Setup your Push Notification Server utilizing Firebase | by Dev D

In at present’s digital age, push notifications play a vital function in participating customers and driving person retention for cell functions. Firebase Cloud Messaging (FCM) is a strong answer supplied by Google for sending push notifications to Android, iOS, and net platforms. On this article, we’ll discover how you can arrange a push notification server utilizing Firebase, permitting you to ship real-time notifications to your cell app customers effectively.

On this story, I’ll enable you arrange a Push Notification Server utilizing Java Springboot and ship Notifications to registered units.

Prerequisite :

Import your Java venture into Eclipse and add the dependencies of Firebase admin SDK to your Undertaking.

Initialise Firebase App :

Add Firebase Admin dependencies in pom.xml


com.google.firebase
firebase-admin
9.2.0

Add Firebase Configuration to your Undertaking :

@Configuration
public class FirebaseConfig {@Bean
public FirebaseApp firebaseApp() throws IOException {
FileInputStream serviceAccount = new FileInputStream("./devicecontrol.json");
FirebaseOptions choices = FirebaseOptions.builder()
.setCredentials(GoogleCredentials.fromStream(serviceAccount))
.construct();
return FirebaseApp.initializeApp(choices);
}
}

Service
Create a FCMService service class in SpringBoot App which is liable for sending messages utilizing FirebaseMessaging.

@Service
public class FCMService {personal remaining FirebaseMessaging firebaseMessaging;
@Autowired
public FCMService(FirebaseApp firebaseApp) {
this.firebaseMessaging = FirebaseMessaging.getInstance(firebaseApp);
}
public String sendMessage(FCMRequestDTO requestDTO) throws FirebaseMessagingException {
Message message = Message.builder()
.putData("title", requestDTO.getTitle())
.putData("physique", requestDTO.getMessage())
.setToken(requestDTO.getDeviceToken())
.construct();
String response = firebaseMessaging.ship(message);
return response;   
}
}

Request Mannequin :
Create a Request Mannequin that incorporates Metadata for Notification with FCM Token of Cell System.

When you have no idea how you can get FCM Token for Android units observe this hyperlink

public class FCMRequestDTO {personal String title;
personal String message;
personal String deviceToken;
public FCMRequestDTO() {
}
// Getter and Setter
}

Controller

Proper a controller that exposes the endpoint to ship notifications once you name this API :

@RestController
@RequestMapping("/api/fcm")
public class FCMController {personal remaining FCMService fcmService;
@Autowired
public FCMController(FCMService fcmService) {
this.fcmService = fcmService;
}
@PostMapping("/ship")
public ResponseEntity sendMessage(@RequestBody FCMRequestDTO requestDTO) {
strive {
return ResponseEntity.okay(fcmService.sendMessage(requestDTO));
} catch (FirebaseMessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return ResponseEntity.okay("FCM message despatched efficiently.");
}
}

Now Run this Net App and name Api from Postman like

POST : localhost:8000/api/fcm/ship

Request Physique:

{
"title":"Title",
"message":"Message",
"deviceToken":"Enter Android System FCM Token"
}

Alternatives for AI in Accessibility – A Record Aside

In studying Joe Dolson’s latest piece on the intersection of AI and accessibility, I completely appreciated the skepticism that he has for AI typically in addition to for the ways in which many have been utilizing it. Actually, I’m very skeptical of AI myself, regardless of my function at Microsoft as an accessibility innovation strategist who helps run the AI for Accessibility grant program. As with every device, AI can be utilized in very constructive, inclusive, and accessible methods; and it can be utilized in damaging, unique, and dangerous ones. And there are a ton of makes use of someplace within the mediocre center as properly.

Article Continues Beneath

I’d such as you to think about this a “sure… and” piece to enhance Joe’s put up. I’m not attempting to refute any of what he’s saying however quite present some visibility to tasks and alternatives the place AI could make significant variations for individuals with disabilities. To be clear, I’m not saying that there aren’t actual dangers or urgent points with AI that must be addressed—there are, and we’ve wanted to deal with them, like, yesterday—however I need to take some time to speak about what’s doable in hopes that we’ll get there at some point.

