ヨセミテの気候は地中海性気候であり、冬に降水(降雪)が集中し、そのほかの季節はほとんど雨が降らない(長く暑い夏の間の降水量は年間降水量の3%未満である)[18]。地形性大気上昇の効果により、約2400mまでは標高が上がるにつれて降水量が増し、そこを超えると頂上に向かって徐々に降水量が減少する。1200メートル地点の降水量は915mm、2600メートル地点では1200mmである。高地でも11月までは通常降雪は見られない。積もった雪は3月から4月初めまで残る[19]。 1日の最高気温は、標高2600mのトゥオルミ・メドウズで冬は-3.9°Cから夏は11.5°Cである。標高1560mのワウォナ・エントランスでは冬2°Cから夏19°Cである。1500m以下の低地では気温がもう少し高く、標高1209mのヨセミテ渓谷では最高気温は冬8°Cから夏32°Cである。一方標高2400mを超える高所では、夏の雷

My twin brother Afshine and I created this set of illustrated Deep Learning cheatsheets covering the content of the CS 230 class, which I TA-ed in Winter 2019 at Stanford. They can (hopefully!) be useful to all future students of this course as well as to anyone else interested in Deep Learning. • Types of layer, filter hyperparameters, activation functions • Object detection, face verification an
By Afshine Amidi and Shervine Amidi Overview Architecture of a traditional CNN Convolutional neural networks, also known as CNNs, are a specific type of neural networks that are generally composed of the following layers: The convolution layer and the pooling layer can be fine-tuned with respect to hyperparameters that are described in the next sections. Types of layer Convolution layer (CONV) The

By Afshine Amidi and Shervine Amidi Neural Networks Neural networks are a class of models that are built with layers. Commonly used types of neural networks include convolutional and recurrent neural networks. Architecture The vocabulary around neural networks architectures is described in the figure below: By noting $i$ the $i^{th}$ layer of the network and $j$ the $j^{th}$ hidden unit of the lay
By Afshine Amidi and Shervine Amidi Introduction to Supervised Learning Given a set of data points $\{x^{(1)}, ..., x^{(m)}\}$ associated to a set of outcomes $\{y^{(1)}, ..., y^{(m)}\}$, we want to build a classifier that learns how to predict $y$ from $x$. Type of prediction The different types of predictive models are summed up in the table below:
By Afshine Amidi and Shervine Amidi Introduction to Unsupervised Learning Motivation The goal of unsupervised learning is to find hidden patterns in unlabeled data $\{x^{(1)},...,x^{(m)}\}$. Jensen's inequality Let $f$ be a convex function and $X$ a random variable. We have the following inequality:
By Afshine Amidi and Shervine Amidi Classification metrics In a context of a binary classification, here are the main metrics that are important to track in order to assess the performance of the model. Confusion matrix The confusion matrix is used to have a more complete picture when assessing the performance of a model. It is defined as follows:

(ACM Trans. Graph. 34(6):189, 2015). We modify the original algorithm such that it efficiently produces meshes with many fewer singularities. Singularities in quadri
