@SRobTweets created this pyramid to explain the idea.
As you move up the pyramid, less ML expertise is required, and you also don’t need to worry as much about the infrastructure behind your model.

@SRobTweets If you’re using Open source ML frameworks (#TensorFlow) to build the models, you get the flexibility of moving your workloads across different development & deployment environments. But, you need to manage all the infrastructure yourself for training & serving

⚖️ How to deal with imbalanced datasets?⚖️
Most real-world datasets are not perfectly balanced. If 90% of your dataset belongs to one class, & only 10% to the other, how can you prevent your model from predicting the majority class 90% of the time?

Since it is Day 10 of #31DaysofML it's perfect to discuss 1️⃣0️⃣ things that can go wrong with #MachineLearning Projects and what you can do about it!
I watched this amazing presentation by @kweinmeister that sums it all up

@kweinmeister 1️⃣ You aren't solving the right problem
❓What's the goal of your ML model?
❓How do you assess if your model is "good" or "bad"?
❓What's your baseline?
👉 Focus on a long-term mission with maximum impact
👉 Ensure that your problem is a good fit for ML

@kweinmeister 2️⃣ Jumping into development without a prototype
👉 ML project is an iterative process
👉 Start with simple model & continue to refine it until you've reached your goal
👉 Quick prototype can tell a lot about hidden requirements, implementation challenges, scope, etc

💁♀️ I thought today I would share a tip that has helped me in my #MachineLearning journey
💡The best way to learn ML is to pick a problem that you feel excited about & let it guide your learning path. Don't worry about the terms or tools, it's all secondary

Here's an example. Few weeks ago I wanted to live translate an episode of @GCPPodcast. The first question I asked myself was:
🤔 Does any video/audio translation API already exist?
🔹 If so - I would give that a try
🔹 If not, I would create it from scratch

@GCPPodcast Next, I started digging into the Media Translation API which would translate audio & video data.
My point is:
📌 You don't always need to create a model
📌 Save yourself time & resources by using the models that already exist (if they server your purpose)

📖 Learning Rate 📖 Also known as Step size
It's a scalar that is multiplied with gradient vector (which has the direction & magnitude) to provide the next value on the loss curve

👉 Smaller the learning rate the longer it will take to find the lowest loss value
👉 Large learning rate could overshoot the minimum
👉 You the learning rate to be just right (Goldilock's learning rate) to get the convergence value efficiently

Learning rate is one of the "Hyperparameters" that we tweak in machine learning algorithms. This is to tune the learning rate to efficiently get to the lowest loss value. There are more hyperparameters which we will get to later...

⬇️ Reducing Loss ⬇️
An iterative process of choosing model parameters that minimize loss
👉 Loss function is how we compute loss
👉 Loss function curve is convex for linear regression

A 🧵 👇
Calculating loss for every value of W isn't efficient: most common way is called gradient descent
👉 Start with any value of w, b (weights & biases)
👉 Keep going until overall loss stops changing or changes slowly
👉 That point is called convergence

As you probably already guessed, gradient is a vector with:
👉 Direction
👉 Magnitude
Gradient descent algorithms multiply the gradient by a scalar known as the learning rate (or step size) to determine the next point.

🕹 Training & Loss 🕹
In supervised learning training a model means learning good values for weights & bias from labeled examples. In doing so it attempts to find a model that minimizes loss. Process is called empirical risk minimization

📌 Loss indicates how bad model's prediction was on an example
📌 Loss = 0 if the model's prediction is perfect otherwise it's greater.
📌 Goal of training is to find weights & biases that have low loss, on average, across dataset

Squared loss or L2 loss is a popular Loss function that aggregates the individual losses
L2 loss for a single example = (observation - prediction)^2

⚡️Unsupervised learning ⚡️
Input data is unlabeled & the program learns to recognize the inherent patterns in the input data
Eg: Data across few people's eating habits
🔸Model input = 🍏🥦🧅🍓🥞🥖🍚
🔸Model output = cluster of vegetarian/vegan

When is unsupervised learning used?
🔸 On large datasets where annotating (labeling) data is costly
🔸 When we don't know how many classes might exist in the data
🔸 Cluster the data to apply classification on the individual clusters

@yufengg 1️⃣ Collect Data
📌Quantity & quality of your data dictate how accurate our model is
📌The outcome of this step is usually a table with some values (features)
📌 If you want to use pre-collected data - get it from sources such as Kaggle or BigQuery Public Datasets
