audio-recognition icon audio-recognition

This notebook tries to preprocess the .wav files and by generating their spectrogram, we can turn the problem into a image classification problem.

autoencoder_based_feature_extraction icon autoencoder_based_feature_extraction

Deep learning project on signal processing. This research is on human motion monitoring data from wearable sensor. Building a convolutional Autoencoder to decode the input signal. The encoder output can be used as compressed representations to determine the correctness of execution.

competitor_analysis icon competitor_analysis

This app integrates e-bike’s data from different retail online stores and amazon.com, and provide interactive competitor analysis on price recommendations and feature comparisons for dynamic pricing and future product developments.

customerservice_qc_report icon customerservice_qc_report

Using SQL-like functions to summerize defective products/ types, customer care agent breakdown, and freashdesk type breakdown

facebook_prophet_modeling_on_sales icon facebook_prophet_modeling_on_sales

In this project, the researcher try to explore the Facebook's Prophet model.Not like general autoregressive model, the y(t) is related by t itself.

inventory_planning_amazonvc_breakdown icon inventory_planning_amazonvc_breakdown

This notebook breaks down Amazon Brand Analysis into per-product inventory, Open purchase order, and forecasts with customized summaries and product details to aid inventory planning.

minitimeseries icon minitimeseries

Create a multi-output machine learning dataframe and apply LSTM/Bidirectional LSTM with Tensorflow early stopping/model Checkpoint callbacks to predict the temperature for next several days

polars_reference icon polars_reference

a quick data analysis reference by using polars dataframe instead of pandas on blending sheets and summerize.

qb_item_quick_report icon qb_item_quick_report

Use transactions in Quickbooks item quick report for favorable supply planning, including sales projection from previous year sales grouped by customers, Croston's method intermittent daily demand forecasting, and ARIMA forecasting on converted monthly sales. Comparing with all transactions, these analysis will focus on mainly domestic transactions for benefits on inventory planning at Phoenix location.

recommendation_system_mf_deep_learning_modeling icon recommendation_system_mf_deep_learning_modeling

This project is trying implement recommendation system with Keras API by collaborative filtering methods. The first model is a simple matrix factorization, which the ranking from user i to product j can be expressed as ui dot pj where elements u and p belong to decomposed user and product matricies.

sentiment_analysis_on_amazon_review icon sentiment_analysis_on_amazon_review

Preprocess the 500K amazon reviews from raw texts into squences and fit a LSTM model with embedding layer, to determine a new review, tweet, or any product related message positive, negative.

sku_mapper icon sku_mapper

The VB script is to help to unite same products from different channels for summary and further analysis

tensorflow_object_detection icon tensorflow_object_detection

Disclaimer: This notebook is edited from Lazy Programmer, the instructor of Deep Learning: Advanced Computer Vision for learning and experimental use only.

wordseqencedecoding icon wordseqencedecoding

This notebooks, we train a seq2seq decoder model with teacher forcing. Then use the trained layers from the decoder to generate a sentence.
