Detecting Meals High quality with Raspberry Pi and TensorFlow
By George Soloupis, ML Google Developer Professional (Greece)
This mission helps individuals with scent impairment by figuring out meals degradation. The thought got here abruptly when a buddy revealed that he has no sense of scent because of a motorbike crash. Even with experiences attending a variety of IT conferences, this concern was unaddressed and the ability of machine studying is one thing we may depend on. Therefore the purpose. It’s to create a prototype that’s inexpensive, correct and usable by individuals with minimal information of computer systems.
The essential setting of the meals high quality detection is that this. Raspberry Pi collects information from air sensors over time through the meals degradation course of. This single board laptop was very helpful! With the GUI, it’s straightforward to execute Python scripts and see the outcomes on display. Eight sensors collected information of the chemical components corresponding to NH3, H2s, O3, CO, and CH4. After working the prototype for someday, classes have been set following the outcomes. The primary hours of the meals out of the fridge as “good” and the remainder as “unhealthy”. Then the dataset was evaluated with the assistance of TensorFlow and the inference was achieved with TensorFlow Lite.
Since there have been no open supply prototypes on the market with comparable targets, it was a whole journey. Sensors on PCBs and standalone sensors have been used to get one of the best combination of accuracy, stability and sensitivity. A logic degree converter has been used to attenuate using resistors, and capacitors have been positioned for stability. And the consequence, a compact prototype! The Raspberry Pi may connect immediately on with slots for eight sensors. It’s developed in such a means that sensors will be changed at any time. Customers can experiment with totally different sensors. And the inference time values are despatched via the bluetooth to a cellular machine. As an finish consequence a person with no superior technical information will be capable of see meals high quality on an app constructed on Android (Kotlin).

Election Watch: Making use of ML in Analyzing Elections Discourse and Citizen Participation in Nigeria
By Victor Dibia, ML Google Developer Professional (USA)
This mission explores using GCP instruments in ingesting, storing and analyzing information on citizen participation and election discourse in Nigeria. It started on the premise that the proliferation of social media interactions gives an fascinating lens to review human habits, and ask essential questions on election discourse in Nigeria in addition to interrogate social/demographic questions.
It’s based mostly on information collected from twitter between September 2018 to March 2019 (tweets geotagged to Nigeria and tweets containing election associated key phrases). Total, the info set accommodates 25.2 million tweets and retweets, 12.6 million unique tweets, 8.6 million geotagged tweets and three.6 million tweets labeled (utilizing an ML mannequin) as political.
By analyzing election discourse, we will study just a few essential issues together with – points that drive election discourse, how social media was utilized by candidates, and the way participation was distributed throughout geographic areas within the nation. Lastly, in a rustic like Nigeria the place up to date demographics information is missing (e.g., on neighborhood buildings, wealth distribution and so on), this mission exhibits how social media can be utilized as a surrogate to deduce relative statistics (e.g., existence of diaspora communities based mostly on election dialogue and wealth distribution based mostly on machine kind utilization throughout the nation).
Knowledge for the mission was collected utilizing python scripts that wrote tweets from the Twitter streaming api (matching sure standards) to BigQuery. BigQuery queries have been then used to generate combination datasets used for visualizations/evaluation and coaching machine studying fashions (political textual content classification fashions to label political textual content and multi class classification fashions to label normal discourse). The fashions have been constructed utilizing Tensorflow 2.0 and skilled on Colab notebooks powered by GCP GPU compute VMs.

Bioacoustic Sound Detector (To establish chook calls in soundscapes)
By Usha Rengaraju, TFUG Organizer (India)
“Visionary Perspective Plan (2020-2030) for the conservation of avian range, their ecosystems, habitats and landscapes within the nation” proposed by the Indian authorities to assist in the conservation of birds and their habitats impressed me to take up this mission.
Extinction of chook species is an rising international concern because it has a huge effect on meals chains. Bioacoustic monitoring can present a passive, low labor, and cost-effective technique for learning endangered chook populations. Latest advances in machine studying have made it doable to routinely establish chook songs for frequent species with ample coaching information. This innovation makes it simpler for researchers and conservation practitioners to precisely survey inhabitants developments they usually’ll be capable of recurrently and extra successfully consider threats and modify their conservation actions.
This mission is an implementation of a Bioacoustic monitor utilizing Masked Autoencoders in TensorFlow and Cloud TPUs. The mission might be introduced as a browser based mostly utility utilizing Flask. The deep studying prototype can course of steady audio information after which acoustically acknowledge the species.
The purpose of the mission once I began was to construct a primary prototype for monitoring of uncommon chook species in India. In future I want to broaden the mission to watch different endangered species as nicely.

Persona Labs’ Digital Personas
By Martin Andrews and Sam Witteveen, ML Google Developer Specialists (Singapore)
Over the past 3 years, Purple Dragon AI (an organization co-founded by Martin and Sam) has been growing real-time digital “Personas”. The important thing concept is to allow customers to work together with life-like Personas in a format just like a Zoom name : Chatting with them and seeing them reply in actual time, simply as a human would. Naturally, every Persona will be tailor-made to duties required (by adjusting the looks, voice, and ‘motivation’ of the dialog system behind the scenes and their corresponding backend APIs).The parts required to make the Personas work successfully embrace dynamic face fashions, expression era fashions, Textual content-to-Speech (TTS), dialog backend(s) and Speech Recognition (ASR). A lot of this was constructed on GCP, with GPU VMs working the (many) Deep Studying fashions and mixing the outputs into dynamic WebRTC video that streams to customers by way of a browser front-end.
A lot of the earlier years’ work focussed on making the Personas’ faces behave in a life-like means, whereas ensuring that the general latency (i.e. the time between the Persona listening to the person asking a query, to their lips beginning the response) is saved low, and the rendering of particular person pictures matches the 25 frames-per-second video price required. As you may think, there have been many Deep Studying modeling challenges, coupled with laborious engineering points to beat.
By way of backend applied sciences, Google Cloud GPUs have been used to coach the Deep Studying fashions (constructed utilizing TensorFlow/TFLite, PyTorch/ONNX & extra not too long ago JAX/Flax), and the real-time serving is finished by Nvidia T4 GPU-enabled VMs, launched as required. Google ASR is at present used as a streaming backend for speech recognition, and Google’s WaveNet TTS is used when multilingual TTS is required. The system additionally makes use of Google’s serverless stack with CloudRun and Cloud Features being utilized in a few of the dialog backends.
Go to the Persona’s web site (linked under) and you may see movies that reveal a number of features : What the Personas seem like; their Multilingual functionality; potential purposes; and so on. Nonetheless, the movies can’t actually reveal what the interactivity ‘looks like’. For that, it’s finest to get a stay demo from Sam and Martin – and see what real-time Deep Studying mannequin era seems like!
