What is Google Deepmind and how it is revolutionizing Artificial Intelligence

Getting your Trinity Audio player ready...

Google DeepMind is a research company in artificial intelligence (AI) which was acquired by Alphabet (Google's parent company) in 2015. Founded and headquartered in London in 2010, DeepMind is known for its significant contributions to AI research and development. The company's main emphasis is in the field of machine learning and deep learning.

The company's fundamental objective is to create AI that can learn and reason like humans. This way, the result could bring more intelligent systems capable of solving complex problems.

In this article, we will delve a little deeper into the Google DeepMind and what are its fundamental contributions to AI.

DeepMind and its contributions

1. Deep Learning and Convolutional Neural Networks (CNNs):

DeepMind pioneered the successful application of convolutional neural networks (CNNs) to object recognition in images.

This has led to a significant advancement in the field of computer vision, allowing machines to identify objects, faces and patterns in images with unprecedented accuracy.

CNNs, or Convolutional Neural Networks in English are a specialized type of deep neural network architecture. They are designed to process and analyze data that has a grid structure. This includes images and time series data. They were specially developed for computer vision tasks, where the detection and extraction of features in images are fundamental.

They were inspired by the organization of the human visual cortex, where different regions of the brain respond to specific parts of the visual field. These networks are capable of automatically capturing hierarchical and complex features, such as edges, textures and patterns, at different levels of abstraction, allowing for an effective representation of objects in images.

These characteristics have been essential in the field of computer vision. Its fundamental role is present in many applications, such as object recognition, face detection and medical image analysis.

2. AlphaGo and Board Games:

Perhaps one of DeepMind's most famous achievements was the development of AlphaGo. The program became famous in 2016, when it challenged Go world champion Lee Sedol in a series of matches. AlphaGo won four of the five matches, demonstrating AI's ability to overcome highly complex and unpredictable challenges.

Go is an ancient board game originating in China, known for its strategic complexity and vast amount of possibilities. Unlike other games, such as chess, where the number of possible moves is relatively limited, Go presents an almost unimaginable number of positions and moves.

AlphaGo is designed to master the game, a notoriously difficult challenge for traditional artificial intelligence approaches due to its complex nature and high number of possible combinations.

AlphaGo's approach involved:

Convolutional Neural Networks (CNNs):

The program used convolutional neural networks to evaluate the position of pieces on the board and identify strategic patterns.

Reinforcement Learning:

AlphaGo was trained using reinforcement learning, where it played millions of games against itself. He learned to improve his strategies from the results of these games and the rewards he obtained.

Monte Carlo Search Tree (MCTS):

AlphaGo used the MCTS technique to explore and evaluate potential moves in greater depth, helping you make more informed decisions.

AlphaGo's success has had a significant impact on the field of artificial intelligence and inspired new research and advancements. It has also opened doors to applications in areas such as medicine, scientific research and more. These are areas where AI especially can be used to solve complex problems that previously seemed insurmountable.

3. AlphaZero and matrix multiplication

Another notable achievement of DeepMind was the development of AlphaZero. It is an evolution of AlphaGo, and has become notable for its reinforcement learning capabilities, learning and mastering games through self-learning. This way, the application does not depend on human data or pre-programmed moves to act.

In addition to its achievements in board games, AlphaZero has also demonstrated the ability to accelerate the resolution of complex problems such as matrix multiplication.

Matrix multiplication is an essential calculation for various applications, ranging from displaying images on a screen to simulating complex physics systems. It is also essential in machine learning.

Thus, AlphaZero surprised by showing that its reinforcement learning and self-learning approach could be applied to accelerate matrix multiplication, breaking the record that had already stood for more than 50 years.

And to leave no doubt about its capacity, the new version, called AlphaDev, accelerated calculations even further and increased the solution for calculating items organized in a list by 70%. Furthermore, it accelerated a fundamental algorithm used in encryption by 30%.

AlphaZero has not only revolutionized the way AI learns and plays games, but has also demonstrated its ability to generate insights in other areas, accelerating computationally intensive processes.

4. Health and Science:

In addition to gaming, DeepMind is also focused on applying its technologies in domains such as healthcare and science.

In this way, DeepMind developed AI algorithms capable of analyzing medical images and assisting in medical diagnoses, as well as modeling complex molecular interactions to advance scientific research.

5. Ethics and Security:

DeepMind has also demonstrated a commitment to AI ethics and safety. The company contributed to the development of guidelines for responsible AI research by exploring ways to mitigate potential risks associated with the advancement of artificial intelligence.

In short…

Google DeepMind is revolutionizing artificial intelligence through its achievements in diverse fields, from gaming to medicine and ethics. Their research has the potential to shape the future of AI by making it more powerful, efficient and, at the same time, responsible.
