PACSET (Packed Serialized Trees): Reducing Inference Latency for Tree Ensemble Deployment

no code implementations10 Nov 2020 Meghana Madhyastha, Kunal Lillaney, James Browne, Joshua Vogelstein, Randal Burns

We present methods to serialize and deserialize tree ensembles that optimize inference latency when models are not already loaded into memory.

Geodesic Learning via Unsupervised Decision Forests

no code implementations5 Jul 2019 Meghana Madhyastha, Percy Li, James Browne, Veronika Strnadova-Neeley, Carey E. Priebe, Randal Burns, Joshua T. Vogelstein

Empirical results on simulated and real data demonstrate that URerF is robust to high-dimensional noise, where as other methods, such as Isomap, UMAP, and FLANN, quickly deteriorate in such settings.

Sparse Projection Oblique Randomer Forests

2 code implementations10 Jun 2015 Tyler M. Tomita, James Browne, Cencheng Shen, Jaewon Chung, Jesse L. Patsolic, Benjamin Falk, Jason Yim, Carey E. Priebe, Randal Burns, Mauro Maggioni, Joshua T. Vogelstein

Unfortunately, these extensions forfeit one or more of the favorable properties of decision forests based on axis-aligned splits, such as robustness to many noise dimensions, interpretability, or computational efficiency.
