[WIP] Start implementation of Tensor Logic framework

[Copilot]

Cloud agent has begun work on Adding tests for Tensor Logic CUDA implementation and will update this pull request as work progresses.

Original prompt

[Chronological Review: The conversation began with a user request to implement Tensor Logic, a framework for neural and symbolic AI based on Pedro Domingos' paper. The user provided a detailed CUDA implementation guide, outlining core principles, tensor operations, reasoning kernels, and an implementation roadmap. The user then requested guidance on how to add tests for the implementation.]

[Intent Mapping: The user explicitly requested to "Start implementation" of Tensor Logic and later asked "how do I add tests for this here," indicating a need for testing strategies related to the CUDA implementation.]

[Technical Inventory: Technologies mentioned include CUDA for GPU programming, tensor operations, and various mathematical functions (Heaviside step function, sigmoid, softmax). The implementation roadmap is divided into phases focusing on core primitives, reasoning infrastructure, embedding space reasoning, neural primitives, and learning.]

[Code Archaeology: The conversation included detailed CUDA kernel definitions for tensor operations (e.g., tensor join, projection, elementwise nonlinearities), reasoning kernels (forward and backward chaining), and neural network primitives (attention mechanisms, GNN message passing). Specific functions and structures were discussed, such as tensor_join_kernel, tensor_project_kernel, and TensorLogicTensor for memory layout.]

[Progress Assessment: The user has outlined a comprehensive implementation plan but has not yet indicated any completed tasks. The focus is on starting the implementation of core primitives.]

[Context Validation: All critical information for continuation is captured, including the need for testing strategies and the detailed CUDA implementation guide.]

[Recent Commands Analysis: The last agent command was the user asking how to add tests for the implementation. There were no tool results to summarize as this was a direct inquiry.]

1. Conversation Overview: - Primary Objectives: The user requested to "Start implementation" of Tensor Logic and later inquired about adding tests for the implementation. - Session Context: The conversation provided a detailed CUDA implementation guide for Tensor Logic, outlining core principles, tensor operations, reasoning kernels, and an implementation roadmap. - User Intent Evolution: The user initially focused on implementation details and later shifted to testing strategies.

2. Technical Foundation:

• CUDA: Used for GPU programming to implement tensor operations and reasoning kernels.

• Purpose: Structure for managing tensor data in CUDA.
• Current State: Defined but not yet implemented in the codebase.
• Key Code Segments: Includes data storage for dense and sparse tensors.
• Dependencies: Relates to various tensor operations and reasoning kernels.

4. Problem Resolution:

• Issues Encountered: None explicitly mentioned; focus is on implementation.
• Solutions Implemented: Not applicable as no tasks have been completed yet.
• Debugging Context: No ongoing troubleshooting efforts reported.
• Lessons Learned: Insights into tensor operations and their mathematical foundations.

5. Progress Tracking:

• Completed Tasks: None reported.
• Partially Complete Work: Implementation of core primitives is pending.
• Validated Outcomes: No features confirmed working through testing yet.

6. Active Work State:

• Current Focus: The user was discussing how to add tests for the CUDA implementation of Tensor Logic.
• Recent Context: The last few exchanges involved outlining the implementation guide and discussing testing strategies.
• Working Code: No specific code snippets were modified or discussed recently.
• Immediate Context: The user was seeking guidance on testing the CUDA implementation.

7. Recent Operations:

• Last Agent Commands: The user asked, "how do I add tests for this here."
• Tool Results Summary: No tool results were generated as this was a direct inquiry.
• Pre-Summary State: The agent was actively discussing testing strategies for the CUDA implementation when the token budget was exceeded.
• Operation Context: The user is looking to ensure that the implementation of Tensor Logic is thoroughly tested.

8. Continuation Plan:

• [Pending Task 1]: Develop a testing strategy for the CUDA implementation.
• [Pending Task 2]: Implement core tensor operations and reasoning kernels as outlined in the roadmap.
• [Priority Information]: Testing strategies are urgent to ensure the correctness of the implementation.
• [Next Action]: Provide guidance on how to structure tests for the CUDA kernels and overall Tensor Logic framework.

[Chronological Review: The conversation began with the user requesting the implementation of Tensor Logic, a framework for neural and symbolic AI. The us...
