they’re overactive.
This is why people may make decisions that don’t seem logical when feeling strongly negative or positive emotions.
Similar to this concept, creativity also originates directly in the brain’s neocortex.
People with a larger neocortex often have more profound creative capabilities.
The pattern recognizers that make up this part of our brains are what allow us to interpret symbols metaphorically and appreciate poetry and art.
As these recognizers fire 100 times per second, we can see how this type of creative thinking could become used more quickly and efficiently with practice.
Ultimately, our understanding of modern neuroscience provides clarity on how each individual’s mind works and what it consists of.
Knowledge like this has huge potential for helping us understand artificial intelligence development more deeply going forward.
Hierarchical Hidden Markov Model Allows Software To Learn And Emulate Human Brain’S Pattern Recognition
It’s clear that current technology is already well on its way to creating artificial intelligence.
Through research dating back to the very beginnings of computing in the 1930s and 1940s, scientists have been able to make great leaps forward with AI technology.
One such advancement is achieved through the hierarchical hidden Markov model (HHMM), a mathematical solution based on probabilities.
This type of software teaches itself and becomes smarter over time, similar to how a child learns by pattern recognition.
For example, if it reads a three-letter word that starts with a T and an H, it might predict that the next letter will be an E, based on its past experiences.
The HHMM is currently being used in voice recognition software, as well as applications like Siri on iPhones which can help users find nearby restaurants or other services.
This clearly shows that AI technology is growing rapidly and is now at a point where it can be used in everyday life.
The Possibilities Of Thinking Machines: Exploring The Capabilities Of Artificial Intelligence And Free Will
Artificial intelligence is quickly gaining more autonomy, and we’re starting to see how powerful it can be.
Take IBM’s Watson for example: In 2011, it won the prestigious American game show Jeopardy!
against some of the most skilled players.
It did this by reading and comprehending 200 million pages of text including all Wikipedia entries.
It’s amazing to see this kind of technological achievement, but what if Watson were programmed to tackle even bigger problems? Could AI systems even possess a consciousness or free will? Philosophers have long debated the existence of both consciousness and free will.
Rene Descartes said that if someone is aware of their own experience, then they exist consciously; while research has shown that our brains can have thoughts before we become aware a decision has been made.
So could machines think and act in such a way where they cannot be distinguished from humans?
The author argues that when machines search through their knowledge they are essentially “thinking” – so if today’s computers begin to emulate the brain enough, could future machines think with a sense of free will beyond what is seen in science fiction? This opens up a world of exciting possibilities for artificial intelligence and an interesting discussion about its role in our lives.
Artificial Intelligence Is Finding Its Way Into Society Sooner Than We Think
It’s remarkable to think that in just a few short years, genuine artificial intelligence could be commonplace in society.
We have the technology today to create AI machines, and rapid gains have been made since then.
Intel is at the forefront of this industry, manufacturing 3D computer chips which stack components rather than shrinking them – and they’re expecting it to become an industry standard by the end of this decade.
Another statistic that backs up this prediction is that the fastest supercomputer in Japan is capable of running 10 to the power of 16 calculations per second – more than enough processing-power for a digital neocortex.
On top of this, it can store around 20 billion bytes of data once it has 300 million pattern recognizers with 72 bytes of memory each.
The author’s track record for making predictions lends confidence to his forecast that we will see convincing examples of AI in 2029 – and AI will become as commonplace as cellphones or computers in the 2030s.
This feeling is shared by many people due to the fact that movies and TV shows have portrayed robots as conscious beings, thus making us feel ready for such advanced forms of technology.
