Actually,  I&#8217;m  based in Ireland and work at Deloitte Digital, my story with  WordPress  started in 2008 when I created my first professional project  since  then much happened, in 2012 I attended my first WordCamp as a volunteer, 2 years later I became one of the organizers of WordCamp S\u00e3o   Paulo. I have participated as a speaker in over 10 WordCamps in Europe and South America, always covering my favourite subject front-end technologies.&nbsp;<br>I&#8217;m always involved  supporting  local developer communities because I believe communities  are tools of  integration and social development.

But\u2026. how mortal developers and small and medium business can effectively use machine learn to improve their solutions?<\/p>\n\n\n\n<p>In this talk, we are going to discuss the basic concepts around ML and using high-level libraries in JavaScript to implement on ourWordPress Application, described as a friendly Machine Learning library ml5.js will be our entry door to the Machine Learning world.<\/p>\n\n\n\n<p>To wrap up the introduction journey, we will see how we can use ml5.js in a real project. As I mentioned before ml5.js is a Javascript library &#8211; the talk is focused on a front-end stack but is open for people who want to learn more about the basic concepts behind machine learning.<\/p>\n\n\n\n<p>Let&#8217;s get coding!!!<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<p style=\"text-align: center\"><a href=\"https:\/\/2019.thessaloniki.wordcamp.org\/%CE%B5%CE%B9%CF%83%CE%B9%CF%84%CE%AE%CF%81%CE%B9%CE%B1\/\"><button>Book your ticket<\/button><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Click here for the English version \u0397 \u03c4\u03c1\u03af\u03c4\u03b7 \u03bf\u03bc\u03ac\u03b4\u03b1 \u03bf\u03bc\u03b9\u03bb\u03b7\u03c4\u03ce\u03bd \u03b1\u03bd\u03b1\u03ba\u03bf\u03b9\u03bd\u03ce\u03bd\u03b5\u03c4\u03b1\u03b9 \u03c3\u03ae\u03bc\u03b5\u03c1\u03b1, \u03bc\u03b1\u03b6\u03af \u03bc\u03b5 \u03c4\u03b1 \u03b5\u03bd\u03b4\u03b9\u03b1\u03c6\u03ad\u03c1\u03bf\u03bd\u03c4\u03b1 \u03b8\u03ad\u03bc\u03b1\u03c4\u03b1 \u03c0\u03bf\u03c5 \u03b8\u03b1 \u03bc\u03b1\u03c2 \u03c0\u03b1\u03c1\u03bf\u03c5\u03c3\u03b9\u03ac\u03c3\u03bf\u03c5\u03bd. \u039c\u03ac\u03b8\u03b5 \u03c0\u03bf\u03b9\u03bf\u03b9 \u03b5\u03af\u03bd\u03b1\u03b9, \u03b3\u03b9\u03b1 \u03c4\u03b9 \u03b1\u03ba\u03c1\u03b9\u03b2\u03ce\u03c2 \u03b8\u03b1 \u03bc\u03b9\u03bb\u03ae\u03c3\u03bf\u03c5\u03bd, \u03ce\u03c3\u03c4\u03b5 \u03bd\u03b1 \u03ba\u03ac\u03bd\u03b5\u03b9\u03c2 \u03c4\u03bf\u03bd \u03c0\u03c1\u03bf\u03b3\u03c1\u03b1\u03bc\u03bc\u03b1\u03c4\u03b9\u03c3\u03bc\u03cc \u03c3\u03bf\u03c5 \u03b5\u03c0\u03b9\u03bb\u03ad\u03b3\u03bf\u03bd\u03c4\u03b1\u03c2 \u03c4\u03b9\u03c2 \u03bf\u03bc\u03b9\u03bb\u03af\u03b5\u03c2 \u03c0\u03bf\u03c5 \u03c3\u03b5 \u03b5\u03bd\u03b4\u03b9\u03b1\u03c6\u03ad\u03c1\u03bf\u03c5\u03bd \u03c0\u03b5\u03c1\u03b9\u03c3\u03c3\u03cc\u03c4\u03b5\u03c1\u03bf.<\/p>\n","protected":false},"author":14980497,"featured_media":5766,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[1254085],"tags":[29],"class_list":["post-2574","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-1254085","tag-speakers"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/thessaloniki.wordcamp.org\/2019\/files\/2019\/09\/WordCampThess-2019_SPEAKERS-GROUPED.jpg","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/posts\/2574","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/users\/14980497"}],"replies":[{"embeddable":true,"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/comments?post=2574"}],"version-history":[{"count":34,"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/posts\/2574\/revisions"}],"predecessor-version":[{"id":5845,"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/posts\/2574\/revisions\/5845"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/media\/5766"}],"wp:attachment":[{"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/media?parent=2574"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/categories?post=2574"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/thessaloniki.wordcamp.org\/2019\/wp-json\/wp\/v2\/tags?post=2574"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
