Protolite: Highly Optimized Protocol Buffer Serializers
Package ‘protolite’ July 28, 2021 Type Package Title Highly Optimized Protocol Buffer Serializers Author Jeroen Ooms Maintainer Jeroen Ooms <[email protected]> Description Pure C++ implementations for reading and writing several common data formats based on Google protocol-buffers. Currently supports 'rexp.proto' for serialized R objects, 'geobuf.proto' for binary geojson, and 'mvt.proto' for vector tiles. This package uses the auto-generated C++ code by protobuf-compiler, hence the entire serialization is optimized at compile time. The 'RProtoBuf' package on the other hand uses the protobuf runtime library to provide a general- purpose toolkit for reading and writing arbitrary protocol-buffer data in R. Version 2.1.1 License MIT + file LICENSE URL https://github.com/jeroen/protolite BugReports https://github.com/jeroen/protolite/issues SystemRequirements libprotobuf and protobuf-compiler LinkingTo Rcpp Imports Rcpp (>= 0.12.12), jsonlite Suggests spelling, curl, testthat, RProtoBuf, sf RoxygenNote 6.1.99.9001 Encoding UTF-8 Language en-US NeedsCompilation yes Repository CRAN Date/Publication 2021-07-28 12:20:02 UTC R topics documented: geobuf . .2 mapbox . .2 serialize_pb . .3 1 2 mapbox Index 5 geobuf Geobuf Description The geobuf format is an optimized binary format for storing geojson data with protocol buffers. These functions are compatible with the geobuf2json and json2geobuf utilities from the geobuf npm package. Usage read_geobuf(x, as_data_frame = TRUE) geobuf2json(x, pretty = FALSE) json2geobuf(json, decimals = 6) Arguments x file path or raw vector with the serialized geobuf.proto message as_data_frame simplify geojson data into data frames pretty indent json, see jsonlite::toJSON json a text string with geojson data decimals how many decimals (digits behind the dot) to store for numbers mapbox Mapbox Vector Tiles Description Read Mapbox vector-tile (mvt) files and returns the list of layers.

Towards a Fully Automated Extraction and Interpretation of Tabular Data Using Machine Learning
UPTEC F 19050 Examensarbete 30 hp August 2019 Towards a fully automated extraction and interpretation of tabular data using machine learning Per Hedbrant Per Hedbrant Master Thesis in Engineering Physics Department of Engineering Sciences Uppsala University Sweden Abstract Towards a fully automated extraction and interpretation of tabular data using machine learning Per Hedbrant Teknisk- naturvetenskaplig fakultet UTH-enheten Motivation A challenge for researchers at CBCS is the ability to efficiently manage the Besöksadress: different data formats that frequently are changed. Significant amount of time is Ångströmlaboratoriet Lägerhyddsvägen 1 spent on manual pre-processing, converting from one format to another. There are Hus 4, Plan 0 currently no solutions that uses pattern recognition to locate and automatically recognise data structures in a spreadsheet. Postadress: Box 536 751 21 Uppsala Problem Definition The desired solution is to build a self-learning Software as-a-Service (SaaS) for Telefon: automated recognition and loading of data stored in arbitrary formats. The aim of 018 – 471 30 03 this study is three-folded: A) Investigate if unsupervised machine learning Telefax: methods can be used to label different types of cells in spreadsheets. B) 018 – 471 30 00 Investigate if a hypothesis-generating algorithm can be used to label different types of cells in spreadsheets. C) Advise on choices of architecture and Hemsida: technologies for the SaaS solution. http://www.teknat.uu.se/student Method A pre-processing framework is built that can read and pre-process any type of spreadsheet into a feature matrix. Different datasets are read and clustered. An investigation on the usefulness of reducing the dimensionality is also done.

Zhao Jerry Zhao University of California, Berkeley University of California, Berkeley University of California, Berkeley [email protected] william [email protected] [email protected] Abstract—According to recent literature, at least 25% of cycles will serialize some set of objects stored in memory to a in a modern warehouse-scale computer are spent on common portable format defined by the protobuf compiler (protoc). “building blocks” [1]. Referred to by Kanev et al. as a “datacenter The serialized objects can be sent to some remote device, tax”, these tasks are prime candidates for hardware acceleration, as even modest improvements here can generate immense cost which will then deserialize the object into its own memory and power savings given the scale of such systems. to execute on. Thus protobuf is widely used to implement One of these tasks is protocol buffer serialization and parsing. remote procedure calls (RPC), since it facilitates the transport Protocol buffers are an open-source mechanism for representing of arguments across a network.

Specifically, the encoding tasks - such as the compression/decompression of integer fields scheme enables future changes to the protobuf schema to and the encoding of variable-length strings - bottleneck the remain backwards compatible. throughput of serializing or parsing a protobuf.

They©re used both in RPC systems and for persistent storage of data in a variety of storage systems.) ● Goals: ● Simplicity ● Compatibility ● Performance 3/33 Comparison XML - Protobuf ● Readable by humans ↔ binary format ● Self-describing ↔ Garbage without .proto file ● Big files ↔ small files (3-10 times) ● Slow to serialize/parse ↔ fast (20-100 times) ● .xsd (complex) ↔ .proto (simple, less ambiguous) ● Complex access ↔ easy access 4/33 Comparison XML ± Protobuf (cntd) <person> Person { <name>John Doe</name> name: "John Doe" <email>[email protected]</email> email: "[email protected]" </person> } (== 69 bytes, 5-10©000ns to parse) (== 28 bytes, 100-200ns to parse) cout << "Name: " cout << "Name: " << person.name() << << endl; person.getElementsByTagName("nam cout << "E-mail: " << person.email() << e")->item(0)->innerText() endl; << endl; cout << "E-mail: " << person.getElementsByTagName("emai l")->item(0)->innerText() 5/33 << endl; Example message Person { required string name = 1; // name of person required int32 id = 2; // id of person optional string email = 3; // email address enum PhoneType { MOBILE = 0; HOME = 1; WORK = 2; } message PhoneNumber { required string number = 1; optional PhoneType type = 2 [default = HOME]; } 6/33 repeated PhoneNumber phone = 4; } From .proto to runtime ● Messages defined in .proto file(s) ● Compiled into source code with protoc ● C++ ● Java ● Python ● More languages via AddOns (C#, PHP, Perl, ObjC, etc) ● Usage in code ● Passed via network / files 7/33 Message Definition ● Messages defined in .proto files ● Syntax: Message [MessageName] { ..