Joe’s piece spends a whole lot of time speaking about computer-vision fashions producing various textual content. He highlights a ton of legitimate points with the present state of issues. And whereas computer-vision fashions proceed to enhance within the high quality and richness of element of their descriptions, their outcomes aren’t nice. As he rightly factors out, the present state of picture evaluation is fairly poor—particularly for sure picture sorts—largely as a result of present AI programs study photos in isolation quite than throughout the contexts that they’re in (which is a consequence of getting separate “basis” fashions for textual content evaluation and picture evaluation). Right now’s fashions aren’t skilled to tell apart between photos which can be contextually related (that ought to most likely have descriptions) and people which can be purely ornamental (which could not want an outline) both. Nonetheless, I nonetheless suppose there’s potential on this area.

As Joe mentions, human-in-the-loop authoring of alt textual content ought to completely be a factor. And if AI can pop in to supply a place to begin for alt textual content—even when that place to begin is perhaps a immediate saying What is that this BS? That’s not proper in any respect… Let me attempt to supply a place to begin—I feel that’s a win.

Taking issues a step additional, if we will particularly practice a mannequin to investigate picture utilization in context, it might assist us extra rapidly establish which photos are more likely to be ornamental and which of them possible require an outline. That can assist reinforce which contexts name for picture descriptions and it’ll enhance authors’ effectivity towards making their pages extra accessible.

Whereas complicated photos—like graphs and charts—are difficult to explain in any type of succinct method (even for people), the picture instance shared within the GPT4 announcement factors to an fascinating alternative as properly. Let’s suppose that you simply got here throughout a chart whose description was merely the title of the chart and the type of visualization it was, resembling: Pie chart evaluating smartphone utilization to characteristic telephone utilization amongst US households making beneath $30,000 a 12 months. (That might be a reasonably terrible alt textual content for a chart since that might have a tendency to go away many questions on the information unanswered, however then once more, let’s suppose that that was the outline that was in place.) In case your browser knew that that picture was a pie chart (as a result of an onboard mannequin concluded this), think about a world the place customers might ask questions like these concerning the graphic:

Do extra individuals use smartphones or characteristic telephones?
What number of extra?
Is there a bunch of people who don’t fall into both of those buckets?
What number of is that?

Setting apart the realities of massive language mannequin (LLM) hallucinations—the place a mannequin simply makes up plausible-sounding “info”—for a second, the chance to be taught extra about photos and information on this method may very well be revolutionary for blind and low-vision of us in addition to for individuals with varied types of coloration blindness, cognitive disabilities, and so forth. It is also helpful in academic contexts to assist individuals who can see these charts, as is, to know the information within the charts.

Taking issues a step additional: What when you might ask your browser to simplify a fancy chart? What when you might ask it to isolate a single line on a line graph? What when you might ask your browser to transpose the colours of the totally different traces to work higher for type of coloration blindness you’ve gotten? What when you might ask it to swap colours for patterns? Given these instruments’ chat-based interfaces and our present skill to control photos in immediately’s AI instruments, that looks as if a chance.

Now think about a purpose-built mannequin that would extract the knowledge from that chart and convert it to a different format. For instance, maybe it might flip that pie chart (or higher but, a sequence of pie charts) into extra accessible (and helpful) codecs, like spreadsheets. That might be superb!

Matching algorithms#section3

Safiya Umoja Noble completely hit the nail on the pinnacle when she titled her e-book Algorithms of Oppression. Whereas her e-book was centered on the ways in which search engines like google reinforce racism, I feel that it’s equally true that every one pc fashions have the potential to amplify battle, bias, and intolerance. Whether or not it’s Twitter at all times displaying you the most recent tweet from a bored billionaire, YouTube sending us right into a Q-hole, or Instagram warping our concepts of what pure our bodies appear like, we all know that poorly authored and maintained algorithms are extremely dangerous. A whole lot of this stems from an absence of range among the many individuals who form and construct them. When these platforms are constructed with inclusively baked in, nevertheless, there’s actual potential for algorithm growth to assist individuals with disabilities.

Take Mentra, for instance. They’re an employment community for neurodivergent individuals. They use an algorithm to match job seekers with potential employers primarily based on over 75 information factors. On the job-seeker aspect of issues, it considers every candidate’s strengths, their vital and most well-liked office lodging, environmental sensitivities, and so forth. On the employer aspect, it considers every work surroundings, communication components associated to every job, and the like. As an organization run by neurodivergent of us, Mentra made the choice to flip the script when it got here to typical employment websites. They use their algorithm to suggest out there candidates to corporations, who can then join with job seekers that they’re enthusiastic about; decreasing the emotional and bodily labor on the job-seeker aspect of issues.

