Data Science Meets Life Science: Using Deep Learning for Better Cancer Diagnosis

first_imgIn a recent study presented in March at the Strata Data Conference in San Jose, California, Dell EMC researchers Mauro Damo, Wei Lin, Ronaldo Braga, and William Schneider demonstrated that using machines to analyze medical images—specifically diseased human organs—can minimize medical errors and speed up disease diagnosis.Using more than 5,000 magnetic resonance images (MRI) scanned along the transverse plane from the Cancer Imaging Archive, the Dell EMC data scientists attempted to identify bladder cancer using a six-layer convolution neural network (CNN). Such networks have successfully identified faces, objects, and traffic signs, and are used to power vision in robots and self-driving cars.The Dell EMC study tracked four out of fourteen types of primary tumors—T2a, T2b, T3a, and T4a—in patients already diagnosed with bladder cancer. Algorithms were also used to identify significant differences among the images to assess what features could be relevant for bladder cancer detection. Bladder cancer, the fourth most common cancer in men, impacts 430,000 people and their families each year around the world. The direct medical cost of bladder cancer care was $125B in 2010 globally.To conduct the research, team members used powerful hardware and open-source software, including:Dell EMC PowerEdge servers with Intel Xeon E5-2680 processors @ 2.7GHz with 8 cores and 384 GBNVIDIA GRID K2 with 2 GPUsPython open-source script languageTensorFlow 1.4 open-source deep learning packageSimpleITK open-source image transformation packageResearchers learned that GPU and CPU memory are more relevant than cycles in hardware, and that out of memory errors are very common when working with medical data. For models that take weeks to run, it’s better to improve memory and cycles or use a distributed platform; otherwise, it’s preferable to have more memory to fit all your weights initialization and mini batch processes.Using the six-layer convolutional neural network (CNN), the study’s deep learning model improved Top 1 accuracy from 72.3 percent to 81.3 percent, showing the potential to explore similar techniques in practical applications. Researchers noted that more data in the early stages of cancer, the analysis of more types of primary tumors, and the use of independent CNN models for all planes (coronal, transverse, and sagittal) would likely improve results.To learn more about how deep learning can enhance research and processes in healthcare, financial services, retail, manufacturing, and other industries, explore Dell EMC Ready Solutions for AI, Machine and Deep Learning or contact your Dell EMC representative at 1-866-438-3622.

Bugojno Mountain Climbers reached the Mont Blanc

first_imgMembers of the Sector for Alpinist and climbing Sports of Mountaineering Society “Koprivnica”  from Bugojno reached one of the highest peaks in Europe – Mont Blanc in France, at the height of 4.810 meters. “We thank the families, friends and acquaintances, who were all the time with us.This morning at 7:45 am we climbed the Mont Blanc. Temperature was–15degrees, wind 50miles per hour, and it was a fantastic day. Everything was great, we all feel good, even though the last 36 hours, we slept only 20minutes”, wrote on her Facebook page Aida Muminović.Bugojno expedition started on 26th  July and marked a ten-day climbing adventure. Member of this expedition are Aida Muminović and her husband, Besim Muminović, Fahrudin Teskeredžić Teks and Zoran Čosić.“This is one of  the biggest success of the members for mountaineering and climbing sport. We are waiting impatiently their return to Bugojno“, said Emsada Babić, the President of  PD “Koprivnica”Bugojno Mountain Climbers have reached so far many peaks in B&H, Slovenia, Bulgaria and Austria(Source: klix.ba)last_img read more
