	abstract = {Learning from the data stored in a database is an important function
increasingly available in relational engines. Methods using
lower precision input data are of special interest given their overall
higher efficiency. However, in databases, these methods have a
hidden cost: the quantization of the real value into a smaller number
is an expensive step. To address this issue, we present MLWeaving,
a data structure and hardware acceleration technique intended
to speed up learning of generalized linear models over low
precision data. MLWeaving provides a compact in-memory representation
that enables the retrieval of data at any level of precision.
MLWeaving also provides a highly efficient implementation
of stochastic gradient descent on FPGAs and enables the dynamic
tuning of precision, instead of using a fixed precision level during
learning. Experimental results show that MLWeaving converges
up to 16 faster than low-precision implementations of first-order
methods on CPUs. },

@inproceedings{abc,
	abstract = {The ability to perform machine learning (ML) tasks in a database
management system (DBMS) provides the data analyst with a powerful
tool. Unfortunately, integration of ML into a DBMS is challenging
for reasons varying from differences in execution model to
data layout requirements. In this paper, we assume a column-store
main-memory DBMS, optimized for online analytical processing,
as our initial system. On this system, we explore the integration of
coordinate-descent based methods working natively on columnar
format to train generalized linear models. We use a cache-efficient,
partitioned stochastic coordinate descent algorithm providing linear
throughput scalability with the number of cores while preserving
convergence quality, up to 14 cores in our experiments.
Existing column oriented DBMS rely on compression and even
encryption to store data in memory. When those features are considered,
the performance of a CPU based solution suffers. Thus,
in the paper we also show how to exploit hardware acceleration
as part of a hybrid CPU+FPGA system to provide on-the-fly data
transformation combined with an FPGA-based coordinate-descent
engine. The resulting system is a column-store DBMS with its important
features preserved (e.g., data compression) that offers high
performance machine learning capabilities.},

	abstract = {Previous research shows that eye-tracking data
contains information about the lexical and syntactic
properties of text, which can be used to
improve natural language processing models.
In this work, we leverage eye movement features
from three corpora with recorded gaze
information to augment a state-of-the-art neural
model for named entity recognition (NER)
with gaze embeddings. These corpora were
manually annotated with named entity labels.
Moreover, we show how gaze features, generalized
on word type level, eliminate the need
for recorded eye-tracking data at test time. The
gaze-augmented models for NER using tokenlevel
and type-level features outperform the
baselines. We present the benefits of eyetracking
features by evaluating the NER models
on both individual datasets as well as in
cross-domain settings.},

	abstract = {Decision tree ensembles are commonly used in a wide range of applications and becoming the de facto algorithm for decision tree based classifiers. Different trees in an ensemble can be processed in parallel during tree inference, making them a suitable use case for FPGAs. Large tree ensembles, however, require careful mapping of trees to on-chip memory and management of memory accesses. As a result, existing FPGA solutions suffer from the inability to scale beyond tens of trees and lack the flexibility to support different tree ensembles. In this paper we present an FPGA tree ensemble classifier together with a software driver to efficiently manage the FPGA{\textquoteright}s memory resources. The classifier architecture efficiently utilizes the FPGA{\textquoteright}s resources to fit half a million tree nodes in on-chip memory, delivering up to 20{\texttimes} speedup over a 10-threaded CPU implementation when fully processing the tree ensemble on the FPGA. It can also combine the CPU and FPGA to scale to tree ensembles that do not fit in on-chip memory, achieving up to an order of magnitude speedup compared to a pure CPU implementation. In addition, the classifier architecture can be programmed at runtime to process varying tree ensemble sizes.},

	abstract = {Stochastic gradient descent (SGD) is a commonly used algorithm for training linear machine learning models. Based on vector algebra, it benefits from the inherent parallelism available in an FPGA. In this paper, we first present a single-precision floating-point SGD implementation on an FPGA that provides similar performance as a 10-core CPU. We then adapt the design to make it capable of processing low-precision data. The low-precision data is obtained from a novel compression scheme-called stochastic quantization, specifically designed for machine learning applications. We test both full-precision and low-precision designs on various regression and classification data sets. We achieve up to an order of magnitude training speedup when using low-precision data compared to a full-precision SGD on the same FPGA and a state-of-the-art multi-core solution, while maintaining the quality of training. We open source the designs presented in this paper.},

