CEDAR-GRPO: Process-Aware Reinforcement Learning for General Abductive Reasoning in LLMs
Moein Salimi, Danial Parnian, Shaygan Adim +6
Abductive reasoning, often characterized as inference to the best explanation, is central to explanation under uncertainty, from everyday sense-making and investigation to scientif…
Wiring the 'Why': A Unified Taxonomy and Survey of Abductive Reasoning in LLMs
Moein Salimi, Shaygan Adim, Danial Parnian +3
Regardless of its foundational role in human discovery and sense-making, abductive reasoning--the inference of the most plausible explanation for an observation--has been relativel…

A Hybrid TGN-SEAL Model for Dynamic Graph Link Prediction
Nafiseh Sadat Sajadi, Behnam Bahrak, Mahdi Jafari Siavoshani
Predicting links in sparse, continuously evolving networks is a central challenge in network science. Conventional heuristic methods and deep learning models, including Graph Neura…
Extended Deep Submodular Functions
Seyed Mohammad Hosseini, Arash Jamshid, Seyed Mahdi Noormousavi +2
We introduce a novel category of set functions called Extended Deep Submodular functions (EDSFs), which are neural network-representable. EDSFs serve as an extension of Deep Submod…
Differentially Private Machine Learning-powered Combinatorial Auction Design
Arash Jamshidi, Seyed Mohammad Hosseini, Seyed Mahdi Noormousavi +1
We present a new approach to machine learning-powered combinatorial auctions, which is based on the principles of Differential Privacy. Our methodology guarantees that the auction…
An Adaptable Deep Learning-Based Intrusion Detection System to Zero-Day Attacks
Mahdi Soltani, Behzad Ousat, Mahdi Jafari Siavoshani +1
The intrusion detection system (IDS) is an essential element of security monitoring in computer networks. An IDS distinguishes the malicious traffic from the benign one and determi…
Intelligent Reflecting Surfaces for Compute-and-Forward
Mahdi Jafari Siavoshani, Seyed Pooya Shariatpanahi, Naeimeh Omidvar
Compute-and-forward is a promising strategy to tackle interference and obtain high rates between the transmitting users in a wireless network. However, the quality of the wireless…
A Variational Auto-Encoder Approach for Image Transmission in Wireless Channel
Amir Hossein Estiri, Mohammad Reza Sabramooz, Ali Banaei +3
Recent advancements in information technology and the widespread use of the Internet have led to easier access to data worldwide. As a result, transmitting data through noisy chann…
On Multi-Session Website Fingerprinting over TLS Handshake
Aida Ramezani, Amirhossein Khajehpour, Mahdi Jafari Siavoshani
Analyzing users' Internet traffic data and activities has a certain impact on users' experiences in different ways, from maintaining the quality of service on the Internet and prov…
A Content-Based Deep Intrusion Detection System
Mahdi Soltani, Mahdi Jafari Siavoshani, Amir Hossein Jahangir
The growing number of Internet users and the prevalence of web applications make it necessary to deal with very complex software and applications in the network. This results in an…
Adaptive Online Learning for Gradient-Based Optimizers
Saeed Masoudian, Ali Arabzadeh, Mahdi Jafari Siavoshani +2
As application demands for online convex optimization accelerate, the need for designing new methods that simultaneously cover a large class of convex functions and impose the lowe…
A Novel Communication Cost Aware Load Balancing in Content Delivery Networks using Honeybee Algorithm