When extra individuals with disabilities are concerned within the creation of algorithms, that may scale back the possibilities that these algorithms will inflict hurt on their communities. That’s why numerous groups are so vital.

Think about {that a} social media firm’s suggestion engine was tuned to investigate who you’re following and if it was tuned to prioritize comply with suggestions for individuals who talked about comparable issues however who had been totally different in some key methods out of your present sphere of affect. For instance, when you had been to comply with a bunch of nondisabled white male teachers who discuss AI, it might recommend that you simply comply with teachers who’re disabled or aren’t white or aren’t male who additionally discuss AI. Should you took its suggestions, maybe you’d get a extra holistic and nuanced understanding of what’s occurring within the AI area. These identical programs must also use their understanding of biases about explicit communities—together with, for example, the incapacity neighborhood—to be sure that they aren’t recommending any of their customers comply with accounts that perpetuate biases in opposition to (or, worse, spewing hate towards) these teams.

Different ways in which AI can helps individuals with disabilities#section4

If I weren’t attempting to place this collectively between different duties, I’m certain that I might go on and on, offering all types of examples of how AI may very well be used to assist individuals with disabilities, however I’m going to make this final part right into a little bit of a lightning spherical. In no explicit order:

Voice preservation. You will have seen the VALL-E paper or Apple’s International Accessibility Consciousness Day announcement or you could be aware of the voice-preservation choices from Microsoft, Acapela, or others. It’s doable to coach an AI mannequin to copy your voice, which is usually a large boon for individuals who have ALS (Lou Gehrig’s illness) or motor-neuron illness or different medical situations that may result in an lack of ability to speak. That is, in fact, the identical tech that can be used to create audio deepfakes, so it’s one thing that we have to strategy responsibly, however the tech has really transformative potential.
Voice recognition. Researchers like these within the Speech Accessibility Mission are paying individuals with disabilities for his or her assist in accumulating recordings of individuals with atypical speech. As I kind, they’re actively recruiting individuals with Parkinson’s and associated situations, they usually have plans to develop this to different situations because the undertaking progresses. This analysis will end in extra inclusive information units that may let extra individuals with disabilities use voice assistants, dictation software program, and voice-response providers in addition to management their computer systems and different gadgets extra simply, utilizing solely their voice.
Textual content transformation. The present technology of LLMs is sort of able to adjusting present textual content content material with out injecting hallucinations. That is massively empowering for individuals with cognitive disabilities who might profit from textual content summaries or simplified variations of textual content and even textual content that’s prepped for Bionic Studying.

The significance of numerous groups and information#section5

We have to acknowledge that our variations matter. Our lived experiences are influenced by the intersections of the identities that we exist in. These lived experiences—with all their complexities (and joys and ache)—are priceless inputs to the software program, providers, and societies that we form. Our variations must be represented within the information that we use to coach new fashions, and the oldsters who contribute that priceless data must be compensated for sharing it with us. Inclusive information units yield extra sturdy fashions that foster extra equitable outcomes.

Desire a mannequin that doesn’t demean or patronize or objectify individuals with disabilities? Just be sure you have content material about disabilities that’s authored by individuals with a spread of disabilities, and be sure that that’s properly represented within the coaching information.

Desire a mannequin that doesn’t use ableist language? You might be able to use present information units to construct a filter that may intercept and remediate ableist language earlier than it reaches readers. That being mentioned, in terms of sensitivity studying, AI fashions received’t be changing human copy editors anytime quickly.

Desire a coding copilot that offers you accessible suggestions from the bounce? Prepare it on code that you recognize to be accessible.

I’ve little doubt that AI can and can hurt individuals… immediately, tomorrow, and properly into the longer term. However I additionally imagine that we will acknowledge that and, with a watch in direction of accessibility (and, extra broadly, inclusion), make considerate, thoughtful, and intentional adjustments in our approaches to AI that may scale back hurt over time as properly. Right now, tomorrow, and properly into the longer term.

Many due to Kartik Sawhney for serving to me with the event of this piece, Ashley Bischoff for her invaluable editorial help, and, in fact, Joe Dolson for the immediate.

