Connect with the CTML community! Next week’s seminar on Wed, Jan 28, will feature CTML GSR Kaitlyn Lee. The seminar will take place at 12 PM in BWW, 5th Fl, Rm 5401. Please note that this week’s session will be open exclusively to the CTML and UC Berkeley Community.
Connect with the Center for Targeted Machine Learning and Causal Inference (CTML) community! Next week’s seminar on Wednesday, January 28th, will feature CTML GSR Kaitlyn Lee presenting her talk, "Improving Precision through Covariate Adjustment in RCTs with Binary Outcomes." The seminar will take place at 12:00 PM in Berkeley Way West, 5th Floor, Room 5401. Please note that this week’s session will be open exclusively to the CTML and UC Berkeley community. Abstract: Covariate adjustment is a general method for improving precision when estimating treatment effects in randomized trials and is recommended by the FDA in its recent guidance when baseline variables are prognostic for the primary outcome. In this talk, we review the principles underlying covariate adjustment, with a focus on standardization, a method highlighted in the guidance for estimating the marginal treatment effect. We concentrate on settings with binary outcomes, describing practical implementation of the estimator and discussing open questions related to variance estimation and finite-sample performance.

The CTML Spring Seminar Series kicks off next Wednesday, January 21, with a talk by CTML GSR Andy Kim: “Predicting Loss to Follow-Up Under Resource Constraints: Leveraging Registry-Linked Mobile Health Data in Trauma Care.” Join us at 12:00 PM in Berkeley Way West, 5th Floor, Room 5401.
The Center for Targeted Machine Learning and Causal Inference (CTML) Spring Seminar Series kicks off next Wednesday, January 21, with a talk by CTML GSR Andy Kim: “Predicting Loss to Follow-Up Under Resource Constraints: Leveraging Registry-Linked Mobile Health Data in Trauma Care.” Join us at 12:00 PM in Berkeley Way West, 5th Floor, Room 5401. Abstract: Traumatic injury remains a leading cause of morbidity and mortality in sub-Saharan Africa, with a substantial proportion of adverse outcomes occurring after hospital discharge due to missed follow-up care. Leveraging linked-data from the Cameroon Trauma Registry (CTR) and Mobile Health (mHealth) follow-up system, I use predictive ensemble super learning methods to construct risk scores for loss to follow-up and evaluate models using recall-based metrics most relevant under resource constraints (i.e. who to prioritize calling given limited funding, staff, etc.). By framing loss to follow-up as a prioritization problem rather than a classification task, this work highlights how context-driven choices of loss functions and performance metrics shape predictive modeling strategies in applied settings.

Huge thank you to Dr. Alejandro Schuler, Assistant Professor in Residence at UC Berkeley Biostatistics and CTML faculty member, for his continued efforts with CTML and for his talk at the Gilead Health Equity Partnership (GHEP) Seminar Series titled " Increasing the Efficiency of Randomized Trials with Machine Learning." Stay tuned for more cutting-edge conversations in our ongoing CTML × Gilead Health Equity Partnership (GHEP) Series in the coming weeks and on our website! Trials enroll a large number of subjects in order to attain power, making them expensive and time-consuming. However, advancements in machine learning can make adjusted trial analyses more efficient, yielding smaller confidence intervals and p-values without sacrificing control of false positives. Adjustment works by explaining away within-treatment-group variability in the outcome using associated variability in baseline covariates, similar to stratification. Therefore, the key parameter that determines power and confidence of an adjusted analysis is how predictive the baseline covariates are for the outcome. Machine learning models often predict better than linear models and therefore they boost power. The power gain is predictable if we can accurately anticipate model performance, which allows us to trade power gains with the same sample size for smaller trials with equal power. In some settings, strongly predictive baseline information like images and free text are captured but never exploited for adjustment because they are not tabular data. Use of these data could therefore hugely increase power or decrease sample sizes, which I propose to enable using multimodal foundation models.

Continuing our CTML Seminar Series is CTML GSR, Yi Li. His talk, "Targeted Deep Architectures: A TMLE-Based Framework for Robust Causal Inference in Neural Networks" will take place on October 29th at 12:00PM at Berkeley Way West, 5th Floor, Room 5401. You won't want to miss it! Modern neural networks excel at prediction but often produce biased estimates and unreliable uncertainty for causal target parameters(e.g., average treatment effects or entire survival curves). This talk introduces Targeted Deep Architectures (TDA), a framework that embeds a targeted maximum likelihood–style update directly into a network’s parameter space. TDA freezes most weights, identifies a small “targeting” subset, and projects influence functions onto network gradients to obtain a targeting direction that iteratively removes first‑order bias. The resulting universal targeting gradient enables simultaneous debiasing of multidimensional parameters—for example, an entire survival curve—without cumbersome post‑hoc fluctuations or specialized losses. If time permits, I will also present our new work on weighted‑path updates for simultaneous targeting of multidimensional parameters, where per‑component targeting directions are combined via statistically informed weights to produce stable, coherent updates and practical convergence criteria. The framework is model‑agnostic and integrates seamlessly with modern deep architectures.

The next talk in our CTML Seminar Series is coming up on October 15th! Join us for an engaging discussion led by Michael Rosenblum, Ph.D.(link is external), Professor of Biostatistics at Johns Hopkins Bloomberg School of Public Health, on "Methodological Problems in Every Black-Box Study of Forensic Firearm Comparisons." This talk will take place at 12:00PM at Berkeley Way West, 5th Floor, Room 5401. Reviews conducted by the National Academy of Sciences (2009) and the President’s Council of Advisors on Science and Technology (2016) concluded that the field of forensic firearm comparisons has not been demonstrated to be scientifically valid. Scientific validity requires adequately designed studies of firearm examiner performance in terms of accuracy, repeatability, and reproducibility. Researchers have performed “black-box” studies with the goal of estimating these performance measures. As statisticians with expertise in experimental design, we conducted a literature search of such studies to date and then evaluated the designand statistical analysis methods used in each study. Our conclusion is that all studies in our literature search have methodological flaws that are so grave that they render the studies invalid, that is, incapable of establishing scientific validity of the field of firearms examination. Notably, error rates among firearms examiners, both collectively and individually, remain unknown. Therefore, statements about the common origin of bullets or cartridge cases that are based on examination of “individual” characteristics do not have a scientific basis. We provide some recommendations for the design and analysis of future studies.

Don't miss the next session of the CTML Seminar Series on October 1st, where Wenxin Zhang will discuss "Efficient Statistical Estimation for Sequential Adaptive Experiments with Implications for Adaptive Designs." This talk will take place from 12:00PM-1:00PM at Berkeley Way West, 5th Floor, Room 5401. Adaptive designs are increasingly used in clinical trials and online experiments to improve participant outcomes by dynamically updating treatment allocation based on accumulating data. At the end of adaptive experiments, it is often desirable to answer various causal questions based on the observed data. However, the adaptive nature of such experiments and the resulting dependence among observations pose significant challenges for providing statistical inference of causal estimands. Building upon the Targeted Maximum Likelihood Estimation (TMLE) literature that has provided valid statistical inference tailored to adaptive experimental settings, I will discuss our recent advance in efficient statistical inference under relaxed assumptions of adaptive experiments, with their implications for improving adaptive designs.
