Over the past few years, deep learning has become another trendy word. It is mostly used in a business language when the conversation is about Machine Learning, Artificial Intelligence, Big Data, analytics, etc. Currently, it is showing great promise when it comes to developing the autonomous, self-teaching systems which are revolutionizing many industries. Therefore I decided to write an article about deep learning startups, use cases and books.
Deep Learning was developed as a Machine Learning approach to deal with complex input-output mappings. Deep learning crunches more data than machine learning and that is the biggest difference. Basically, if you have a little bit of data, machine learning is a good choice, but if you have a lot of data, deep learning is a better choice for you. Deep learning algorithms do complicated things, like matrix multiplications. They also learn high-level features, so in the case of facial recognition the algorithm will get the image pretty close to the RAW version in replication whereas machine learning’s images would be blurry. Another powerful feature is that it forms an end-to-end solution instead of breaking a problem and solution down into parts.
What is Deep Learning ?
But what is Deep Learning exactly ? Why has it become so popular ?
In simple words, Deep learning carries out the machine learning process using an artificial neural net that is composed of a number of levels in a hierarchy. For example, the network learns something simple at the initial level in the hierarchy and then sends this information to the next level. Next level takes this simple information, combines it into something that is a bit more complex, and passes it on the third level. This process continues as each level in the hierarchy builds something more complex from the input it received from the previous level.
Taking example of a dog, the initial level of a deep learning network might use differences in the light and dark areas of an image to learn where edges or lines are in a picture of a dog. The initial level passes this information about edges to the second level which combines the edges into simple shapes like a diagonal line or a right angle. The third level combines the simple shapes into more complex objects likes ovals or rectangles. The next level might combine the ovals and rectangles into paws and tails. The process continues until it reaches the top level in the hierarchy where the network has learned to identify dogs. While it was learning about dogs, the network also learned to identify all of the other animals it saw along with the dogs. It is a very good option to identify errors, in general it is a very fast and efficient way to analyze huge amount of information and save cost.
Deep learning use cases
Just like we mentioned, Deep learning startups successfully apply it to big data for knowledge discovery, knowledge application, and knowledge-based prediction. In other words, deep learning can be a powerful engine for producing actionable results. A good way to see all the potential of deep learning is looking at deep learning startups and see how big companies apply and use it.
Let’s start with the most known examples, Deep Learning is heavily used by Google in its voice and image recognition algorithms. Also, it is used by Netflix and Amazon to decide what you want to watch or buy next, and by researchers at MIT to predict the future.
How big companies and deep learning startups use it?
- Automatic speech recognition.
Just like we mentioned above, it is one of the most known feature of deep learning and big brands use it heavily, for example, Microsoft Cortana, Xbox, Skype Translator, Amazon Alexa, Google Now, Apple Siri, Baidu and iFlyTek voice search, etc. are based on deep learning.
- Image recognition.
As people prefer visual stuff, image recognition gained traction. It is used to analyze documents, pictures connected to a large database and make sure that the fraud is avoided.
- Natural language processing.
Natural language processing is another trendy topic and I even wrote an article about it. You may find it here. It is used by different companies in many industries, most used cases are: negative sampling, word embedding, constituency parsing, sentiment analysis, information retrieval, spoken language understanding, machine translation, contextual entity linking, writing style recognition, etc.
- Drug discovery and toxicology.
There are deep learning neural networks for structure-based rational drug design. Researchers enhanced deep learning for drug discovery by combining data from a variety of sources. Now, deep learning is used to predict novel candidate biomolecules for several disease targets, most notably treatments for the Ebola virus, etc.
- Customer relationship management.
It is used a lot in direct marketing for CRM automation. It is good to approximate the value of possible direct marketing actions over the customer state lifetime value.
- Recommendation systems.
Recommendation systems have used deep learning to extract meaningful features for recommendations. It has been applied for learning user preferences from multiple domains.
It is also used to predict gene ontology annotations, gene-function relationships and sleep quality based on data from wearables and predictions of health complications from Electronic health record data.
- Gesture Recognition.
Gesture Recognition is the latest addition in the area of machine learning which deals with recognizing the gestures made by human face. The signals that are emitted from the sensors are be able to detect the emotion on the basis of energy, time delay, and frequency shift. It is also able to identify the object and its characteristics.
19 Deep Learning Startups
Deep learning startups come up with absolutely amazing ideas and projects. Let’s look at the brightest ones, these examples are just a small sample of the many companies that are using deep learning to do innovative and exciting things.
Bay Labs is the first one on my list of deep learning startups. It is onamong the startups applying deep learning to medical imaging to help in diagnosis and management of heart disease. They want to push the limits of deep learning to make an impact on healthcare. By improving access, value, and quality to medical imaging, they hope to promote and advance healthcare in both the developed and developing world. At Bay Labs, they believe that deep learning has potential to dramatically impact the leading cause of death – cardiovascular disease.
Canary is a New York City-based deep learning startup with a mission to make people safer and more connected to their homes. Canary is the world’s first smart home security device for everyone. Canary contains an HD video camera and sensors that track everything from temperature and air quality to vibration, sound, and movement. It is controlled entirely from your smartphone, Canary alerts you when it senses anything out of the ordinary, from sudden temperature spikes that can indicate a fire, to sound and vibration that could mean an intrusion. Over time, Canary learns your home’s rhythms to send even smarter alerts. Watch video here.
BenchSci is a machine learning platform that helps biomedical researchers find the best biological compounds for their experiments. It was born as a result of common struggle with browsing millions of scientific publications in order to find the antibodies best suited for our experiments. BenchSci is a platform that extracts usage evidence from scientific papers and organizes it around antibodies. With BenchSci, scientists can find the best antibodies within minutes. Watch video here.
CarePredict is designed to solve a specific challenge in senior care: family, friends and caregivers of an elderly person may not notice the precursors to declines in health and hence do not intervene in time leading to hospital admissions of easily preventable issues. For example, a senior entering into a depressive phase will start having restless sleep patterns, loss of hygiene and changes in eating patterns several days before the episode. Carepredict is solving the continuous observation problem for the senior market with the very first wearable designed for seniors that tracks their activities of daily living, from waking up, bathing, sleeping, quality of sleep, to brushing teeth, eating, drinking, cooking and more. It gives useful insights. Watch video here.
