The goal of a recommender system is to generate meaningful recommendations to a collection of users for items or products that might interest them. Many of the largest e-commerce websites are already using recommender systems to help their customers find products to purchase or download.

genetic algorithm based music recommender system
- 1. GENETIC ALGORITHM BASED MUSIC RECOMMENDER . (GAMR)
- 2. INTRODUCTION Users are usually looking for items they find interesting Website is a collection of these items Huge amounts of data available We propose a system using a combination of conventional techniques and genetic algorithm Used by E.commerce site
- 3. AIMS AND OBJECTIVES Generate Prompt meaningful recommendations responses and adaptation to changing preferences High recommendation accuracy Enriched user interface
- 4. WHAT IS RECOMMENDATION SYSTEM Internet-based software tools Provides user with intelligent suggestions Recommender systems for music data produce a list of recommendations Content-based filtering Collaborative filtering
- 5. CONTENT-BASED FILTERING Based on information and characteristics of the items
- 6. PLAN OF ACTION (Item profile+User profile+Prediction mechanism Item profile likes recommend items with similar content build recommend Good Life E.T Run This Town Gold Digger match Hip-hop Kanye west Rihanna… User profile
- 7. COLLABORATIVE FILTERING Predict items based on the items previously rated by other similar users Recommended items that are preferred by other people Example of a collaborative filtering technique.
- 9. LITERATURE SURVEYED Existing Systems Proposed system Focus on accessed items only Considers all items available in database Not prompt to immediate changes in user interest IGA prompts to immediate changes in user preferences Unable to learn from user actions and implement them Adapts to user actions to compute accordingly Accuracy is not great The offspring generated are quite optimal
- 10. GENERIC RS For a typical recommender system, there are three steps 1. User provides some form of input to the system. 2. These inputs are brought together to form a representation of the users likes and dislikes. 3. System computes recommendations
- 11. GENETIC ALGORITHM A genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems Use techniques inspired by natural evolution, such as replication, inheritance, mutation, selection, and crossover
- 12. GENETIC ALGORITHM PROCEDURE 1. Choose the initial population of individuals 2. Valuate the fitness of each individual 3. Repeat until termination 4. Select the best-fit individuals for reproduction 5. Breed new individuals through crossover and mutation 6. Evaluate the individual fitness of new individuals 7. Replace least-fit population with new individuals
- 13. FLOW CHART OF SYSTEM
- 14. SYSTEM ANALYSIS The proposed system is divided into three phases, namely, 1. Music Feature Extraction 2. Evaluation 3. Interactive Genetic Algorithm In our proposed system, IGA works in three steps: Selection,Crossover, and Matching.
- 19. SCOPE OF THE SYSTEM More than half the music now-a-days is downloaded The trend is bound to rise exponentially Virtually impossible to go through the heap of data and choose Recommendations from primary sources are too narrow They amount to a bulk of online sales across sectors These systems are attracting huge attention and investments from e-commerce sites

Hinweis der Redaktion
- We proposed a new recommender system for music data by combining the content based filtering technique with interactive genetic algorithmthe content based approach has some limitation such tha it focuses on only the accessed items and is not prompt to immediate changes in the potential interest of users.to overcome these limitations,we combine the content based filtering approach and genetic algorithm in our prposedsystGAs produces offspring(i.e;new solutions) by the combination of selected solutionswe proposed real-time genetic recommendation method in order to overcome the existing recommendation techniques are notreflect the current user`s intend. With the genetic algorithm newer solutions can be generatedproviding optimal solution each time when the algorithm is made to run, thus providingmutations. This method can be compared with the existing ones which lack the quality of providing accurate results.
- For a typical recommender system, there are three stepsThe user provides some form of input to the system. These inputs can be both explicit and implicit . Ratings submitted by users are among explicit inputs whereas the URLs visited by a user and time spent reading a web site are among possible implicit inputs.These inputs are brought together to form a representation of the users likes and dislikes. This representation could be as simple as a matrix of items-ratings, or as complex as a data structure combining both content and rating information.The system computes recommendations using these user profiles.
- WORKING:Apply genetic algorithm to music recommendation system. The system can detect and recommend appropriate songs which are suitable for user’s musical preference. And, the system requires pre-processing which is feature (i,e. tempo, chord, pitch, etc.) extraction from music. It based on shuffle operation. (i.e, play song randomly) At first time, the system recommends songs randomly and user cans judge’s song’s preference by controlling their devices or program. Just click the next song button.
- Description: This is the general list where all thesongs of different category is listed. The user canlisten to songs as well as rate them. Once userprovides ratings, user is directed to the recommendedlist of songs based on user preference
- Description: This is the final output page of therecommender system. This page displays the top tenrecommendations to the user based o his preferences.
