Tasks

Architecture & Strategy

  • 🔄 PhD Application Prep — Prepare summer research summary, consult mentors about recommendation letters, and research target programs.
  • 🔄 Execute Data Migration — Run the parallel rsync script to move ’tangzijia’ and ‘RoboMemory’ data (approx. 2-3TB) to XYFS02.
  • 🔄 Qualcomm W4A4 Quantization Research — Investigate hardware/operator limitations preventing successful W4A4 quantization for VLA models.
  • ✅ Homepage Rebranding — Created a new homepage themed around ‘AI Companion Harness’, featuring an interactive demo of task statuses (Done, In-progress, Blocked) and evidence tracking.
  • 🔄 RoboMME CVPR Decision — Evaluate research progress to make a go/no-go decision for CVPR 2027 submission.
  • ✅ Visual Style Unification — Applied a consistent visual identity (beige background, green accents, improved typography) across all existing posts, Leetcode, BugJournal, and Benchmark sections.
  • ✅ Data Migration Planning — Identify source and destination paths, distinguish between different data trees, and estimate migration time.

Implementation & Fixes

  • ✅ Site-wide Deployment — Deployed the updated homepage, restructured posts, and customized styles to GitHub Pages and verified live URLs.
  • ✅ Academic Deadline Management — Submitted overdue MARSCI and DOCST assignments.
  • ✅ SSH Configuration Update — Prepare new SSH config entries for the new node ‘deeplearni-1091815’ and the updated ProxyCommand.
  • 🔄 AWS Credits Application — Initial steps taken to navigate the AWS Startup/Activate application flow using the browser agent.

Problems & Solutions

Critical Issues

1. RL agent performing sub-optimally when given ’early’ access to items/tools in the simulator.

Solution: Conducted rollout-based policy evaluation and found that ‘use tools at near-failure state’ matches the baseline best-practice.

Key Insight: RL exploration in restricted environments can lead to ’early-use’ habits which are detrimental to long-term success in high-entropy tasks.

2. Potential for content corruption during large-scale CSS/layout changes and style clashes in Benchmark reports.

Solution: Implemented Python verification scripts to compare article bodies before/after updates and manually patched Plotly HTML templates to align color palettes.

Key Insight: Automated content validation is critical when performing systemic aesthetic overhauls.

3. Potential confusion regarding the location and structure of the 1.4T ‘RoboMemory’ data.

Solution: The AI performed a structural analysis and realized ‘RoboMemory’ was a subdirectory within ’tangzijia’, simplifying the migration logic.

Key Insight: Systematic directory analysis can prevent redundant or incorrect data migration paths.

4. Git/Shell operations blocked by repository-specific ‘companion guard’ security policy in ‘fail-closed’ mode.

Solution: Identified the refusal as a deliberate human-in-the-loop policy; AI provided manual instructions for user execution and suggested adjustment of security hooks.

Key Insight: The security layer treats sensitive commands as human-only actions to ensure accountability.

Human vs AI Approaches

Strategic Level

Strategic Life Planning

Role Approach
Human Human provided structural constraints (meetings, class schedules, personal goals) and requested macro-level prioritization.
AI AI initially attempted granular tasking but was corrected to provide a ‘Phase-based’ strategic roadmap.

Difference Analysis: Human focuses on ‘Decision points’ (e.g., CVPR submission), while AI focuses on ‘Action points’ (e.g., running experiments).

Website Rebranding Concept

Role Approach
Human Conceptualized the ‘Harness’ identity, focusing on the visibility of AI progress and evidence.
AI Focused on technical implementation of visual changes and efficient asset management.

Difference Analysis: Human provided the strategic brand identity; AI translated it into technical Hugo templates and CSS.

Implementation Level

Data Migration Scope

Role Approach
Human Prioritized completeness for safety, deciding to migrate everything including large datasets.
AI Analyzed content to suggest specific files or broken sets to skip to optimize transfer time.

Difference Analysis: AI provided granular optimization suggestions, while the human prioritized safety through completeness.

AI Limitations

Critical Limitations

  • Inability to access browser tabs opened outside the internal environment (e.g., 3DPrinterOS) or bypass ‘fail-closed’ security hooks in Cursor.

General Limitations

  • Difficulty in completing automated high-stakes transactions (AWS credits) due to required organization-specific IDs and legal acceptance.
  • Hit usage limits during GitHub Actions status checks, requiring manual intervention for deployment confirmation.

Learnings

Key Learnings

  • VLA quantization complexity is heavily dictated by the gap between GPU-level quantization and NPU-specific compilation rules (W4A4 anatomy).
  • In robotics simulators, premature resource consumption by an RL agent can lead to catastrophic failure in long-horizon tasks.
  • Automated verification scripts (comparing text content via Python) are essential when performing large-scale CSS/Layout updates to prevent data loss.
  • When migrating large-scale datasets on HPC clusters, using a parallel rsync script is critical to avoid single-stream transfer bottlenecks.
