Investors Embrace Gender Diversity, Not Female CEOs: The Role of Gender in Startup Fundraising

no code implementations21 Jan 2021 Christopher Cassion, Yuhang Qian, Constant Bossou, Margareta Ackerman

In the wake of COVID-19, 2020 is seeing a notable decline in funding to female and mixed-gender teams, giving raise to an urgent need to study and correct the longstanding gender bias in startup funding allocation.

Uncovering Group Level Insights with Accordant Clustering

no code implementations7 Apr 2017 Amit Dhurandhar, Margareta Ackerman, Xiang Wang

Clustering is a widely-used data mining tool, which aims to discover partitions of similar items in data.

An Effective and Efficient Approach for Clusterability Evaluation

no code implementations22 Feb 2016 Margareta Ackerman, Andreas Adolfsson, Naomi Brownstein

We present extensive analyses of our approach for both the Dip and Silverman multimodality tests on real data as well as 17, 000 simulations, demonstrating the success of our approach as the first practical notion of clusterability.

When is Clustering Perturbation Robust?

no code implementations22 Jan 2016 Margareta Ackerman, Jarrod Moore

Clustering is a fundamental data mining tool that aims to divide data into groups of similar items.

Incremental Clustering: The Case for Extra Clusters

no code implementations NeurIPS 2014 Margareta Ackerman, Sanjoy Dasgupta

The explosion in the amount of data available for analysis often necessitates a transition from batch to incremental clustering methods, which process one element at a time and typically store only a small subset of the data.

Weighted Clustering

no code implementations8 Sep 2011 Margareta Ackerman, Shai Ben-David, Simina Brânzei, David Loker

One of the most prominent challenges in clustering is "the user's dilemma," which is the problem of selecting an appropriate clustering algorithm for a specific task.

Towards Property-Based Classification of Clustering Paradigms

no code implementations NeurIPS 2010 Margareta Ackerman, Shai Ben-David, David Loker

We propose to address this problem by distilling abstract properties of the input-output behavior of different clustering paradigms.

Measures of Clustering Quality: A Working Set of Axioms for Clustering

no code implementations NeurIPS 2008 Shai Ben-David, Margareta Ackerman

In this respect, we follow up on the work of Kelinberg, (Kleinberg) that showed an impossibility result for such axiomatization.
