Dharma Institute has made great achievements in three technical fields: voice intelligence, language technology (natural language processing), machine vision and platform construction.
Achievements LibriSpeech intelligence 2065438+In June, 2008, Ali Dharma Institute opened a new generation of speech recognition model (DFSMN), which is the largest free speech recognition database in the world.
Conduct a public test of. Compared with the most widely used LSTM model in the industry, the DFSMN speech recognition model has faster training speed and higher recognition accuracy. Based on the DFSMN model, Ali AI has developed.
In the DFSMN-CTC model, the speech error rate is greatly reduced and the decoding efficiency is improved by 6 times.
The achievements in language technology are made by the machine translation technical team of Dharma Institute, which has reached 48 people.
A language translation direction, supporting Russian, Spanish, French, Arabic, Turkish, Thai, Indonesian, Vietnamese and other languages; Among them, e-commerce covers most language directions and scenarios, surpassing Google and Amazon, with daily calls 17.9.
A billion times. Ali's machine translation technology is not only used for e-commerce full-link service, but also widely used in a series of products such as rookie logistics clearance, Alibaba Cloud international community, flying pig travel translation assistant, nail social oral translation and so on.
Achievements in machine vision 2065438+In July 2009, Ali AI won the first place in the online image classification task in LPIRC (Low Power Image Recognition Challenge) held by CVPR 20 19, with a time of 23 ms
Single image classification speed, 10 minute to classify 20000 images. On the training data set used in the challenge, it reached 67.4%.
The classification accuracy is 3.5% higher than the official baseline.

A "recursive exploration dialogue model" is proposed, which integrates image recognition, relational reasoning and natural language understanding. By using tag information efficiently, we can learn to imitate the thinking mode of human cognitive complex scenes, effectively identify the entities and their relationships in pictures, infer the content of events described in pictures, and effectively model the context to understand the questions and real intentions raised by human beings and give natural and accurate responses.
How powerful is the Dharma Institute? Ma Yun said that Alibaba may not have it, but the Dharma Institute can stay. Judging from what Ma Yun said, you can imagine how powerful the Dharma Institute is.
The research direction of Dharma Institute is the future market development direction and high technology, and it may not see much achievement in the short term, but once the research is successful, the change will be enormous.
