Introduction to ChatGPT and its Interface

Let's start with the basics: getting familiar with ChatGPT's interface. At the top left-hand corner, you have the GPT selection menu. Here, you can choose from models like GPT-4, which includes browsing and analysis capabilities, or the free GPT-3.5. The interface allows you to explore custom-built GPT models and interact with them effectively.
Practical Application: Use the newest model for tasks requiring internet browsing and advanced data analysis. For instance, when you need to perform a complex analysis, selecting GPT-4 ensures access to the necessary tools.
Tip: Use keyboard shortcuts like "copy last code block" and "copy last response" to streamline your workflow. Rename chats with emojis for better organization and recognition.

Custom GPTs

Custom GPTs are models built on top of ChatGPT for specific functions. You can explore these through the "explore" menu, which is your central hub for accessing both pre-built and user-created GPTs. For this course, we have a dedicated GPT called "data analytics" designed to quiz you on the course content.
Practical Application: Create a custom GPT to quiz yourself on new material. This reinforces learning and helps you retain information better.
Tip: Regularly visit the "explore" menu to find new GPTs that might aid in your specific tasks.

Basic Prompting Techniques

Successful interaction with ChatGPT hinges on effective prompting. This involves providing both context and task in your prompts. For example, "Explain what prompting is in the style of Dr. Seuss" is more effective when you add context like "I am a 5-year-old." This guides ChatGPT to tailor its response appropriately.
Practical Application: When asking ChatGPT to summarize a complex topic, specify the audience (e.g., "explain to a high school student") to get a tailored response.
Tip: Develop a personal context statement that you can use consistently to improve the quality of ChatGPT's responses.

Custom Instructions

Custom instructions in ChatGPT settings allow you to pre-define your context and preferred response formats and tones. This eliminates the need to include these in every new chat. You can specify what ChatGPT should know about you and how you'd like it to respond.
Practical Application: Set up custom instructions to ensure ChatGPT always responds in a concise manner with a professional tone, especially useful for business communications.
Tip: Enable "for new chats" to automatically apply custom instructions, saving you time and effort.

Advanced Data Analysis Plugin

The Advanced Data Analysis plugin is a powerful tool for data analysts, enabling file uploads for analysis and insight generation directly within ChatGPT. Available only with GPT-4, this plugin allows for data analysis, statistical analysis, data processing, predictive modeling, and custom queries.
Practical Application: Use the plugin to upload a CSV file containing sales data and generate insights such as trends and forecasts.
Tip: Be aware of the limitation where the environment running the Python code and storing uploaded files can time out. Re-upload files if necessary.

Connecting to Data Sources and Importing Data

The course covers importing data sets into ChatGPT using the Advanced Data Analysis plugin. Supported file types include CSV, Excel, and JSON. With specific prompting, more file types can be handled.
Practical Application: Upload a JSON file containing customer feedback and use ChatGPT to analyze sentiment trends.
Tip: Ask ChatGPT about the columns and descriptive statistics of your data set to get a quick overview.

Exploratory Data Analysis (EDA)

Performing EDA using ChatGPT involves generating descriptive statistics on numerical and categorical columns. Key metrics include count, mean, standard deviation, min/max, unique values, and frequency. Visualizations like bar charts, line charts, histograms, and box plots are essential.
Practical Application: Use EDA to understand customer demographics by analyzing categorical data such as age groups and spending habits.
Tip: When creating visualizations, ensure readability by formatting them properly, using color schemes and removing clutter.

Four Types of Data Analytics

Descriptive Analytics: Summarizes historical data to identify trends. Example: Analyzing how sales have trended over the past year.
Diagnostic Analytics: Understands why certain events or trends occurred by looking at past data. Example: Investigating a dip in customer satisfaction in a specific month.
Predictive Analytics: Forecasts future outcomes using historical data and statistical techniques. Example: Building a model to predict future sales based on past trends.
Prescriptive Analytics: Recommends actions to achieve desired outcomes. Example: Suggesting marketing strategies based on customer behavior analysis.

Predictive Analytics in Detail

Building a machine learning model within ChatGPT using the Advanced Data Analysis plugin involves defining the target variable and input features, suggesting suitable models, and evaluating performance using metrics like RMSE.
Practical Application: Define the target variable as customer churn and input features as customer demographics and purchase history to predict future churn rates.
Tip: Test your model by providing specific input values and getting predictions to validate its accuracy.

Prescriptive Analytics in Detail

Building a recommender algorithm within ChatGPT involves taking a list of skills and recommending job titles and companies that maximize median yearly salary.
Practical Application: Use a data set to recommend career paths for employees based on their skills and industry trends.
Tip: Leverage the "description tokens" column to align skills with job titles effectively.

Advanced ChatGPT Concepts

Understanding advanced concepts like context length and tokens, hallucinations, bias, and temperature is crucial.
Context Length and Tokens: Limits the amount of text ChatGPT can process. Tokens include words, whitespace, punctuation, and emojis.
Hallucinations: Occur when ChatGPT provides incorrect or fabricated information. Prevent this by cross-verifying information.
Bias: Be aware of potential bias in responses.
Temperature: Controls the randomness of responses. Experiment with different settings for varied outputs.

Best Practices for Prompting

Use a six-part formula: Task, Context, Exemplar, Persona, Format, and Tone.
Exemplar: Provide examples of the desired output format.
Persona: Instruct ChatGPT to adopt a specific voice.
Format: Specify the visual presentation of the output.
Tone: Define the manner and attitude of the response.
Tip: Apply these elements to refine your prompting skills and enhance response quality.
