Artificial Intelligence Explained on Last Week Tonight With John Oliver

Artificial intelligence, or AI for short, is a branch of computer science that strives to replicate human cognitive activity. This includes learning, reasoning, perception and problem-solving processes.

AI has become an integral part of our lives, from self-driving cars to travel websites that find the best flights and hotels for your trip. But it also poses serious risks.

Artificial Intelligence

Artificial intelligence is a rapidly-evolving technology that will play an increasingly significant role in our lives. From self-driving cars to ChatGPT, it's becoming an integral part of our world.

AI has the potential to revolutionize our lives, yet there remain numerous concerns regarding its potential danger. Some are worried about its effect on jobs while others believe that improper usage could result in serious harm.

One of the major concerns with AI is its reliance on data sets for tasks. Researchers such as Joy Blome-Wini have observed that certain groups are often excluded from training data used by AI systems, leading to racial biases within these systems.

Another key concern is the difficulty of understanding AI programs, even by their creators. This leads to something known as the "black box problem," in which systems perform in mysterious ways that no one can explain.

We must remain vigilant, particularly as some of these programs can make unpredicted and dangerous decisions. Imagine a self-driving car that doesn't notice pedestrians because it wasn't looking for them or a chatbot who confidently provides false information without hesitation. These are all issues worth monitoring closely.

John Oliver of Last Week Tonight with John Oliver HBO tackles many of these topics and it's evident that they have done extensive research. If you want to gain more insight into how AI is impacting our lives, this episode of the popular comedy show will definitely be worth watching!

Machine Learning

Machine learning is an exciting field of artificial intelligence that enables machines to draw upon their experiences and improve over time. This type of AI finds applications across many industries, helping organizations solve issues and create new products and services.

Machine learning is an amazing technology, yet its potential uses and effects on society raise some concerns. For instance, it could be programmed to use information which reinforces existing inequities and prejudices, thus perpetuating or exacerbating discrimination or social ills.

Another concern is the reliance on inaccurate or false data. This can cause data-driven models to display extreme content or divide people.

It's essential to remember that machines are capable of making mistakes, particularly in tasks requiring high-level decision-making. For instance, a machine learning algorithm could analyze an X-ray image of a patient and conclude the image reveals tuberculosis.

Unfortunately, inaccurate results or poor outcomes for patients can occur when doctors fail to thoroughly review a patient's medical history and rule out tuberculosis. To ensure an accurate assessment, doctors must assess each patient individually based on their medical history and test for tuberculosis.

Machine learning is a sophisticated process that requires access to various data sets and algorithms. With it, computer systems can be created that perform tasks like predictions, recommendations, estimations or classifications based on past experience and predicted data.

Deep Learning

Deep Learning is a branch of Artificial Intelligence that works on creating algorithms with multiple layers. By doing so, AI can learn new tricks and make informed decisions without human input. It represents an enormous advance in machine learning technology and has enabled all manner of automated tasks to become much more efficient.

Deep learning methods utilize complex programs to simulate human intelligence, and they are commonly employed in image processing and speech recognition applications. For instance, a machine can be taught to recognize patterns of digits and letters within an image, read text messages, or even comprehend DNA sequences at a deeper level.

One of the most widely-used algorithms in image recognition is Multilayer Perceptron (MLP). This algorithm scales with model size and data size, and it can be trained using backpropagation. Furthermore, it's used to construct Convolutional Neural Networks (CNN), which are highly effective at object recognition from images.

Another deep learning method is generative models, which utilize unsupervised learning to generate new data points from existing ones. These can be employed for speech recognition, sentiment classification and machine translation applications.

Deep learning is especially effective for problems where the inputs are analog, such as images of pixels, documents with text data or audio files. These types of problems lend themselves perfectly to deep learning techniques and this field is rapidly developing in this space.

Neural Networks

Neural networks, a software solution that mimics the brain's operations with machine learning (ML) algorithms, are now widely used across various industries. Not only do they process data more quickly than traditional computers but also offer improved pattern recognition and problem-solving abilities compared to them.

Neural networks were inspired by biological nervous systems and feature several layers of processing and basic elements working simultaneously. Each layer consists of nodes or "artificial neurons" connected to one another and assigned a particular weight and threshold for processing.

When a node receives information, it checks its threshold value and then passes the input onto the next layer in the network. This layer then adds up all of the inputs from all nodes that were passed along to it.

Information is then processed and a final result presented back to the user. This intricate process of input and output can be challenging to audit for weaknesses in calculations or learning processes.

Neural networks come in various types, such as modular networks, generative adversarial networks and deep learning networks.

Neural Turing Machines

Neural Turing Machines are a type of neural network that combines standard neural networks with a computer-like memory system, enabling them to perform arbitrary algorithms orders of magnitude faster than standard neural networks can.

It is crucial to have enough memory for many neural network models, as many require vast amounts of it in order to function optimally. Recurrent neural networks like LSTM often possess large internal memories which can grow exponentially over time.

In 2014, researchers at Google Brain introduced the NTM (Neural Turing Machine). This is a generalization of LSTM networks that stores its memory externally.

The NTM architecture provides multiple independent parameters that shape how the network communicates with its memory matrix. These include memory size, read/write head count, and allowable location shift range.

Network Thumbprinting (NTM) technology enables networks to selectively read and write information to different parts of a memory matrix, similar to how CPUs and RAM communicate with one another. NTM's read/write heads can interact with memory at various levels of detail, helping save time by focusing on pertinent data. Furthermore, keeping the memory small keeps it efficient and fast for processing requests.

Neural Nets

Neural networks are a type of machine learning that utilizes thousands or millions of simple processing nodes that are tightly connected. These neurons interpret sensory data by clustering or labeling it, and they can detect patterns in images, texts, sound and time series data.

Neural networks consist of three basic layers: input layers, hidden layers and output layers. The input layer takes data from the outside world and sends it to the hidden layers for processing through weighted connections. Nodes then use activation functions to decide whether input should continue through the network or not.

Training occurs when weights and thresholds are adjusted until the trained inputs consistently produce identical outputs. Afterward, the network will continue to refine its settings until it achieves optimal performance.

A neural network can be designed in several ways. One popular type is a feed-forward neural network, which takes input data and sends it to one output node which then produces two possible outcomes: 0 or 1.

Conversely, recurrent neural networks are more complex. This type of network transmits data back into its processing nodes, allowing for theoretical "learning" and improvement within the system.

Recurrent neural networks are commonly employed in applications like text-to-speech and computer vision, where they can use their output to predict what a person will say or do.
