1stEURASIP-GAIPDM Seasonal School on Learning from Signals, Images, and Video HACKATHON-I Organizers: C. Kotropoulos M. Ntemi G. Karantaidis I. Sarridis E. Gionanidis
Tourism Recommendation Problem formulation: Recommend Places of Interest (POIs) using adaptive hypergraph learning. Input: POIs, which are represented by geo-clusters. Output: optimal ranking vector f. The sorted f contains the recommended POIs in descending order. Recall-Precision curve. Research ideas: Fine tuning of weight matrix W parameters. Fine tuning of incidence matrix H parameters. Combine W and H matrix updates. More ideas and detailed descriptions can be found in README.txt file.
PricePrediction Problem: Given the past airfare prices predict the next price Dataset: 27 routes. 1 route departure from New York, 26 from European cities 14 arrival to Athens, Greece, 13 arrival to Thessaloniki, Greece Input: " days_until_flight, departure, arrival, ticket_price " Output: airfare price prediction Approaches: Collaborative Kalman filter, Particle filter, LSTM NN, etc.
Hotel Rating Prediction Problem: anticipate the ratings that will be given to hotels from users with similar taste Dataset: 196,536 ratings from 170,187 users and 1,097 hotels in Santorini, Greece Input: "hotel_id, user_id, rating, date Output: Hotel rating Approaches: Matrix factorization techniques, Collaborative Kalman filter, Collaborative Deep Learning etc.
Natural Language Processing Problem: given a sentence (or text) in one language, find the translated one in another language. Dataset: pairs of sentences (192,881) in English and in German e.g., I am safe / ich bin sicher Input: the text in the input language Output: the translated text Approaches: Statistical Machine Translation, Neural Machine Learning, Rule-based and corpus-based machine translations
