TODAY'S DISCUSSION
A PhD in machine learning involves exploring and developing a precise subject matteramong many machine learning subfields. In the AI industry, a PhD is appreciated asan outstanding achievement. Development in automated data analysis techniques anddecision-making needs research work in machine learning algorithms and foundations,
statistics, complexity theory, optimization, data mining, etc. This blog discusses thevarious data collection methods in the machine learning research field.
In Brief
If humans want the machines to act and them, we must seehow humans learned to walk and talk initially.
Similarly, for a machine to enact like human beings, data isrequired, deprived of data, no machine learning.
Data collection is collecting and measuring information frommany different sources.
Introduction
Contd....
The data need to be developed for artificial intelligence (AI) and machine learningsolutions.
It must be collected and stored in a way that solves the problem.
Machine learning is heavily used for business intelligence and analytics, effective websearch, robotics, smart cities, and understanding the human genome.
But there is a significant challenge for society to use the vast quantities of stored data,and due to this, science and technology have to attain huge investment incomputerization and data collection.
The created data must be indexed and published forsharing.
Some others can search the datasets for theirmachine learning tasks.
Data findings can be viewed as two steps
Data Finding
A PhD in machine learning involves exploring and developing a precise subject matteramong many machine learning subfields.
In the AI industry, a PhD is appreciated as an outstanding achievement.
Development in the automated Techniques for Data Analysis and decision makingneeds research work in machine learning algorithms and foundations, statistics,complexity theory, optimization, data mining, etc.
RESEARCH NEEDS
Data can be considered into two kinds
STRUCTURED DATA
It refers to well-defined types of data stored in search-friendlydatabases such as dates, numbers, strings, etc.
UNSTRUCTURED DATA
It is everything can be collected-but not search-friendly, suchas emails, Text files, Media files (music, videos, photos)
Types of datacollection
The aim is to discover datasets that are used to trainmachine learning models.
There are broadly three approaches in the literature
Data Discovery is required when one needs to share orsearch for new datasets and become necessary andavailable on the Website and corporate data lakes.
Data Augmentation is counterparts data discovery thatexisting datasets are improved by adding additional dataexternally
DataAcquisition
Contd....
Data Generation is used when there is no available external dataset, but it cangenerate crowdsourced or synthetic datasets instead.
The different methods are classified in Table 1.
A data collection tools should be userfriendly, support allfile types and functionalities, and protect data integrity.
Some of the best Data Collection tools for MachineLearning projects are given below.
The problem in many data science projects is findingrelevant, raw data.
The tools which allow users for fast access to substantialraw data are,
RAW DATA COLLECTION
Tools for datacollection
Contd....
It describes the automated, programmatic usage of an application to mine dataor performs the task that users would perform manually, like social media posts orimages.
Tools to extract data from the web are
Data Scraping Tools
Contd....
Octoparse: A web scraping is a non-coding tool that used to get public data.
Mozenda: A tool that doesn't require any scripts or developers to extract unstructuredweb data
This tool can also be generated by programs to get large sample sizes of data.
This data is used in training neural networks.
Synthetic Data Generator
Contd....
Pydbgen: It is a Python library that is used to produce a vast synthetic databaseas stated by the user.
Mockaroo: It is a data generator tool that allows users to create or custom CSV,SQL, JSOn and Excel datasets to test and trial software.
Few tools for generating synthetic datasets are
Contd....
Data augmentation, in some cases, is used to increase the size of an existingdataset despite gathering additional data.
For example, an image dataset is augmented by cropping, rotating, or changing theoriginal document's lighting effects.
OpenCV: In this Python library, image augmentation functions are available.
For example, features like bounding boxes, cropping, scaling, rotation, blur, filters,translation, and so on.
Data Augmentation Tools
Contd....
scikit-image: This tool is also a collection of algorithms for image processing whichare available for free of cost and restriction.
It also has provision to convert from one colour space to another space, erosion anddilation, resizing, rotating, filters, and so on.
As machine learning becomes more widely used, it becomesmore important to acquire large amounts of data and labeldata, especially for state-of-the-art neural networks.
If the current state of machine learning is available, the futureof machine learning has high opportunities for technologists.
