Game-playing AI with Swift for Tensor Flow (S4TF) Final Exam Answers – Cognitive Class

Question 1: Which tier(s) of IBM Cloud require payment information on file?

• Lite
• Trial
• Pay-as-you-go

Question 2: Why would you want to use a single language, Swift, over many languages, each specialized for a certain task?

• It’s easier to maintain a codebase written in a single language.
• Swift is an expressive, performant, and open-source language backed by a large company (Apple).
• It’s slow to facilitate communication between components in different languages.
• It reduces the amount of “reinventing the wheel” required across a codebase.

Question 3: Does Minimax plays perfectly all the time? If so, why?

• It’s trained on a lot of game data and learns how to play perfectly.
• It brute forces a solution based off of the rules of the game, and all possible future situations.
• It’s provided optimal heuristics.
• It doesn’t always play perfectly.

Question 4: Classes are passed by reference, and structs are always, indiscriminately passed by value.

• A variable within a struct/class/enum.
• A function within a struct/class/enum that’s accessed like a property.

Question 6: Why is Minimax penalized for looking at moves deeper into the game tree?

• To improve performance by looking at a more shallow game tree.
• So Minimax takes into account how straightforward a move is.
• To make Minimax more accurate.

Note: Make sure you select all of the correct options—there may be more than one!

Question 7: Why is Reinforcement Learning important?

• It’s more accurate than other training methods.
• It can learn by trial and error.

Introduction to Game-playing AI with Swift for TensorFlow (S4TF)

Game-playing AI with Swift for TensorFlow (S4TF) is an exciting area where you can combine the power of Swift programming language with the flexibility and efficiency of TensorFlow to create intelligent agents capable of playing and mastering various games. Here’s an introduction to get you started:

1. Understanding Swift for TensorFlow (S4TF):
   • Swift for TensorFlow is an open-source machine learning library developed by Google and the Swift community.
   • It seamlessly integrates Swift programming language with TensorFlow, allowing you to leverage Swift’s expressive syntax and powerful features for building machine learning models.
2. Game-playing AI:
   • Game-playing AI involves creating intelligent agents that can play and excel at various games.
   • These agents typically utilize techniques from reinforcement learning, a branch of machine learning where an agent learns to make decisions by interacting with an environment and receiving feedback in the form of rewards.
3. Getting Started:
   • Install Swift for TensorFlow: Begin by installing Swift for TensorFlow on your system. You can find installation instructions on the official Swift for TensorFlow GitHub repository.
   • Familiarize Yourself with Swift: If you’re new to Swift, it’s essential to understand the basics of the language, including variables, control flow, functions, and object-oriented programming concepts.
   • Learn TensorFlow Basics: While Swift for TensorFlow abstracts many complexities, having a basic understanding of TensorFlow concepts such as tensors, operations, and graphs will be beneficial.
   • Choose a Game: Select a game you want your AI agent to play. Popular choices include classic board games like chess, Go, or video games like Atari games.
   • Define the Environment: Set up the game environment in a way that your AI agent can interact with it. This may involve creating a simulator or using existing game environments provided by libraries like Gym or Swift for TensorFlow’s own SwiftAI.
   • Implement the AI Agent: Develop an AI agent using reinforcement learning techniques such as Q-learning, Deep Q-Networks (DQN), or policy gradient methods like REINFORCE. Implement the agent’s actions, rewards, and learning algorithms in Swift.
   • Train and Evaluate: Train your AI agent using the game environment. Continuously evaluate its performance and tweak the learning parameters to improve its gameplay.
4. Advanced Techniques:
   • As you become more comfortable with game-playing AI, you can explore more advanced techniques such as deep reinforcement learning, which involves using deep neural networks to approximate the Q-values or policy function.
   • You can also experiment with other algorithms such as Monte Carlo Tree Search (MCTS) for games that have a high branching factor like Go.
5. Resources:
   • Swift for TensorFlow documentation and tutorials provide a wealth of information to help you get started.
   • Books and online courses on reinforcement learning and game-playing AI can deepen your understanding of the concepts and techniques involved.
   • GitHub repositories and online communities often share code and insights into implementing game-playing AI with Swift for TensorFlow.

By diving into game-playing AI with Swift for TensorFlow, you’ll not only learn about machine learning techniques but also hone your Swift programming skills while creating intelligent agents capable of mastering various games.