	abstract = {Populating a database with unstructured information is a long-standing problem in industry and research that encompasses problems of extraction, cleaning, and integration. Recent names used for this problem include dealing with dark data and knowledge base construction (KBC). In this work, we describe DeepDive, a system that combines database and machine learning ideas to help develop KBC systems, and we present techniques to make the KBC process more efficient. We observe that the KBC process is iterative, and we develop techniques to incrementally produce inference results for KBC systems. We propose two methods for incremental inference, based respectively on sampling and variational techniques. We also study the tradeoff space of these methods and develop a simple rule-based optimizer. DeepDive includes all of these contributions, and we evaluate DeepDive on five KBC systems, showing that it can speed up KBC inference tasks by up to two orders of magnitude with negligible impact on quality.},

	abstract = {DeepDive is a system for extracting relational databases from dark data: the mass of text, tables, and images that are widely collected and stored but which cannot be exploited by standard relational tools. If the information in dark data - scientific papers, Web classified ads, customer service notes, and so on - were instead in a relational database, it would give analysts a massive and valuable new set of "big data." DeepDive is distinctive when compared to previous information extraction systems in its ability to obtain very high precision and recall at reasonable engineering cost; in a number of applications, we have used DeepDive to create databases with accuracy that meets that of human annotators. To date we have successfully deployed DeepDive to create data-centric applications for insurance, materials science, genomics, paleontologists, law enforcement, and others. The data unlocked by DeepDive represents a massive opportunity for industry, government, and scientific researchers. DeepDive is enabled by an unusual design that combines large-scale probabilistic inference with a novel developer interaction cycle. This design is enabled by several core innovations around probabilistic training and inference.},

@article{abc,
	abstract = {We present ZipML, the first framework for training dense generalized linear models using end-to-end low-precision representation--in ZipML, all movements of data, including those for input samples, model, and gradients, are represented using as little as two bits per component. Within our framework, we have successfully compressed, separately, the input data by 16x, gradient by 16x, and model by 16x while still getting the same training result. Even for the most challenging datasets, we find that robust convergence can be ensured using only an end-to-end 8-bit representation or a 6-bit representation if only samples are quantized. Our work builds on previous research on using low-precision representations for gradient and model in the context of stochastic gradient descent. Our main technical contribution is a new set of techniques which allow the training samples to be processed with low precision, without affecting the convergence of the algorithm. In turn, this leads to a system where all data items move in a quantized, low precision format. In particular, we first establish that randomized rounding, while sufficient when quantizing the model and the gradients, is biased when quantizing samples, and thus leads to a different training result. We propose two new data representations which converge to the same solution as in the original data representation both in theory and empirically and require as little as 2-bits per component. As a result, if the original data is stored as 32-bit floats, we decrease the bandwidth footprint for each training iteration by up to 16x. Our results hold for models such as linear regression and least squares SVM. ZipML raises interesting theoretical questions related to the robustness of SGD to approximate data, model, and gradient representations. We conclude this working paper by a description of ongoing work extending these preliminary results. },

@inproceedings{abc,
	abstract = {Many problems in machine learning can be solved by rounding the solution of an appropriate linear program (LP). This paper shows that we can recover solutions of comparable quality by rounding an approximate LP solution instead of the ex- act one. These approximate LP solutions can be computed efficiently by applying a parallel stochastic-coordinate-descent method to a quadratic-penalty formulation of the LP. We derive worst-case runtime and solution quality guarantees of this scheme using novel perturbation and convergence analysis. Our experiments demonstrate that on such combinatorial problems as vertex cover, independent set and multiway-cut, our approximate rounding scheme is up to an order of magnitude faster than Cplex (a commercial LP solver) while producing solutions of similar quality.},
