コース概要
Introduction
This section provides a general introduction of when to use 'machine learning', what should be considered and what it all means including the pros and cons. Datatypes (structured/unstructured/static/streamed), data validity/volume, data driven vs user driven analytics, statistical models vs. machine learning models/ challenges of unsupervised learning, bias-variance trade off, iteration/evaluation, cross-validation approaches, supervised/unsupervised/reinforcement.

I thoroughly enjoyed the training and appreciated the deeper dive into the subject of Machine Learning. I appreciated the balance between theory and practical applications, especially the hands-on coding sessions. The trainer provided engaging examples and well-designed exercises that enhanced the learning experience. The course covered a wide range of topics, and Abhi demonstrated excellent expertise by answering all questions with clarity and ease.

I appriciated the exercise that help me to undersand the theory and apply it step by step . as well the way the trainer explained everything in a simple and clear manner. It was easy to follow even though I'm not very experienced with Python, still, I didn't want to miss the opportunity to learn something that relly interests me. I also appreciated the variety of information provided and the trainer’s availability to explain and support us in understanding the concepts. After this course, machine learning concepts are much clear to me, and now I feel like I have a direction and a better undersantind of the topic.

短くシンプルにしてください。概念に基づいた直感的および視覚的なモデルを作成します (デシジョン ツリー グラフ、線形方程式、手動で y_pred を計算してモデルがどのように機能するかを証明します)。

ML を理解するという目標を達成するのに役立ちました。このトピックがいかに広大であるかは、3 日間のトレーニング後に明らかになるため、このトピックについて適切に紹介してくれた Pablo に多大な敬意を表します。また、レイテンシが非常に優れた、あなたが提供した仮想マシンのアイデアもとても気に入りました。これにより、すべての研究者が自分のペースで実験を行うことができました。
