Demystifying Machine Learning: A Simple Guide for the Non-Tech Savvy

Machine Learning (ML) is a buzzword that’s been making waves in the tech world and beyond. But what exactly is it? For those of us who aren’t tech experts, machine learning might seem like a complex and intimidating concept. But fear not! This blog post aims to break down machine learning into simple, understandable terms.

Understanding Machine Learning

Imagine teaching a child how to recognize different types of fruits. You show them apples, bananas, oranges, and explain their unique characteristics. Over time, the child learns to identify these fruits on their own. This is, in essence, what machine learning is all about. It’s a type of artificial intelligence (AI) that involves teaching computers how to learn from data to make decisions or predictions.

How Does Machine Learning Work?

Machine learning works by feeding a computer system a lot of data, which it uses to learn patterns and make decisions. For instance, a machine learning system could be trained to recognize spam emails by analyzing thousands of emails, learning from the patterns it sees, and then using this knowledge to identify whether a new email is spam or not.

Types of Machine Learning

There are two main types of machine learning: supervised and unsupervised learning.

  • Supervised Learning: This is like teaching a child with a guidebook. You provide the computer with input data and the correct output. The system then learns the relationship between the input and output. For example, you could train a system to recognize dogs by showing it many pictures of dogs (input) and telling it that these are dogs (output).
  • Unsupervised Learning: This is like letting a child explore and learn on their own. The system is given a lot of data and must find patterns and relationships within the data itself. For example, you could give a system a bunch of news articles, and it might categorize them into different topics based on the words used in the articles.

Why is Machine Learning Important?

Machine learning is transforming the world in many ways. It’s used in healthcare to predict diseases, in finance to detect fraudulent transactions, in retail to recommend products, and much more. It’s making our lives easier, safer, and more personalized.


Machine learning might seem complex, but at its core, it’s about teaching computers to learn from data, just like how we learn from our experiences. It’s a powerful technology that’s changing the world in incredible ways, and it’s something we can all understand and appreciate.

The Consequences of Using Model-Generated Content in Training Large Language Models

In a recent study titled “The use of model-generated content in training large language models (LLMs)”, the authors delve into a critical issue that has significant implications for the field of machine learning and artificial intelligence. The paper discusses a phenomenon known as “model collapse,” which refers to the disappearance of the tails of the original content distribution in the resulting models due to the use of model-generated content in training large language models.

This issue is not isolated but is ubiquitous amongst all learned generative models. It is a matter of serious concern, especially considering the benefits derived from training with large-scale data scraped from the web.

The authors emphasize the increasing value of data collected from genuine human interactions with systems, especially in the context of the presence of content generated by large language models in data crawled from the Internet.

The paper suggests that the use of model-generated content in training large language models can lead to irreversible defects. These defects can significantly affect the performance and reliability of these models, making it a crucial area of research and development in the field of AI and machine learning.

The document provides a comprehensive analysis of the issue and offers valuable insights into the challenges and potential solutions associated with training large language models. It is a must-read for researchers, data scientists, and AI enthusiasts who are keen on understanding the intricacies of large language model training and the impact of model-generated content on these processes.

The cause of model collapse is primarily attributed to two types of errors: statistical approximation error and functional approximation error.

Statistical approximation error is the primary type of error, which arises due to the number of samples being finite, and disappears as the number of samples tends to infinity. This occurs due to a non-zero probability that information can get lost at every step of re-sampling. For instance, a single-dimensional Gaussian being approximated from a finite number of samples can still have significant errors, despite using a very large number of points.

Functional approximation error is a secondary type of error, which stems from our function approximators being insufficiently expressive (or sometimes too expressive outside of the original distribution support). For example, a neural network can introduce non-zero likelihood outside of the support of the original distribution. A simple example of this error is if we were to try fitting a mixture of two Gaussians with a single Gaussian. Even if we have perfect information about the data distribution, model errors will be inevitable.

These errors can cause model collapse to get worse or better. Better approximation power can even be a double-edged sword – better expressiveness may counteract statistical noise, resulting in a good approximation of the true distribution, but it can equally compound this noise. More often then not, we get a cascading effect where combined individual inaccuracy causes the overall error to grow. Overfitting the density model will cause the model to extrapolate incorrectly and might give high density to low-density regions not covered in the training set support; these will then be sampled with arbitrary frequency.

It’s also worth mentioning that modern computers also have a further computational error coming from the way floating point numbers are represented. This error is not evenly spread across different floating point ranges, making it hard to estimate the precise value of a given number. Such errors are smaller in magnitude and are fixable with more precise hardware, making them less influential on model collapse.

Implementing Artificial Intelligence for Non-Player Characters in Video Games

Artificial Intelligence (AI) has become an integral part of modern video game development, enhancing the gaming experience by making non-player characters (NPCs) more realistic and interactive. NPCs, controlled by the game’s AI, can exhibit complex behaviors, make decisions, and adapt to the player’s actions, thereby creating a dynamic and immersive gaming environment. This essay will explore the process of implementing AI for NPCs in video games.

Understanding AI in Video Games

AI in video games is fundamentally different from traditional AI. While traditional AI aims to create a system that can perform tasks that would require human intelligence, AI in video games is designed to create an enjoyable and engaging experience for the player. This often involves creating NPCs that behave in a believable and predictable manner, rather than exhibiting true intelligence.

AI Techniques for NPCs

  1. Finite State Machines (FSM): FSM is a simple AI technique where an NPC can be in one of a finite number of states, such as patrolling, chasing, or attacking. The NPC transitions between these states based on certain conditions, such as the player’s proximity.
  2. Behavior Trees: A more advanced technique, behavior trees, allow for more complex NPC behavior by structuring AI as a tree of tasks. These tasks can be simple actions, like moving to a location, or more complex behaviors composed of other tasks.
  3. Utility AI: This technique involves assigning a utility score to different actions based on the current state of the game. The NPC then performs the action with the highest utility score. This allows for more dynamic and adaptable NPC behavior.
  4. Machine Learning: Some games use machine learning techniques to train NPCs. This involves using large amounts of data to train an NPC to respond to different situations. This can result in more unpredictable and realistic NPC behavior.

Implementing AI for NPCs

The first step in implementing AI for NPCs is to define the desired behavior. This could be as simple as an NPC that patrols a certain area, or as complex as an NPC that can engage in combat, navigate complex environments, and interact with the player.

Once the desired behavior is defined, the appropriate AI technique can be selected. For simple behaviors, a FSM may be sufficient. For more complex behaviors, a behavior tree or utility AI may be more appropriate. If the goal is to create an NPC that can learn and adapt, machine learning techniques may be used.

After selecting the AI technique, the next step is to implement it. This involves programming the NPC to perform the desired actions and react to the game environment. This can be a complex process, requiring a deep understanding of both programming and game design.

Testing and refining the AI is a crucial part of the process. This involves playing the game and observing the NPC’s behavior to ensure it behaves as expected. If the NPC’s behavior is not as desired, the AI may need to be adjusted or a different AI technique may need to be used.


Libraries for Implementing AI in Video Games

The implementation of AI in video games has been made significantly easier with the advent of various libraries and frameworks. These tools abstract away many of the complexities associated with AI, allowing developers to focus on creating engaging and dynamic NPCs.
