Ranking is an important task in information retrieval and has gained much attention in recent years. Among the most used strategies, machine learning has achieved important results. The current work proposes a new machine learning based ranking algorithm, the MLM-RANK. MLM-RANK is based on the recently proposed Minimal Learning Machine (MLM). MLM is a(More)
Short-text classification is a challenging natural language processing problem. Beyond classification accuracy, another issue refers to the dimensionality of the feature vectors used for classification. This is especially important for embedded applications with hard constraints of computational power and memory. To deal with such problems, many techniques(More)
