Google Cloud
Platform (GCP) is considered to be one of the Big 3 cloud platforms among
Microsoft Azure and AWS. GCP is widely used cloud solutions supporting AI capabilities to
design and develop smart models to turn your data into insights at a cheap,
affordable cost.
GCP offers many machine learning APIs, among which we take a look at
the 3 most popular APIs:
Cloud Speech API
A powerful API from
GCP! This enables the user to convert speech to text by using a neural network
model. This API is used to recognize over 100 languages throughout the world.
It can also support filter of unwanted noise/ content from a text, under
various types of environments. It supports context-awareness recognition,
works on any device, any platform, anywhere, including IoT. It has features like Automatic Speech Recognition (ASR), Global
Vocabulary, Streaming Recognition, Word Hints, Real-Time Audio support, Noise
Robustness, Inappropriate Content Filtering and supports for integration with
other APIs of GCP.
The architecture of the Cloud Speech API is as follows:
In other words,
this model enables speech to text conversion by ML.
The components used
by the Speech API are:
·
REST API or Google Remote Procedure Call (gRPC) API
·
Google Cloud Client Library
·
JSON API
·
Cloud DataLab
·
Cloud Data Storage
·
Cloud Endpoints
The applications of
the model include:
·
Voice user interfaces
·
Domotic appliance control
·
Preparation of structured documents
·
Aircraft / direct voice outputs
·
Speech to text processing
·
Telecommunication
It is free of charge for 15 seconds per usage, up to 60 minutes
per month. More than that will be charged at $0.006 per usage.
Now, as we have
learned about the concepts and the applications of the model, let’s learn some
use cases where we can implement the model:
·
Solving crimes with voice recognition: AGNITIO, A voice biometrics specialist
partnered with Morpho (Safran) to bring Voice ID technology into its
multimodal suite of criminal identification products.
·
Buying products and services with the
sound of your voice: Another most
popular and mainstream application of biometrics, in general, is mobile
payments. Voice recognition has also made its way into this highly competitive
arena.
·
A hands-free AI assistant that knows who you are: Any mobile phone nowadays has voice recognition software in the
form of AI machine learning algorithms.
Cloud Translation API
Natural language processing (NLP) is a part of artificial intelligence that focuses on Machine Translation (MT). MT has become
the main focus of NLP group for many years. MT deals with translating text from
the source language to text in the target language. Cloud Translation API
provides a graphical user interface to translate an inputted string of a
language to targeted language, it’s highly responsive, scalable and dynamic in
nature.
This API enables
translation among 100+ languages. It also supports language detection
automatically with accuracy. It provides a feature to read a web page contents
and translate to another language, and need not be text extracted from a document.
The Translation API supports various features such as programmatic access, text
translation, language detection, continuous updates and adjustable quota, and
affordable pricing.
The following image
shows the architecture of the translation model:
In other words, the
cloud translation API is an adaptive Machine Translation Algorithm.
The components used
by this model are:
·
REST API
·
Cloud DataLab
·
Cloud data storage
·
Clients Library
·
Cloud Endpoints
The most important
application of the model is the conversion of a regional language to a
foreign language.
The cost of text translation and language detection is $20 per 1
million characters.
Use cases
Now, as we have
learned about the concepts and applications of the API, let’s learn two use
cases where it has been successfully implemented:
·
Rule-based Machine Translation
·
Local Tissue Response to Injury and Trauma
We will discuss
each of these use cases in the following sections.
Rule-based Machine Translation
The steps to
implement rule-based Machine Translation successfully are as follows:
1.
Input text
2.
Parsing
3.
Tokenization
4.
Compare the rules to extract the meaning of prepositional phrase
5.
Find word of inputted language to word of the targeted language
6.
Frame the sentence of the targeted language
Local tissue response to injury and trauma
We can learn about
the Machine Translation process from the responses of a local tissue to
injuries and trauma. The human body follows a process similar to Machine
Translation when dealing with injuries. We can roughly describe the process as
follows:
1.
Hemorrhaging from lesioned vessels and blood clotting
2.
Blood-borne physiological components, leaking from the usually
closed sanguineous compartment, are recognized as foreign material by the
surrounding tissue since they are not tissue-specific
3.
Inflammatory response mediated by macrophages (and more rarely
by foreign-body giant cells)
4.
Resorption of blood clot
5.
Ingrowth of blood vessels and fibroblasts, and the formation of
granulation tissue
6.
Deposition of an unspecific but biocompatible type of repair
(scar) tissue by fibroblasts
Cloud Vision API
Cloud Vision API is powerful image analytic tool. It
enables the users to understand the content of an image. It helps in finding
various attributes or categories of an image, such as labels, web, text,
document, properties, safe search, and code of that image in JSON. In labels
field, there are many sub-categories like text, line, font, area, graphics,
screenshots, and points. How much area of graphics involved, text percentage,
what percentage of empty area and area covered by text, is there any image
partially or fully mapped in web are included web contents.
The document
consists of blocks of the image with detailed description, properties show that
the colors used in image is visualized. If any unwanted or inappropriate
content is removed from the image through safe search. The main features of
this API are label detection, explicit content detection, logo and landmark
detection, face detection, web detection, and to extract the text the API used Optical Character Reader (OCR) and is supported
for many languages. It does not support face recognition system.
The architecture
for the Cloud Vision API is as follows:
We can summarize
the functionalities of the API as extracting quantitative information from
images, taking the input as an image and the output as numerics and text.
The components used
in the API are:
·
Client Library
·
REST API
·
RPC API
·
OCR Language Support
·
Cloud Storage
·
Cloud Endpoints
Applications of the
API include:
·
Industrial Robotics
·
Cartography
·
Geology
·
Forensics and Military
·
Medical and Healthcare
Cost: Free of charge for the first 1,000 units per month; after
that, pay as you go.
Use cases
This technique can
be successfully implemented in:
·
Image detection using an Android or iOS mobile device
·
Retinal Image Analysis (Ophthalmology)
We will discuss
each of these use cases in the following topics.
Image detection using Android or iOS mobile device
Cloud Vision API
can be successfully implemented to detect images using your smartphone. The
steps to do this are simple:
1.
Input the image
2.
Run the Cloud Vision API
3.
Executes methods for detection of Face, Label, Text, Web and
Document properties
4.
Generate the response in the form of phrase or string
5.
Populate the image details as a text view
Retinal Image Analysis – ophthalmology
Similarly, the API
can also be used to analyze retinal images. The steps to implement this are as
follows:
1.
Input the images of an eye
2.
Estimate the retinal biomarkers
3.
Do the process to remove the effected portion without losing
necessary information
4.
Identify the location of specific structures
5.
Identify the boundaries of the object
6.
Find similar regions in two or more images
7.
Quantify the image with retinal portion damage
