A Parameter-Efficient Learning Approach to Arabic Dialect Identification with Pre-Trained General-Purpose Speech Model

1 code implementation18 May 2023 Srijith Radhakrishnan, Chao-Han Huck Yang, Sumeer Ahmad Khan, Narsis A. Kiani, David Gomez-Cabrero, Jesper N. Tegner

In this work, we explore Parameter-Efficient-Learning (PEL) techniques to repurpose a General-Purpose-Speech (GSM) model for Arabic dialect identification (ADI).

Dialect Identification

Evolving Neural Networks through a Reverse Encoding Tree

1 code implementation3 Feb 2020 Haoling Zhang, Chao-Han Huck Yang, Hector Zenil, Narsis A. Kiani, Yue Shen, Jesper N. Tegner

Using RET, two types of approaches -- NEAT with Binary search encoding (Bi-NEAT) and NEAT with Golden-Section search encoding (GS-NEAT) -- have been designed to solve problems in benchmark continuous learning environments such as logic gates, Cartpole, and Lunar Lander, and tested against classical NEAT and FS-NEAT as baselines.

Algorithmic Causal Deconvolution of Intertwined Programs and Networks by Generative Mechanism

no code implementations18 Feb 2018 Hector Zenil, Narsis A. Kiani, Allan A. Zea, Jesper Tegnér

Complex data usually results from the interaction of objects produced by different generating mechanisms.

Minimal Algorithmic Information Loss Methods for Dimension Reduction, Feature Selection and Network Sparsification

2 code implementations16 Feb 2018 Hector Zenil, Narsis A. Kiani, Antonio Rueda-Toicen, Allan A. Zea, Jesper Tegnér

We introduce a family of unsupervised, domain-free, and (asymptotically) model-independent algorithms based on the principles of algorithmic probability and information theory designed to minimize the loss of algorithmic information, including a lossless-compression-based lossy compression algorithm.

An Algorithmic Information Calculus for Causal Discovery and Reprogramming Systems

no code implementations15 Sep 2017 Hector Zenil, Narsis A. Kiani, Francesco Marabita, Yue Deng, Szabolcs Elias, Angelika Schmidt, Gordon Ball, Jesper Tegnér

We demonstrate that the algorithmic information content of a system is deeply connected to its potential dynamics, thus affording an avenue for moving systems in the information-theoretic space and controlling them in the phase space.

Causal Discovery Dimensionality Reduction +1

Algorithmically probable mutations reproduce aspects of evolution such as convergence rate, genetic memory, and modularity

no code implementations1 Sep 2017 Santiago Hernández-Orozco, Narsis A. Kiani, Hector Zenil

The natural approach introduced here appears to be a better approximation to biological evolution than models based exclusively upon random uniform mutations, and it also approaches a formal version of open-ended evolution based on previous formal results.

A Decomposition Method for Global Evaluation of Shannon Entropy and Local Estimations of Algorithmic Complexity

3 code implementations1 Sep 2016 Hector Zenil, Santiago Hernández-Orozco, Narsis A. Kiani, Fernando Soler-Toscano, Antonio Rueda-Toicen

We also test the measure on larger objects including dual, isomorphic and cospectral graphs for which we know that algorithmic randomness is low.
