Temporal and Semantic Evaluation Metrics for Foundation Models in Post-Hoc Analysis of Robotic Sub-tasks
- Recent works in Task and Motion Planning (TAMP) show that training control policies on language-supervised robot trajectories with quality labeled data improves task success rates.
- A framework is presented to decompose trajectory data into temporally bounded and natural language-based sub-tasks.
- An algorithm named SIMILARITY is introduced to measure the temporal alignment and semantic fidelity of language descriptions in sub-task decompositions.
- The framework demonstrates high scores for both temporal similarity and semantic similarity, above 90%, compared to a randomized baseline of 30% in multiple robotic environments.

Eliminating Position Bias of Language Models: A Mechanistic Approach
- Position bias is a prevalent issue in modern language models.
- The bias leads to unexpected model failures and affects performance, robustness, and reliability.
- A mechanistic analysis identifies causal attention and relative positional encodings as the sources of bias.
- A training-free zero-shot approach called PINE (Position-INvariant inferencE) is proposed to eliminate the bias and improve performance in downstream tasks.

Privacy Vulnerabilities in Marginals-based Synthetic Data
- Privacy vulnerabilities have been identified in marginals-based synthetic data generation.
- Marginals-based synthetic data generation algorithms leak information about individuals that can be recovered more efficiently than previously understood.
- A membership inference attack, MAMA-MIA, has been developed to exploit these vulnerabilities.
- The attack allows for more accurate and faster learning of hidden data compared to other leading attacks.

Assessing and improving reliability of neighbor embedding methods: a map-continuity perspective
- Neighbor embedding methods, such as t-SNE and UMAP, are widely used for visualizing high-dimensional data.
- A lack of data-independent notions of embedding maps in these methods can introduce misleading visual artifacts.
- Researchers have introduced LOO-map, a framework that extends embedding maps to the entire input space, aiming to improve reliability.
- Two types of diagnostic scores have been developed to detect unreliable embedding points and improve hyperparameter selection.

1-2-3-Go! Policy Synthesis for Parameterized Markov Decision Processes via Decision-Tree Learning and Generalization
- A learning-based approach is proposed to synthesize policies for huge parameterized Markov decision processes (MDPs).
- The method generalizes optimal policies obtained from model-checking small instances to larger ones using decision-tree learning.
- By bypassing the need for explicit state-space exploration of large models, the method provides a practical solution to the state-space explosion problem.
- Experimental results show that the policies perform well even for models beyond the reach of state-of-the-art analysis tools.
