Depression is among the most prominent mental illnesses, affecting more than 300 million people globally, according to the World Health Organization (WHO).

Beyond the potentially devastating personal and social effects of depression, the economic costs related to this mental health issue have substantially increased in recent years. In fact, it’s currently estimated to cost the global economy over $1 trillion USD each year.

Since we founded Fritz AI in late 2017, we’ve seen tremendous growth in the Boston-area tech scene. What was once a city whose tech economy centered on academia, biotech, and robotics, Boston has flourished into one of the most attractive locations for all kinds of tech start-ups, early- and late-stage alike.

Image Classification and Convolutional Neural Networks

Over the past few years, deep learning techniques have dominated computer vision. One of the computer vision application areas where deep learning excels is image classification with Convolutional Neural Networks (CNNs).

Transfer learning, an approach where a model developed for a task is reused as the starting point for a model on a second task, is an important approach in machine learning. Prior knowledge from one domain and task is leveraged into a different domain and task.

Transfer learning, therefore, draws inspiration from human beings, who are capable of transferring and leveraging knowledge from what they have learned in the past for tackling a wide variety of tasks.

Lens Studio allows you to import and add audio to your lenses. Adding audio to your lenses enhances the nature of the lenses by enabling the viewer more interaction. It can be added in behavior scripts as a response and even in animations.

Behavior scripts in lens studio enable you to make interactions in your lenses by defining a trigger type and a response for that trigger.

OpenCV is a powerful tool for doing intensive operations in real-time, even for resource-limited mobile devices. Throughout a couple of tutorials, we’re going to create an Android app that applies various effects over images.

Deep Learning algorithms are excellent at solving very complex problems, including Image Recognition, Object Detection, Language Translation, Speech Recognition, and Synthesis, and include many more applications, such as Generative Models.

However, deep learning is extremely compute intensive—it’s generally only viable through acceleration by powerful general-purpose GPUs, especially from Nvidia. Unfortunately, mobile devices have very limited compute capacity; hence, most architectures that have been very successful on desktop computers and servers cannot be directly deployed to mobile devices.
