Essay On Automatic Diagnosis For Cancer - 1155 Words

Automatic diagnosis for cancer is a ongoing topic of research. Previous research have been conducted on breast cancer diagnosis. Doyle et al. [9] investigated the classification of breast cancer histopathology from textual, nuclear architectural features and images. Classification of benign and malignant histopathological im- ages based on 10 syntactic structure features, extracted after the Gabor filter had been applied was used by van Diest et al.[10]. The usage of Support Vector Ma- chines (SVMs) on relevant numerical features extracted from histopathological images in a semi-automatic fashion has also yielded very promising results[11]. George et al.[12] developed an intelligent remote detection and diagnosis system for breast cancer†¦show more content†¦tasks[15][16][17]. However, deep CNNs often have a number of parameters so large that it cannot reasonably be trained without a very large dataset. Medical imaging datasets are often not sufficiently large enough to train a deep CNN model from scratch adequately. Thus, the usage of transfer learning in medical imaging has been explored[18]. Transfer learning seeks to transfer knowledge between large source and target domains[5]. For CNNs, this is often done by pre-training a CNN model with a large dataset, then re-training the model with the smaller target dataset[19]. Yosinski et al.[20] showed that features in deep neural networks, in particular those learnt in bottom layers of a CNN are transferable, and fine- tuning the entire CNN model with the target dataset improves the performance of model. Shin et al.[18] demonstrated that the performance of deep CNNs on several CADe problems can consistently improved by transfer learning from the large scale natural image dataset, ImageNet. 3 3.1 Approach Dataset The dataset used for training and evaluation is the benchmark BreakHis dataset[7]. It contains 7909 breast cancer histopathology images acquired from 82 patients. These images are labeled either †Benign† or †Malignant† and can be of four different resolutions (40X, 100X, 200X, 400X). The dataset is subsequently sep- arated into five folds.

Many people have heard the work autism, but could not define it if asked. Two essays I recently came across, â€Å"Joey: A ‘Mechanical Boy’† written by Bruno Bettelheim and â€Å"Thinking in Pictures†, written by Temple Grandin, share the common topic at hand, autism. Both essays talk about the struggles autism brings toRead MoreEthical Issues in the Pharmaceutical Industry2511 Words   |  11 PagesNo one can deny that the pharmaceutical industry has made significant contributions to human progress. The pharmaceutical industry has been responsible for drugs that have saved millions of lives, cured many forms of cancer, and ensured that an AIDS diagnosis is no longer an automatic death sentence. Yet despite this there are questions that the public has on whether the industry has been fulfilling their social responsibility. There are many ethical questions that need to be addressed on how theRead MoreThe Risks And Hazards Associated With Risk Reduction And Safety Will Be Discussed2175 Words   |  9 Pagesexamining pregnant patients, as the health of both the mother and foetus is considered.

Such a solution would also reduce the chance of miscounting and allow for the automatic tracking of First-In-First-Out inventory rotation procedures to reduce wastage of fresh produce.

We have al- ready noted the sharp distinction made in this school between the formulation of strategies on one hand and their implementation on the other. Consistent with classical notions of rationality—diagnosis followed by prescription and then action—the design school clearly separates thinking from acting. Central to this distinction is the associated premise that structure must follow strategy. It appears to be assumed that each time a new strategy isRead MoreProject Mgmt296381 Words   |  1186 Pagesa pharmaceutical organization could have a program for curing cancer.
