Abu-Saqer, Samy S. Abu-Naser, Mohammed O. Al-Shawwa Faculty of Engineering and Information Technology Al-Azhar University Gaza – Palestine Abstract: Fruit has been recognized as a good source of vitamins and minerals, and for their role in preventing vitamin C and vitamin A deficiencies. People who eat fruit as part of an overall healthy diet generally have a reduced risk of chronic diseases. Fruit are important sources of many nutrients, including potassium, fiber, vitamin C and folate (folic acid). One of important types of fruit is Grapefruit . Grapefruit is a tropical citrus fruit known its sweet and somewhat sour taste. It's rich in nutrients, antioxidants and fiber, making it one of the healthiest citrus fruits you can eat. Research shows that it may have some powerful health benefits, including weight loss and a reduced risk of heart disease. In this paper we presented a system that recognize the two types of Grapefruit Pink and white based on deep learning using python on colab editor . This system may help people to automate their factories , restaurants or anything else need to classify these two types for different use . Keywords: Grapefruit ,Deep Learning, Classification, colab , python. INTRODUCTION Grapefruit is a citrus fruit with a flavor that can range from bittersweet to sour. It contains a range of essential vitamins and minerals. People can consume the fruit whole or as a juice or pulp. The grapefruit first appeared in the 18th century, as a result of crossing a pomelo and an orange. People called it "grapefruit" because it grows in clusters, similar to grapes. The nutrients grapefruit contains may help promote healthy skin and protect against various conditions. They may also play a role in weight maintenance.

Such algorithms develop a layered, hierarchical architecture of learning and representing data. This hierarchical learning architecture is inspired by artificial intelligence emulating the deep, layered learning process of the primary sensorial areas of the neocortex in human brain, which automatically extracts features and abstractions from underlying data [3, 4, 5]. Based on [6, 7], DL algorithms are useful when it comes to dealing with large amounts of unsupervised data and naturally learn data representations in a greedy layer-wise method. Figure 2 Deep learning has dramatically improved the state-of-the-art in many different artificial intelligent tasks like object detection, speech recognition, machine translation . Its deep architecture nature grants deep learning the possibility of solving many more complicated AI tasks . As a result, researchers are extending deep learning to a variety of different modern domains and tasks in additional to traditional tasks like object detection, face recognition, or language models. TYPES OF MACHINE LEARNING ALGORITHMS Machine learning algorithms are organized into taxonomy, based on the desired outcome of the algorithm. Common algorithm types include: •Supervised learning --where the algorithm generates a function that maps inputs to desired outputs. One standard formulation of the supervised learning task is the classification problem: the learner is required to learn (to approximate the behavior of) a function which maps a vector into one of several classes by looking at several input-output examples of the function. •Unsupervised learning --which models a set of inputs: labeled examples are not available. International Journal of Academic Information Systems Research (IJAISR) ISSN: 2643-9026 Vol. 4 Issue 1, January – 2020, Pages: 1-5 www.ijeais.org/ijaisr 3 •Semi-supervised learning --which combines both labeled and unlabeled examples to generate an appropriate function or classifier. •Reinforcement learning --where the algorithm learns a policy of how to act given an observation of the world. Every action has some impact in the environment, and the environment provides feedback that guides the learning algorithm. •Transduction --similar to supervised learning, but does not explicitly construct a function: instead, tries to predict new outputs based on training inputs, training outputs, and new inputs. •Learning to learn --where the algorithm learns its own inductive bias based on previous experience. The performance and computational analysis of machine learning algorithms is a branch of statistics known as computational learning theory. Machine learning is about designing algorithms that allow a computer to learn. Learning is not necessarily involves consciousness but learning is a matter of finding statistical regularities or other patterns in the data. Thus, many machine learning algorithms will barely resemble how human might approach a learning task. However, learning algorithms can give insight into the relative difficulty of learning in different environments. This paper organized as follow :in the first part we will talk about our objectives from this research , then we will talk about our dataset which we used to train our model and we will talk about it self then our system evaluation and result from testing our network .