Easy methods to Conduct Time Sequence Evaluation in R

Picture by Editor | Ideogram

Time collection evaluation research knowledge factors collected over time. It helps determine developments and patterns. This evaluation is beneficial in economics, finance, and environmental science. R is a well-liked instrument for conducting time collection evaluation because of its highly effective packages and features. On this essay, we are going to discover the best way to carry out time collection evaluation utilizing R.

Our High 5 Free Course Suggestions

1. Google Cybersecurity Certificates – Get on the quick observe to a profession in cybersecurity.

2. Pure Language Processing in TensorFlow – Construct NLP techniques

3. Python for All people – Develop packages to collect, clear, analyze, and visualize knowledge

4. Google IT Help Skilled Certificates

5. AWS Cloud Options Architect – Skilled Certificates

Load Libraries

Step one in time collection evaluation in R is to load the required libraries. The ‘forecast’ library gives features for time collection forecasting. The ‘tseries’ library gives statistical exams and time collection evaluation instruments.

library(forecast)
library(tseries)

Import Time Sequence Information

Import the time collection knowledge from a CSV file into R. On this instance, we use a dataset used for monetary evaluation. It tracks the motion of costs over time.

knowledge <- learn.csv ("timeseries.csv", header = TRUE)
head(knowledge)

head() head()

Create a Time Sequence Object

Convert the information right into a time collection object utilizing the ‘ts’ operate. This operate converts your knowledge right into a time collection format.

ts_data <- ts(knowledge$Value)

Plot the Time Sequence

Visualize the time collection knowledge. This helps determine developments, seasonality, and anomalies. Tendencies present long-term will increase or decreases within the knowledge. Seasonality reveals common patterns that repeat at mounted intervals. Anomalies spotlight uncommon values that stand out from the conventional sample.

visualization

ARIMA mannequin

The ARIMA mannequin is used to forecast time collection knowledge. It combines three elements: autoregression (AR), differencing (I), and shifting common (MA). The ‘auto.arima’ operate mechanically selects the most effective ARIMA mannequin based mostly on the information.

match <- auto.arima(ts_data)

Autocorrelation Perform (ACF)

The Autocorrelation Perform (ACF) measures how a time collection is correlated with its previous values. It helps determine patterns and lags within the knowledge. It exhibits these correlations at completely different time lags. The ACF plot helps decide the Transferring Common (MA) order (‘q’).

ACF ACF

Partial Autocorrelation Perform (PACF)

The Partial Autocorrelation Perform (PACF) measures the correlation of a time collection with its previous values. It excludes the results of intervening lags. It helps determine the energy of direct relationships at completely different lags. The PACF plot shows these correlations for varied time lags. The PACF plot helps determine the Auto-Regressive (AR) order (‘p’).

PACF PACF

Ljung-Field Take a look at

The Ljung-Field take a look at checks for autocorrelation within the residuals of a time collection mannequin. It exams if the residuals are random. It exams for autocorrelation at a number of lags. A low p-value suggests vital autocorrelation. This implies the mannequin may not be an excellent match.

Field.take a look at(match$residuals, lag = 20, sort = "Ljung-Field")

Box test

Residual Evaluation

Residual evaluation examines the variations between the noticed and predicted values from a time collection mannequin. It helps verify if the mannequin suits the information properly.

plot (match$residuals, predominant="Residuals of ARIMA Mannequin", ylab="Residuals")
abline(h=0, col="crimson")

Residual Analysis

Forecasting

Forecasting entails predicting future values based mostly on historic knowledge. Use the ‘forecast’ to generate these predictions.

forecast_result <- forecast (match)

Visualization of Forecasts

Visualize forecasted values with historic knowledge to check them. The ‘autoplot’ operate helps create these visualizations.

autoplot(forecast_result)

Forecast

Mannequin Accuracy

Consider the accuracy of the fitted mannequin utilizing the ‘accuracy’ operate. It gives efficiency metrics resembling Imply Absolute Error (MAE) and Root Imply Squared Error (RMSE).

Accuracy

Wrapping Up

Time collection evaluation in R begins by loading knowledge and creating time collection objects. Subsequent, carry out exploratory evaluation to seek out developments and patterns. Match ARIMA fashions to forecast future values. Diagnose the fashions and visualize the outcomes. This course of helps make knowledgeable selections utilizing historic knowledge.
