&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;&lt;b&gt;Cognitive Services&lt;/b&gt;
&lt;ul style=&quot;list-style-type: disc;&quot; data-ke-list-type=&quot;disc&quot;&gt;
&lt;li&gt;A suite of services with four main pillars: Vision, Speech, Language, Decision&lt;/li&gt;

&lt;/ul&gt;

&lt;li&gt;models use layers of algorithms in the form of artificial neural networks to return results for more complex use cases. Azure AI services are built on deep learning models.&lt;/li&gt;
&lt;li&gt;(모델은 인공 신경망 형태의 알고리즘 계층을 사용하여 보다 복잡한 사용 사례에 대한 결과를 반환. Azure AI 서비스는 딥 러닝 모델을 기반으로 함.)&lt;/li&gt;
&lt;/ul&gt;

&lt;ul style=&quot;list-style-type: disc;&quot; data-ke-list-type=&quot;disc&quot;&gt;

&lt;li&gt;(모델은 입력에 설명된 내용을 기반으로 새로운 콘텐츠를 생성할 수 있는 딥 러닝 모델의 하위 집합. OpenAI 모델은 언어, 코드 및 이미지를 생성할 수 있는 생성 AI 모델 모음.)&lt;/li&gt;

&lt;p data-ke-size=&quot;size16&quot;&gt;과거의 데이터 = 통계&lt;/p&gt;
&lt;p data-ke-size=&quot;size16&quot;&gt;미래를 예측 = 확률&lt;/p&gt;

&lt;ol style=&quot;list-style-type: decimal;&quot; data-ke-list-type=&quot;decimal&quot;&gt;

&lt;ul style=&quot;list-style-type: disc;&quot; data-ke-list-type=&quot;disc&quot;&gt;
&lt;li&gt;회기(Regression) : Label is a numeric value&lt;br /&gt;예시) 요일, 계절, 날씨를 기반으로 자전거 대여 수 예측&lt;/li&gt;
&lt;li&gt;분류(Classification) : :Label is a categorization (or class)&lt;br /&gt;예시) 임상 측정을 기반으로 환자가 당뇨병에 걸릴 위험이 있는지 예측&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;비지도학습(Unsupervised Machine Learning) : Training data is unlabeled
&lt;ul style=&quot;list-style-type: disc;&quot; data-ke-list-type=&quot;disc&quot;&gt;
&lt;li&gt;군집(Clustering) : Similar items are grouped togerther&lt;br /&gt;예시) 베기가스 및 연비 특성이 유사한 차량끼리 클로스터로 분리&amp;nbsp;&lt;/li&gt;
&lt;/ul&gt;

&lt;p data-ke-size=&quot;size16&quot;&gt;문자들이 담겨있는 배열 arr가 주어집니다. arr의 원소들을 순서대로 이어 붙인 문자열을 return 하는 solution함수를 작성해 주세요.&lt;/p&gt;
