Softmax Tree: An Accurate, Fast Classifier When the Number of Classes Is Large

no code implementations EMNLP 2021 Arman Zharmagambetov, Magzhan Gabidolla, Miguel A. Carreira-Perpinan

Classification problems having thousands or more classes naturally occur in NLP, for example language models or document classification.

Smaller, more accurate regression forests using tree alternating optimization

no code implementations ICML 2020 Arman Zharmagambetov, Miguel Carreira-Perpinan

We show that using TAO with the bagging approach produces much better forests than random forests, Adaboost or gradient boosting in every dataset we have tried across a wide range of input and output dimensionality and sample size.

GenCO: Generating Diverse Solutions to Design Problems with Combinatorial Nature

no code implementations3 Oct 2023 Aaron Ferber, Arman Zharmagambetov, Taoan Huang, Bistra Dilkina, Yuandong Tian

Generating diverse objects (e. g., images) using generative models (such as GAN or VAE) has achieved impressive results in the recent years, to help solve many design problems that are traditionally done by humans.

Towards Better Decision Forests: Forest Alternating Optimization

no code implementations CVPR 2023 Miguel Á. Carreira-Perpiñán, Magzhan Gabidolla, Arman Zharmagambetov

However, unlike for most other models, such as neural networks, optimizing forests or trees is not easy, because they define a non-differentiable function.

Faster Neural Net Inference via Forests of Sparse Oblique Decision Trees

no code implementations29 Sep 2021 Yerlan Idelbayev, Arman Zharmagambetov, Magzhan Gabidolla, Miguel A. Carreira-Perpinan

We show that neural nets can be further compressed by replacing layers of it with a special type of decision forest.

Sparse Oblique Decision Trees: A Tool to Understand and Manipulate Neural Net Features

no code implementations7 Apr 2021 Suryabhan Singh Hada, Miguel Á. Carreira-Perpiñán, Arman Zharmagambetov

The widespread deployment of deep nets in practical applications has lead to a growing desire to understand how and why such black-box methods perform prediction.

An Experimental Comparison of Old and New Decision Tree Algorithms

no code implementations8 Nov 2019 Arman Zharmagambetov, Suryabhan Singh Hada, Miguel Á. Carreira-Perpiñán, Magzhan Gabidolla

This paper presents a detailed comparison of a recently proposed algorithm for optimizing decision trees, tree alternating optimization (TAO), with other popular, established algorithms.
