MambaMixer: Efficient Selective State Space Models with Dual Token and Channel Selection

no code implementations29 Mar 2024 Ali Behrouz, Michele Santacatterina, Ramin Zabih

Motivated by the success of SSMs, we present MambaMixer, a new architecture with data-dependent weights that uses a dual selection mechanism across tokens and channels, called Selective Token and Channel Mixer.

Stable Estimation of Survival Causal Effects

no code implementations1 Oct 2023 Khiem Pham, David A. Hirshberg, Phuong-Mai Huynh-Pham, Michele Santacatterina, Ser-Nam Lim, Ramin Zabih

Our experiments on synthetic and semi-synthetic data demonstrate that our method has competitive bias and smaller variance than debiased machine learning approaches.

A Fast Bootstrap Algorithm for Causal Inference with Large Data

1 code implementation6 Feb 2023 Matthew Kosko, Lin Wang, Michele Santacatterina

The bag of little bootstraps has been proposed in non-causal settings for large data but has not yet been applied to evaluate the properties of estimators of causal effects.

Kernel Optimal Orthogonality Weighting: A Balancing Approach to Estimating Effects of Continuous Treatments

no code implementations26 Oct 2019 Nathan Kallus, Michele Santacatterina

In this paper, we propose Kernel Optimal Orthogonality Weighting (KOOW), a convex optimization-based method, for estimating the effects of continuous treatments.

Optimal Estimation of Generalized Average Treatment Effects using Kernel Optimal Matching

1 code implementation13 Aug 2019 Nathan Kallus, Michele Santacatterina

In causal inference, a variety of causal effect estimands have been studied, including the sample, uncensored, target, conditional, optimal subpopulation, and optimal weighted average treatment effects.

More robust estimation of sample average treatment effects using Kernel Optimal Matching in an observational study of spine surgical interventions

1 code implementation10 Nov 2018 Nathan Kallus, Brenton Pennicooke, Michele Santacatterina

Inverse probability of treatment weighting (IPTW), which has been used to estimate sample average treatment effects (SATE) using observational data, tenuously relies on the positivity assumption and the correct specification of the treatment assignment model, both of which are problematic assumptions in many observational studies.

Optimal Balancing of Time-Dependent Confounders for Marginal Structural Models

1 code implementation4 Jun 2018 Nathan Kallus, Michele Santacatterina

Marginal structural models (MSMs) estimate the causal effect of a time-varying treatment in the presence of time-dependent confounding via weighted regression.
