===== Ricevimento Studenti - Question time =====

== Italiano ==
Come indicato in tabella, l'ufficio si trova all'interno dell'**Area della Ricerca di Pisa**. Per raggiungere l'area fate riferimento alla seguente {{:informaticaumanistica:bpw:raggiungerearea.png?linkonly|mappa}}. Una volta arrivati nell'area, per raggiungere il mio ufficio dovete passare o dall'ingresso 19 o dal 20, come mostrato [[http://hpc.isti.cnr.it/wp-content/uploads/2014/09/cnr.png|qui]]. \\ **NOTA BENE:** a meno di eventi eccezionali le porte dei due ingressi sono chiuse. Per poter accedere avete due possibilità:
  - Lasciate un vostro documento alla guardiania chiedendo un badge visitatore (soluzione da preferire);
  - Entrate e mi telefonate (solo nel caso in cui la guardiania avesse terminato i badge);

As it is reported in the table below, the teacher's office is inside the **Pisa Research Campus**. To reach it, please refer to this {{:informaticaumanistica:bpw:raggiungerearea.png?linkonly|map}}. Once arrived, to reach my office you should use either entrance 19 or 20. As shown [[http://hpc.isti.cnr.it/wp-content/uploads/2014/09/cnr.png|here]]. **NOTE:** doors are often closed. To get into the building you have two options:
  - Request a visitor badge providing your ID to the officer (preferred option);
  - Enter inside and call me (only when the officer has no more badges for visitors;

===== Scopo del Corso - Aim of the course =====

== Italiano: ==
Il Data Mining sui Big data è oggi un’area di ricerca molto attiva. L'applicazione delle attuali metodologie analitiche e strumenti software su un singolo personal computer non può gestire in modo efficiente dataset di grandi dimensioni. Le piattaforme di calcolo distribuito sono una soluzione scalabile per il big data mining, attraverso la scomposizione del problema in operazioni più piccole che possono essere eseguite parallelamente su singoli processori / macchine. Il corso propone l’insegnamento di concetti base del paradigma di calcolo distribuito tramite MapReduce dal punto di vista teorico e pratico, in particolare ci si focalizzerà su Hadoop per lo sviluppo di competenze nell'uso di strumenti di calcolo ad alte prestazioni per il data engineering, l’analisi di dati e l’utilizzo di tecniche di data mining. Gli studenti impareranno come i classici algoritmi di data mining possono essere applicati sui Big Data usando Hadoop (Spark). Set di dati reali (e open source) verranno utilizzati per presentare esempi e per consentire agli studenti di costruire i propri progetti. Una metà delle lezioni consisterà in esercitazioni (laboratorio) e una metà delle lezioni sarà teorica.

== English:==
Mining with big data or big data mining has become an active research area. Running current analytical methodologies and software tools on a single personal computer cannot efficiently deal with very large datasets. Distributed computing platforms are a scalable solution for big data mining, obtained by dividing a large problem into smaller ones that are concurrently solved by many single processor/machine. This course aims at teaching the basic theoretical concepts behind the MapReduce distributed computing paradigm, and Hadoop in particular, and at building expertise in the practical usage of high-performance computing tools for data engineering, analysis and mining. In particular, the students will learn how classical data mining algorithms can be applied to Big Data using Hadoop (Spark). Real (and open source) datasets will be used to present examples and to let the students build their own projects. Half of the lessons will consist of practice (Lab), and half of the lectures.
