Rate or Fate? RLVR: Reinforcement Learning with Verifiable Noisy Rewards
Ali Rad, Khashayar Filom, Darioush Keivan +2
Reinforcement learning with verifiable rewards (RLVR) is a simple but powerful paradigm for training LLMs: sample a completion, verify it, and update. In practice, however, the ver…
TB or Not TB: Coverage-Driven Direct Preference Optimization for Verilog Stimulus Generation
Bardia Nadimi, Khashayar Filom, Deming Chen +1
With the rapid advancement of Large Language Models (LLMs), there is growing interest in applying them to hardware design and verification. Among these stages, design verification…
MBExplainer: Multilevel bandit-based explanations for downstream models with augmented graph embeddings
Ashkan Golgoon, Ryan Franks, Khashayar Filom +1
In many industrial applications, it is common that the graph embeddings generated from training GNNs are used in an ensemble model where the embeddings are combined with other tabu…
Mechanistic interpretability of large language models with applications to the financial services industry
Ashkan Golgoon, Khashayar Filom, Arjun Ravi Kannan
Large Language Models such as GPTs (Generative Pre-trained Transformers) exhibit remarkable capabilities across a broad spectrum of applications. Nevertheless, due to their intrins…
Approximation of group explainers with coalition structure using Monte Carlo sampling on the product space of coalitions and features
Konstandinos Kotsiopoulos, Alexey Miroshnikov, Khashayar Filom +1
In recent years, many Machine Learning (ML) explanation techniques have been designed using ideas from cooperative game theory. These game-theoretic explainers suffer from high com…
On marginal feature attributions of tree-based models
Khashayar Filom, Alexey Miroshnikov, Konstandinos Kotsiopoulos +1
Due to their power and ease of use, tree-based machine learning models, such as random forests and gradient-boosted tree ensembles, have become very popular. To interpret them, loc…
On the rank of the Thurston pullback map
Khashayar Filom
Under some mild assumptions, an orientation-preserving branched covering map of marked -spheres induces a pullback map between the corresponding Teichmüller spaces. By analyzing…
Results and questions on matchings in groups and vector subspaces of fields
Mohsen Aliabadi, Khashayar Filom
A matching from a finite subset of an abelian group to another subset is a bijection with the property that never lies in . A matching is cal…
Stability theory of game-theoretic group feature explanations for machine learning models
Alexey Miroshnikov, Konstandinos Kotsiopoulos, Khashayar Filom +1
In this article, we study feature attributions of Machine Learning (ML) models originating from linear game values and coalitional values defined as operators on appropriate functi…
PDE constraints on smooth hierarchical functions computed by neural networks
Khashayar Filom, Konrad Paul Kording, Roozbeh Farhoodi
Neural networks are versatile tools for computation, having the ability to approximate a broad range of functions. An important problem in the theory of deep neural networks is exp…
On the non-monotonicity of entropy for a class of real quadratic rational maps
Khashayar Filom, Kevin M. Pilgrim
We prove that the entropy function on the moduli space of real quadratic rational maps is not monotonic by exhibiting a continuum of disconnected level sets. This entropy behavior…
Topological aspects of the dynamical moduli space of rational maps
Maxime Bergeron, Khashayar Filom, Sam Nariman
We investigate the topology of the space of Möbius conjugacy classes of degree rational maps on the Riemann sphere. We show that it is rationally acyclic and we compute its fun…
On functions computed on trees
Roozbeh Farhoodi, Khashayar Filom, Ilenna Simone Jones +1
Any function can be constructed using a hierarchy of simpler functions through compositions. Such a hierarchy can be characterized by a binary rooted tree. Each node of this tree i…
Monotonicity of entropy for real quadratic rational maps
Khashayar Filom
The monotonicity of entropy is investigated for real quadratic rational maps on the real circle based on the natural partition of the corresponding modul…

Khashayar Filom
We set up a real entropy function on the space of Möbius conjugacy classes of real rational maps of degree by assigning to each class the real entr…

Khashayar Filom, Ali Kamalinejad
Given a finite index subgroup of , we investigate Belyi functions on the corresponding modular curve by introducing two methods for constructing s…
On the -invariant and the Legendre Representation of Elliptic Curves with Complex Multiplication
Khashayar Filom
By introducing a class of meromorphic functions with certain ramification structures on , a new method for the determination of the Legendre representation of elliptic…
